What are the key features of TFM-142-04-SM-D-LC?
- Ultra-fine 1.27 mm (0.050") pitch dual-row SMT strip with 84 total positions for maximum density board interconnects
- Tiger Eye high-reliability contact system provides consistent low-resistance mating over thousands of insertion cycles
- Low-clearance (LC) profile reduces vertical stack height for space-critical high-density PCB designs
What is TFM-142-04-SM-D-LC used for?
The TFM-142-04-SM-D-LC is ideal for high-density board-to-board and module-to-board connections in telecommunications equipment, high-performance computing blades, and instrumentation systems. Its 1.27 mm pitch SMT dual-row configuration maximizes signal density in space-constrained designs, while the Tiger Eye contact technology ensures long-term reliability in high-cycle production and field-deployed assemblies.

Frequently Asked Questions
How many total contact positions does the TFM-142-04-SM-D-LC provide and at what pitch?
The TFM-142-04-SM-D-LC provides 84 total positions arranged in a dual-row layout at 1.27 mm (0.050") pitch, enabling very high signal density board-to-board connections in compact PCB assemblies used in computing, telecom, and instrumentation applications.
What makes the Tiger Eye contact system in the TFM-142-04-SM-D-LC suitable for high-cycle applications?
SAMTEC's Tiger Eye contact technology uses a dual-beam wiping action that maintains consistent low contact resistance over thousands of mating cycles; the TFM-142-04-SM-D-LC with this system is rated for high-reliability environments where connectors at 1.27 mm pitch must perform across repeated insertions without degradation.
For a telecom blade module requiring 84 signals in minimal board area, how does the TFM-142-04-SM-D-LC compare to 2.54 mm pitch alternatives?
The TFM-142-04-SM-D-LC at 1.27 mm pitch occupies roughly one-quarter the board footprint of equivalent 2.54 mm pitch dual-row strips for the same 84-position count, making it the preferred choice for blade servers and telecom line cards where every square millimeter of PCB area is at a premium.
What lead times and minimum order quantities should procurement teams plan for when sourcing the TFM-142-04-SM-D-LC?
The TFM-142-04-SM-D-LC is available through SAMTEC's authorized global distributors with typical stock for standard orders of 10 to 500 pieces; lead times for higher volumes of 1000+ units at 84-position 1.27 mm pitch generally run 4 to 8 weeks depending on distributor inventory and regional availability.
