USB-A Receptacle for Panel-Mount and Edge-Card Applications
The Amphenol FCI 73725-0110BLF is a 4-contact USB-A (USB Type-A) receptacle from the 73725 series, designed for USB 2.0 signal and power delivery. It is a right-angle, through-hole mount connector with a shielded copper alloy shell and board locks for mechanical retention during soldering and against cable insertion forces.
What the 2.5 A Rating and 1500 Mating Cycles Mean for Your Design
For USB 2.0 standard downstream ports (SDP) that negotiate 500 mA, this connector runs well below its thermal ceiling. If you are using it for a dedicated charging port (DCP) or a proprietary power profile, the 2.5 A rating gives you margin for 5 V at 2.5 A (12.5 W) through the VBUS and GND pins — but the USB 2.0 signaling spec does not define data transfer above 480 Mbps, so this is not a USB 3.0 connector despite the physical Type-A form factor. This makes the 73725-0110BLF a better fit for field-serviceable equipment where the cable is plugged and unplugged daily over several years.
Board Lock and Right-Angle Mounting — Mechanical Fit
The UL94 V-0 flammability rating means the housing material stops burning within 10 seconds after ignition — required for equipment installed inside enclosures that must meet IEC 60950-1 or UL 62368-1 safety standards. This combination of wide temperature tolerance and flame rating makes the connector suitable for non-consumer applications where reliability and safety certification matter.
Packaging Variant — Tube vs Tape & Reel
The 73725-0110BLF ships in a Tube. The functional equivalent 73725-0110RLF is identical in every spec — same 4 contacts, right-angle through-hole, gold/GXT plating, 1500 cycles, shielded shell, board locks — but packaged in Tape & Reel (TR) and Cut Tape (CT) for automated pick-and-place assembly. If your line uses tube-fed insertion, the -0110BLF is the correct order code. For reel-fed machines, specify the -0110RLF variant. There is no electrical or mechanical difference between the two.
