What are the key features of TFC-104-02-LM-D?
- 8-position dual-row terminal strip at 0.050" (1.27 mm) pitch with low-mating-force (LM) contacts for effortless board insertion and removal
- Tiger Eye gold flash mating contacts deliver reliable sub-20 milliohm contact resistance for up to 50 mating cycles at a lower cost than fully gold-plated contacts
- Dual-row layout concentrates 8 signal connections within approximately 5 mm of board length, ideal for ultra-compact PCB interface designs
- Tin (Sn) with nickel (Ni) barrier termination provides RoHS-compliant, corrosion-resistant solder joints compatible with lead-free reflow at 260°C peak
What is TFC-104-02-LM-D used for?
The TFC-104-02-LM-D is ideal for compact board stacking in microcontroller development boards, small form-factor I/O expansion modules, and sensor daughter boards requiring an 8-position 0.050" pitch dual-row interface with easy-insertion low-mating-force contacts. Its small footprint of approximately 5 mm connector length enables dense PCB layouts on credit-card-size and smaller embedded boards. The low mating force design also benefits portable consumer devices and wearables where repeated board assembly by hand requires minimal insertion force to avoid connector or PCB damage.

Frequently Asked Questions
What does the LM (low-mating-force) designation on TFC-104-02-LM-D mean, and how does it differ from standard mating force contacts?
The LM designation on TFC-104-02-LM-D indicates a low-mating-force contact geometry that requires approximately 30-50% less insertion force per contact compared to standard Tiger Eye contacts. For the 8-position dual-row configuration, total connector insertion force is reduced to roughly 40-80 grams versus 100-160 grams for standard force contacts, making the TFC-104-02-LM-D suitable for hand-assembly operations, portable device board swapping, and automated test fixtures requiring delicate board-to-board connection without risk of bending pins or damaging PCB pads.
How compact is the TFC-104-02-LM-D footprint, and what board stacking height options are available for this connector family?
The TFC-104-02-LM-D occupies approximately 5 mm of PCB length in its dual-row 0.050" pitch layout, with a body width of roughly 3.7 mm. In the TFC series, board stacking heights are defined by the mating socket strip stack height, typically ranging from 4 mm to 15 mm depending on the selected SFM or equivalent socket, enabling designers to choose the precise board separation distance required for component clearance between stacked PCBs.
For a compact IoT sensor node with 6-8 I/O signals between main board and RF daughtercard, why select TFC-104-02-LM-D over a single-row 0.100" header?
The TFC-104-02-LM-D provides 8 dual-row positions in a 5 mm by 3.7 mm footprint at 0.050" pitch, compared to a single-row 0.100" pitch 8-position header that would span 17.8 mm in length. This 70% reduction in connector length directly frees PCB area for antenna keep-out zones, battery connectors, or RF shielding on compact IoT sensor PCBs typically measuring 20 mm x 30 mm or smaller, where every square millimeter of board space impacts overall module size and cost.
What is the expected procurement availability for TFC-104-02-LM-D and how does the Tiger Eye series support cost-sensitive high-volume designs?
The TFC series Tiger Eye connectors from SAMTEC are catalog stocked items with typical distributor availability in quantities from 1 to 5,000 units, making them accessible for both prototype quantities and production runs. The cost-effective gold flash contact design reduces per-unit cost by approximately 25-40% compared to premium fully gold-plated alternatives, and the standard 0.050" pitch with 8 dual-row positions enables cross-compatible second-source options from multiple connector vendors, reducing single-source procurement risk for cost-sensitive consumer and industrial product designs.
