4-102973-0-05

The 4-102973-0-05 is a 10-position, 2-row unshrouded header manufactured by TE Connectivity. It features a 2.54mm (0.100 inch) pitch, making it suitable for standard board-to-board or cable connections. The header uses through-hole mounting with solder termination, providing a secure mechanical and electrical connection. The contacts are made of copper alloy with a square pin shape and a tin-lead finish (15.0 µin thickness). The insulator is black thermoplastic with a UL94 V-0 flammability rating, ensuring flame retardancy.

Electrically, the header is rated for 3A continuous current. The operating temperature range is -65°C to 105°C, allowing use in a wide variety of environments. The overall contact length is 0.533 inches (13.55mm), with a mating pin length of 3.18mm. The header is unshrouded with a push-pull fastening type, and all 10 positions are loaded. The row spacing is 2.54mm, consistent with the pitch.

This header is suitable for prototyping, industrial control, and consumer electronics applications where a reliable, low-cost interconnect is needed. The breakaway design allows the header to be cut to size if fewer positions are required, though this part comes pre-configured with 10 positions.
