Frequently Asked Questions
What contact plating does TST-102-03-S-D use for mating durability?
The TST-102-03-S-D uses 30 µin (microinches) gold plating over nickel on the mating contact surfaces, providing corrosion resistance and low contact resistance across hundreds to thousands of mate-demate cycles. The termination pins use tin over a nickel barrier for robust, solderable PCB through-hole termination in standard wave or hand-soldering processes.
How does the shrouded housing on TST-102-03-S-D prevent connector mismating in field installations?
The TST-102-03-S-D shrouded housing surrounds all 4 positions in a polarized rectangular shell that physically blocks incorrect cable insertion. This is critical in 0.100 inch pitch dual-row assemblies where reversing polarity can damage connected circuits, and the 0.365 inch body depth provides secure mechanical keying even in vibration-prone industrial or automotive environments.
Is TST-102-03-S-D compatible with standard 2.54 mm IDC ribbon cable connectors?
Yes, with 0.100 inch (2.54 mm) pitch on both rows, TST-102-03-S-D mates directly with standard IDC ribbon cable assemblies and discrete dupont-style female headers widely used in prototype and embedded development environments. Its 4-pin dual-row layout aligns with 8-conductor ribbon cable sections for simple field wiring in test fixtures and development kits.
For an ATE fixture requiring 1000-cycle connector life, how does TST-102-03-S-D's gold plating compare to tin contacts?
Gold-plated contacts on TST-102-03-S-D typically sustain 500 to 1000 or more reliable mate-demate cycles before measurable contact resistance increase, whereas tin contacts often degrade after 50 to 100 cycles due to oxide buildup. For automated test equipment where DUT boards are inserted and removed repeatedly, the 30 µin gold mating finish of TST-102-03-S-D provides significantly longer service life.
