Key Features
- 38-position dual-row 2.54 mm pitch SMT terminal strip for high-density board-to-board interface designs
- Top-load (TL) contact design allows lower insertion force while maintaining reliable 2.54 mm pitch mating
- Key (K) polarization feature prevents mis-mating and ensures correct connector orientation in automated assembly
Applications
TSM-119-03-TL-DH-A-K-TR is suited for backplane expansion cards, multi-module industrial controllers, and high pin-count embedded computing boards requiring 38-position dual-row SMT connectivity at 2.54 mm pitch. The key (K) alignment feature ensures fail-safe mating in dense board assemblies where multiple connectors of similar pitch are placed in close proximity. Tape-and-reel packaging enables integration into automated SMT production workflows.

Frequently Asked Questions
How does the key (K) feature in TSM-119-03-TL-DH-A-K-TR prevent mis-mating in dense PCB assemblies?
The key (K) polarization feature in TSM-119-03-TL-DH-A-K-TR includes a mechanical keying slot that physically prevents insertion in the wrong orientation. In PCB assemblies with multiple 38-position connectors at 2.54 mm pitch, this prevents costly reverse-insertion damage and ensures correct pin alignment across all 38 positions during board assembly and field maintenance.
For a 38-pin dual-row backplane design, how much PCB length does TSM-119-03-TL-DH-A-K-TR occupy?
TSM-119-03-TL-DH-A-K-TR spans approximately 1.9 inches (48.3 mm) of PCB length to accommodate 19 contacts per row at 2.54 mm pitch in a dual-row configuration. The dual-row arrangement limits the connector's depth to the standard 2-row 2.54 mm pitch footprint (approximately 0.24 inches), making it significantly narrower than a single-row 38-position header.
What packaging format does TSM-119-03-TL-DH-A-K-TR use and how does it support production scaling?
TSM-119-03-TL-DH-A-K-TR is supplied in tape-and-reel (TR) packaging compatible with standard SMT pick-and-place equipment. The TR format enables consistent machine-placement accuracy at 2.54 mm pitch, supports reels holding hundreds of connectors per reel for uninterrupted production runs, and reduces manual handling errors when assembling boards with multiple 38-position connectors.
