3.5 mm mono jack specs

[Rich Cohen]

I need to find a 3.5 mm mono jack that is slightly longer than the standard ones you see for sale on the internet. Apparently there are designated as 003 and 004, the latter being slightly longer than the 003. Can anyone enlighten me?
Thanks,
Rich Cohen

I’d guess that if Amphenol doesn’t make it it’s probably a weird one-off or ancient non-standard thing.
