15 circuits, 5.00 mm pitch, right-angle — what this header does
The 966140-2: This is a TE Connectivity MCP series header, 15 positions loaded all, arranged in 3 rows with a 5.00 mm mating pitch and 5.51 mm row spacing. Tin works well when the mated joint is not frequently cycled — expect a few hundred mate/unmate cycles before contact fretting becomes a concern. The mounting flange (Features: Mounting Flange) gives a secondary mechanical anchor to the board, resisting shear from the cable harness in vibration environments. The insulation height of 1.012" (25.70 mm) and post length of 0.118" (3.00 mm) define the board stand-off and solder tail engagement.
Where this header fits — automotive and general-purpose duty
The glass-filled PA66 (Polyamide 6/6) insulation material handles under-hood heat and industrial cabinet thermal cycling without softening. The 15-circuit count fits medium-density harness breakouts — not a high-density board edge, but a workhorse interconnect for routed cables.
Mating half and termination — what it connects to
This header mates with a corresponding MCP series receptacle housing that accepts tab contacts (Contact Type: Tab, Contact Shape: Rectangular). Termination is solder (Termination: Solder) — the through-hole posts are 0.118" (3.00 mm) long, suited for standard PCB thicknesses around 1.6 mm.
Lifecycle and sourcing — active production, no cross-reference on record
Product status is Active — no end-of-life notice, no successor announced. ROHS3 compliant. The base product number 966140 covers the family; the -2 suffix identifies this specific 15-position, right-angle, tin-plated variant. If a second source is needed, the MCP series has multiple position counts and plating options, but a direct drop-in replacement outside the series is unlikely without a board layout change.
