Frequently Asked Questions
What does the -K suffix on TSM-129-04-S-DH-A-K-TR indicate and why is it important for system assembly?
The -K suffix designates a keying feature that physically prevents incorrect mating orientation of the 58-position dual-row 0.100 inch pitch connector. This is especially important in industrial and telecom equipment where misaligned insertion during field service or initial board assembly could damage 58 signal pins or cause system faults, making the keyed version safer for high-pin-count applications.
How are the 58 positions distributed across the dual rows of TSM-129-04-S-DH-A-K-TR?
The TSM-129-04-S-DH-A-K-TR arranges 58 positions in a dual-row layout at 0.100 inch (2.54mm) pitch, placing 29 pins per row. This configuration allows designers to allocate signal, power, and ground connections across two rows in a compact SMT footprint, which is useful for industrial I/O boards and backplane interconnects requiring many parallel signal paths.
For a high-volume PCB production line, does TSM-129-04-S-DH-A-K-TR support automated pick-and-place assembly?
Yes. The -TR suffix indicates tape-and-reel packaging, which is fully compatible with standard automated SMT pick-and-place equipment. The 58-position connector can be accurately placed on the 0.100 inch pitch dual-row footprint during reflow soldering, reducing manual handling and ensuring consistent placement quality in high-volume telecom and industrial board production.
What procurement risk should buyers consider when sourcing TSM-129-04-S-DH-A-K-TR for ongoing production?
The TSM-129-04-S-DH-A-K-TR is a specialized 58-position keyed SMT connector with options (-A, -K suffixes) that may have longer lead times or lower distributor stock depth than standard configurations. Buyers should confirm availability with SAMTEC or authorized distributors at least 8 to 12 weeks in advance and evaluate approved alternate sourcing for the 0.100 inch pitch 58-position dual-row footprint to mitigate supply chain risk.
