Genuine Icom PCB-Mount 3.5mm Stereo Audio Jack
The Icom 6450002810 is a professional-grade right-angle 3.5mm audio jack connector designated C1FYE3-500-R, designed for use in multiple Icom transceiver models including the IC-706, IC-703, IC-7300, and IC-M803. This PCB-mount component provides the physical and electrical interface for connecting headphones, external speakers, audio accessories, or other equipment using standard 3.5mm stereo plugs. The right-angle configuration allows the connector to mount flat against the circuit board while positioning the jack opening parallel to the front or rear panel, optimizing space utilization in compact radio designs. The molded plastic housing ensures durability through thousands of plug insertion and removal cycles.

Application and Installation Notes
This audio jack serves as the primary interface for connecting headphones or external audio devices to Icom transceivers, providing convenient audio monitoring during radio operation. The integrated switching mechanism typically includes normally-closed contacts that route audio to the internal speaker when no plug is inserted, automatically disconnecting the speaker and routing audio to the jack when a headphone plug is inserted. This automatic switching eliminates the need for manual speaker disconnection and prevents audio feedback or acoustic coupling when using headphones. The right-angle design allows the jack to mount directly to the main circuit board while positioning the opening to align with a corresponding hole in the radio's front or rear panel.
Professional installation by qualified radio technicians is essential for this component. Access the appropriate circuit board following Icom service manual procedures, carefully disassembling the radio housing and removing any panels or components blocking access to the audio jack location. Desolder all five pins of the original jack using a desoldering pump, solder wick, or desoldering station, taking care not to overheat the PCB or damage surrounding components. Remove the old jack and thoroughly clean all mounting holes to remove residual solder. Insert the new C1FYE3-500-R jack with proper orientation, ensuring all five pins align correctly with their PCB holes and that the jack barrel aligns with the panel opening. Solder each pin securely, using appropriate soldering technique to create reliable joints without cold solder or bridges between adjacent pins.
After installation, verify proper mechanical and electrical function before reassembling the radio. Test jack insertion with a standard 3.5mm plug to confirm smooth insertion and positive retention. Verify that audio routes correctly to both the internal speaker (when no plug inserted) and through the jack (when plug inserted), and that the automatic speaker switching operates properly. Check for any audio distortion, intermittent connections, or noise that might indicate poor solder joints or contamination in the jack contacts. Ensure the jack aligns properly with the panel opening and that the plug can be inserted fully without obstruction or binding.
This audio jack should be replaced when troubleshooting symptoms including intermittent audio output, scratchy or noisy audio when moving the headphone plug, failure of automatic speaker switching, physical damage to the jack barrel, or loose mechanical attachment to the PCB. Worn contacts from repeated plug insertions can cause poor electrical connection, while physical damage to the plastic housing or jack barrel can prevent proper plug insertion or retention. Always use genuine Icom replacement parts to ensure proper contact arrangement, switching function, and mechanical fit with the radio panel.
Ideal for authorized Icom service centers, professional radio repair technicians, and experienced amateur radio operators with electronics repair skills maintaining IC-706, IC-703, IC-7300, or IC-M803 transceivers used in amateur radio, marine communications, or emergency communications applications.
