H12WD4825-10 Equivalent & Substitute Parts

Part Overview

The H12WD4825-10 is a solid state relay (SSR) manufactured by Sensata Technologies, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is designed for AC load switching applications with a 25 A capacity and operates with input control voltages between 4 and 32 VDC. The device is currently in active production status and carries RoHS compliance certification.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters, including circuit configuration, load current rating, input voltage range, output voltage range, termination style, and physical package form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H12WD4825-10 is determined by the following critical parameters:

• Circuit configuration must be SPST-NO (1 Form A)
• Load current rating must be 25 A
• Input voltage range must support 4 ~ 32 VDC operation
• Output type must be AC
• Package form factor must be hockey puck
• Termination style must be screw terminal
• Mounting type must be chassis mount

The load voltage range represents the maximum operating envelope for the relay. Substitute parts with a lower maximum load voltage (such as 24 V ~ 280 V versus 48 V ~ 660 V) remain functionally compatible when the actual application load voltage falls within the substitute part's specified range. The substitute part 84137210N meets all critical compatibility criteria while operating within a narrower load voltage specification.

Parameter Comparison

Engineering Selection Recommendations

Both the H12WD4825-10 and 84137210N are active production components with RoHS compliance certification. Selection between these parts is determined by application load voltage requirements. The H12WD4825-10 supports load voltages up to 660 V, while the 84137210N is rated for load voltages up to 280 V. For applications requiring load voltage operation above 280 V, the H12WD4825-10 is the appropriate selection. For applications with load voltages within the 24 V to 280 V range, either component is electrically compatible.

Frequently Asked Questions (FAQ)

Q: Can the 84137210N replace the H12WD4825-10 in all applications?

A: The 84137210N is compatible only when the application load voltage does not exceed 280 V. If your application requires load voltages between 280 V and 660 V, the H12WD4825-10 must be used.

Q: Are the input control voltage ranges identical between these parts?

A: Yes. Both the H12WD4825-10 and 84137210N operate with input control voltages between 4 and 32 VDC.

Q: Do both parts have the same load current capacity?

A: Yes. Both components are rated for 25 A load current.

Q: Are the physical packages interchangeable?

A: Yes. Both parts use the hockey puck package form factor with screw terminal connections and chassis mount configuration.

Q: What is the significance of the different load voltage ranges?

A: The load voltage range defines the maximum AC voltage that can be switched by the relay. The H12WD4825-10 accommodates higher voltage applications (up to 660 V), while the 84137210N is suitable for lower voltage applications (up to 280 V). Selection depends on your specific load voltage requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the H12WD4825-10 and 84137210N meet RoHS compliance requirements.
