Panasonic Relay Marking

[chick0n]

Hi

Im wondering about Panasonic / Nais brand Relay markings.

For example, there are RF-Relais marked:
RK1-L2-5V, but some are marked  RK1-L2-5V-H51, or  RK1-L2-5V-H23.

What does the "H" marking mean? I couldnt find any information in the datasheets.

I also found this on other series from panasonic: JJM2W-12V, JJM2W-12V-H52...

I found this:

"the Hxx suffixes are custom parts and the part numbering is not standardized. This can be a simple as a custom part marking and can be more complicated with plated up/down version or high temp epoxy. It is possible that the standard part will work, however if for example it is a high temp epoxy the replacement part may not be suitable for the application."
