Frequently Asked Questions (FAQ)

Q: Can M80-8401745 be used as a direct replacement for B5741-117-F-N-2 in existing assemblies?

A: Yes. Both connectors share identical mating pitch (0.079"), 17-position configuration, female socket contact type, through-hole solder termination, and locking ramp fastening. Mechanical and electrical compatibility is maintained for standard applications operating within 120V specifications.

Q: What is the primary advantage of switching to M80-8401745?

A: M80-8401745 is in active production status, eliminating obsolescence risk. Additionally, it provides ROHS3 compliance and an 800V voltage rating, offering regulatory alignment and enhanced electrical performance for future-proofing designs.

Q: Are there differences in contact post length between these connectors?

A: Yes. B5741-117-F-N-2 features a 0.051" (1.30mm) contact post length, while M80-8401745 has a 0.126" (3.20mm) contact post length. This difference may affect mating height and stacking configurations in specific applications.

Q: What is the difference in insulation material composition?

A: B5741-117-F-N-2 uses polyester glass-filled insulation, while M80-8401745 uses polyamide (PA46) nylon 4/6 glass-filled insulation. Both materials maintain UL94 V-0 flammability ratings and identical operating temperature ranges.

Q: Are packaging considerations important for procurement?

A: M80-8401745 is supplied in tube packaging, while B5741-117-F-N-2 packaging is unspecified. Verify packaging requirements for your assembly process and inventory management systems.

Q: Does the higher voltage rating of M80-8401745 affect compatibility?

A: No. The 800V rating of M80-8401745 is a performance enhancement that does not compromise compatibility with applications designed for 120V operation. The connector remains suitable for all voltage levels up to its rated maximum.
