It carries 37 female sockets across two rows in the standard DC (C) shell size — the same footprint as a DB-37 but with the press-fit compliant pin that eliminates the thermal cycle of wave soldering. ## What the Press-Fit Termination and Board Locks Mean on the Board The board locks are integral to the shell and snap into the board, taking the insertion and extraction forces off the signal pins. This combination is common in backplane and high-reliability assemblies where thermal stress from soldering is a concern. ## Current, Voltage, and Temperature Range The operating range spans -55°C to 125°C, so the connector holds up in automotive underhood and unheated industrial cabinets. The difference is termination: the D37S91C4GX00LF uses press-fit pins, while the D37S24A4GX00LF uses solder tails.","metaTitle":"Amphenol FCI D37S91C4GX00LF Delta D D-Sub Receptacle, 37 Pos","metaDescription":"Amphenol FCI Delta D D-Sub receptacle, 37 positions, press-fit termination, gold flash contacts, board locks, UL94 V-0. 5 A per contact, 300 V.
