What are the key features of TSM-136-04-S-DH-A-K-TR?
- 72 positions in dual-row (DH) format at 0.100 inch (2.54 mm) pitch for very high signal count SMT interconnect
- Keyed (K) mating prevents incorrect 72-position connector orientation during assembly
- Tape-and-reel (TR) packaging with 4-position spacing variant for automated pick-and-place
- A-coded alignment ensures repeatable and secure dual-row mating engagement
- Standard 0.100 inch pitch compatible with common PCB design rule sets and footprint libraries
- Dual-row DH configuration provides 36 contacts per row in a compact SMT footprint
What is TSM-136-04-S-DH-A-K-TR used for?
The TSM-136-04-S-DH-A-K-TR is designed for very high pin count board-to-board interconnect in server backplanes, FPGA expansion daughter cards, industrial programmable controllers, and communications line cards requiring 72 signals on a 0.100 inch pitch dual-row header. Its keyed design prevents the costly assembly errors possible when populating dense multi-connector boards with multiple 72-position headers. Tape-and-reel packaging ensures it integrates seamlessly into high-volume automated SMT production lines.

Frequently Asked Questions
How many signals per row does the TSM-136-04-S-DH-A-K-TR provide, and what is its total position count?
The TSM-136-04-S-DH-A-K-TR provides 72 total positions arranged as 36 contacts per row in a dual-row DH configuration at 0.100 inch (2.54 mm) pitch, giving system designers access to 72 independent signal or power connections in a single compact SMT header.
Why is the keyed (K) option especially important on a 72-position dual-row connector like the TSM-136-04-S-DH-A-K-TR?
A 72-position dual-row connector without keying could be mated in a 180-degree reversed orientation, which would short or reverse all 72 signal and power connections simultaneously. The K keying feature physically blocks misaligned mating, protecting expensive FPGAs, processors, and power rails from reversed-connection damage during board assembly.
Which high-density PCB designs are most suited to the 0.100 inch pitch TSM-136-04-S-DH-A-K-TR?
Server backplanes carrying 72 or more parallel bus signals, FPGA daughter cards with wide data buses, industrial control systems routing analog and digital I/O together, and multi-port communications boards all benefit from the 72-position 0.100 inch pitch dual-row SMT header where standard routing grids apply.
What does the -04 suffix in TSM-136-04-S-DH-A-K-TR indicate, and does it affect mating connector selection?
The -04 suffix typically denotes a row spacing or stacking height variant in SAMTEC TSM series numbering, which affects the physical stack height between two mated boards measured in increments of approximately 0.100 inch per count. Designers must select a mating header with the matching -04 specification to ensure proper 72-position contact engagement depth.
