The keying slot prevents insertion of a mismatched plug, a common field-assembly error.
In a right-angle SMT package, these features are critical — without them the pins lift under the torque of a mated cable assembly.
Yes — the header includes both a keying slot and board lock, plus solder retention features. The keying slot prevents mating with an incorrect receptacle, and the board lock anchors the part during reflow and resists vibration.
The listed applications include Automotive, General Purpose, Medical, and Telecommunications. The 3 A rating and -65°C to 105°C range suit non-sealed cabin-level automotive signal circuits, but it is not a sealed (IP-rated) connector.
No — the 147278-3 is listed as RoHS non-compliant. The contact finish on the post includes tin-lead, which triggers the exemption expiry. Verify your assembly's RoHS requirement before committing the BOM line.
