What are the key features of TSM-121-04-SS-DH-P-TR?

42-position dual-row surface mount terminal strip at 0.100 inch (2.54 mm) pitch
Stainless steel (SS) contact plating for enhanced corrosion resistance in harsh environments
Dual-height polarized (DH-P) housing prevents incorrect mating across 42 signal positions
Tape-and-reel (-TR) packaging enables high-throughput automated pick-and-place SMT assembly
Standard 0.100 inch pitch footprint compatible with broad 2.54 mm connector ecosystem

What is TSM-121-04-SS-DH-P-TR used for?

The TSM-121-04-SS-DH-P-TR is designed for high-density board-to-board and wire-to-board interconnect in industrial automation, rugged embedded computing, and outdoor telecommunications equipment where stainless steel contact plating provides corrosion resistance in humid or chemically challenging environments. The polarized dual-height housing and tape-and-reel packaging make it suitable for high-volume automated SMT assembly on boards requiring 42-position signal routing.

Frequently Asked Questions

During footprint review, what contact spacing must engineers preserve for TSM-121-04-SS-DH-P-TR?

TSM-121-04-SS-DH-P-TR uses 2.54 mm contact spacing, so the PCB land pattern and mating component must preserve that pitch across every position during layout verification.

Where would designers typically use this terminal strip within an electronic assembly?

This terminal strip uses a 2.54 mm interface suited to compact board interconnects; engineers should also confirm stack height, termination, polarization, and rated mating cycles.

How can a buyer reduce alternate-part risk when sourcing TSM-121-04-SS-DH-P-TR?

Procurement should match the exact 2.54 mm pitch, row arrangement, termination style, polarization, contact finish, and packaging code against the released manufacturer drawing.
