What are the key features of TFM-140-12-S-D-LC?
- 80-position dual-row through-hole terminal strip with compact 0.050" (1.27 mm) pitch for high-density PCB signal routing
- Split board-lock (LC) mounting option mechanically secures the connector body to the PCB, preventing pull-out during mating
- Matte tin over nickel contact finish (50 µin) balances cost and corrosion resistance for industrial environments
- 2.125" body length supports long dual-row connector footprints on backplanes and mezzanine carrier boards
- One-week factory lead time and RoHS-compliant (Pb-free) construction for reliable supply chain planning
What is TFM-140-12-S-D-LC used for?
The TFM-140-12-S-D-LC is used in backplane interconnect systems, FPGA carrier boards, and industrial control modules where 80 signals must pass through a stable 0.050" pitch through-hole dual-row connector with positive board-lock retention. Its split board-lock feature prevents connector pull-out under repeated mating in test and measurement equipment or rack-mounted telecom line cards. The tin-over-nickel contact finish suits cost-sensitive industrial designs without sacrificing long-term reliability.

Frequently Asked Questions
What is the body length and pitch of the TFM-140-12-S-D-LC connector?
The TFM-140-12-S-D-LC has a body length of 2.125 inches and uses a 0.050" (1.27 mm) pitch dual-row layout with 80 total positions, providing high contact density in a through-hole format suitable for backplane and mezzanine PCB applications.
How does the split board-lock (LC) feature on TFM-140-12-S-D-LC improve mechanical reliability?
The LC (board-lock) mounting option on TFM-140-12-S-D-LC uses split retention features that snap into the PCB, preventing the 80-position connector from pulling out during mating and unmating cycles, which is critical for test and measurement rack systems and industrial backplanes subject to vibration.
What contact finish does TFM-140-12-S-D-LC use and how does it affect solderability?
The TFM-140-12-S-D-LC uses a matte tin over nickel (50 µin) contact finish that offers good solderability with standard wave or selective soldering processes and provides adequate corrosion resistance for indoor industrial environments across the connector's 80 positions.
Is TFM-140-12-S-D-LC RoHS compliant and what is the typical lead time?
Yes, the TFM-140-12-S-D-LC is RoHS compliant (Pb-free) with a factory lead time of approximately 1 week, making it practical for green-compliance regulated industrial and telecom designs requiring 80-position 0.050" pitch through-hole connectors on short procurement schedules.
