Frequently Asked Questions

Question: Is this connector compatible with standard 3.5mm headphones?
Answer: Yes, it accepts industry-standard 3.5mm (1/8″) stereo mini plugs used in most headphones and audio cables.

Question: What does “TRS” mean in the signal lines?
Answer: TRS stands for Tip-Ring-Sleeve, indicating separate conductors for left audio (tip), right audio (ring), and common ground (sleeve) in a stereo configuration.

Question: Can this jack detect when a plug is inserted?
Answer: Yes, its integrated single switch activates upon plug insertion, useful for muting speakers or switching audio sources.

Question: Why choose an obsolete part?
Answer: Obsolete parts remain essential for legacy product repairs or long-lifecycle designs. PCX sources genuine end-of-life components to support ongoing production needs.

Question: Is the gold plating on contacts significant?
Answer: Absolutely. Gold plating resists corrosion and ensures stable, low-resistance connections over thousands of mating cycles, critical for audio clarity.

Question: How is this connector mounted?
Answer: It uses through-hole technology (THT) – pins are inserted into PCB holes and soldered for a strong mechanical and electrical bond.
