Frequently Asked Questions
What is the pitch and contact count of the SQT-138-01-F-D socket?
The SQT-138-01-F-D features a 2.00 mm pitch with 76 positions arranged in a double-row configuration, providing reliable board-to-board connectivity across 38 positions per row for dense PCB assemblies.
What contact finish does the SQT-138-01-F-D use for mating and termination?
The mating contacts use gold flash over nickel (50 micro-inches), while the termination contacts use tin (Sn) with a nickel (Ni) barrier. This finish combination ensures low-resistance connections and good solderability for PCB mounting.
Which industrial or computing applications benefit most from the SQT-138-01-F-D connector?
This 76-position, 2.00 mm pitch socket is well suited for backplane interconnects, modular industrial controllers, telecom line cards, and embedded computing boards where a rugged PCB socket with reliable 2.00 mm mating is required across high pin counts.
What body dimensions should PCB designers account for when using SQT-138-01-F-D?
The connector body measures approximately 3.014 inches in length, 0.25 inches in depth, and 0.158 inches in breadth. Designers should reserve at least this footprint area on the PCB to accommodate the 76-position double-row socket layout.
