Engineering Selection Recommendations

The NMK1205SC is obsolete; the MEJ2D1205SC is active and compliant with ROHS3 and REACH regulations. Both parts satisfy inventory and compliance requirements. Substitution is permitted when all listed parameters (output, input range, output voltage/current, total power, isolation voltage, operating temperature, mounting, package, and certifications) are met as shown.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for substituting NMK1205SC?
A1: The critical parameters are number of outputs, input voltage range, output voltages and currents, total power, isolation voltage, operating temperature, mounting type, package style, size, and RoHS/REACH compliance.

Q2: Is the MEJ2D1205SC footprint compatible with the NMK1205SC?
A2: Both use a 7-SIP Module, 5 Leads package and are through-hole, but physical size differs slightly. Mechanical compatibility should be verified based strictly on provided package dimensions.

Q3: Does the MEJ2D1205SC meet the same operating temperature and application standards?
A3: Yes. Both devices support -40°C to 85°C and are specified for ITE (Commercial) applications.

Q4: Are there isolation voltage differences that should be considered?
A4: Yes. NMK1205SC offers 3 kV, while MEJ2D1205SC offers 5.2 kV. The substitute part provides a higher isolation rating.

Q5: Does compliance status affect substitutability?
A5: Both parts are ROHS3 compliant and REACH unaffected. Compliance status is suitable for substitution based on the provided data.
