CJT
A 5-pin, 1.25mm pitch vertical SMT header with a higher voltage rating. Footprint verification is required.
HCZZ0494-5 is a 5-pin, 1.25mm pitch vertical SMT header. Alternatives exist but require careful verification of the PCB footprint to ensure mechanical compatibility.
PCB land pattern, connector height, and housing dimensions must be verified from datasheets.
Key electrical ratings (current, voltage) of top candidates match or exceed the target.
No direct, verified pin-to-pin replacement has been confirmed. Strong functional alternatives exist but require mechanical verification by an engineer.
Use a functional alternative like XD-1.25-5PLT after verifying its PCB footprint against the target's datasheet.
Mechanical footprint mismatch.

| Feature / factor | HCZZ0494-5 | A1251WV-S-5P | XD-1.25-5PLT | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SMT, Vertical | SMT, Vertical (180°) | SMT, Vertical | SMT, Vertical (180°) — Mounting type and orientation match.; XD-1.25-5PLT: Mounting type and orientation match. | |
| Pitch | 1.25mm | 1.25mm | 1.25mm | 1.25mm — Pin pitch is identical.; XD-1.25-5PLT: Pin pitch is identical. | |
| Voltage | 50V AC | 125V | 125V | 125V — Higher voltage rating provides more margin.; XD-1.25-5PLT: Higher voltage rating provides more margin. | |
| Current | 1.0A | 1A | 1A | 1A — Current rating is identical.; XD-1.25-5PLT: Current rating is identical. | |
| Pinout | See Datasheet | Unknown | Unknown | Unknown — PCB footprint must be verified from datasheet.; XD-1.25-5PLT: PCB footprint must be verified from datasheet. |
XD-1.25-5PLT and A1251WV-S-5P are strong functional alternatives with matching pitch, pin count, and higher voltage ratings. However, their PCB footprints must be verified against the HCZZ0494-5 datasheet before design-in.
