Frequently Asked Questions (FAQ)

Q: Can SFMC-116-02-S-D be used as a direct replacement for SFMC-116-L2-S-D?

A: Yes. Both parts are 32-position receptacle connectors with identical pitch (0.050"), row spacing (0.050"), mounting type (surface mount), current rating (2.9A per contact), operating temperature range (-55°C ~ 125°C), and contact finish specifications. All mechanical and electrical parameters are equivalent.

Q: Are there any differences in PCB footprint between these parts?

A: No differences are specified in the provided parameters. Both parts share the same base product number (SFMC-116), connector type, position count, pitch, and row spacing, indicating identical PCB footprint requirements.

Q: What is the significance of the part number suffix difference (L2 vs. 02)?

A: The suffix variation within the SFMC-116 series indicates different internal configurations or manufacturing variants. However, the provided electrical and mechanical parameters are identical, confirming functional equivalence for connector interface applications.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet UL94 V-0 flammability requirements and ROHS3 compliance. Both operate across the -55°C ~ 125°C temperature range with 2.9A per contact current rating. Selection should be based on specific application requirements and environmental conditions.

Q: What is the moisture sensitivity classification for these connectors?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Standard handling and storage practices are sufficient; no special dry-pack or bake-out procedures are required.
