Exact part and mate

PHR-4 housing and B4B-PH-K-S board header

JST’s PH catalog lists PHR-4, B4B-PH-K-S and SPH-002T-P0.5S as the same 4-circuit connector ecosystem. Select the complete designation and terminal; pitch alone does not establish a mate.

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

  • 2.0 mm
  • friction lock
  • Cable housing and board footprint are different component roles.

Exact component and mating role

JST PH PHR-4: cable housing for receptacle contacts; 4 positions. Documented mate: B4B-PH-K-S, top-entry board header. pp.2–3: same-series housing/header rows and assembly layout

Contacts, accessories and tools

Selected contacts: SPH-002T-P0.5S

No separate retainer or backshell selected for this example.

SPH-002T-P0.5S: AP-K2N / MKS-L; crimp applicator with dies APLMK SPH002-05S. These are catalog resources, not an instruction to fabricate a repair harness.

Choose the right drawing

Use the linked PH catalog pp.2–3 for housing/header identity and contact/tool choice; use the exact manufacturer part drawing and current handling instructions for geometry and assembly.

Worked documentary examples

Documented evidence state

Documented outcome: The selected 4-circuit PH housing/header rows and named terminal are documented together.

    Conflict evidence state

    Documented outcome: A different family, count or keyed suffix does not inherit this relationship.

      Missing evidence state

      Documented outcome: Without the equipment-approved part and wiring, this is an identity candidate rather than a replacement approval.
