Frequently Asked Questions
What is the contact count and configuration of the TSM-131-03-STL-SH-A?
The TSM-131-03-STL-SH-A is a dual-row connector with 31 pins per row, giving 62 total contacts on a 2.54 mm (0.100 inch) pitch. The shrouded housing polarizes mating to protect against reverse insertion and mechanical damage during assembly.
Which PCB assembly environments are best served by the TSM-131-03-STL-SH-A horizontal surface mount design?
The horizontal surface mount termination style makes the TSM-131-03-STL-SH-A ideal for compact embedded systems, industrial control boards, and development kits where reflow soldering of 62 contacts across 31 pins per row on a standard 0.100 inch grid is preferred over through-hole assembly.
How does the TSM-131-03-STL-SH-A compare to through-hole dual-row headers for PCB fabrication complexity?
Unlike through-hole headers that require drilling 62 holes across 31 pins per row at 2.54 mm pitch, the TSM-131-03-STL-SH-A surface mount pads eliminate through-hole drilling, allow double-sided component placement, and reduce assembly cost in high-volume automated reflow production runs.
