H12WD4825P Equivalent & Substitute Parts

Part Overview

The H12WD4825P is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) device in a hockey puck form factor. This component is designed for AC load switching applications with zero-cross detection, operating at 25A load current across a 48V to 660V range. The device accepts 4–32VDC input control signals and features screw terminal connections for both control and load circuits.

The H12WD4825P maintains Active product status with 733 units currently in stock. Finding equivalent or substitute parts becomes necessary when addressing supply chain constraints, regional availability limitations, or procurement preferences while maintaining identical electrical and mechanical performance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the H12WD4825P is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Type: AC switching with zero-cross detection
• Input Voltage Range: 4–32 VDC control signal
• Load Voltage Range: 48–660 V AC
• Load Current Rating: 25 A
• Mounting Type: Chassis Mount
• Termination Style: Screw Terminal
• Package Form Factor: Hockey Puck
• Regulatory Compliance: RoHS Compliant

The substitute part 84137110N (Crouzet, GN series) meets all specified electrical and mechanical parameters, enabling direct functional replacement in applications requiring identical switching characteristics and physical installation constraints.

Parameter Comparison

Selection between these parts should be based on procurement lead times, supplier relationships, and regional distribution channels. Both components satisfy identical functional requirements for AC load switching applications within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can the 84137110N directly replace the H12WD4825P in existing designs?

A: Yes. Both components share identical electrical specifications (SPST-NO configuration, 4–32VDC input, 48–660V load range, 25A current rating) and mechanical form factor (hockey puck, screw terminal, chassis mount). No circuit modifications are required.

Q: Are there differences in packaging between these parts?

A: The H12WD4825P is supplied in Bulk packaging, while the 84137110N is supplied in Box packaging. Both contain the same component; packaging differences do not affect electrical or mechanical compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the H12WD4825P and 84137110N are RoHS Compliant with MSL rating of 1 (Unlimited). Both carry ECCN classification EAR99 and HTSUS code 8536.49.0080. The 84137110N additionally carries REACH Unaffected status.

Q: What determines whether a part can substitute for the H12WD4825P?

A: Substitution requires exact equivalence across circuit configuration (SPST-NO), output type (AC with zero-cross), input voltage (4–32VDC), load voltage (48–660V), current rating (25A), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck).

Q: Which part should be selected for new procurement?

A: Selection depends on supply availability and procurement preferences. The 84137110N currently shows higher inventory (1048 units versus 733 units). Both parts are Active products suitable for immediate deployment.
