What are the key features of TFM-147-23-F-D?
- Tiger Eye contact technology provides superior wipe action and redundant contact points, achieving mating reliability beyond 1000 insertion cycles
- 0.050 inch (1.27 mm) pitch dual-row layout supports 94 signal positions in a compact body, enabling high-density board-to-board connectivity
- High-reliability PTH design with gold-plated contacts resists corrosion and maintains consistent contact resistance across wide temperature ranges
- Compatible with SAMTEC TFM series ecosystem of mating receptacles and shrouded headers for flexible system-level stacking architectures
What is TFM-147-23-F-D used for?
TFM-147-23-F-D is used in defense avionics, aerospace payload modules, and high-reliability industrial controllers where repeated mating cycles and signal integrity at 0.050 inch pitch are critical requirements. The Tiger Eye contact design ensures robust electrical contact even after hundreds of insertions, making it suitable for field-serviceable plug-in boards and test equipment that undergo frequent connector engagement. Its high pin count and fine pitch also make it appropriate for FPGA mezzanine cards, data acquisition modules, and rugged embedded computing platforms.

Frequently Asked Questions
What makes the Tiger Eye contact technology in TFM-147-23-F-D more reliable than standard terminal strip contacts?
SAMTEC Tiger Eye contacts use a dual-beam contact design that delivers a wiping action during mating, displacing contaminants and oxide films to establish a low-resistance metal-to-metal connection. This design achieves reliable mating beyond 1000 insertion cycles compared to 100 to 200 cycles typical of standard single-beam contacts, making TFM-147-23-F-D well-suited for field-serviceable avionics line-replaceable units and test equipment where frequent connector engagement is unavoidable.
How many signal positions does TFM-147-23-F-D provide, and what pitch does it use for high-density layouts?
TFM-147-23-F-D provides 94 positions in a dual-row configuration with 0.050 inch (1.27 mm) pitch. This fine pitch packs 94 signals into a significantly shorter body than 2 mm or 2.54 mm alternatives would require, allowing designers to route high pin count interfaces such as parallel buses, FMC (FPGA Mezzanine Card) connectors, or multi-channel sensor arrays within tight PCB area budgets on defense or aerospace circuit cards.
For FPGA mezzanine card designs, how does TFM-147-23-F-D compare to FMC LPC connectors in pin count and pitch?
FMC LPC connectors typically provide 160 pins at 0.8 mm pitch in a standardized VITA 57.1 format, while TFM-147-23-F-D offers 94 positions at 0.050 inch (1.27 mm) pitch in a simpler 2-row PTH arrangement. For custom mezzanine designs that do not require full FMC compliance but need high reliability and 50 to 94 signal lanes, TFM-147-23-F-D is a cost-effective alternative with Tiger Eye durability that exceeds 1000 mating cycles and is easier to rework at the board level.
What operating temperature range does TFM-147-23-F-D support, and in which harsh-environment programs has SAMTEC qualified this series?
SAMTEC TFM-series connectors including TFM-147-23-F-D are rated for operation from -55°C to +125°C, covering the full military and aerospace temperature range. The gold-plated contacts and high-reliability PTH construction meet the durability needs of MIL-DTL-55302 class programs, shipboard electronics, and space-adjacent payload designs where thermal cycling, vibration, and humidity exposure would degrade standard commercial connector contacts over a 10-year to 20-year mission life.
