Is there a pin-compatible replacement for DZ254R-11-02-63?

While connectors with the same 2.54mm pitch and 2-pin straight layout exist, no direct pin-compatible replacements with a matching 500V rating and gold plating were found in this review. Alternatives require compromising on electrical specifications.

What risks should I check before replacing DZ254R-11-02-63?

Before replacing, you must verify your circuit's maximum voltage is safely below the alternative's 250V rating. Also, confirm if tin plating is acceptable for your application's contact reliability, mating cycles, and environmental conditions, as it is a downgrade from gold.

Finding a substitute for the DZ254R-11-02-63 header requires careful attention to its high 500V rating and gold-plated contacts. While form-factor matches are common, most alternatives offer lower electrical performance, necessitating a thorough review for your specific application.

AI replacement insight

Electrical riskhigh

Candidate voltage rating is 50% lower than target. Unsuitable for high-voltage applications.

Package risklow

Form factor (2-pin, 2.54mm straight header) is standard and matches are available.

Sourcing riskmedium

Finding a match with 500V rating and gold plating may require searching outside common catalog parts.

Can it be replaced directly?

No direct, drop-in replacement was found. Available alternatives have a significantly lower voltage rating (250V vs 500V) and use tin plating instead of gold, requiring careful engineering review.

Best replacement path
