What are the key features of TSM-131-04-SM-DH-A-K-TR?
- 62-position dual-row layout at 0.100" (2.54 mm) pitch delivering 31 contacts per row for high-density board-level signal buses in a standard surface mount footprint
- Key-lock (K suffix) polarization prevents mismating on boards with multiple adjacent connectors, protecting circuit integrity across all 62 positions
- Tape-and-reel (TR) and surface mount (SM) termination style with 4.06 mm post height enables seamless automated pick-and-place assembly in high-volume production
What is TSM-131-04-SM-DH-A-K-TR used for?
TSM-131-04-SM-DH-A-K-TR is suited for high-density backplane and multi-board expansion designs requiring 62 signal connections in a 0.100" pitch header footprint, such as industrial single-board computers, FPGA carrier boards, and modular I/O expansion systems. Its key-lock feature and surface mount construction make it especially practical for rack-mount servers and embedded computing platforms where multiple large connectors are mounted in close proximity and reliable automated assembly is a priority.

Frequently Asked Questions
How many contacts per row does TSM-131-04-SM-DH-A-K-TR have and what is the total body length?
TSM-131-04-SM-DH-A-K-TR has 31 contacts per row in a dual-row configuration, totaling 62 positions at 0.100" (2.54 mm) pitch. The body length spans approximately 78 mm (31 positions × 2.54 mm), making it one of the longest TSM series headers and suitable for wide bus interfaces such as parallel data buses or multi-channel analog front ends that need more than 50 pins in a single connector.
What is the post height of TSM-131-04-SM-DH-A-K-TR, and how does it interact with mating socket selection?
The 04 designation indicates a post height of approximately 4.06 mm (0.160 inch) above the PCB surface. This post length must be matched to a compatible dual-row socket strip with a corresponding receptacle depth to achieve full mating engagement. Insufficient socket depth can result in incomplete contact engagement and increased contact resistance above the typical 20 milliohm specification for this pitch.
Why choose a 62-position connector like TSM-131-04-SM-DH-A-K-TR over two separate 31-position connectors?
A single 62-position connector reduces the number of PCB mounting features and eliminates the alignment gap between two separate 31-pin headers, which can cause mechanical stress concentrations and board warpage in reflow. Using one connector also simplifies BOM management and reduces the risk of incorrect part placement in automated assembly, as only one component type needs to be loaded into the pick-and-place feeder for the entire 62-pin interface.
Is TSM-131-04-SM-DH-A-K-TR compatible with daughtercard designs using standard 0.100" socket strips?
Yes, TSM-131-04-SM-DH-A-K-TR uses the industry-standard 0.100" (2.54 mm) dual-row pitch, making the 62 posts mechanically compatible with most 0.100" dual-row socket strips. The key-lock (K) polarization feature provides an additional anti-mismating safeguard when paired with the matching SAMTEC socket variant, and the surface mount with 4.06 mm posts is compatible with standard 2.54 mm pitch through-hole sockets for board stacking configurations.
