What are the key features of TSM-136-03-SS-DH-A-P-TR?
- 72-position dual-row configuration at 2.54 mm (0.100") pitch provides high-density polarized signal routing on a single SMT connector footprint
- Short-solder tail contact design reduces solder bridging risk and optimizes solder joint formation in automated reflow assembly
- Polarized housing prevents incorrect connector orientation, eliminating costly assembly errors in 72-pin dual-row configurations
- Tape-and-reel packaging ensures consistent component orientation for high-speed automated pick-and-place SMT production
What is TSM-136-03-SS-DH-A-P-TR used for?
The TSM-136-03-SS-DH-A-P-TR is used in high-density board-to-board interconnect designs for industrial backplanes, embedded processor expansion cards, and multi-function I/O modules requiring 72 polarized signal channels at 2.54 mm pitch. Its short-solder tail and polarized housing combination supports reliable automated assembly in high-volume production of industrial PLCs, motion controller interface boards, and rugged embedded computing platforms. Engineers deploy this connector where large pin counts and mis-mating prevention are simultaneously required in SMT assemblies.

Frequently Asked Questions
What pin count and pitch does the TSM-136-03-SS-DH-A-P-TR offer, and how does polarization benefit 72-pin assemblies?
The TSM-136-03-SS-DH-A-P-TR provides 72 positions in a dual-row layout at 2.54 mm (0.100 inch) pitch. The polarized housing ensures the connector can only mate in the correct orientation, preventing accidental reversal of all 72 signals — a critical safety feature when power and data lines share the same connector body.
How does the short-solder tail design of the TSM-136-03-SS-DH-A-P-TR affect solder joint quality during reflow assembly?
Short solder tails reduce the solder volume required per contact and minimize the risk of solder bridging between adjacent 2.54 mm pitch pads during reflow. This results in more consistent solder joints across all 72 positions, lowering defect rates in automated SMT lines processing boards at standard lead-free reflow peak temperatures of 260°C.
For a 72-channel industrial PLC expansion card, when would the TSM-136-03-SS-DH-A-P-TR be preferred over two separate 36-position connectors?
A single 72-position connector reduces the PCB footprint by eliminating the gap between two 36-position units and removing one mating action during field assembly. It also simplifies cable management and ensures all 72 signals remain mechanically linked, preventing partial disconnection scenarios where one of two connectors loosens due to vibration exposure at 5 G to 10 G levels.
What minimum production volume justifies ordering the TSM-136-03-SS-DH-A-P-TR in tape-and-reel packaging versus cut tape?
Tape-and-reel packaging becomes cost-effective at production volumes above approximately 500 units per run, where automated pick-and-place equipment at 2.54 mm pitch placement accuracy eliminates manual loading steps. Below that threshold, cut tape packaging avoids minimum reel quantity commitments of typically 500 to 2000 pieces per full reel for this connector family.
