Frequently Asked Questions
How many contacts does TSM-121-04-S-DH-P-TR have, and how does the quad-row layout optimize PCB density?
TSM-121-04-S-DH-P-TR provides 42 contacts arranged in a quad-row format with 0.100" (2.54 mm) pitch. The quad-row configuration allows 42 signals to be routed through a shorter connector body length compared to single- or dual-row alternatives, reducing the linear PCB space consumed while maintaining standard 2.54 mm through-pitch compatibility.
Which mezzanine or stacking applications is TSM-121-04-S-DH-P-TR designed to support?
The DH (dual-height) suffix indicates a taller housing profile that provides clearance between stacked PCBs, accommodating passive components or routing layers beneath the connector in mezzanine assemblies. TSM-121-04-S-DH-P-TR is appropriate for board-stacking designs in embedded SBCs, industrial expansion modules, or modular instrument cards that require 42-pin connectivity with defined inter-board spacing.
How does the polarization feature of TSM-121-04-S-DH-P-TR reduce assembly risk in quad-row connector configurations?
The P (polarized) suffix adds a physical keying feature to the 42-position quad-row housing, ensuring that the mating connector can only be inserted in the correct orientation. In complex PCB assemblies with multiple similar connectors in close proximity, this prevents misalignment errors during automated SMT placement or manual field assembly, reducing rework and potential board damage.
What volume procurement and packaging details are available for TSM-121-04-S-DH-P-TR?
TSM-121-04-S-DH-P-TR is packaged in tape-and-reel (TR) format, enabling direct use in automated pick-and-place SMT assembly lines without manual handling. SAMTEC supports this connector family through its global authorized distribution network; buyers should confirm reel quantities and lead times with their preferred distributor when planning production volumes for 42-position quad-row SMT connector requirements.
