Frequently Asked Questions
How many mating cycles does the Tiger Eye ELP contact system in SFM-135-02-L-D-DS support, and why does it matter for test equipment?
Samtec's Tiger Eye ELP (Extended Life Performance) contact system is designed for significantly higher mating cycle counts than standard socket contacts, often rated well beyond 100 cycles with consistent contact resistance. For test and measurement equipment where module boards are swapped repeatedly across 70 positions at 0.050 inch pitch, this high-cycle reliability prevents contact wear-related failures and maintains signal integrity across the life of the test system.
What is the position count and body length of SFM-135-02-L-D-DS, and how does this affect routing on a high-density daughter card?
SFM-135-02-L-D-DS provides 70 positions in a dual-row layout across a 2.35 inch body at 0.050 inch (1.27 mm) pitch. For FPGA daughter cards and high-density mezzanine boards, this 2.35 inch, 70-position footprint concentrates a large number of I/O and power connections in a compact area, leaving more PCB real estate for signal routing and component placement compared to a 0.100 inch pitch equivalent.
Is SFM-135-02-L-D-DS RoHS-compliant, and what contact finish does it use for lead-free solder compatibility?
SFM-135-02-L-D-DS uses a tin (Sn) over nickel (Ni) barrier contact finish on all 70 contacts, which is a standard lead-free, RoHS-compliant finish compatible with SAC305 solder paste and standard lead-free reflow profiles peaking around 245°C to 260°C. The nickel barrier prevents tin diffusion into the base metal, maintaining reliable solderability over time and through multiple thermal excursions.
For a procurement team, what lifecycle risk indicators should be monitored for SFM-135-02-L-D-DS across a multi-year production program?
The YTEOL (Years to End of Life) value of 9.4 for SFM-135-02-L-D-DS indicates a relatively long remaining lifecycle, providing procurement teams with a planning horizon of approximately 9 years before obsolescence risk increases. For multi-year programs, teams should confirm this value annually with Samtec, register for product lifecycle notifications, and qualify a form-fit-function alternate from the SFM series that matches the 70-position, 0.050 inch pitch, dual-row socket specification.
