What are the key features of TFC-136-02-L-D-A-K-TR?
- 72-position dual-row layout at 1.27mm (0.050-inch) pitch enables 72 signal connections in a compact 47mm board footprint
- Tiger Eye contact design provides reliable 30-gram insertion force per contact for consistent mating with 0.025-inch square posts
- Gold-plated contact finish ensures low contact resistance and extended service life in high-cycle wire termination applications
- Through-hole pin configuration with tape-and-reel packaging supports automated PCB insertion and reflow or wave soldering
- Cost-effective terminal strip construction reduces per-position connector cost in high-density backplane and wiring harness assemblies
What is TFC-136-02-L-D-A-K-TR used for?
The TFC-136-02-L-D-A-K-TR is used in PCB-to-wire termination panels for test and measurement equipment where 72 signal lines must be reliably connected to external instruments or harnesses at 1.27mm pitch. Backplane wiring in embedded computing chassis and VME or CompactPCI card cages use this terminal strip to route power and I/O signals between boards via wire-wrap or IDC cable assemblies. Industrial control panels and automated test fixture boards also deploy this connector for dense field-wiring termination at low cost per connection point.

Frequently Asked Questions
How many positions does the TFC-136-02-L-D-A-K-TR provide and at what pin pitch?
The TFC-136-02-L-D-A-K-TR offers 72 positions arranged in a dual-row configuration at 1.27mm (0.050-inch) pitch. This layout accommodates 72 independent signal or power connections within a PCB footprint of approximately 47mm × 5mm, making it one of the denser through-hole terminal strip options in the Samtec TFC series for high-signal-count wiring applications.
What wiring termination styles are compatible with the TFC-136-02-L-D-A-K-TR?
The TFC-136-02-L-D-A-K-TR is compatible with 0.025-inch square-post wire-wrap and IDC (insulation displacement connector) cable termination methods, accommodating AWG 26–28 wire. These termination options allow field wiring personnel to connect and reconnect individual signal lines without soldering, reducing rework time in prototype and service environments by more than 50% compared to direct solder termination.
For a 48-channel data acquisition system, why would a designer choose TFC-136-02-L-D-A-K-TR over two separate 36-position single-row connectors?
The dual-row TFC-136-02-L-D-A-K-TR consolidates all 72 positions (providing headroom for 48 analog channels plus digital ground and power returns) into a single 47mm PCB footprint, reducing board area by approximately 40% compared to two separate 36-position 1.27mm-pitch single-row connectors mounted side by side. A single connector also reduces assembly time and eliminates the alignment errors that can occur when two separate housings are placed adjacently.
Is the TFC-136-02-L-D-A-K-TR suitable for automated PCB assembly on a pick-and-place line?
Yes, the -TR suffix indicates tape-and-reel packaging with standard 16mm or 24mm carrier tape compatible with automated SMT pick-and-place equipment. Although the TFC is a through-hole component requiring a separate insertion step (not reflow), the tape-and-reel format ensures precise feeder presentation at rates of 2000–4000 placements per hour on auto-insertion machines, reducing hand-loading labor on high-volume production runs.
