Key Features
- 36 positions in dual-row 0.100 inch pitch for high-density SMT signal interconnection
- TL through-layout termination for enhanced mechanical stability and solder joint strength
- Tape and reel (TR) packaging for automated high-volume pick-and-place SMT assembly
- DH dual-row configuration provides twice the pin density versus single-row connectors at the same pitch
- P polarization key feature preventing incorrect connector orientation during mating
Applications
The TSM-118-03-TL-DH-P-TR is used for board-to-board signal routing, module interface headers, and high-density PCB interconnects in industrial control systems, embedded computing platforms, and test equipment. Its 36-pin dual-row 0.100 inch pitch layout provides a practical balance of signal count and PCB footprint size for moderate-complexity interface designs requiring polarized mating connectors.

Frequently Asked Questions
How does the polarization feature (P suffix) of TSM-118-03-TL-DH-P-TR protect against incorrect mating in field-installed assemblies?
The P (polarization) feature in TSM-118-03-TL-DH-P-TR incorporates a mechanical key that physically prevents the connector from being inserted in the wrong orientation. In systems with 36-pin dual-row connectors at 0.100 inch pitch, reversed mating could short-circuit adjacent pins or damage ICs, making the polarization key critical for field-serviceable boards and modular assemblies where non-expert installation is expected.
What mechanical advantage does the TL through-layout termination of TSM-118-03-TL-DH-P-TR provide over standard surface-mount-only termination?
The TL through-layout termination style in TSM-118-03-TL-DH-P-TR anchors the connector body to the PCB by passing legs through board holes while solder pads remain on the top surface. This provides significantly greater pull-out strength compared to standard SMT-only termination, especially important for 36-pin connectors subject to repeated mating cycles or mechanical stress in industrial and test equipment applications.
How does TSM-118-03-TL-DH-P-TR compare to a 36-pin single-row connector in terms of PCB length required?
TSM-118-03-TL-DH-P-TR uses a dual-row DH layout with 0.100 inch (2.54 mm) pitch, which places 18 contacts per row to achieve 36 total pins. This dual-row arrangement requires approximately half the board edge length compared to a single-row 36-pin connector at the same pitch, freeing PCB real estate for other components in space-constrained designs.
What lead time or stock profile should procurement teams consider for TSM-118-03-TL-DH-P-TR in a medium-volume production run?
Samtec TSM series connectors are generally stocked or built-to-order with lead times ranging from 1 to 4 weeks depending on volume. For a medium-volume production run of 1000 to 5000 units, procurement teams should place orders at least 4 to 6 weeks ahead, and verify tape-and-reel minimum order quantities (typically 500 to 1000 pieces per reel) to avoid packaging surcharges on smaller orders.
