Key Features
- 58-position dual-row layout on 0.100" (2.54 mm) pitch for dense I/O interconnect
- High-profile (H) body height for clearance over tall PCB components
- Alignment post (A) feature for precise positioning and polarization during SMT assembly
- Gold-plated contacts providing low contact resistance and long service life
- Tape-and-reel (TR) packaging compatible with automated pick-and-place SMT lines
Applications
The TSM-129-02-H-DH-A-P-TR is commonly used in industrial backplane systems, embedded computing daughtercards, and test equipment where 58 signal contacts are needed across a polarized dual-row SMT interface. The high-profile body version is selected when the PCB layout includes taller components adjacent to the connector that require additional clearance.

Frequently Asked Questions
Why would a designer choose the high-profile (H) body version of TSM-129-02-H-DH-A-P-TR over a standard-height variant?
The high-profile body provides additional vertical clearance above the PCB surface, useful when tall through-hole capacitors, inductors, or heat sinks are placed within 0.100" of the 58-position connector. This prevents mechanical interference during assembly and mating of daughter cards.
How many signal contacts does TSM-129-02-H-DH-A-P-TR provide, and in what configuration?
TSM-129-02-H-DH-A-P-TR provides 58 contacts arranged in a dual-row (DH) layout with 0.100" (2.54 mm) pitch. This dual-row format packs 58 pins into a board length equivalent to a 29-position single-row strip, doubling I/O density for space-constrained PCB designs.
What is the significance of the -P suffix in the TSM-129-02-H-DH-A-P-TR part number for procurement purposes?
The -P suffix in Samtec's TSM series typically denotes a specific plating or material option on the contact tail or housing, which can affect solder compatibility and corrosion resistance. Buyers should confirm the exact plating code in the Samtec datasheet before substituting with a non-P variant to ensure solderability under lead-free MSL 1 reflow conditions.
Is the TSM-129-02-H-DH-A-P-TR an active product suitable for long-term production builds?
Samtec's TSM series is actively manufactured with typical factory lead times of 2–3 weeks, and the -TR tape-and-reel variant is stocked by major distributors. For long-term builds requiring multi-year supply, buyers should confirm active status and request a lifecycle notice from Samtec to plan buffer stock for the 58-position variant.
