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: 1.5 mm. Top-entry through-hole mated example: 5.9 mm height and 3.5 mm depth.
Exact part, mate and contact
JST ZHR-4; mate B4B-ZR; contact SZH-003T-P0.5. Tool resource: AP-K2N / MKS-L / APLMK SZH003-05.
ZH connector catalogWhat 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.

Documented component path
Documented outcome: With ZHR-4 identified in the equipment documentation, use the named ZH catalog row to select B4B-ZR 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.
