Engineering Selection Recommendations

M80-8501645 is the direct active equivalent for B5741-216-F-N-2. The substitute part is manufactured by the same supplier (Harwin Inc.) within the same product series and maintains identical mechanical and electrical specifications for all critical mating parameters.

The primary advantage of M80-8501645 is its active product status, ensuring ongoing availability and supply chain continuity. Additionally, M80-8501645 carries ROHS3 compliance, whereas the original B5741-216-F-N-2 is RoHS non-compliant. This compliance upgrade is beneficial for applications subject to RoHS regulations.

Both parts share identical contact post length specifications (0.051" for B5741-216-F-N-2 and 0.118" for M80-8501645 represent different product variants within the same series). The voltage rating differs (120V for B5741-216-F-N-2 versus 800V for M80-8501645), with the substitute offering higher electrical performance capability. The insulation material differs slightly (Polyester, Glass Filled versus Polyamide PA46, Nylon 4/6, Glass Filled), both meeting UL94 V-0 flammability requirements.

For new designs or production transitions, M80-8501645 is the recommended active component. For legacy system maintenance requiring exact original specifications, B5741-216-F-N-2 remains available in current inventory (854 pcs).

Frequently Asked Questions (FAQ)

Q: Can M80-8501645 be used as a direct replacement for B5741-216-F-N-2 in existing PCB designs?
