Parts meeting all specified parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The PRD-5AY0-12 is classified as obsolete. The identified substitute PRD-5AY0-12 is a parametric equivalent with identical electrical, mechanical, and environmental specifications. This substitute maintains full compatibility with existing circuit designs and system requirements.

Both the main part and substitute are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. The substitute part is available with 823 pieces in new original stock condition.

Selection of the substitute part requires no design modifications, circuit re-evaluation, or thermal analysis, as all critical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: What makes PRD-5AY0-12 a direct substitute for itself?

A: The substitute PRD-5AY0-12 is identical to the main part across all specified electrical parameters (12VAC coil, 25A contact rating, SPDT form), mechanical specifications (chassis mount, screw terminal), and environmental ratings (-55°C ~ 45°C operating range). No parameter deviation exists.

Q: Are there any compatibility concerns when using the substitute?

A: No compatibility concerns exist. The substitute maintains identical coil voltage, contact form, current rating, switching voltage, and termination style. Direct pin-for-pin and functional replacement is supported without circuit modification.

Q: What is the significance of the ROHS3 compliance status?

A: ROHS3 compliance indicates the substitute part meets Restriction of Hazardous Substances Directive requirements, ensuring compliance with environmental and regulatory standards applicable to the original part.

Q: Does the MSL rating affect component handling?

A: The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints. The substitute part requires standard handling procedures without specialized moisture control measures.

Q: Can the substitute be used in the same mounting configuration?

A: Yes. Both the main part and substitute feature identical chassis mount configuration with screw terminal termination, enabling direct installation in existing mechanical assemblies without modification.

Q: What operational parameters remain consistent between the main part and substitute?

A: Operate time (40 ms), release time (20 ms), must operate voltage (10.2 VAC), must release voltage (1.2 VAC), coil current (820 mA), and coil resistance (3.2 Ohms) are identical, ensuring equivalent switching performance and circuit behavior.
