Is there a pin-compatible replacement for HCZZ0494-6?

No pin-compatible replacement has been confirmed. While some parts have the same pin count, pitch, and mounting style, differences in the connector housing and series (e.g., GH vs. PicoBlade) prevent a guaranteed fit without datasheet review.

What risks should I check before replacing HCZZ0494-6?

The main risk is mechanical. You must verify the PCB footprint, connector height, housing dimensions, and compatibility with the mating connector. Electrical ratings like voltage and current are generally similar or better in potential alternatives.

HCZZ0494-6 Alternatives, Datasheet & Cross Reference | Shenzhen Hongcheng Electronics Co., Ltd.

HCZZ0494-6 is a 6-pin, 1.25mm pitch vertical SMT header. Finding a direct replacement requires careful verification of mechanical dimensions and series compatibility, as parts with similar specs may not mate correctly.

AI replacement insight

Package riskhigh

Different connector series (GH vs PicoBlade) are not typically inter-mateable.

Electrical risklow

Candidates have matching or superior voltage/current ratings.

Can it be replaced directly?

No direct, verified pin-to-pin replacement has been identified. All candidates require mechanical verification due to differences in connector series or form factor.

Best replacement path

Search for vertical SMT headers in the 'GH 1.25mm' series. Alternatives from different series like PicoBlade require mechanical drawing comparison.

Main risk

The primary risk is mechanical incompatibility. Connectors with the same pitch and pin count can have different housing shapes, locking mechanisms, and PCB footprints.

Recommended alternatives

A 6-pin, 1.25mm pitch vertical SMT header with similar electricals, but mechanical compatibility requires verification.
