14 Circuits at 1.25 mm Pitch — What That Means for Board Fit
The 0530471460: This is a 14-position, single-row vertical header from the PicoBlade 53047 series. The 1.25 mm pitch sets a tight board footprint — routing a 14-wide trace bundle on a single layer is possible if the trace width and clearance fit within 0.5 mm per channel.
Gold Flash vs. Thicker Gold — Mating Cycle Reality
For a connector that stays mated for the product life (e.g., internal PSU-to-control board), flash gold is adequate. If this header sees quarterly field disconnects, budget for contact fretting after ~30 cycles. The post finish is 39.4 µinch tin — that's the solder-joint side, not the mating interface.
Detent Lock — No Secondary TPA
The fastening is a detent lock — it clicks when fully mated and holds against moderate vibration. There is no terminal position assurance (TPA) feature on this header. In a harness that sees repeated flex or high-g shock (e.g., portable medical equipment), the terminals can back out of the receptacle housing if the crimp is not fully seated. The PicoBlade receptacle (53261 series) does include a TPA, but the header side relies solely on the detent.
Current Rating — Wire-Gauge Dependent
For a 14-circuit bundle, derate for mutual heating: at 1 A per circuit, the total bundle current is 14 A, but the temperature rise in the center of the connector may exceed the 85 °C operating limit if ambient is above 60 °C.
