 The Great Search brought you by DigiKey and Adafruit DigiKey. Thank you so much. More so than ever. The Great Search is now becoming the most popular segment across all of our shows because before back in the time of plenty it's like oh why do you need search for anything you can just find ships everywhere they grow on trees not anymore. So we tweet at us and used like pound the Great Search or at us at Adafruit whatever whatever ways let us know what you're looking for and we're also out there helping people and we saw we see things we help we saw this one you want to start with the tweet yes so we saw Tobias tweeted uh it was what's a Jerry who was who had like a head achy gif about like how you know she's working on design and can't find a part and Tobias says welcome to the club um anyone tps 27081 a uh for 15 bucks a piece usually 30 cents a piece so they're talking about how brokers are you know i've seen this like some brokers are are you know what i would call ethical it's like they'll charge a little bit more because it's rare but it's they're not going to charge a ridiculous amount we're seeing 10 20 yeah i like not putting people in you know you can resist anything from but temptation yeah and so i think right now there's a lot of temptation for a lot of folks who do brokering or parts to charge whatever no i have to actually redesign a couple more it's it's not a big deal i'm gonna do it anyways but it's like okay i'm not paying $15 for example i've seen it i've seen it i've had people quote me like five six seven eight dollars for parts that i'm like that's a 70 cent part like i can understand like hey 50 50 percent more you know oh like i want to make a couple bucks but i'm not going to pay it like if they find someone great but i'm not okay so what is and i'm saying you shouldn't pay either instead you should tag us on social media and we'll find you an alternative find the alternative and that's one thing um just because it's not the same part number that you're used to doesn't mean correct it's not something that you sometimes the part number is similar but sometimes it's not and we'll see here so this part is an i2t power switch normally 35 week lead time out of stock completely and yeah it used to be about 30 cents a piece so let's look at the datasheet and so we can see what we're what we're dealing with here because i've never used this this part so this is a 1 to 8 1.2 to 8 volt 3 amp p-fat high side low switch with level shift and adjustable slew light control so basically you can use this there's a v in coming in and then there's a gpa logic high and low you can put in a slew rate capacitor here a slew it resistor here to how much you want to feed this um this fat and it will turn on so it's basically like it's like a p-fat but it's like it's got a little bit extra in it just to make it special also it's 1.2 to 8 volts and it's 3 amps now look i may not be able to get you the exact same part but maybe it's within the specifications you need so let's use and i want to i want to highlight there's a couple things so there's new up here right below not in stock you can sign up for staff notification where they email you which which is we we did on ate a fruit so i hope they were inspired by and also find similar parts and they tell you how to use the similar parts tool which i will which i will tell you as well so let's look so um what do we want so we want an active part i don't want to say general purpose because i actually don't know we do want it with one output because we want it to be pin compatible we want to be one to one high side um i think i want the interface to be on off but i'm not sure voltage i'm not going to select because there might be a wider range or a range that's close enough so i'm not going to be too specific same with the current you know i'm not going to be too specific um i do want surface mount and i do want it to be in sot 236 or t-sot 236 so let's be similar um okay so another thing is down here these are now um all your specifications that you picked are also available down here that you can like turn on or off specific ones or you can delete the whole thing so you can see what more clearly what you searched for so let's we're gonna be very picky we only want ones in stock okay there's only 13 similar-ish parts um the output type so let's look at this this chip again to see what is the output type and it says it's a p-fat okay so let's go back here p-channel okay another eight um current output looks like there's a couple options uh voltage load i mean i think other than the 5.5 so the 5.5 i mean that might be good enough but um i'm going to assume that they want you know up to eight volts that's usually usually the high limit is what they want so i'm gonna turn those on let's look at more filters um okay so we have actually quite a few options right this is this is really good stuff and a lot of them are in stock so let's look at um they're all on off so it looks like we have a couple options a couple different current options so since we have a couple different current options i'm going to be i'm going to start getting picky and i'm going to say the other one was a 3 amp i'm going to assume that this person needs something that's about 3 amps so i'm going to pick only 2.8 and 3.3 amps okay so here's the two that came up one is uh almost the same 1.8 to 8 volts another one is uh 1.5 to 12 volts they both have an rds on of about 40 milli ohms uh checking this data sheet yeah you know 40 milli ohms or so that sounds about right and uh this one has slew 8 control although i'll say sometimes features aren't complete it depends on the person who entered it in if they like were you know they filled in everything so i always take the features as a grain of salt always check the data sheet and uh the pinout the package is the same which means i can have check if the pinout is the same so um these are both pretty cheap so let's look at the uh v shape part first so the v shape part so here's what i always like to see so the the application circuit see this it's it's basically the same as this it's very similar there's the r1 there's the v in on off r2 v in r1 on off what's slew slew is is how fast you want the current to go in it's a current limiting thing if something is slewed it means it's going to slowly ramp up if you have high slew it it spikes up there's times when you want it to react very fast you want a lot of current or something you want to reduce your inwards current because it could damage your components you slew in a sentence like that what you slew in a sentence like i want more slew because or well last last week we talked about op amps and we actually wanted a high slew op amp because we want it to react to volume changes very quickly high slew high slew um okay so for this one you see um the same pinout two and three or v out two and three or v out and one is the the bottom of this uh looks like yeah another MOSFET so yeah this one and then there's a return this shows the internal resistors but this looks actually almost identical i mean i will tell them you know you go and of course check that all the specifications match everything but this is very very promising um and there's uh 12 000 in in stock and then um for this one and notice that the part numbers are totally sometimes it's like oh and any 555 or ti 555 or an lm 555 they all have the same part number they have different prefixes these have completely different part numbers and prefixes and that's not like that's not unusual don't it's nice when they are but it doesn't necessarily mean it's bad if they're not it's it just depends on yeah everybody we're all gonna have to adapt at least you gotta be flexible yeah just because it's not the same part number doesn't mean you can't use it in fact that's gonna stop a lot of other people from either getting the parts they need or maybe even might some changes to their design but you gotta be you gotta stretch okay gotta do some flexing this one also rds on you know you see the specifications and then um you can see down here again the same thing there's an input two pins on the output pin six is you know you can connect to a capacitor out here one is listen this one has five yeah one is from the bottom of this fat um five is to the on off gate and v in is on pin four so this is actually one of the times when like there's actually two looks like good options uh both have about about 10 000 pieces of a stock indigki right now and um they're they're like 30 cents 20 cents even cheaper so you know if you can't get that ti part or if you're getting quoted like seven bucks ten bucks apart because don't do it don't look sometimes i agree sometimes there aren't any alternatives but i'll say something i've actually other than very very specifics chips that are like okay yes it's a one-off only this company makes this particular microcontroller um in this package and you need the exact microcontroller no then you might might not be able to get that but but analog and linear components and power components there's probably something out there there's probably something out there you're not you're not out of luck um there there's there's gold at the end of the rainbow so that's the great search so check it out send us your uh great crises your your bill material crises and we'll help fix them
