What are the key features of TSM-139-01-F-DV-P-TR?
- 78-position dual-row configuration on 2.54 mm (0.100") pitch offers high signal density for SMT board-to-board interconnects
- Female (F) contact style with gold-plated spring contacts rated at 3 A per pin for low-resistance, reliable mating
- Surface mount termination compatible with standard reflow soldering for automated PCB assembly
- Tape-and-reel (TR) packaging enables high-volume pick-and-place production with consistent 2.54 mm pitch placement
What is TSM-139-01-F-DV-P-TR used for?
TSM-139-01-F-DV-P-TR is well suited for high-density backplane interconnects, industrial I/O expansion cards, and embedded computing boards that require 78 signal or power connections on a 2.54 mm pitch SMT footprint. Its female contact style mates directly with standard dual-row male headers, facilitating modular system designs and daughter card configurations. The tape-and-reel format simplifies integration into automated assembly lines for high-volume production.

Frequently Asked Questions
How many positions and rows does TSM-139-01-F-DV-P-TR offer, and what contact pitch is used?
TSM-139-01-F-DV-P-TR provides 78 positions arranged in 2 rows on a 2.54 mm (0.100 inch) pitch, giving 39 contacts per row. This dual-row layout routes a large number of signals in a compact SMT footprint, making it practical for backplane and daughter card applications where board real estate is limited.
What current rating do the contacts in TSM-139-01-F-DV-P-TR support, and how does this affect mixed power-signal designs?
Each contact in TSM-139-01-F-DV-P-TR is rated at approximately 3 A. In a mixed power-signal design, engineers can assign multiple adjacent pins to a single power rail — for example, 4 pins in parallel supply up to 12 A — while the remaining positions carry logic-level signals, maximizing the utility of all 78 contacts in a single connector.
How does TSM-139-01-F-DV-P-TR compare to a through-hole dual-row 78-pin connector for high-volume PCB production?
TSM-139-01-F-DV-P-TR uses surface mount termination and ships in tape-and-reel (TR) format, enabling automated pick-and-place and reflow soldering that is faster and more cost-effective at high volumes than manually inserting through-hole 78-pin connectors. The SMT profile also reduces PCB thickness requirements, which is advantageous for compact embedded systems where overall board stack height is constrained.
