H12WD4875G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The H12WD4875G 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 is designed for AC load switching applications with zero-cross detection, operating from 4-32VDC input control voltage and supporting loads up to 75A at 48-660V. The part is currently Active in product status with full RoHS compliance. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or application-specific packaging preferences.

Substitute Part Grouping Explanation

Substitution eligibility for the H12WD4875G is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must support AC with Zero Cross detection for synchronized load switching
• Input Voltage Range: Must accommodate 4-32VDC control signal
• Load Voltage Range: Must support 48-660V AC load operation
• Load Current Rating: Must be rated for 75A continuous operation
• Package Type: Must be Hockey Puck form factor for mechanical compatibility
• Mounting Type: Must support Chassis Mount installation
• Termination Style: Must use Screw Terminal connections
• Compliance: Must maintain RoHS compliance status

The substitute part 84137130N (Crouzet, Series GN) meets all specified electrical and mechanical parameters, making it a direct functional equivalent for applications requiring the H12WD4875G.

Parameter Comparison

Engineering Selection Recommendations

Both the H12WD4875G and 84137130N are Active products with full RoHS compliance and identical MSL ratings. Selection between these parts should be based on:

• Availability: H12WD4875G has 926 units in stock; 84137130N has 932 units in stock
• Packaging Format: H12WD4875G supplied in Bulk packaging; 84137130N supplied in Box packaging
• Manufacturer Preference: H12WD4875G (Sensata-Crydom, Series H12WD) versus 84137130N (Crouzet, Series GN)
• Regulatory Requirements: Both parts maintain equivalent ECCN and HTSUS classifications

No electrical or mechanical performance differences exist between these parts for the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can the 84137130N replace the H12WD4875G in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: SPST-NO circuit configuration, 75A load current, 4-32VDC input, 48-660V load voltage, AC zero-cross output, Hockey Puck package, Chassis Mount, and Screw Terminal termination.

Q: Are there differences in compliance or certifications?

A: Both parts are RoHS Compliant with MSL 1 (Unlimited) ratings. Both carry EAR99 ECCN classification. No compliance differences exist.

Q: What is the difference between Bulk and Box packaging?

A: Packaging format does not affect electrical or mechanical performance. Bulk packaging typically indicates loose component supply, while Box packaging indicates organized container supply. Selection depends on inventory management and handling requirements.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the application requires SPST-NO switching topology, 75A load current capacity, 4-32VDC control input, and 48-660V AC load voltage operation. Both parts meet these specifications identically.

Q: Are there any known compatibility issues between manufacturers?

A: No compatibility issues are indicated in the provided specifications. Both parts use identical termination style (Screw Terminal), mounting type (Chassis Mount), and package form factor (Hockey Puck).
