A 5-pin, 1.25mm pitch housing from the A1251 series; requires mechanical verification for use as a GHR-05V-S replacement.
Finding a substitute for the JST GHR-05V-S, a 5-pin 1.25mm pitch housing, requires careful review. While many alternatives exist with similar electrical specs, the primary challenge is ensuring mechanical compatibility with the JST GH connector series.
High probability of mismatch in housing dimensions and locking mechanism.
Voltage and current ratings of similar connectors are typically sufficient.
1.25mm pitch connectors are widely available, but finding a true JST GH compatible is key.
There are no guaranteed direct replacements for GHR-05V-S without verifying mechanical compatibility. Alternatives exist with the same pitch and pin count, but they often belong to different, incompatible connector families.
Source housings specifically listed as JST GH series compatible and verify with mechanical drawings and samples before production.
The main risk is mechanical incompatibility. The substitute may not mate correctly with the JST GH series PCB header, leading to connection failure.

| Feature / factor | GHR-05V-S | A1251H-5P | A1257H-5P | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Positions | 5 | 5 | 5 | 5 — Number of positions matches.; A1257H-5P: Number of positions matches. | |
| Pitch Mm | 1.25mm | 1.25mm | 1.25mm | 1.25mm — Connector pitch matches.; A1257H-5P: Connector pitch matches. | |
| Package | Housing | Housing | Housing | Housing — Both are receptacle housings.; A1257H-5P: Both are receptacle housings. | |
| Connector Family | JST GH Series | A1251 Series | Unknown (likely PicoBlade compatible) | A1251 Series / Unknown (likely PicoBlade compatible) — Target is JST GH series. Mechanical compatibility and locking mechanism must be verified.; A1257H-5P: Target is JST GH series. Mechanical compatibility and locking mechanism must be verified. | |
| Material | PBT | Nylon 66 | Nylon 66 | Nylon 66 — Material differs, check environmental/flammability needs.; A1257H-5P: Material differs, check environmental/flammability needs. |
The best alternatives for the GHR-05V-S are other 1.25mm 5-pin housings from the JST GH series or a verified compatible series. Candidates like CJT's A1257H-5P have similar specs but require mechanical verification.
