What are the key features of TSM-136-04-SS-DH-A-K-TR?
- 72-position dual-row configuration on 0.100" (2.54 mm) pitch for maximum I/O density
- Straight surface mount (SS) tails for standard SMT reflow solder processes
- Keyed (K) and alignment-post (A) design prevents reverse or misaligned mating
- Gold-plated contacts providing low contact resistance and corrosion immunity
- Tape-and-reel (TR) delivery for automated pick-and-place high-volume assembly
What is TSM-136-04-SS-DH-A-K-TR used for?
The TSM-136-04-SS-DH-A-K-TR is used in high-I/O backplane systems, FPGA daughter cards, and multi-module industrial control platforms where 72 signal or mixed-power contacts must be routed in a compact SMT footprint. It is well-suited for applications requiring polarized mating and repeatable automated assembly in telecom, defense electronics, and embedded computing.

Frequently Asked Questions
With 72 positions in a dual-row layout, how does TSM-136-04-SS-DH-A-K-TR fit onto standard 0.100" PCB grid designs?
The TSM-136-04-SS-DH-A-K-TR uses a 0.100" (2.54 mm) pitch dual-row footprint that aligns directly with industry-standard PCB grid patterns. Its 72 pins span 36 columns, allowing straightforward layout in EDA tools on any standard 100 mil grid.
Can the alignment post on TSM-136-04-SS-DH-A-K-TR improve solder paste registration on high-density boards?
Yes. The -A alignment post anchors the connector body during placement and reflow, keeping the 72-pin SMT strip accurately positioned over the land pattern and preventing movement that could cause solder bridges or misaligned joints on high-density PCBs.
What lifecycle and procurement considerations apply when sourcing TSM-136-04-SS-DH-A-K-TR in large volumes?
Samtec's TSM series is an active product line with typical factory lead times of 2–3 weeks for standard orders and tape-and-reel (TR) packaging available for reel quantities of 500 or 1000 pieces, making it suitable for long-term program sourcing on industrial and defense platforms.
How does the 72-position TSM-136-04-SS-DH-A-K-TR compare to the 66-position TSM-133 variant for FPGA mezzanine designs?
The TSM-136 adds 6 more positions (72 vs. 66 pins) in the same 0.100" pitch dual-row format. For FPGA mezzanines needing additional GPIO or power pins beyond what 66 positions allow, the TSM-136 provides those extra 6 contacts without changing the connector family or PCB footprint style.
