Five-contact wire plug next to a keyed board header

Project use, not a product family slogan

5 pin pcb connector plug

A five-contact plug is a pinout problem before it is a purchasing problem. LinkScope Sourcing 40 collects the host task, the documents, and the site limits so factories quote the same plug. This page does not claim the plug is stocked or approved for any network.

Pinout Key Current Delivery stage

From a job site back to a purchase line

Write the intended use in one sentence, then attach the constraints that a photo of a plug cannot show. The matrix is a buyer worksheet. Cells stay blank until a named part fills them.

UseWhat to confirmDocumentSite constraint
CPE or radio power leadWhich pin is positive, return, and senseHost schematic or pin tableIndoor cabinet versus outdoor enclosure
Rack card signalWhether any pair needs a stated impedanceBoard stack-up if impedance is requiredRight-angle versus vertical, and rack unit clearance
Field-replaceable sensorKeying so a 4-pin plug cannot enterMating drawing with polarizationGloves, latch force, and service access
Spare for a failed plugNew versus surplus, and remaining contact wearPhoto of the broken part plus pitch measurementWhether the board hole pattern is already soldered

Delivery stages worth separating

Ask for three stages instead of one lead-time word: document package, sample or first article, and production lot. Each stage can have its own quantity and its own timing request. A 7-day sample wish is not a production commitment, and this site will not convert it into one. Packing for a US destination, Incoterm, and who books freight belong on the production stage only.

Choices that look similar and are not

DisputeWhat to writeWhat the quote must name
Gold versus tinTin for fewer mating cycles and a lower metal cost. Gold when fretting or a higher cycle count is in the environment. Neither metal is universally correct.Thickness, such as 15 µin or 30 µin, and the underplate.
Sealed versus openOutdoor use may need an ingress code. IP67 in IEC 60529 means dust-tight construction and temporary immersion at 1 m for 30 minutes. An open friction-lock plug can be the right part inside a dry rack.The code tied to the quoted housing. A gasket forced onto an unsealed footprint changes the mate and the price.
Original versus compatibleA compatible plug can stand when the pinout, key, and latch match and the buyer accepts the deviation. It cannot stand when the host warranty forbids substitutes.New, refurbished, and surplus in separate columns. Surplus contacts can meet pitch and still fail a plating-wear check.
Pin tableNumber each contact and name the net: positive, return, sense, or unused. Leave frequency, insertion loss, return loss, and VSWR off this line unless the drawing calls the plug an RF path.The pin table, the key, and the plating thickness. A reply missing those is an incomplete alternate, not a lower price for the same plug.

Sourcing scenario: an outdoor radio uses a five-contact plug and the first quote is an unkeyed indoor header. Background is a tower-adjacent cabinet that sees rain on the cable entry. Process is to mark keying and the seal code as mandatory and to ask which pins carry current. Result is a revised quote that either shows the gasketed mate or is filed as a non-compliant alternate, not as a cheaper equivalent.

Reference boundary: TIA-568 can be cited when the plug lands on a twisted-pair plant and the buyer needs pair assignment language. The cabling overview is not a substitute for the current standard or for the connector drawing. FCC equipment rules apply to the finished radio if the buyer says they do. They are not a stamp on a loose plug.

Delivery questions that belong in the same email

  1. Is the price for the plug, the board header, or the mated pair?
  2. What is the sample quantity versus the production quantity, and which unit is pieces?
  3. Which Incoterm and which US destination does the freight line assume?
  4. Are partial shipments allowed, and who approves a plating or keying deviation?
  5. What evidence ships with the lot: datasheet revision, material callout, and any test sheet tied to that lot?

Put the five-pin brief in one request

Include pinout, keying, pitch, quantity, destination, and the stage you want priced first. A budget, if you have one, needs currency and a per-unit or whole-order basis.
