What are the key features of TSM-116-03-T-DH-P-TR?
- 32-position dual-row 2.54 mm pitch layout with polarization (P) key prevents reverse-insertion errors in field-assembled or production stacked-board systems
- Phosphor bronze contacts with matte tin-over-nickel (50 µin Ni barrier) finish deliver 3 A per pin at 250 V with robust corrosion resistance for long-term reliability
- Tape-and-reel (TR) packaging supports high-volume automated SMT pick-and-place assembly at standard 260°C peak reflow temperatures
What is TSM-116-03-T-DH-P-TR used for?
The TSM-116-03-T-DH-P-TR is designed for backplane connectors, industrial control boards, and embedded computing motherboards where 32 signals must interface with a removable daughtercard and polarized mating is required to prevent incorrect board insertion. The 2.54 mm pitch format is broadly compatible with prototyping headers and standardized expansion interfaces used in programmable logic controllers and data-acquisition systems. Tape-and-reel packaging makes it suitable for high-throughput SMT production lines processing thousands of boards per shift.

Frequently Asked Questions
How does the polarization key (P suffix) on TSM-116-03-T-DH-P-TR protect against mis-mating in production assemblies?
The P-suffix polarization key is a mechanical protrusion in the 2.54 mm pitch housing that blocks 180° reversed insertion of the mating SFM socket; this prevents reversed-polarity events across all 32 contacts, each rated at 3 A and 250 V, eliminating potential board damage worth hundreds of dollars per incident in production or field-service scenarios.
What contact material and finish does TSM-116-03-T-DH-P-TR use, and how does it affect soldering and long-term reliability?
Contacts are phosphor bronze with matte tin-over-nickel plating, where the 50 µin nickel barrier prevents tin migration into the base alloy; this combination maintains solder wettability during 260°C peak reflow, keeps contact resistance below 30 mΩ over 100+ mating cycles, and resists oxidation in industrial environments up to 85°C and 85% relative humidity.
For a 32-signal industrial I/O board, when would a designer choose TSM-116-03-T-DH-P-TR over a gold-plated SAMTEC alternative?
Tin-over-nickel contacts in TSM-116-03-T-DH-P-TR are a cost-effective choice when mating cycles remain below 100 and operating temperatures stay under 70°C; gold-plated variants are preferred only when contact resistance below 10 mΩ is required after 200+ cycles or when the 32-pin interface operates in corrosive industrial atmospheres, saving roughly 20-30% in connector cost per board with tin finish.
