Key Features
- Dual-row 7-position surface-mount terminal strip at 0.050" (1.27 mm) pitch offers 14 total contacts in a minimal board footprint for compact embedded signal routing
- Samtec Tiger Eye contact geometry provides a wiping-action mating interface that maintains low contact resistance in vibration-prone industrial and aerospace environments
- Lead-compatible (LC) contact finish meets RoHS compliance requirements while supporting tin-lead solder processes used in military and high-reliability production
Applications
The TFM-107-05-SM-D-LC suits high-density signal interconnects on FPGA evaluation boards, RF front-end modules, and military or aerospace PCB assemblies that mandate lead-compatible processing. Its 14 contacts at 1.27 mm pitch cover digital control buses, SPI or I2C interfaces, and differential pair routing within a compact surface-mount body. The Tiger Eye contact design reduces fretting corrosion risk in environments with vibration and thermal cycling.

Frequently Asked Questions
What does the LC suffix signify on the TFM-107-05-SM-D-LC, and which production environments benefit from it?
The LC suffix denotes a lead-compatible contact finish, allowing the TFM-107-05-SM-D-LC to be processed with tin-lead (SnPb) solder pastes in addition to lead-free alloys. Military, aerospace, and high-reliability programs that hold exemptions to RoHS restrictions often mandate tin-lead soldering to avoid tin whisker growth on pure-tin finishes used in standard commercial connectors.
How many total contacts does the TFM-107-05-SM-D-LC provide, and what signal interfaces does that support?
With 7 positions per row and 2 rows, the TFM-107-05-SM-D-LC provides 14 total contacts at 0.050" (1.27 mm) pitch. This is sufficient to carry a full SPI bus with chip select, a 4-lane differential pair set, or multiple PWM and GPIO signals between a microcontroller module and a daughter card in a compact embedded system.
What advantage does the Tiger Eye contact geometry provide in the TFM-107-05-SM-D-LC compared to a standard tuning-fork contact?
Tiger Eye contacts produce a controlled wiping action as the mating plug is inserted, displacing surface oxides and achieving consistent contact resistance below 20 mΩ. This is particularly valuable for low-level analog and RF signal paths where a high-resistance or intermittent contact at 1.27 mm pitch can degrade signal integrity or cause measurement errors.
For a prototype board that may need repeated connector swaps, how durable is the TFM-107-05-SM-D-LC mating cycle rating?
Samtec Tiger Eye terminal strips are typically rated for a minimum of 100 mating cycles. For a 14-contact, 1.27 mm pitch connector used on a prototype bench where daughter cards are swapped frequently, this durability is significantly higher than standard 0.100" pitch single-wipe contacts, which often degrade measurably after 50 cycles.
