What are the key features of TSM-120-03-TM-DH-P-TR?
- 40-position dual-row terminal strip with 0.100" (2.54 mm) standard pitch for broad mating connector compatibility
- Top-mount (TM) orientation for vertical signal routing on the PCB surface
- Through-hole board lock pegs (P) provide mechanical retention beyond SMT solder joints
- Tape-and-reel (TR) packaging for automated pick-and-place SMT assembly lines
- Dual-row (DH) housing offers maximum contact density in a compact PCB footprint
What is TSM-120-03-TM-DH-P-TR used for?
The TSM-120-03-TM-DH-P-TR is used in industrial automation, embedded computing, and instrumentation applications requiring a 40-pin dual-row connector with added mechanical retention. The through-hole board lock pegs anchor the SMT connector to the PCB, reducing stress on solder joints in applications subject to vibration or repeated mating. Tape-and-reel packaging supports efficient integration into high-volume SMT manufacturing workflows.

Frequently Asked Questions
What pin count and pitch does TSM-120-03-TM-DH-P-TR offer for dual-row PCB connections?
The TSM-120-03-TM-DH-P-TR provides 40 contact positions arranged in a dual-row format with a 0.100 inch (2.54 mm) pitch. This is a widely used standard pitch that ensures compatibility with a broad range of mating receptacles and simplifies PCB layout with well-established 2.54 mm grid rules.
How do the through-hole board lock pegs on TSM-120-03-TM-DH-P-TR improve assembly reliability?
The through-hole board lock pegs (P) press into PCB drilled holes, mechanically anchoring the SMT connector body so that mating forces are not transmitted solely through the 40-pin solder joints. This reduces the risk of pad lift and solder joint cracking in applications with repeated mating cycles or mechanical vibration.
When would an engineer choose TSM-120-03-TM-DH-P-TR over a version without board lock pegs?
Engineers select the board lock variant when the connector is used in equipment exposed to vibration, shock, or repeated plug-and-unplug operations where solder joint fatigue is a concern. For 40-pin connectors, the combined stress of mating forces across 2 rows can exceed the capacity of SMT pads alone, making the through-hole lock pegs a low-cost reliability enhancement.
Is TSM-120-03-TM-DH-P-TR packaged for automated assembly and what reel quantities are typically available?
Yes, the TR suffix confirms tape-and-reel packaging for TSM-120-03-TM-DH-P-TR, which is compatible with standard automated pick-and-place SMT machines. Samtec typically offers tape-and-reel connectors in reel quantities of 250 or 500 pieces, and buyers should verify current stock and reel count options with authorized distributors when planning production BOM procurement.
