Frequently Asked Questions
What contact finish does the SQT-127-01-F-D use and how does it affect insertion reliability?
The SQT-127-01-F-D uses gold flash over nickel on the mating contacts and tin with a nickel barrier on the termination side. Gold flash provides low contact resistance and corrosion protection, supporting reliable mating cycles in industrial and instrumentation environments operating over a -55 °C to +125 °C temperature range.
How many positions and what pitch does the SQT-127-01-F-D provide for PCB socket applications?
The SQT-127-01-F-D offers 54 positions arranged in a dual-row configuration at 2.00 mm pitch. The body measures approximately 2.145 inches in length, making it suitable for high pin-count board-to-board connections in compact PCBs requiring reliable electrical contacts at 2.00 mm grid spacing.
Which industrial applications benefit most from the SQT-127-01-F-D rugged PCB socket design?
Industrial automation controllers, defense avionics, and telecommunications backplanes benefit most from the SQT-127-01-F-D because its FLEXYZ Tiger Buy contact technology tolerates PCB warpage and vibration. The 54-position dual-row configuration at 2.00 mm pitch supports high-density wiring in environments with shock loads up to 50 G and operating temperatures from -55 °C to +125 °C.
Is the SQT-127-01-F-D RoHS compliant and what lead-free termination does it use?
Yes, the SQT-127-01-F-D is fully RoHS compliant with a Pb-free rating. The termination contacts use a tin (Sn) finish with a nickel (Ni) barrier to prevent tin whisker growth, ensuring reliability in lead-free solder reflow processes at temperatures up to 260 °C and meeting IPC-A-610 Class 3 soldering requirements.
