Engineering Selection Recommendations

Both the Molex 0873814464 and 3M 150244-2020-RB are active production parts with full RoHS compliance and unlimited moisture sensitivity ratings, ensuring long-term availability and environmental regulatory adherence. The 3M substitute provides higher voltage rating capability (500VDC versus 125V) and increased gold plating thickness on mating contacts (30.0µin versus 15.0µin), offering enhanced durability in demanding electrical environments. The Molex part maintains higher current rating (1.9A versus 1A). Selection between these parts should be based on specific application voltage and current requirements. Both parts are suitable for automotive, telecommunications, and general-purpose board-to-board interconnect applications.

Frequently Asked Questions (FAQ)

Q: Can the 3M 150244-2020-RB be used as a direct replacement for the Molex 0873814464?

A: Yes.
