 The Great Search brought to you by Digikey and Adafruit. Every single weekly data user part of engineering to help you guess you find the things you want, need, gotta find, gotta substitute, gotta get going on in your designs on digikey.com. What is The Great Search of the Week this week? Okay, this week on The Great Search, I'm going to be talking about HDMI connectors for DVI boards, which is a very common connector that you've seen. Let's go over ahead and I'll show it off. As seen here on this Raspberry Pi computer, this is even HDMI licensed. One thing, you know, there's lots of articles you can read. So the HDMI standard contains like Ethernet and audio and DVI, the digital video signal. Be aware, if you actually use the HDMI marking, you owe a licensing fee. If you use the term HDMI, you will have to pay a licensing fee. So don't slap, if you're not actually using HDMI, if it's just the connector, it's a DVI connector. It doesn't have to be HDMI, but they clearly paid because they have the logo. But you've seen this before. Also, DisplayPort, by the way, is pin compatible. You know, there's all adapters you can use to make it pin compatible. And then DVI-D as well. Those are three connectors that use the same video and coding, you choose either one, but most people are familiar with this HDMI connector. And what's interesting about this HDMI connector is it's kind of universal, thankfully. We're gonna look on Digi-Key for an option. You'll notice when we get there that there's a lot of suppliers and they all have like one connector. Like, they're all the same, they're pretty much all compatible. I mean, I didn't manually check the pins, but like dollars to donuts, they're all gonna fit on the same footprint because it's pretty standardized. And another thing is that you see that the pins are surface mount, right? There's like 19 pins and they are SMT. And then the mounting tabs go through the circuit board and they actually, you know, this is a standard thing, the circuit board in there, they kind of poke out. And these connectors, so they're oval slots, let's go to the computer and I'll show you. You will, you know, you'll have to define the oval slots in your board. So you can see like in this CAD file, it's a little faint, but you can see it. There is the pad, which is a really nice big pad. I want big mechanical connection. And then you have the oval slot defined on the milling layer. Your board house should know what to do. They'll make a through-hole plated slot. And then make sure to also have the cream layer. Maybe I'll turn off the ground. So you'll see I have, it's hatched. Solder paste is deposited onto these pads, even though there's a slot in it. And then what happens is that when the connector is placed through these four pads, these through-hole, sorry, these through-hole tabs, go through the slots and kind of push the paste as they go that kind of like, you know, slot in, squish the paste in and the paste kind of hugs the connector as long as the slot, make sure the slot, you don't have too tight, but it should be like a fairly good fit. And then when you put it through the oven, you don't have to wave solder or selective solder it because that paste will, you know, the SMT pads will kind of get it into spot, into the right spot. And then the through-hole tabs will solder and wick into the slots. And you'll actually get a really good mechanical connection, even though you'd think like, oh, is this through-hole? Is this SMT-ish through-hole-ish? You can use wave or selective, but you don't have to. And I've done plenty of boards that use this DVI connector and you do not need to have a secondary process for them, which is a really nice design decision. I'm really glad that whatever consortium made this, the HDMI consortium that made this character design, they did a really good job. So let's go to Digi-Key. And this is an HDMI connector, but I'll show you also there's other connectors. You can go to USB DVI and HDMI. You know, these are kind of grouped together and it kind of makes sense. They're sort of similar connectors. Don't forget that HDMI does come in micro mini and like standard, huge HDMI. The micro, sorry, the micro HDMI is very small, but the mini looks deceptively like the large one. So just make sure you have the right connector when you're buying it. So let's go for active. So there are a couple different generations for the HDMI. I think they changed, you know, how much resolution they can pass. Honestly, I just, I'm not using Ethernet in this case or 4K. And let's see, I only want one port, which is the only thing that's selected. I do like the new Digi-Key that kind of gray out everything that wouldn't be selected. And then let's do normally stocking. And this only gives me about 42 options. So there's a couple of like funky stuff, like this is a panel mount one, but you'll also see a lot of like this and this, you know, these are equivalent and this one, these are the same. These are all very similar layouts and you can almost certainly use the same footprint for all of them, which is wonderful because you don't have to do it, just doesn't matter, you know, we can go between suppliers if you need to. There's also versions that are, this is, you know, panel mount, but like it's not, it's panel mount with the PCB. So this is mechanical stability, which is good if you have a design where you don't want like people, you know, they shove the HDMI port in and they kind of like jiggle it around. Then you don't want them to tear off the connector. A couple more panel mount ones or you don't want panel mount though. So let's go with, oh, and there's also micro. I'll just show you that really fast. Let's see, they do have a micro. So micro looks like HDMI, but it's tiny. Okay, so let's, let's skip that clear and then go back to HDMI. There's also, I did see there was one plug type, which is kind of cool. So if you wanted your board to plug directly into the HDMI port, this though, I believe it might be, it might hug the edge of the PCB. Let's see what they do here. Yeah, solder tails. So this is designed to have a 1.2 millimeter PCB go through and then you do have to, it's a weird process. I don't, I mean, maybe you could do paste on either side, but I think it's a hand soldering process. So I don't use this as much because it's kind of, it's, you know, it's more complicated than just pick and placing. So that's another option, but we're gonna go with HDMI and then receptacle. Nothing is, I think the Digikey search sped up when their web team walked it out. Okay, and then we want it to be, I think horizontal. Yeah, there's vertical that would be sticking up. Let's just see what that looks like. So this is the vertical style. Ooh, that's kind of funky. So this is definitely not pick and place. You're gonna have to, you know, you're gonna wave solder or selective solder this, but like it's like slim style. I agree. So let's do horizontal and we don't want flange. Mid-mount by the way means it's in the middle of the PCB. That also usually, I mean, sometimes it's like sunken in and you have like those legs that stick out sort of like spider legs, but I'm gonna go with the standard mount. So these are those standard HDMI connectors. Again, they're all gonna be compatible. They're all basically the same design. So let's look at some good pricing options. I'm gonna, you know, probably buy about 500 to start. So let's look at pricing at 500 pieces and I'm gonna exclude marketplace just cause I like to have instant shipping. And there's a lot and they, you know, they range and what are you paying for? I mean, you know, some of them are gonna have gold plates. Some of them are gonna be able to do HDMI 2.1. They might have different temperature ranges, but they're all gonna have the big, they're gonna basically, and some have different mating cycles, but they're basically all gonna be the same. You also might have a specific maker that you like, you really enjoy Amphenol or Molex or whatever, but you'll notice pretty much every company came in and was like, okay, we're gonna make one of these connectors. It's like a standard issue thing, but I do like CUI. So this week's product pick for the great search is going to be the HD0419 THTR, which is from CUI and it's, you know, a standard HDMI 2.1 19 position, half through hole, half surface mount, reflow compatible HDMI connector, a lovely board. And you can see they show you how to do those mounting ranks. You can do this in a pick and place process. That's a great search. Where is it?
