SOT-23 to SOIC adapters?

[MichaelW]

I have a project that needed SMD TL074's and I accidentally ordered the SOT-23-14 ones from Mouser.
Didn't notice it until today when I went to solder it.......uhhh.....it's the wrong size.....

I re-ordered the SOIC 14 ones from Mouser but here's my question, wtf am I going to do with a bunch of itty bitty TL074's I have now? Heh...

Does anyone know if they make an adapter board from SOT-23-14 to either SOIC-14 or DIP 14 so I can use these at some point?

TIA!

Send me a link to the part you ordered, I'll make an adapter.

 

[MichaelW]

Oh man, I'm getting a crash course in freaking SMD package sizes and my ignorance is glaring.....

Ok, these are the ones I have from Mouser.

Will this adapter work to convert it to DIP14?

I can't seem find the difference between "SSOP" and "SOT-23".

Send me a link to the part you ordered, I'll make an adapter.

Don't rush, I already re-ordered the correct SOIC-14 ones. Can you use some teeny tiny TL074's? You're welcome to them I have 6 of them.

 

[Robert]

I don't think that one will work if I'm looking at the correct footprint in the datasheet.

Can you snap a pic of one of the ICs you have?

I think I might have some....those are SOT-23-thin-14

 

[Robert]

Yep, those are tiny.

Overlaid with a SOIC-14 and DIP-14 for comparison.

Is that a new automotive package? That's an odd package. How is it different than a TSSOP? They both seemingly have 0.5mm pitch.

Oh wow, that is tiny. The smallest I've worked with (by hand) is QSOP with 0.635mm pitch.

I think the "T" denotes a lower height package.

 

[benny_profane]

I think the "T" denotes a lower height package.

Yeah, I think that's right. That's starting to get to exposed pad and ball-grid array territory. There's (confusingly) also a lot of package width variance between everything.

 

[Robert]

That SSOP is 0.65mm pitch, the SOT-23-14 is indeed 0.5mm.... which does bring up a good question.

Who wants to solder that thing?

Really wouldn't be that bad to be honest... You could just flood the pins with solder then wick off the excess.

 

[benny_profane]

Yeah, I honestly don't think it'd be that much worse than 0.635mm pitch. Drag with a chisel, wick excess, verify that there are no bridges (which is made much easier on a breakout board since you can use the DIP pads).

Here's a pic. TL071 SOIC8 on the right and an MMBFJ201 on the left of it. It's small.....sitting on a small post it note pad.

 

[Robert]

Yep, so the footprint I posted above looks to be correct.

Compared to a SOIC-8

Honestly, looking at these….nah…they don’t look to be of very good quality.

 

[MichaelW]

I think these are a good candidate for @fig's Easy Bake Oven I don't think I'd want to solder it even to an adapter.

 

[fig]

Not a problem. Send em.

I’ll pick up a stencil

It’ll be a piece of cake, with my EZ-Bake.

Yummy but tiny.
