The closest functional alternative is 1376779-2, also a 12-position AMPMODU Mod II header with gold mating finish, but the gold thickness is 8.00 µinch — roughly half the mating cycle life of the 15.0 µinch on 9-146276-0-12. If your application sees frequent disconnect/reconnect, the thicker plating buys you margin.

Frequently asked questions
What mates with this 12-pin breakaway header?
The unshrouded header requires the mating half to have its own alignment features — it does not provide shroud protection against misalignment.
Can 9-146276-0-12 be used for wire-to-board connections?
Yes, the connector style is listed as Board to Board or Cable. The unshrouded male pins accept crimp socket housings from the AMPMODU Mod II family, making it suitable for wire-to-board harnesses.
Where can I buy 9-146276-0-12?
This part is sourced per RFQ through independent distribution.
