Parameter Comparison

Engineering Selection Recommendations

The Molex 0386907602 serves as a direct functional substitute for the obsolete 0386906402. Both components share identical circuit count, pitch spacing, voltage rating, temperature rating, and flammability compliance. The substitute part offers a higher current rating of 20A compared to the original 15A specification, providing enhanced capacity for the same footprint and mounting configuration.

The 0386907602 maintains ROHS3 compliance and active product status, ensuring long-term availability and supply chain continuity. The addition of a captive plate on the screw termination in the substitute part provides improved mechanical retention without affecting electrical or thermal performance.

For applications currently using the 0386906402, the 0386907602 can be directly substituted without PCB layout modifications or connector interface changes.

Frequently Asked Questions (FAQ)

Q: Can the 0386907602 be used as a direct replacement for the 0386906402 on existing PCBs?

A: Yes. Both parts share identical pitch spacing (0.325"), circuit count (2), mounting type (through-hole), and PC pin configuration. No PCB layout modifications are required.

Q: What is the difference between the screw termination types?

A: The 0386906402 features standard screws, while the 0386907602 includes a captive plate design. The captive plate prevents screw loss during assembly and maintenance. Both provide equivalent electrical performance.

Q: Is the higher current rating of the 0386907602 a concern for existing designs?

A: No. The 20A rating of the substitute part exceeds the original 15A specification, providing additional capacity margin. Existing designs operating within 15A limits will function identically.

Q: Are both parts RoHS compliant?

A: Yes. Both the 0386906402 and 0386907602 are ROHS3 compliant.

Q: What is the packaging difference between these parts?

A: The 0386906402 is supplied without specified packaging, while the 0386907602 is packaged in trays. This does not affect component functionality or performance.
