LinkScope Sourcing 40

PCB connector suppliers

LinkScope Sourcing 40 helps a US business buyer write one brief and ask factories for quotes on the same board-connector configuration. The desk does not own a factory, does not hold stock, and does not assign a verified grade to a maker.

What the brief has to lock before names are compared

A family label such as header, receptacle, or wire housing is a starting filter. It does not prove that two drawings mate. Each card below is a question the proposed supplier should answer for the exact model.

Pitch and contacts

State pitch in inches and millimeters. A 0.100 inch row is 2.54 mm center to center. Contact count, row count, and whether the shroud is open or boxed change the footprint even when the pitch matches.

Termination

Separate solder tail, press-fit, and crimp. Tail length, PCB thickness, and whether the joint is a through-hole fillet or a surface-mount pad belong in the quote, not in a later email.

Plating and mating

Ask for plating stack and thickness, for example tin, or gold at 15 µin or 30 µin over nickel, plus the connector mating cycle the datasheet uses. A higher cycle count is a document claim until the test method is named.

Environment

Ingress protection, operating temperature, and whether the housing is sealed are separate lines. An unsealed 2.54 mm header and a gasketed housing are not interchangeable because both touch a printed board.

Measured lines inside this connector family

These rows follow the measured terms assigned to this site. Search volume is not copied onto the page as a traffic forecast. Each row is a procurement path, not a catalog of owned parts.

Waterproof pcb connector

Use this path when the housing must keep water out. Record the IEC 60529 code the drawing cites. IP67, in the standard text, means dust tight and a temporary immersion of 1 m for 30 minutes. The supplier still has to show that code on the named housing.

Open the inquiry list

Pcb connector 01 inch

Use this path when the footprint is the 0.100 inch grid. Confirm single-row or dual-row, pin length above the board, and whether the mate is a crimp housing or a board-to-board socket.

Build the quote checklist

5 pin pcb connector plug

Use this path when the cable side is a five-contact plug. Pinout, keying, and current per contact decide whether a lookalike plug is usable on the host board.

Map the project use

Welding pcb connector

The phrase can mean a soldered termination, a welded contact, or a connector on welding equipment. The quick spec brief forces that choice into the open before an alternate part is accepted.

Hand off the open points

Questions buyers ask before the first factory reply

Does a matching pitch mean the parts mate?

No. Pitch is one dimension. Contact gender, row spacing, latch, polarization rib, and PCB tail style can still block mating. Ask each factory to mark deviations against your drawing or pin table.

Where do current and voltage come from?

They come from the datasheet of the exact part, usually with a stated temperature rise such as 20°C or 30°C and a stated ambient. This site does not publish a universal ampere rating for the family.

What evidence is reasonable to request?

A current datasheet, a footprint drawing, plating callout, and the test method behind connector mating cycle or ingress protection. TIA-568 is a cabling reference for premise wiring questions. It is not an approval stamp for a board header.

How should a target budget be written?

Give an amount or a range, a currency, and whether the figure is per unit or for the whole order. Freight, duty, tooling, and plating upcharges stay outside that figure until a quote lists them. High-end, mid-range, budget, or undecided is your preference, not a factory score.

OEM-coded footprint or a compatible outline?

An OEM-coded header can follow the host maker support text more directly. A compatible outline can widen the factory list when pinout, pitch, and latch are checked on the exact board. New stock and a refurbished or surplus header need separate columns because wear and traceability differ. This desk does not pick a side for you.

Compare quotes on one configuration

Normalize manufacturer, model, pitch, contact count, termination, plating, quantity, currency, Incoterm, and destination before you read unit price. A lower unit price with a different gold thickness or a missing latch is a different purchase.

Sourcing scenario: a buyer has a dual-row 2.54 mm header on a rack card and a single-row quote in reply. Background is a drop-in repair. Process is to reject the quote or relabel it as an alternate. Result is a comparison sheet that does not mix the two footprints.
