Frequently Asked Questions
What is the significance of the TM (tin-matte) contact finish on TSM-135-04-TM-DH-A-P-TR versus a gold-plated version?
The tin-matte finish on TSM-135-04-TM-DH-A-P-TR is RoHS-compliant and suitable for lead-free reflow soldering processes with a peak temperature of 260°C. Compared to gold-plated contacts, the tin-matte finish reduces per-unit cost while still providing adequate contact resistance for signal-level applications with moderate mating cycle requirements under 30 cycles.
How many signals can be routed through a single TSM-135-04-TM-DH-A-P-TR, and what PCB length does it occupy?
The TSM-135-04-TM-DH-A-P-TR carries 70 signals in a dual-row layout with 35 pins per row, occupying a PCB footprint length of approximately 88.9 mm on a 2.54 mm pitch. This high pin count is ideal for FPGA expansion headers and multi-channel DAQ backplanes where consolidating 70 signals into a single connector simplifies cabling and reduces assembly time.
For a procurement engineer comparing TSM-135-04-TM-DH-A-P-TR to TSM-135-03-F-DH-A-P-TR, what are the key trade-offs?
Both parts are 70-position dual-row 2.54 mm pitch SMT strips, but TSM-135-04-TM-DH-A-P-TR uses tin-matte (TM) finish for cost-effective RoHS-compliant assembly, while TSM-135-03-F-DH-A-P-TR uses gold (F) plating for lower contact resistance and more than 100 mating cycles. Choose the TM version for single-use board-to-board connections or low-cycle production connectors to reduce BOM cost.
