The keying slot prevents mating with an incorrect receptacle, and the board lock anchors the part during reflow and resists vibration."},{"question":"Can 147278-3 be used in automotive applications?","answer":"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."},{"question":"Is 147278-3 RoHS compliant?","answer":"No — the 147278-3 is listed as RoHS non-compliant. The contact finish on the post includes tin-lead, which triggers the exemption expiry.
