Current rating and operating range
Peer comparison — 1379030-3 vs 5-146254-8
The 5-146254-8 is unshrouded, vertical, and has 16 positions — it's a different mechanical fit for applications that don't need the locking flange or the right-angle board exit. Both use tin-plated contacts at 2.54mm pitch, but the 1379030-3 is rated for 12 V and targets wire-to-board applications, while the 5-146254-8 is a general-purpose board-to-board or cable-to-board breakaway header.
