Key Features
- 72 positions in a dual-row 0.100" (2.54 mm) pitch configuration for high pin-count signal density
- Stand-off lead (STL) style creates clearance beneath the connector body for solder inspection and flux cleaning
- Surface mount termination supports automated SMT reflow assembly
- Tape-and-reel (TR) packaging enables high-volume automated pick-and-place manufacturing
- Gold-plated contacts provide reliable low-resistance electrical performance over extended mating cycles
Applications
TSM-136-01-STL-DH-A-K-TR is designed for high pin-count board-to-board and backplane interconnect applications in industrial automation, embedded computing, and telecommunications infrastructure. The stand-off lead style makes it especially suitable for manufacturing environments requiring post-solder flux cleaning or optical solder joint inspection beneath the 72-position connector body.

Frequently Asked Questions
How many signal positions does TSM-136-01-STL-DH-A-K-TR support and what pitch does the dual-row layout use?
TSM-136-01-STL-DH-A-K-TR supports 72 signal positions arranged in 2 rows at 0.100" (2.54 mm) pitch, with 36 contacts per row. This configuration provides high pin-count connectivity in a connector body approximately 3.6 inches long, suitable for backplane and multi-signal module applications.
Why would a PCB designer specify the STL (stand-off) lead style over a flush surface mount lead for a 72-pin connector?
The STL stand-off lead style on TSM-136-01-STL-DH-A-K-TR elevates the connector body to create a clearance gap, typically 0.030" to 0.060", beneath the housing. This space allows automated aqueous cleaning equipment or manual solvent application to reach and clean flux residue from all 72 solder joints, meeting IPC cleanliness standards for high-reliability industrial boards.
What temperature range is TSM-136-01-STL-DH-A-K-TR rated for, and does it qualify for industrial deployments?
SAMTEC TSM series connectors are rated for operation from -55°C to 125°C, confirming TSM-136-01-STL-DH-A-K-TR as suitable for industrial deployments that require robust thermal performance, including embedded computing systems in factory automation and control panels exposed to elevated ambient temperatures.
When sourcing TSM-136-01-STL-DH-A-K-TR for a new design, what procurement lead time should engineers plan for?
Lead times for TSM-136-01-STL-DH-A-K-TR in tape-and-reel format can range from a few days for stocked distributor inventory to 8 to 16 weeks for factory orders of 72-position dual-row connectors. Design teams should confirm stock levels and lead times with SAMTEC-authorized distributors early in the design cycle to avoid production delays.
