H12WD4890G-10 Equivalent & Substitute Parts

Part Overview

The H12WD4890G-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 rated load current of 90 A and operates with input control voltage between 4 and 32 VDC. The device is currently in active production status and is RoHS compliant. Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters while meeting the same regulatory and packaging requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the H12WD4890G-10 are qualified based on the following critical parameters that determine functional interchangeability:

• Circuit configuration: SPST-NO (1 Form A) topology
• Load current rating: 90 A minimum
• Input control voltage range: 4 ~ 32 VDC compatibility
• Output type: AC switching capability
• Package form factor: Hockey puck mechanical envelope
• Termination interface: Screw terminal connection
• Mounting orientation: Chassis mount compatibility
• Regulatory compliance: RoHS compliant status

The substitute part 84138150N from Crouzet meets these core requirements. However, the load voltage range differs: the substitute operates at 24 V ~ 500 V compared to the main part's 48 V ~ 660 V specification. This difference must be evaluated against the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the H12WD4890G-10 and 84138150N are active production components with RoHS compliance and identical moisture sensitivity ratings. The primary distinction is the load voltage operating range. The H12WD4890G-10 supports higher voltage applications up to 660 V, while the 84138150N is rated to 500 V maximum. The Crouzet substitute includes zero-cross detection functionality, which is not specified for the Sensata device. Selection between these parts depends on whether the application load voltage requirement falls within the 24 V ~ 500 V range of the substitute or requires the extended 48 V ~ 660 V capability of the main part.

Frequently Asked Questions (FAQ)

Q: Can the 84138150N replace the H12WD4890G-10 in all applications?

A: The 84138150N is mechanically and electrically compatible for applications where the load voltage does not exceed 500 V. If your application requires load voltages between 500 V and 660 V, the H12WD4890G-10 is the required choice.

Q: What is the significance of the zero-cross feature in the Crouzet part?

A: Zero-cross detection is a feature present in the 84138150N but not specified for the H12WD4890G-10. This feature synchronizes relay switching with the AC voltage waveform zero crossing point, which can reduce electromagnetic interference in certain applications.

Q: Are both parts available in the same package configuration?

A: Yes. Both the H12WD4890G-10 and 84138150N use the hockey puck package form factor with screw terminal connections and are designed for chassis mount installation.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are RoHS compliant and have identical moisture sensitivity levels (MSL 1 - Unlimited). Both are classified under ECCN EAR99 for export control purposes.

Q: What is the minimum load current these relays can handle?

A: Both parts are rated for 90 A load current. The minimum operating current is not specified in the provided parameters.
