HA6025G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The HA6025G is a Solid State Relay (SSR) manufactured by Sensata-Crydom, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a 1 Form A circuit configuration. This hockey puck-style relay is designed for AC load switching applications with a rated load current of 25A across a voltage range of 48V to 660V. The device features zero-cross switching capability and operates with an input voltage range of 90V to 280VAC. Currently in active production status with RoHS compliance and unlimited moisture sensitivity rating (MSL 1), the HA6025G is widely stocked with 926 units available. Equivalent parts are identified to support procurement flexibility, supply chain continuity, and application-specific requirements where direct substitution is electrically and mechanically viable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA6025G is determined by strict alignment of the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) topology must be identical
• Load Current Rating: 25A nominal capacity required
• Load Voltage Range: 48V to 660V operating window must be supported
• Output Switching Type: AC with zero-cross functionality
• Package Form Factor: Hockey puck chassis-mount configuration
• Termination Interface: Screw terminal connection method
• Compliance Status: RoHS compliance and active product status

The substitute part 84137111N (Crouzet, Series GN) meets all substitution criteria. While the input voltage range differs (20V to 265VAC versus 90V to 280VAC), the load-side parameters—which determine switching capability and application compatibility—are fully equivalent. Both parts share identical load current, load voltage range, circuit type, output switching characteristics, package form factor, and termination style.

Parameter Comparison

Engineering Selection Recommendations

Both the HA6025G and 84137111N are active-status products with full RoHS compliance, ensuring regulatory alignment for current and future applications. Selection between these parts should be based on:

HA6025G (Sensata-Crydom): Primary selection when input voltage supply is confirmed within the 90V to 280VAC range. Established supply availability with 926 units in stock.

84137111N (Crouzet): Suitable alternative when input voltage supply operates within the 20V to 265VAC range, particularly for applications requiring lower input voltage thresholds. Available inventory of 1092 units provides supply redundancy.

Both parts are mechanically and electrically interchangeable for load-side applications. Input voltage range differences do not affect load switching performance, as the load-side parameters are identical. Selection should account for control circuit voltage availability and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the 84137111N replace the HA6025G in an existing application?

A: Yes, provided the control circuit input voltage operates within the 20V to 265VAC range. All load-side parameters—current rating, voltage range, switching type, and package form factor—are identical. Physical mounting and terminal connections are compatible.

Q: What is the significance of the different input voltage ranges?

A: The input voltage range specifies the control signal voltage required to activate the relay. The HA6025G requires 90V to 280VAC, while the 84137111N operates from 20V to 265VAC. The overlapping range (90V to 265VAC) permits direct substitution in applications within this window. Applications using input voltages below 90VAC or above 265VAC require the specific part rated for that range.

Q: Are the hockey puck packages physically identical?

A: Yes. Both parts use the hockey puck chassis-mount form factor with screw terminal connections, ensuring mechanical compatibility in existing mounting configurations.

Q: Do both parts support zero-cross switching?

A: Yes. Both the HA6025G and 84137111N feature AC output with zero-cross switching capability, providing identical switching characteristics for AC load applications.

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

A: Both parts are rated for 25A continuous load current across the 48V to 660V load voltage range.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are RoHS compliant with MSL 1 (unlimited moisture sensitivity) ratings and carry identical ECCN (EAR99) and HTSUS (8536.49.0080) classifications.
