Thread 'Polyester Cap Size: Red Vs Green'

This is one of those times where I realize I still have a lot to learn. I'm sorting through some caps and realized I have what look to be red metallized polyester capacitors as well as mylar greenies. I'm a bit confused why the red ones would be so much smaller than the green ones at the same voltage (100v). Below is a pic of a 220nf greenie, 390nf red, 470nf greenie, and a 680nf red. As far as I know, these are both very similar types of poly caps - why are the red ones so much smaller?

Also- I'm not certain exactly what time of capacitors these are (below). Can't...

Could anyone share links of where to buy greenie mylar film caps that have a consistent lead footprint (0.2" | 5.08mm) from 1--220nf (or 470nF)? Gotta be at <100V (like 25V or so) to meet that, but just wondering if those are out there. They go anywhere from ~3.8mm on the low value end to ~7.5mm at the high. And, yes, using box or MLCC caps have consistent lead pitches, but I'm wondering if there's a resource for these mylar caps.

Thanks
 
Maybe?

I bought lots of red ones from LCSC , search for polyester capacitor and then filter them with P=5.0mm plus 100V and under, and your search results will be glowing red like the east

The East Is Red (song) - Wikipedia

Bonus, the manufacturers are called stuff like Joey, Kyet, Knscha, Weidy etc

Thread 'Sourcing Compact Red Metal Film Caps'

Stompbox Parts has em, and I planned on giving those a shot. They're all 5mm spacing but not sure how much the actual size varies. No idea what brand.

Looks like the ECQ series was discontinued a while ago, which is a shame. Super compact even at high values.

I love box caps but I thought it would be nice to have an assortment of these too. Trying to find the most economical way to grab a few dozen of several values.

Those who use em - what do you like for compact 5mm reds and where do you source them from? Is SBP my best bet?

Ah, so looking at the listings they just form the leads to the correct pitch... greenies look like they only come in 100V, and because of their construction just get bigger and bigger. Womp.

Time to get one of those Exelta lead formers that cost the same as a Peak Atlas DCA75 /s
 
Maybe this helps, I've been making a few lists as LCSC lately.

I did go through the film caps, and they do have a number of the green ones. (yeah, I'm going for the aesthetic of the cheap-as-green caps) They do have them, but with leads bent to fit the 5mm pitch.

It looks like the values for the orange-brown varietals is wider, yeah.
