Applications
The TSM-136-01-TM-DH-A-K-TR is suited for high-I/O embedded computing modules, FPGA mezzanine boards, and industrial backplanes that require 72 polarized SMT contacts with reliable reflow solder attachment. Its keying and alignment features are especially valued in automated assembly environments where mis-mating of 72-pin connectors could cause board damage or functional failures.

Frequently Asked Questions
What differentiates the tail-mount (TM) termination on TSM-136-01-TM-DH-A-K-TR from standard straight-surface-mount tails?
Tail-mount (TM) termination forms the contact tail at a specific angle or offset to improve solder joint geometry on the PCB land pattern. For a 72-pin dual-row 0.100" strip, this can improve co-planarity across the full connector length, reducing solder joint opens during reflow compared to straight-tail variants.
How does the keying feature on TSM-136-01-TM-DH-A-K-TR protect a 72-pin backplane from mis-mating during field installation?
The -K keying notch on the connector body physically prevents insertion of non-keyed or misoriented mating connectors. On a 72-position backplane with multiple identical-looking connectors, keying ensures that only the correct mating half can be inserted, preventing signal mapping errors that could damage high-value PCB assemblies.
For an FPGA mezzanine card needing over 64 I/O signals, is TSM-136-01-TM-DH-A-K-TR a practical single-connector solution?
Yes. With 72 positions in a dual-row 0.100" pitch layout, TSM-136-01-TM-DH-A-K-TR can carry 72 independent signal or mixed-voltage contacts, covering FPGA GPIO banks, power, and ground in a single connector. This eliminates the need for multiple smaller connectors and simplifies PCB routing on mezzanine designs.
What RoHS and lead-free status should buyers verify when ordering TSM-136-01-TM-DH-A-K-TR for EU-compliant products?
Samtec's TSM series is offered in Pb-free termination finishes compatible with RoHS Directive 2011/65/EU. Buyers ordering for EU-compliant products should confirm the JESD-609 'e3' or equivalent code on the purchase documentation, ensuring the 72-pin connector's solder tails meet lead-free solder process requirements at standard reflow temperatures.
