Frequently Asked Questions
Q: What is the difference between the DIP and SMD versions of these audio jack connectors?
A: DIP (Dual In-line Package / Through-Hole) connectors have pins that pass through holes in the PCB and are soldered on the underside — great for hand-soldering and prototyping. SMD (Surface-Mount Device) connectors are soldered directly onto pads on the surface of the board, making them ideal for compact designs and automated PCB assembly processes.
Q: Which series should I choose — PJ-242, PJ-301M, PJ-313E, PJ-320D, PJ-327A, PJ-391, PJ-392, or PJ-393?
A: Each series corresponds to a different physical footprint, pin configuration, and body style. Check your PCB layout or datasheet for the exact series number required. Common choices include the PJ-301M for standard vertical 3.5mm through-hole mounting and the PJ-320D for a low-profile horizontal SMD design. Select based on your board's footprint dimensions and mounting orientation.
Q: Are these audio jack sockets compatible with standard 3.5mm headphone and aux plugs?
A: Yes. The 3.5mm variants are fully compatible with standard TRS and TRRS headphone, microphone, and auxiliary audio plugs used in everyday consumer electronics. The 2.5mm variants suit smaller-form-factor devices and specialty audio applications that use the 2.5mm standard.
