Repair identification example

JST PAL: PALR-04V example

PAL is the wire-to-wire series documented to mate with PA. Distinguish PAL contacts from PA contacts and choose the retainer for the exact housing.

Applies to: Documented component examples for identification and document selection. Exact equipment wiring, replacement suitability and powered use require the equipment maker’s documentation.

What the path requires

  • wire-to-wire housing ecosystem
  • Documented pitch: 2.0 mm. Wire-to-wire PAL housing example rather than a board footprint.

Exact part, mate and contact

JST PALR-04V; mate PAP-04V-S; contact SPAL-002T-P0.5. Tool resource: AP-K2N / MKS-L / APLMK SPAL002-05; PA side uses its own SPHD terminal..

PA family / PA and PAL connector catalog

What to observe

Count cavities and populated contacts separately.

Obtain a disconnected housing front and latch/termination side.

Measure a span across several pitch intervals; record the axis and uncertainty.

Worked documentary examples

Documented component path

Documented outcome: With PALR-04V identified in the equipment documentation, use the named PAL catalog row to select PAP-04V-S and the appropriate terminal. Check the source’s mounting/entry and wire criteria before proceeding.

    Missing exact evidence

    Documented outcome: If only pitch or wire count agrees, retain a family candidate and send the exact views, span/interval reading and markings to JST; no replacement is selected.

      Your next useful observation

      Compare the complete suffix, row arrangement, latch and entry direction against the manufacturer catalog.

      Keep these limits

      • Stop when the exact equipment part/wiring, opposing component or applicable terminal cannot be established.
      • Documented component examples for identification and document selection. Exact equipment wiring, replacement suitability and powered use require the equipment maker’s documentation.
