Repair identification example

JST PA: PAP-04V-S example

PA uses a secure latch and keyed housing; do not substitute PH because both are nominally 2.0 mm.

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-board cable housing and board header
  • Documented pitch: 2.0 mm. Standard housing example; retainer-compatible PARP is a separate selection.

Exact part, mate and contact

JST PAP-04V-S; mate B04B-PASK; contact SPHD-002T-P0.5. Tool resource: AP-K2N / MKS-L-10 / APLMK SPHD002-05.

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 PAP-04V-S identified in the equipment documentation, use the named PA catalog row to select B04B-PASK 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.
