Key Parameters

Substitute Part Grouping Explanation

Substitution for MER1S2409SC is strictly based on matching critical electrical parameters (input voltage range, output voltage, output current, power rating), mechanical compatibility (package type, mounting, size), isolation voltage, and compliance certifications. The substitute must offer an equivalent through-hole 7-SIP package with identical dimensions, meet RoHS and REACH requirements, and operate across the same temperature range. The substitute part, MEV1S2409SC, satisfies all these conditions and is identified as an active product.

Parameter Comparison

Engineering Selection Recommendations

The MER1S2409SC is obsolete; the MEV1S2409SC is active, fully matching all specified electrical and mechanical parameters, including RoHS and REACH compliance, with identical operating temperature range, size, and mounting. MEV1S2409SC provides increased isolation voltage while maintaining all other critical specifications. Selection should be strictly based on product status and compliance reporting as listed.

Frequently Asked Questions (FAQ)

Q: What determines if MEV1S2409SC can substitute MER1S2409SC?
