Frequently Asked Questions
What is the contact pitch of SQT-120-01-F-D and how does it compare to standard 0.100" connectors?
The SQT-120-01-F-D uses a 0.050" (1.27 mm) pitch, which is half the spacing of standard 0.100" connectors. This finer pitch allows 40 contacts to be routed in roughly half the PCB board space, making it ideal for compact daughtercard and FPGA module designs where high-density interconnection is a priority.
What contact finish does SQT-120-01-F-D use, and does it support multiple mating cycles?
The SQT-120-01-F-D uses gold flash over a 50 µin nickel barrier as the mating contact finish. Gold plating ensures stable low contact resistance and protects against oxidation. This finish supports reliable performance over repeated mating cycles, making the part suitable for socketed module designs that require periodic removal and reinsertion.
Is the SQT-120-01-F-D RoHS compliant, and can it be used in lead-free assembly processes?
Yes. The SQT-120-01-F-D is fully RoHS compliant and lead-free (Pbfree Code: Yes), making it compatible with standard lead-free reflow and wave soldering assembly processes. Its 40-pin through-hole configuration can be soldered using conventional automated wave solder equipment for high-volume production environments.
