Key Features
- 40-position dual-row 0.100 inch pitch SMT terminal strip for high-density board-to-board interconnects
- Dual-height (DH) body accommodates varied PCB stack-up heights and component clearance requirements
- Tape-and-reel (TR) packaging enables efficient automated SMT pick-and-place assembly in production environments
Applications
The TSM-120-02-H-DH-A-K-TR is suited for high-density signal and power distribution on industrial control boards, backplane assemblies, and embedded computing modules. Its 40-position dual-row 0.100" pitch layout provides a large number of reliable interconnect positions in a compact SMT footprint. The dual-height body design allows additional clearance for adjacent components or mating connectors in tight board layouts.

Frequently Asked Questions
How many positions does the TSM-120-02-H-DH-A-K-TR provide and in what row arrangement?
The TSM-120-02-H-DH-A-K-TR provides 40 positions arranged in 2 rows of 20 contacts each, with a 0.100 inch pitch. This dual-row configuration delivers high contact density for complex signal and power distribution interconnects on surface mount PCBs.
What does the dual-height (DH) designation mean for the TSM-120-02-H-DH-A-K-TR in PCB layout?
The dual-height designation means the TSM-120-02-H-DH-A-K-TR has a taller body profile than standard single-height SMT terminal strips, providing additional clearance above the PCB surface. This is beneficial when mating with through-hole or dual-height plug connectors, or when adjacent components require additional vertical clearance over the 0.100 inch pitch contact area.
Can TSM-120-02-H-DH-A-K-TR replace a through-hole 40-pin dual-row header in a board redesign?
Yes, the TSM-120-02-H-DH-A-K-TR can replace a through-hole 40-pin dual-row header when migrating to SMT assembly, as it provides the same 40-position 0.100 inch dual-row contact pattern. The SMT version reduces PCB drilling requirements and enables reflow soldering, which can reduce assembly cost in high-volume production runs compared to through-hole wave soldering.
