Frequently Asked Questions
What is the pin count and pitch of the TSM-121-04-T-DH-P-TR?
The SAMTEC TSM-121-04-T-DH-P-TR is a 42-position surface-mount terminal strip with a 0.100" (2.54 mm) pitch in a dual-row (DH) configuration, providing a standard footprint widely used in industrial, test, and embedded computing PCB designs.
Does TSM-121-04-T-DH-P-TR support high-volume automated SMT assembly?
Yes. The TSM-121-04-T-DH-P-TR is supplied in tape-and-reel (TR) format, making it directly compatible with automated pick-and-place machines for high-volume SMT production. Its surface-mount termination supports standard lead-free reflow soldering at peak temperatures of 260°C.
Which board-level interconnect applications benefit most from the 42-position dual-row layout of TSM-121-04-T-DH-P-TR?
With 42 pins in a dual-row 0.100" pitch layout, the TSM-121-04-T-DH-P-TR is well suited for daughtercard-to-motherboard interfaces, backplane signal distribution, and PCB-to-cable headers in industrial controls and test equipment where a large number of signal lines must be routed in a compact, standardized footprint.
How does TSM-121-04-T-DH-P-TR compare to single-row SAMTEC terminal strips in terms of signal density?
The dual-row (DH) design of TSM-121-04-T-DH-P-TR provides 42 contacts in roughly the PCB footprint a single-row 21-pin strip would occupy at 0.100" pitch, effectively doubling signal density. This makes it preferable in space-constrained designs requiring more than 20 connections at the standard 2.54 mm grid.
