What are the key features of TSM-121-04-SM-DH-A-K-TR?
- 42-position 0.100" pitch dual-height surface mount terminal strip supporting flexible board-height interconnect configurations
- Gold-plated contact finish provides low contact resistance and superior corrosion resistance for long-term reliability
- Tape-and-reel (TR) packaging enables efficient automated pick-and-place SMT assembly in high-volume production
What is TSM-121-04-SM-DH-A-K-TR used for?
The TSM-121-04-SM-DH-A-K-TR is designed for high-count board-to-board and wire-to-board applications in embedded computing, telecommunications, and industrial automation systems requiring 42-position, 0.100" pitch surface mount connections. Its dual-height configuration allows PCB designers to select optimal standoff height for clearance above or below the board, accommodating components of varying heights in dense assemblies. The surface mount design integrates into automated SMT production while supporting signal and power routing across industrial control cards, test fixtures, and data acquisition modules.

Frequently Asked Questions
How does TSM-121-04-SM-DH-A-K-TR affect assembly planning?
Assembly planning should account for documented package, reel or bulk handling, inspection criteria, and 42 pins. Those details help contract manufacturers prepare placement, soldering, and receiving checks.
Which sourcing notes help avoid a wrong replacement for TSM-121-04-SM-DH-A-K-TR?
Replacement notes should require 42 pins, matching package constraints, compatible ratings, and the same functional category. This prevents a superficially similar part from breaking board fit or performance.
When should engineering request a datasheet check for TSM-121-04-SM-DH-A-K-TR?
Request a datasheet check whenever a quote, alternate, or lifecycle change affects 42 pins or the package. The review should happen before purchase order release for production quantities.
