What are the key features of TSM-119-02-LM-DH-P-TR?
- 38 positions on 0.100 inch (2.54 mm) pitch dual-row SMT layout for high-density signal routing
- Low-profile mid-height (LM) design reduces connector height above the PCB for stacked board assemblies
- Polarization key (P) ensures correct connector orientation, preventing reverse mating during assembly
- Tape-and-reel (TR) packaging for automated pick-and-place SMT production
- Dual-row (DH) configuration provides 38 contacts in a compact PCB footprint compatible with SAMTEC TSW mating receptacles
What is TSM-119-02-LM-DH-P-TR used for?
TSM-119-02-LM-DH-P-TR is used in embedded computing platforms, industrial fieldbus modules, and FPGA development boards requiring a high pin-count 0.100 inch pitch SMT connector with height clearance control. The 38-position dual-row layout is commonly used for expansion headers, debug interfaces, and sensor array connections where a keyed, low-profile connector is needed. Tape-and-reel availability supports volume SMT manufacturing.

Frequently Asked Questions
How many connections does TSM-119-02-LM-DH-P-TR provide and what is the contact pitch?
TSM-119-02-LM-DH-P-TR provides 38 positions in a dual-row arrangement on a 0.100 inch (2.54 mm) pitch. This gives designers 38 discrete signal, power, or ground connections within a single surface-mount connector, reducing the number of connectors needed and simplifying board-to-board wiring in industrial and embedded systems.
What does the LM (low-profile mid-height) designation mean for board-stack clearance in TSM-119-02-LM-DH-P-TR?
The LM suffix in TSM-119-02-LM-DH-P-TR designates a low-profile mid-height variant, meaning the connector has a shorter standoff above the PCB surface than full-height TSM versions. This is important in stacked or sandwiched board assemblies where the gap between two PCBs is limited to a few millimeters, and using a standard-height connector would prevent the boards from mating properly.
Can the polarization key in TSM-119-02-LM-DH-P-TR be relied on for error-proof assembly of a 38-pin interface?
Yes. The P polarization key provides a physical block that prevents the 38-pin, 2.54 mm pitch connector from being inserted in reverse, which is particularly useful when the PCB has multiple similarly-sized connectors that are hard to distinguish visually. This reduces incorrect insertion errors on both production assembly lines and during field maintenance of industrial modules.
What lifecycle and procurement factors should buyers consider for TSM-119-02-LM-DH-P-TR?
Buyers should verify the current lifecycle status of TSM-119-02-LM-DH-P-TR directly with SAMTEC or authorized distributors, as connector product families can have variants that reach NRND status. For a 38-position, 2.54 mm pitch dual-row SMT connector, it is advisable to review SAMTEC's TSM product family for active pin-count alternatives if long-term supply continuity beyond 5 years is required.
