H12WD4825G-10 Equivalent & Substitute Parts

Part Overview

The H12WD4825G-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component functions as an AC output relay with a 25A load capacity and operates with a 4–32VDC input signal. The part is currently active in production and RoHS compliant. Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or specific regional availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the H12WD4825G-10 is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be maintained
• Output Type: AC output operation required
• Input Voltage Range: 4–32VDC control signal compatibility
• Load Current Rating: 25A minimum capacity
• Package Type: Hockey puck form factor for mechanical fit
• Termination: Screw terminal connection standard
• Mounting: Chassis mount orientation

The substitute part 84137210N (Crouzet GN series) maintains functional equivalence in circuit topology, input voltage range, load current rating, package form factor, and termination style. The primary difference is the load voltage range specification (24–280V versus 48–660V), which defines the application envelope for each part.

Parameter Comparison

Engineering Selection Recommendations

Both the H12WD4825G-10 and 84137210N are active production components with RoHS compliance certification. Selection between these parts is determined by load voltage requirements:

• H12WD4825G-10: Select for applications requiring load voltage operation within the 48–660V range
• 84137210N: Select for applications requiring load voltage operation within the 24–280V range

Both parts share identical input voltage control range (4–32VDC), load current capacity (25A), circuit topology (SPST-NO), package form factor (hockey puck), and termination method (screw terminal). Component selection must align with the specific load voltage specification of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 84137210N substitute for the H12WD4825G-10 in all applications?

A: Substitution is valid only when the application load voltage operates within the 24–280V range specified for the 84137210N. Applications requiring load voltages above 280V or below 24V must use the H12WD4825G-10 (48–660V range).

Q: Are the input control voltage requirements identical?

A: Yes. Both parts operate with a 4–32VDC input signal range and are functionally equivalent in control circuit design.

Q: Do both parts use the same package and mounting configuration?

A: Yes. Both the H12WD4825G-10 and 84137210N use hockey puck packaging with chassis mount orientation and screw terminal connections, ensuring mechanical and electrical interface compatibility.

Q: What is the load current capacity for both parts?

A: Both parts are rated for 25A load current operation.

Q: Are both parts RoHS compliant?

A: Yes. Both the H12WD4825G-10 and 84137210N meet RoHS compliance requirements.

Q: What is the primary difference between these two parts?

A: The primary difference is the maximum load voltage specification. The H12WD4825G-10 supports 48–660V, while the 84137210N supports 24–280V. All other electrical and mechanical parameters are equivalent.
