10-position SMT header with latch lock for board-to-board or cable
The 1-338728-0: This is a 10-position, dual-row SMT header from TE's Micro-MaTch series, pitched at 2.54mm (0.100") — a standard spacing for prototyping and low-density interconnects. The shrouded 4-wall design with latch lock keeps the mating half secure under vibration, and the tin-plated contacts (3.00µm on the mating side) are rated for 1.5A per circuit at 230V. The red PA46 glass-filled insulator carries UL94 V-0 flammability rating and handles -40°C to 105°C, making it suitable for industrial control cabinets and general-purpose equipment that sees moderate thermal cycling.
SMT footprint and latch lock — fit considerations
The 2.54mm pitch and SMT termination match standard board layouts for prototyping or low-volume production. The latch lock adds a positive retention feature that non-locking headers lack — critical if the cable or board mate sees vibration or accidental tugging. This SMT version saves board space on the opposite side compared to a through-hole variant and is suited for double-sided assemblies.
