I'm inquiring about the compatibility of the parts

Interconnect Circular Connectors

I would like to ask if I can use MS3102A-24-7P instead of MS3102E-24-7P

Is it compatible except for waterproof performance?

Hello,

Welcome to the TechForum.

From what i see of the part number break down this looks to be a good alternate. This is the callouts from the datasheet for the letter difference:
3. Service Class
A solid shell for general, non-environmental applications
C solid shell for pressurized applications
E environmental resisting
F environmental resisting with strain relief (MS part num
ber only)
R lightweight environmental resisting

Thank you
Ryan
