What are the key features of TFM-139-22-FM-D-A-P-TR?
- Dual-row 78-position Tiger Eye terminal strip on 0.050 inch (1.27 mm) pitch for ultra-high-density board stacking interconnects
- Female mating contact gender (FM) accommodates male pin header mating partners in stackable PCB systems with secure low-profile engagement
- Tape-and-reel (TR) packaging enables high-speed automated pick-and-place on SMT lines without manual connector handling
What is TFM-139-22-FM-D-A-P-TR used for?
The TFM-139-22-FM-D-A-P-TR serves high-density mezzanine card and daughter card applications in FPGA development systems, telecommunications line cards, and embedded computing modules that demand a 0.050 inch pitch dual-row socket strip. Its Tiger Eye contact design ensures reliable wiping action and consistent signal integrity across the 78-position interface for high-cycle board stacking operations. The tape-and-reel format supports volume production assembly in server, networking, and defense electronics manufacturing.

Frequently Asked Questions
What is the contact pitch and total position count of the TFM-139-22-FM-D-A-P-TR?
The TFM-139-22-FM-D-A-P-TR uses a 0.050 inch (1.27 mm) pitch dual-row layout providing 78 total positions (39 per row). This high-density configuration suits mezzanine card and board stacking designs requiring many signal and power contacts in a compact 1.95 inch row length.
Which mating connectors are compatible with the TFM-139-22-FM-D-A-P-TR female contact strip?
The FM (female mating) designation on the TFM-139-22-FM-D-A-P-TR means it accepts SAMTEC TFM or TFW series male pin header strips with matching 0.050 inch pitch and 78-position dual-row layout. This allows designers to pair it with either straight or right-angle male counterparts depending on the stacking height requirement of 2 mm to 23 mm.
When should a design team choose the TFM-139-22-FM-D-A-P-TR over a 0.100 inch pitch alternative for board stacking?
The 0.050 inch pitch TFM-139-22-FM-D-A-P-TR is preferred when PCB real estate is constrained to under 2 square inches for a 78-signal interface. Compared to a 0.100 inch pitch connector carrying the same 78 positions, it reduces footprint length by approximately 50%, making it suitable for compact server blade, FPGA mezzanine, and defense avionics boards where board area costs exceed connector unit price differences.
