H12WD4890PGH Equivalent & Substitute Parts

Part Overview

The H12WD4890PGH is a solid-state relay (SSR) manufactured by Sensata-Crydom, designed for single-pole, single-throw normally open (SPST-NO) switching applications. This active product operates as a 1 Form A relay with zero-cross AC output capability, rated for 90 amperes at load voltages between 48V and 660V. The device features a hockey puck form factor with screw terminal connections and is suitable for chassis mount installations.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing while maintaining functional compatibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H12WD4890PGH is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Output Type: Must be AC with zero-cross capability
• Input Voltage Range: Must accommodate 4 ~ 32 VDC control signal
• Load Current Rating: Must support 90 A minimum
• Package Form Factor: Must be hockey puck configuration
• Termination: Must feature screw terminal connections
• Mounting: Must support chassis mount installation

The substitute part 84138150N (Crouzet GN+ series) meets these core functional requirements. The primary difference is the load voltage range specification: the substitute operates at 24 V ~ 500 V versus the main part's 48 V ~ 660 V range. This difference defines the substitution boundary and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the H12WD4890PGH and 84138150N are active products with RoHS compliance and unlimited moisture sensitivity ratings, making them suitable for production applications. The selection between these parts is determined by load voltage requirements:

• H12WD4890PGH: Select when load voltage operation extends above 500V or below 24V is not required
• 84138150N: Select when load voltage operation remains within the 24 V ~ 500 V range

Both parts share identical input voltage control ranges (4 ~ 32 VDC), load current capacity (90 A), circuit configuration (SPST-NO), output type (AC zero-cross), and physical form factor (hockey puck with screw terminals). The load voltage range difference is the sole technical distinction between these parts.

Frequently Asked Questions (FAQ)

Q: Can the 84138150N substitute for the H12WD4890PGH in all applications?

A: Substitution is valid only when the application load voltage remains within 24 V ~ 500 V. Applications requiring operation above 500V or below 24V require the H12WD4890PGH.

Q: Are the physical dimensions and mounting interfaces identical?

A: Both parts feature hockey puck form factor with chassis mount capability and screw terminal connections. Physical compatibility is maintained for direct replacement in existing designs.

Q: Do both parts support the same control input voltage?

A: Yes. Both the H12WD4890PGH and 84138150N accept 4 ~ 32 VDC input control signals.

Q: What is the significance of the zero-cross output type?

A: Zero-cross switching ensures the relay activates only when the AC load voltage crosses zero, reducing electromagnetic interference and extending component life in AC switching applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the H12WD4890PGH and 84138150N are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity).

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

A: Both parts are rated for 90 amperes continuous load current.
