What are the key features of TSM-126-03-H-DH-A-K-TR?
- 52-position dual-row SMT terminal strip on 0.100" (2.54 mm) pitch for standard PCB grid compatibility
- High-profile (H) standoff variant provides clearance for underlying PCB components beneath the connector
- Keying (K) option prevents connector mis-insertion in multi-row board assemblies
- Tape-and-reel (TR) packaging enables high-speed automated pick-and-place SMT assembly
What is TSM-126-03-H-DH-A-K-TR used for?
The TSM-126-03-H-DH-A-K-TR suits applications requiring 52-position high-density interconnects on standard 0.100" pitch grids, such as industrial backplanes, test and measurement equipment, and embedded controller boards. The high-profile standoff variant allows routing of other components beneath the connector body, maximizing PCB real estate. Keying prevents assembly errors in systems with multiple adjacent headers during automated or manual board build.

Frequently Asked Questions
Which designs should use TSM-126-03-H-DH-A-K-TR when 52 pins is required?
TSM-126-03-H-DH-A-K-TR is useful when the BOM needs a Connector matching the approved board-to-board or cable-to-board interconnect design. The available part context includes 52 pins, giving engineers a concrete parameter for datasheet and substitution checks.
How should layout teams verify 52 pins before approving TSM-126-03-H-DH-A-K-TR alternates?
For layout review, compare the approved Other footprint, assembly method, and manufacturer documentation before substituting. Keeping 52 pins visible helps avoid alternates that change routing, mating fit, or assembly qualification evidence.
What RFQ checks keep TSM-126-03-H-DH-A-K-TR aligned with the 52 pins requirement?
For RFQs, quote the exact TSM-126-03-H-DH-A-K-TR, SAMTEC manufacturer name, lifecycle expectations, and traceability needs. Supplier responses should preserve 52 pins or clearly explain any proposed alternate before purchase approval.
