Is there a pin-compatible replacement for HC-PA-3A?

Yes, connectors like WF-1A200A3P are pin-compatible in terms of form factor (3-pin, 2.0mm pitch, straight). However, they are not electrically equivalent due to a lower current rating.

What risks should I check before replacing HC-PA-3A?

The most critical risk is the current rating. Ensure your application's maximum current draw is safely below the 2A rating of the replacement, as the original part was rated for 3A.

HC-PA-3A Alternatives, Datasheet & Cross Reference | HCTL

Finding a substitute for the HCTL HC-PA-3A 3-pin header requires checking the current rating. While many 2.0mm pitch headers are form-compatible, the target's 3A rating is higher than many common alternatives.

AI replacement insight

Electrical riskhigh

Most alternatives have a lower 2A current rating, posing a fire or failure hazard if the application draws more than 2A.

Package risklow

Many 2.0mm pitch, 3-pin straight headers are mechanically compatible.

Can it be replaced directly?

No direct, drop-in replacement with a matching 3A current rating was found among the candidates. All form-compatible options have a lower 2A rating.

Best replacement path

Seek a 3A-rated, 2.0mm pitch, 3-pin straight header. If unavailable, consider alternatives like WF-1A200A3P but verify the 2A rating is acceptable for the application.

Main risk

The primary risk is electrical overstress due to the lower current rating (2A) of most alternatives compared to the target's 3A rating.

Recommended alternatives

An Active, form-compatible 3-pin header from HANBO, but with a lower 2.0A current rating that requires engineering validation.
