What are the key features of TFM-104-03-LM-D-LC?
- Tiger Eye contact system with gold-plated contacts for low-resistance, high-cycle-count mating in demanding telecom and defense applications
- 4-position dual-row layout (8 total contacts) at 0.050" (1.27 mm) pitch with low-midwall (LM) housing for reduced stacking height
- Surface-mount LC package enables automated reflow at up to 260°C without through-hole drilling, streamlining high-volume PCB assembly
What is TFM-104-03-LM-D-LC used for?
The TFM-104-03-LM-D-LC is suited for compact board-to-board and mezzanine interconnect in space-constrained applications such as RF front-end modules, FPGA daughter cards, and miniature sensor nodes requiring 8 contacts at 1.27 mm pitch. Its low-midwall housing reduces the overall stacking height between mated boards, enabling slim-profile assemblies in portable instruments and airborne electronics. Defense and industrial automation equipment also benefit from the Tiger Eye reliability for connectors that must maintain signal integrity through thousands of mating cycles.

Frequently Asked Questions
What does the LM suffix indicate on the TFM-104-03-LM-D-LC, and how does it affect board stack height?
The LM suffix designates a low-midwall housing variant, which reduces the plastic wall height between mated connectors compared to a standard midwall configuration. In practice this lowers the board-to-board stack height by approximately 0.5 mm to 1 mm relative to a standard TFM housing, enabling slimmer mezzanine assemblies in portable instruments, avionics modules, and wearable electronics where every millimeter of vertical clearance matters.
For a design needing only 8 signals in the densest footprint possible, how does TFM-104-03-LM-D-LC compare to a 2.54 mm pitch alternative?
The TFM-104-03-LM-D-LC places 8 contacts at 0.050" (1.27 mm) pitch in a dual-row 4-position footprint occupying approximately 5 mm x 6 mm of board area. An equivalent 2.54 mm pitch dual-row 4-position header would require roughly 10 mm x 12 mm, meaning the TFM-104-03-LM-D-LC offers approximately 4 times the contact density per unit area—critical in RF and high-frequency PCB layouts where signal trace lengths must be minimized.
Which procurement channels stock the TFM-104-03-LM-D-LC, and what lead times should buyers expect?
The TFM-104-03-LM-D-LC is available through SAMTEC's global network of authorized distributors including Digi-Key, Mouser, and Arrow, which typically stock standard Tiger Eye series connectors with lead times of 1 to 2 weeks for standard quantities. Custom configurations or reel quantities may require 4 to 8 weeks depending on production scheduling. SAMTEC also offers free samples for qualified engineers evaluating the 1.27 mm pitch Tiger Eye platform for new designs.
What mating connector is compatible with the TFM-104-03-LM-D-LC in a board-to-board stack?
The TFM-104-03-LM-D-LC mates with SAMTEC Tiger Eye receptacle strips in the SFML or SFM family at 0.050" (1.27 mm) pitch in matching dual-row 4-position configurations. These receptacles provide spring-loaded contacts that maintain a normal force of approximately 100 grams per contact, ensuring stable electrical connection over thousands of mate-and-unmate cycles even in high-vibration environments such as vehicle electronics or industrial machinery.
