Strong functional match with same voltage and plating, but requires mechanical verification.
Find and compare substitutes for the ZHOURI PZ2.54-1x4-11.2, a 4-pin 2.54mm pitch straight header. Key considerations for alternatives include voltage rating, operating temperature, and contact plating.
Mechanical dimensions are unverified for all candidates and critical for connectors.
Many alternatives have much lower voltage and temperature ratings.
No direct pin-to-pin replacement has been verified. XDZ254-1-04-Z-2.5-G1 is the closest candidate, but requires engineering review of its datasheet for mechanical fit.
XDZ254-1-04-Z-2.5-G1 is the strongest functional match but requires verification of mechanical dimensions and a minor temperature difference.
The main risks are mechanical incompatibility and significant downgrades in voltage rating and operating temperature with most alternatives.

| Feature / factor | PZ2.54-1x4-11.2 | XDZ254-1-04-Z-2.5-G1 | XY-XH2.54-4A11-R | ZX-XH2.54-4PZZ-R | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 1x4 Pin Header, 2.54mm Pitch | Through Hole, Straight | Through Hole, Straight | Through Hole | Through Hole, Straight — Form matches, but mechanical dimensions require verification.; XY-XH2.54-4A11-R: Form matches, but mechanical dimensions require verification.; ZX-XH2.54-4PZZ-R: Straight header, but mechanical dimensions require verification. |
| Current | 2.5 A | 3.0 A | - | - | 3.0 A — Higher current rating is a safe upgrade. |
| Voltage | 1000 V AC | 1000V AC | 250 V | 250 V | 1000V AC / 250 V — Withstand voltage matches target.; XY-XH2.54-4A11-R: Significantly lower voltage rating.; ZX-XH2.54-4PZZ-R: Significantly lower voltage rating. |
| Temperature | -45°C to +105°C | -40°C to +105°C | -25°C to 85°C | -25°C to +85°C | -40°C to +105°C / -25°C to 85°C / -25°C to +85°C — Slightly narrower range at low end.; XY-XH2.54-4A11-R: Significantly narrower operating temperature range.; ZX-XH2.54-4PZZ-R: Significantly narrower operating temperature range. |
| Plating | Gold over Nickel | Gold | Tin (inferred) | Tin (inferred) | Gold / Tin (inferred) — Contact plating material matches.; XY-XH2.54-4A11-R: Likely tin-plated, a downgrade from gold.; ZX-XH2.54-4PZZ-R: Likely tin-plated, a downgrade from gold. |
The best alternative found is XDZ254-1-04-Z-2.5-G1 from XUNDA. It matches the target's key specs like gold plating and 1000V withstand voltage, but requires mechanical verification before use.
