Frequently Asked Questions
How many positions does TSM-128-03-FM-DH-A-P-TR accommodate and what is the row configuration?
TSM-128-03-FM-DH-A-P-TR accommodates 56 positions arranged in a dual-row layout on a 0.100" (2.54 mm) pitch, allowing 56 signal pins to be routed through a single SMT footprint in backplane or daughter-card designs.
For a compact industrial controller design, can TSM-128-03-FM-DH-A-P-TR be soldered using a standard SMT reflow process?
Yes. TSM-128-03-FM-DH-A-P-TR uses surface mount termination compatible with standard reflow profiles up to 260°C, and its tape and reel packaging ensures the 56-position connector can be placed automatically without manual handling.
What contact finish does TSM-128-03-FM-DH-A-P-TR use and how does it perform after multiple mating cycles?
All 56 mating contacts are gold-plated over a nickel barrier, delivering stable low contact resistance and corrosion resistance through hundreds of connection cycles, which is essential for removable daughter cards in test fixtures and modular industrial systems.
Is there a lower pin-count TSM alternative to TSM-128-03-FM-DH-A-P-TR for designs that only need 10 to 20 pins?
Yes. SAMTEC's TSM series spans from 10 to 100+ positions on the same 0.100" dual-row pitch, so TSM-105 (10-position) or TSM-110 (20-position) variants offer the same gold contact finish and tape-and-reel supply format when fewer than 56 pins are required.
