Part number data

I need a relay- G6A-474P. I found one with P-ST20-US-24V. What do the ST20-US mean?

Hi,
Welcome to the Digikey tech forum. Looks like the relay you have is from an Omron series that is now obsolete, Relays | Signal Relays, Up to 2 Amps | DigiKey. Do you have more markings on the relay to provide, what is the coil voltage ?

All I want to know is what does the ST-20-US means. 24vdc

Please use this part number breakdown as a guide.

Those suffix’s should call out–
ST = Stand-off 0.64 mm
20 = 200 mW
US = UL/ CSA Approved

Thanks, Don’t understand what Stand-off is but don’t think it matters?

The 0.64 is the plastic bump on the bottom of the part. For example,

Kinda what I figured. Thanks
