SIP sockets for thicker leads?

[slowpogo]

When building pedals I use SIP sockets all the time in case I want to try different parts or values.

But the standard size are too small for parts with larger leads (like higher voltage parts, old carbon comps and other "mojo" parts)

Are there SIP sockets that are made to accept bigger leads, perhaps with leaf springs or something? I've tried looking on Mouser but there are too many to sort through and it's often hard to tell from the info provided.

Use header pins, Dupont wire and breadboard.
Way easier to quickly audition/compare that way
Also, if you use long headers, often time you can get away with just inserting them and sitting the board on an angle on a non-conductive surface and the headers will make enough contact to audition a part without soldering.

Appreciate it, l’ve used a breadboard before but it doesn’t fit my preferred process. I typically will build the pedal using default parts, put it on my board and use it in a variety of scenarios, swap in different parts at my leisure if/when ideas occur to me as it sits on the board. Sometimes it’s a while before I get around to it, and the process itself might take 10 minutes or stretch intermittently over weeks, so going repeatedly to/from the workbench is not ideal. It’s just how I like to do things so I’m really interested in sockets that can accept thicker leads

I agree with @jwin615, and if you want you can certainly trim rows of Dupont headers and solder them directly to your pcb. Keep in mind they’re typically much taller than a SIP socket, although you can get short or angled ones if you look around. They’re way harder to snip off of rows than SIP sockets, so you can always start with a cheap multi-pack that has different combos.

Still just interested in sockets that fit bigger leads, as I explained above… if anyone has that info I’d appreciate it

Just quickly looking at the MillMax datasheets the 316 series seem to have larger internal dimms
0.38-0.64 vs 0.15-0.25mm
Edit to add, if you need bigger, I'd use Dupont headers like @Ginsly mentioned. Just get some 2 3 and 4 pin models and clip the center positions out. That would give you 2.5, 5, and 7.5mm spacings.

That's the pic in my post, m'man! Dupont headers. Although they can be used for breadboarding, you can indeed solder these to a board and cram a pretty big wire/lead in there. I've done it, that's how I know! If they're too tall Adafruit has shorter ones I think.

ah I misunderstood, thought it was meant to facilitate breadboarding. Thanks, I'll take a look!

edit: I measured the leads of some components I have, and a lot of them actually go beyond what the headers can handle (0.68mm). For example F&T caps, Russian PIO caps and larger carbon comps are all about 0.8mm. So the headers are unfortunately not a good solution either, in fact those components don't even fit in a breadboard!

I could solder thinner leads onto components and snip off the thicker ones, I've done this plenty of times. But it's a pain, ends up looking ugly and not something I want to do just to test a component I may not use permanently.

Sounds like you may need to layout your own PCBs.
How do you fit it in the footprint if it can't fit in the header footprint?
And whyare you using a f&t in a 9v circuit? Nm...
Dupont/JST are 0.64mm +-.1mm so i bet you could shove them in there.

You'd be surprised what you can make fit if you're determined, sometimes you just need to tilt or rotate something. I have a lot of bigger components leftover from amp and hi-fi projects and sometimes, they even seem to sound better. (F&T and Sprague make 25V caps which are not that huge) I also do my own vero layouts on occasion to allow for these. Especially with simple circuits like a Zvex SHO boost, there are only a few caps, why not go for that big mojo

I think typical breadboards have the same spec as the Dupont and other headers, but those leads won't fit in mine
