HA4890G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The HA4890G is an active Sensata-Crydom solid state relay (SSR) featuring SPST-NO (1 Form A) switching configuration in a hockey puck package. This component is designed for AC load switching applications with input voltage range of 90–280VAC and output voltage capability from 48V to 530V at 90A load current. The part is RoHS compliant and carries MSL rating of 1 (Unlimited). Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific performance needs while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA4890G is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must be AC with zero-cross capability for synchronized switching performance
• Package / Case: Must be hockey puck form factor for mechanical compatibility with existing mounting infrastructure
• Termination Style: Must be screw terminal for direct connection compatibility
• Mounting Type: Must be chassis mount for installation consistency
• Voltage Ratings: Load voltage range must encompass or exceed 48V–530V; input voltage must support the application's control signal range
• Load Current: Must be rated for minimum 90A continuous operation
• Compliance: RoHS compliance and MSL rating of 1 are required for regulatory and environmental compatibility

The Crouzet 84137141N meets these substitution criteria with enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the HA4890G and 84137141N are active products with full RoHS compliance and MSL rating of 1, ensuring regulatory alignment and environmental stability. The 84137141N provides enhanced electrical performance with 100A load current capacity (versus 90A) and extended output voltage range to 660V (versus 530V), offering additional design margin for applications requiring higher current handling or elevated voltage switching. The input voltage range of the 84137141N (20–265VAC) covers the HA4890G operating window, ensuring control signal compatibility. Both components maintain identical mechanical form factor, termination methodology, and circuit topology, enabling direct functional substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 84137141N directly replace the HA4890G in an existing application?

A: Yes. Both relays share identical circuit configuration (SPST-NO), output type (AC, zero-cross), package form factor (hockey puck), termination style (screw terminal), and mounting type (chassis mount). The 84137141N's enhanced current rating (100A vs. 90A) and extended voltage range (48–660V vs. 48–530V) provide functional compatibility with additional performance margin.

Q: What are the key differences between these two parts?

A: The primary differences are load current capacity (84137141N rated 100A vs. HA4890G rated 90A), maximum output voltage (84137141N 660V vs. HA4890G 530V), and input voltage range (84137141N 20–265VAC vs. HA4890G 90–280VAC). Both maintain identical switching topology and mechanical compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the HA4890G and 84137141N are RoHS compliant with MSL rating of 1 (Unlimited), meeting regulatory requirements for environmental and hazardous substance restrictions.

Q: Does the hockey puck package ensure mechanical interchangeability?

A: Yes. Both components use the hockey puck package form factor with chassis mount configuration and screw terminal termination, ensuring direct mechanical compatibility in existing mounting infrastructure.

Q: What determines whether a substitute part is acceptable for this application?

A: Substitution eligibility is determined by matching circuit configuration (SPST-NO), output type (AC, zero-cross), package form factor (hockey puck), termination style (screw terminal), and ensuring the substitute's voltage and current ratings meet or exceed the application requirements. Compliance certifications (RoHS, MSL) must also align.
