What are the key features of TSM-119-04-STL-DH-A-K-TR?
- 38-position dual-row layout on 0.100" (2.54 mm) pitch delivers high pin density for complex board-to-board or board-to-wire interconnects
- Tape-and-reel (TR) packaging enables seamless integration into automated SMT pick-and-place production lines for high-volume builds
- Keying (K) feature prevents mismate with non-keyed connectors, protecting 38 signal contacts in field-service and multi-connector board designs
What is TSM-119-04-STL-DH-A-K-TR used for?
The TSM-119-04-STL-DH-A-K-TR is designed for dense board-to-wire and board-to-board interconnect in industrial automation, communications infrastructure, and embedded computing equipment. Its 38-position dual-row configuration supports high-signal-count interfaces such as parallel buses, backplane connections, and modular expansion cards where compact routing is critical. The tape-and-reel format and SMT footprint make it ideal for automated assembly in high-volume production environments.

Frequently Asked Questions
How many positions and rows does the TSM-119-04-STL-DH-A-K-TR connector have?
The TSM-119-04-STL-DH-A-K-TR provides 38 positions arranged in a dual-row layout on a 0.100" (2.54 mm) pitch. This dual-row configuration carries twice as many signals per unit length as a single-row header, making it suitable for high-pin-count parallel bus and backplane applications in embedded and industrial systems.
What does the keying (K) option on TSM-119-04-STL-DH-A-K-TR prevent during connector mating?
The keying (K) option on the TSM-119-04-STL-DH-A-K-TR physically prevents mating with non-keyed or misoriented connectors, protecting all 38 contact pins from damage due to incorrect insertion. This is especially important in multi-connector board designs where two visually similar connectors could otherwise be swapped, causing signal cross-connection or circuit damage.
Is the TSM-119-04-STL-DH-A-K-TR suitable for automated SMT assembly?
Yes, the TR (tape-and-reel) packaging of the TSM-119-04-STL-DH-A-K-TR is specifically designed for automated pick-and-place equipment. The surface-mount short-tail termination supports standard reflow soldering at temperatures up to 260°C, consistent with lead-free solder profiles used in high-volume PCB production.
What is the contact pitch of the TSM-119-04-STL-DH-A-K-TR and which mating connectors are compatible?
The TSM-119-04-STL-DH-A-K-TR uses a 0.100" (2.54 mm) contact pitch, which is compatible with standard 0.100" mating socket housings such as SAMTEC's SSM or SSQ series as well as IDC ribbon cable assemblies designed for 2.54 mm dual-row headers. Always verify the keying slot alignment to ensure the correct mating connector is selected for the 38-pin dual-row footprint.
