JST XH wire-to-board connector family
JST XH is a nominal 2.5 mm pitch, single-row wire-to-board series with shrouded headers and friction-lock mating parts.
Also called JST XH XHP housing XH series 2.5mm 2.5 mm XH connector
Use the exact XHP designation. Ordinary XH and specially spaced, reduced-population variants must not be conflated.
Look for
Search the maker’s part number (for example an XHP housing series) and verify the shroud, mating direction and position count.

Does every XH part use the ordinary populated spacing?
No. XH has a nominal 2.5 mm family pitch, but the catalog also identifies reduced-population XHP-2(10.0)-U and XHP-6(5.0)-U variants. The full designation and occupied-position arrangement matter, not just the family nickname. C350A · C350D
| Check | Documented distinction | Boundary |
|---|---|---|
| Ordinary family description | JST describes the XH family as nominal 2.5 mm and single row. C350A | Keep the manufacturer’s value; a generic seller label is not a substitute for the exact catalog row. |
| Named four-circuit housing | XHP-4 is listed as a four-circuit cable housing. C350C | Its housing drawing is not the board-header footprint. |
| Named reduced-population variants | XHP-2(10.0)-U and XHP-6(5.0)-U are documented at 10.0 mm and 5.0 mm respectively. C350D | These values belong to those specifically named exceptions, not every XH housing. |
| The opposite component | The XH family includes top/side entry and through-hole/SMT header choices. C350B · C350D | Occupied positions, entry direction, header identity and device wiring remain separate checks. |
- What the evidence supports
- XHP-4 is a documented four-circuit housing; the catalog separately identifies special XHP variants.
- What not to conclude
- A family nickname alone does not establish populated positions or a device cable’s wiring.
- Keep this check open
- Exact header, circuit population and board footprint are unresolved until the part is identified.
Keep this limit: Do not stretch the ordinary family description over the reduced-population examples. Matching the number of wires is not evidence of matching positions, header geometry or wiring. C350C · C350D
Before you choose a part
- Write the full housing suffix rather than just “XH”.
- Read the circuit-count and reduced-population row when relevant.
- Confirm the exact mating header and contacts.

What this view supports
- A taller housing elevation with pronounced side retention rails
- The XH name does not make every reduced-population variant a 2.5 mm arrangement
What remains unknown
Separate art panels are independently fitted. The illustration is not a PH/XH size ruler or mating-face drawing.
The next useful check
Verify the ordering code and manufacturer table, then identify the corresponding header and terminals.

REPAIR FIELD NOTES / Small wire-to-board series
First verify the exact manufacturer series
XH is not simply another name for PH
JST documents XH as a nominal 2.5 mm pitch series and PH as nominal 2.0 mm. Both have common shrouded friction-lock implementations, but they are distinct manufacturer-defined identities. Confirm header, housing and contact numbers rather than forcing close-looking parts.
Avoid: Believing a nominal pitch difference can be compensated by pressure, bending contacts or hand modification.
Full source-scoped reading and three practical checks ↗The board entry direction changes the repair task
No. JST’s XH family lists top-entry and side-entry mounting variants, with through-hole and surface-mount choices. The series name narrows the family, but you still need an exact header number, board orientation, housing style and clearance check.
Avoid: Ordering any part called XH with the same number of contacts can yield the wrong mounting orientation.

These notes add editorial context to the original canonical reference; they do not change its claim IDs or prove mating, wiring or polarity.

A boundary, not an omission to guess around.
Isolate all power and inspect the part code on the housing or board documentation. Compare the exact XH housing and approved mating header variant, not only a rough ruler measurement. Confirm the circuit assignment and allowable application from the equipment maker before reusing a cable.
Before you connect
What to check
- Isolate all power and inspect the part code on the housing or board documentation.
- Compare the exact XH housing and approved mating header variant, not only a rough ruler measurement.
- Confirm the circuit assignment and allowable application from the equipment maker before reusing a cable.
Important boundary
This reference establishes only the specific manufacturer-documented family and example noted in the sources. It does not verify an arbitrary mating pair, cable orientation, electrical rating or device combination. Stop and consult original documents for the exact products.
