Connectors, Interconnects

Connectors Interconnects covers the parts that join one circuit to another, from the AC inlet on a power supply chassis down to the tiny FFC connector holding a display ribbon in a handheld device. The category is broad. It includes AC power connectors, backplane and card edge types, banana and tip jacks for test benches, barrel power jacks, coaxial RF connectors, D-sub shells, circular connectors for industrial and mil-spec gear, fiber optic termini, board-to-board mezzanine parts, and between-series adapters for mating dissimilar interfaces. Nearly every assembled product contains several of these, and they show up in telecom racks, medical equipment, automotive harnesses, instrumentation, and consumer electronics alike. Buyers sourcing connectors tend to check a few things before anything else: mating cycle rating, contact plating (gold flash versus 30 microinch gold changes both price and life), current and voltage ratings per contact, wire gauge range, and the exact keying or polarization code, since one wrong suffix can mean a housing that looks right but will not mate. Pitch and footprint matter for board-level parts, and RF types add impedance and frequency range to the checklist. The real trade-off in this category is usually lead time against price. Franchised stock on popular TE, Molex, or Amphenol series can carry 12 to 20 week factory lead times when demand spikes, so many buyers turn to independent channels for shortages. That is where counterfeit risk creeps in, especially on high-value circular and mil-spec connectors, and it is worth asking for traceability and photos of labels and date codes before committing. Packaging preference matters too: cut tape versus full reel, or bagged versus tray, affects both price and how the parts run through your assembly process.

Frequently Asked Questions

How do I make sure the connectors I buy from an independent distributor are not counterfeit?

Ask for full traceability paperwork, lot and date codes, and clear photos of the actual parts and labels before payment. Reputable independent distributors will also support third-party testing such as XRF plating analysis and decapsulation on higher-value parts. If a price is far below market on a shortage part, treat that as a warning sign.

The part number I need shows a long factory lead time. What are my options?

First check whether a different suffix of the same series (plating, keying, or packaging variant) is in stock, since those are often interchangeable for your build. Independent distributors frequently hold franchised excess or factory overruns on constrained series, so sending your full BOM for a shortage quote is usually faster than waiting on the standard lead time.

Does gold plating thickness actually matter when I select a connector?

Yes. Gold flash is fine for a few dozen mating cycles in a controlled environment, but connectors rated for hundreds of cycles typically specify 15 to 30 microinches of gold over nickel. Thinner plating saves cost but wears through to the base metal, which raises contact resistance and causes intermittent failures over time, especially in humid or high-vibration environments.
