Board Fit and Routing
The 0717640120: Because it is a breakaway design, the header can be snapped to a shorter length if the BOM calls for fewer than 20 positions, though the factory ships it fully populated (all positions loaded).
Contact Plating and Cycle Life
The mating surface carries 15.0 µinch (0.38 µm) gold over the copper alloy base, with a tin post finish for the solder tails. Gold at this thickness supports several hundred mating cycles — adequate for field-service equipment where the connector is mated and unmated during maintenance, but not for daily hot-swap duty.
Compliance and Application Range
The connector is listed for automotive, general purpose, lighting, medical, and telecommunications applications — a broad qualification that covers most commercial and industrial environments. The base product number is 071764; the full 0717640120 suffix defines the 20-position, right-angle, gold-plated variant.
