What are the key features of TFC-109-02-F-D?
- 18-position dual-row male board stacking connector at 0.050" (1.27 mm) pitch for high-density signal routing in compact PCB designs
- Tiger Eye gold flash (3 micro-inch) mating contacts deliver reliable low-resistance connections rated for up to 50 mating cycles at reduced cost
- Tin (Sn) with nickel (Ni) barrier termination contacts provide corrosion-resistant, RoHS-compliant lead-free solder joint integrity
- 8.65-year YTEOL rating ensures long-term supply availability for designs with extended production or service life requirements
What is TFC-109-02-F-D used for?
The TFC-109-02-F-D board stacking connector is used in compact embedded systems, sensor interface modules, and industrial I/O expansion boards requiring an 18-position 0.050" pitch dual-row male strip for mating with corresponding female socket strips. Its gold flash contacts and cost-effective Tiger Eye design make it a practical choice for prototyping and moderate-volume production where mating cycles are limited to under 50 insertions. The connector's standard pitch and dual-row layout are well suited for SOM-to-carrier-board interfaces and modular datalogger expansion connectors.

Frequently Asked Questions
How many positions and what pitch does the TFC-109-02-F-D provide, and which complementary SAMTEC socket strip does it mate with?
The TFC-109-02-F-D provides 18 positions in a dual-row layout at 0.050" (1.27 mm) pitch. It mates with SAMTEC SFM series or equivalent Tiger Eye socket strips sharing the same 0.050" pitch and dual-row configuration, such as the SFM-109-02 female socket series, creating a 18-position board stacking interface with typical contact resistance under 20 milliohms at rated current.
What does gold flash (3 micro-inch) contact finish on TFC-109-02-F-D mean for mating cycle longevity and insertion force?
The 3 micro-inch gold flash finish on TFC-109-02-F-D mating contacts provides approximately 50 mating cycle durability while maintaining contact resistance below 20 milliohms throughout. Insertion force for the 18-position dual-row configuration is typically 50-100 grams per contact row depending on the mating socket's contact normal force, resulting in a total connector insertion force of approximately 100-200 grams for the complete 18-position assembly—manageable for manual board swapping in prototyping environments.
For which compact embedded or modular system designs is an 18-position 0.050" pitch dual-row connector like TFC-109-02-F-D most appropriate?
The TFC-109-02-F-D 18-position board stacking connector is well suited for Arduino-format shield interfaces, Raspberry Pi HAT expansion connectors, and modular sensor breakout boards requiring 16-20 signal lines in under 12 mm of board length. Its 0.050" pitch provides twice the contact density of a standard 0.100" header in the same space, making it the preferred choice for compact industrial HMI modules, IMU sensor boards, and multi-channel ADC expansion cards.
What procurement advantages does the TFC-109-02-F-D offer compared to higher-cost fully gold-plated SAMTEC connectors for a 5,000-unit production run?
The TFC-109-02-F-D Tiger Eye cost-effective series typically costs 30-50% less per unit than SAMTEC's fully gold-plated equivalents, translating to hundreds of dollars in savings on a 5,000-unit run of 18-position dual-row connectors. The YTEOL of 8.65 years also guarantees supply continuity for procurement planners managing multi-year production contracts, avoiding the obsolescence risk that requires costly redesigns when short-YTEOL parts disappear from distributor catalogs within 2-3 years of design introduction.
