Key Features
- 100 positions (2x50) at 1.27 mm (0.050 inch) pitch enables very high channel density for signal and power routing on compact PCBs in a 66.7 mm body length
- -K polarization key physically prevents incorrect mating orientation, eliminating mis-insertion risk in automated and field-service assembly environments
- 3 µin gold-over-nickel mating contact finish on phosphor bronze spring contacts provides reliable low-resistance mating with cost-effective plating thickness
- Tape-and-reel (-TR) packaging and surface-mount termination support high-volume automated pick-and-place and lead-free reflow assembly processes
Applications
The TFC-150-02-FM-D-A-K-TR is designed for cost-sensitive high-density board-to-board connector applications in consumer electronics, industrial automation, and mid-tier instrumentation where 100 signals must pass across a mezzanine interface at 1.27 mm pitch. The Tiger Eye contact design reduces raw material cost compared to fully gold-plated alternatives while maintaining adequate mating performance for applications requiring fewer than 100 mating cycles. Tape-and-reel format supports volume SMT production runs common in IoT gateway modules, HMI panels, and embedded controller daughter cards.

Frequently Asked Questions
How many positions does TFC-150-02-FM-D-A-K-TR provide and what is its contact pitch?
The TFC-150-02-FM-D-A-K-TR provides 100 positions in a dual-row, 2x50 layout at 1.27 mm (0.050 inch) pitch. The connector body is 66.7 mm (2.625 inches) long and 5.73 mm (0.226 inch) deep, providing 100 signal or power channels in a compact PCB footprint suitable for dense mezzanine board designs.
What contact finish does TFC-150-02-FM-D-A-K-TR use and how does it differ from fully gold-plated alternatives?
The mating contacts have 3 µin gold over nickel, compared to 15 µin to 30 µin found in premium high-cycle connectors. The 3 µin Tiger Eye finish is adequate for applications requiring fewer than 50 to 100 mating cycles and reduces connector cost by 20% to 40% compared to fully gold-plated variants, making it practical for fixed or rarely disconnected board-stacking assemblies.
What role does the -K polarization key play in TFC-150-02-FM-D-A-K-TR installations?
The -K option adds a physical key to the connector housing that prevents insertion in the incorrect 180-degree rotated orientation. Without keying, a 100-pin dual-row connector can be mated backwards, applying all 100 signals to the wrong pins and potentially damaging ICs on both boards. Keying is mandatory in automated production and any assembly where operators cannot reliably orient connectors by visual inspection of the PCB silkscreen.
For which cost-driven mezzanine applications is TFC-150-02-FM-D-A-K-TR a practical alternative to premium connectors?
It is suited to fixed or low-cycle mezzanine interfaces such as IoT gateway modules, HMI daughter boards, and industrial sensor expanders where the connector is mated once during assembly and rarely disconnected. The Tiger Eye 3 µin gold finish reduces per-unit connector cost compared to SFM-series high-reliability variants with 20 µin gold, making it the preferred choice in price-sensitive designs that do not require field-serviceable mating.
