What are the key features of TFC-123-02-FM-D-A?
- 46-position dual-row layout at 0.050" (1.27 mm) pitch delivering medium-density board-to-board signal routing in a compact PCB footprint
- Tiger Eye bifurcated contact geometry producing reliable wiping action for consistently low contact resistance across repeated mating cycles
- Cost-effective terminal strip design balancing SAMTEC reliability with reduced unit cost for budget-conscious production programs
What is TFC-123-02-FM-D-A used for?
The TFC-123-02-FM-D-A is used in data communication modules, industrial automation daughter cards, and embedded computing mezzanine assemblies requiring 46 dual-row connections at 0.050" pitch. Its cost-effective construction makes it a preferred choice for medium-volume production runs in network appliances, programmable logic controller expansion cards, and smart sensor boards. Engineers specify this terminal strip when signal density requirements exceed 40 contacts but premium-tier connector pricing is not warranted.

Frequently Asked Questions
How does the 46-position TFC-123-02-FM-D-A compare to lower-position SAMTEC terminal strips for signal routing?
The 46-position TFC-123-02-FM-D-A provides 24 more contact positions than a 22-position strip at the same 0.050" (1.27 mm) pitch, allowing designers to route additional address lines, data bus bits, or power rails without adding a second connector. This reduces BOM complexity and simplifies PCB routing in daughter card and mezzanine designs needing 23 to 46 simultaneous connections.
What contact technology ensures signal reliability in the TFC-123-02-FM-D-A under repeated mating?
The TFC-123-02-FM-D-A uses SAMTEC's Tiger Eye bifurcated spring contacts, which generate a mechanical wiping motion during insertion across all 46 positions. This wiping action removes surface oxides and contamination, maintaining contact resistance well below 50 milliohms even after hundreds of mating cycles—critical for module and daughter card systems that undergo repeated handling in test and field-service operations.
Which board-level assembly designs benefit most from the 46-position dual-row 0.050" pitch of the TFC-123-02-FM-D-A?
Boards requiring medium-density interconnects such as industrial controller expansion modules, wireless subsystem add-on cards, and 16-bit or 32-bit data bus daughter cards benefit most from the TFC-123-02-FM-D-A. The 46-position dual-row 0.050" pitch provides sufficient contact count for combined address, data, control, power, and ground routing in a single connector with a small PCB footprint.
Is the TFC-123-02-FM-D-A available in quantity from distribution, and what is its lead time profile?
The TFC-123-02-FM-D-A is part of SAMTEC's standard cost-effective TFC terminal strip series, which is typically stocked by major global distributors for same-day or next-day shipment on standard quantities. For production volume orders exceeding several thousand pieces, lead times from SAMTEC's factory typically range from 4 to 10 weeks depending on demand; distributor stock can bridge short-term gaps during supply-constrained periods.
