Key Features
- 62-position triple-row configuration at 2.54 mm (0.100 inch) pitch with approximately 20-21 contacts per row, maximizing signal density in constrained PCB areas compared to dual-row alternatives
- Low-profile (LM) mounting height reduces connector profile above the PCB surface, enabling tighter board-to-board spacing in stacked module designs
- Tape-and-reel (TR) packaging with polarized (P) shrouded dual-row housing for mis-mate prevention and seamless integration into automated high-volume SMT pick-and-place production lines
Applications
The SAMTEC TSM-131-03-LM-DH-A-P-TR is used in FPGA prototyping boards, embedded computing modules, and industrial I/O expansion cards where 62 signals must be routed through a compact 2.54 mm pitch surface-mount connector. Its triple-row layout reduces the connector footprint length compared to a single- or dual-row equivalent, freeing PCB space for other components. The polarized shroud guides cable assemblies into correct mating position, preventing signal errors during system assembly and maintenance.

Frequently Asked Questions
How many rows and positions does the TSM-131-03-LM-DH-A-P-TR provide at 2.54 mm pitch?
The TSM-131-03-LM-DH-A-P-TR provides 62 positions across 3 rows at a 2.54 mm (0.100 inch) pitch. The triple-row arrangement places approximately 20 or 21 contacts per row, compressing a large contact count into a shorter connector body length compared to dual-row versions handling the same 62 signals.
What does the low-profile (LM) designator mean for stacked PCB module designs using the TSM-131-03-LM-DH-A-P-TR?
The LM (low-mount or low-profile) variant reduces the connector height above the PCB surface compared to standard TSM mounting options. In stacked module designs with board-to-board clearances less than 8 mm, a lower profile connector at the 2.54 mm pitch allows tighter stacking, which is valuable in compact embedded computing form factors and multi-layer FPGA carrier boards.
Is the TSM-131-03-LM-DH-A-P-TR backward compatible with standard 2.54 mm pitch dual-row cable assemblies?
The TSM-131-03-LM-DH-A-P-TR is a triple-row connector, so it is not directly interchangeable with dual-row cable assemblies. It requires a matching triple-row mating connector or cable assembly at the 2.54 mm pitch. SAMTEC offers compatible triple-row cable socket assemblies in pre-terminated configurations up to 500 mm length for the 62-position interface.
For high-volume production, how does tape-and-reel packaging help when assembling the TSM-131-03-LM-DH-A-P-TR?
The -TR tape-and-reel packaging presents each connector in a standardized carrier tape compatible with SMT pick-and-place machines feeding components from reels. This eliminates manual placement of the 62-position part, reducing placement error rates and supporting assembly throughput rates of hundreds of units per hour when using automated SMT production lines operating at 260 °C peak reflow temperature.
