Digikey carries 118-PDB241-E420K-504B0-ND but I need 118-PDB241-E420F-504B0-ND

Greetings Digi-Key…

I need a couple of parts to repair a vintage computer. Specifically, two variable resistors, one 500K and the other 500M. I see a VERY similar part to what I need, but not the exact one. The 118-PDB241-E420K-504B0-ND has a “knurled” shaft for the dial to mount to but the pot I am replacing has a “flattened” shaft. This would make the third section of the part number “E420F.” I don’t see that variety in inventory and it doesn’t come up when I use the substitute search.

Am I missing something, or would this be a special order? I’m half-tempted to just Dremel off part of the knurled shaft and call it good.

Thanks for any assistance,

Marc

Hello @commerce
If I search using the parametric filter what I come up with unfortunately was a non-stocking part with a minimum order requirement.

Part number P230-2FC20BR500K-ND
This has 500K ohm 1/2W Flatted actuator 1/4"

If you are flexible with wattage here is a 1/4W option. Part number 450D504-6-ND

This might indeed work, thank you! Hopefully there’s 500M version too.

I really appreciate your digging around for this, thanks again.

500, not 500M. Found it. :slight_smile:
