The 9-146256-0-05: The unshrouded push-pull design mates with any AMPMODU Mod II receptacle housing or IDC socket that accepts a 0.025" (0.64mm) square pin on 2.54mm pitch. The 10-position dual-row layout matches the standard 2x5 receptacle footprint. No secondary lock — the retention relies on the contact normal force and the push-pull interface.
Temperature and flame rating
This covers most indoor and outdoor equipment enclosures where the board sits inside a protected cabinet — the housing will not sustain flame if a fault occurs.
How it compares to 1376779-2
The closest functional sibling is 1376779-2 — same 10-position dual-row layout, same 2.54mm pitch, same gold-over-nickel mating finish. For applications that see fewer than 50 mating cycles over the product life, the thinner gold saves cost without risking contact wear-through.
