What are the key features of TFM-142-04-FM-D-LC?
- 0.050" (1.27 mm) pitch dual-row female SMT terminal strip with 42 positions per row (84 total contacts) in a low-clearance (LC) configuration for ultra-dense mezzanine stacking
- Female (FM) SMT contact style mates directly with male Tiger Eye pin strips, providing a robust board-to-board stack with positive mechanical retention
- Low-clearance design reduces board-to-board stack height for space-critical multi-board assemblies in telecommunications, computing, and industrial modules
What is TFM-142-04-FM-D-LC used for?
The TFM-142-04-FM-D-LC is engineered for high-density mezzanine board stacking in FPGA carrier boards, embedded computing modules, and telecom line cards requiring 84-contact dual-row female interconnects. Its female SMT low-clearance design enables compact multi-board assemblies with minimal vertical stack height in chassis-constrained systems. Engineers select it for signal-intensive applications in data center equipment, military electronics, and high-speed digital test systems operating at 0.050-inch pitch.

Frequently Asked Questions
What is the FM suffix in TFM-142-04-FM-D-LC and how does it affect mating compatibility?
The FM suffix designates a female contact style on the TFM-142-04-FM-D-LC, meaning it accepts male pin strip counterparts from the TFM series. This female SMT terminal strip mates with corresponding male Tiger Eye strips at 0.050-inch pitch, providing a complete board-to-board stack with 84 contacts and secure mechanical retention across repeated mating cycles.
How many total contacts does the TFM-142-04-FM-D-LC provide for a mezzanine design?
The TFM-142-04-FM-D-LC provides 84 total contacts in a dual-row configuration with 42 positions per row at 0.050 inch (1.27 mm) pitch. This high contact count supports complex signal and power routing in FPGA mezzanine modules, DSP carrier boards, and multi-function industrial controller boards requiring dense interconnects.
When should designers select TFM-142-04-FM-D-LC over through-hole terminal strip alternatives?
Designers should select the TFM-142-04-FM-D-LC when SMT assembly compatibility and low board-to-board stack height are required, as the SMT footprint supports automated pick-and-place reflow soldering up to 260°C. Through-hole alternatives require manual soldering or wave soldering, adding process complexity; the LC low-clearance SMT variant minimizes vertical clearance in multi-board assemblies with 84 contacts at 0.050-inch pitch.
What stack-height advantage does the LC option provide in TFM-142-04-FM-D-LC for chassis-constrained systems?
The LC (low-clearance) option in TFM-142-04-FM-D-LC reduces the physical board-to-board gap compared to standard height variants, often saving several millimeters of vertical clearance. In chassis-constrained systems such as 1U rackmount servers or compact industrial PLCs, this reduced stack height enables fitting additional PCB layers or components while maintaining 84-contact connectivity at 0.050-inch pitch.
