The 0.100-inch (2.54 mm) pitch matches the industry-standard footprint for IDC sockets and crimp receptacles — no board respin needed if you are replacing a legacy 0.100-inch header. The tin-plated post (100.0 µinch) is compatible with standard wave-solder processes.
Unshrouded Push-Pull Mating
The 0.318-inch (8.08 mm) mating length gives good wipe before the contact bottoms out, which helps with contact resistance stability in moderate-vibration environments.
How This Compares to Peer Headers
That part trades position count and plating for a locking mechanism and board lock feature — use it when vibration demands a positive latch. The 953440-3 is a 6-position automotive-grade header with a friction lock and 12 V rating, but its UL94 HB housing and tin contacts limit it to lower-reliability environments. For a general-purpose 10-position unshrouded header with gold contacts, this 9-146253-0-05 is the straightforward choice.
