HA4875-10 Equivalent & Substitute Parts

Part Overview

The HA4875-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) hockey puck configuration. This component functions as an AC output relay with a load current capacity of 75 A and operates across a load voltage range of 48 V to 530 V. The device is actively produced and RoHS compliant. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, application requirements, or design flexibility within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

The HA4875-10 accepts substitution with the Crouzet 84138153N based on the following allowed electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPST-NO (1 Form A)
• Package type: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Load voltage range overlap: Both support 48 V minimum and extend to 500 V or higher
• Load current capacity: Substitute rated at 90 A exceeds the 75 A requirement
• Input voltage compatibility: Substitute input range (20 ~ 260 VAC/DC) encompasses the primary part input range (90 ~ 280 VAC)
• Output type: Both AC output configurations
• Regulatory compliance: Both RoHS compliant

Parameter Comparison

Engineering Selection Recommendations

Both the HA4875-10 and 84138153N are active production components with RoHS compliance certification. The Crouzet 84138153N provides equivalent functionality within the specified electrical and mechanical parameters. The substitute part offers increased load current capacity (90 A versus 75 A) and includes zero-cross switching capability. Both components maintain identical circuit topology, package configuration, and termination methodology, supporting direct substitution in applications requiring SPST-NO solid state relay functionality in the hockey puck form factor.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138153N directly replace the HA4875-10 in existing designs?

A: Yes. Both components share identical circuit type (SPST-NO), package configuration (hockey puck), mounting type (chassis mount), and termination style (screw terminal). The substitute part meets or exceeds all specified electrical parameters.

Q: What is the load voltage compatibility between these parts?

A: The HA4875-10 operates across 48 V to 530 V. The Crouzet 84138153N operates across 24 V to 500 V. Applications requiring load voltages between 48 V and 500 V are compatible with both components.

Q: How do the input voltage ranges compare?

A: The HA4875-10 accepts 90 ~ 280 VAC input. The Crouzet 84138153N accepts 20 ~ 260 VAC/DC input. The substitute part supports a broader input range, including DC operation, though the primary AC operating range of 90 ~ 260 VAC overlaps with the original specification.

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

A: Zero-cross switching is an additional feature in the Crouzet 84138153N that synchronizes relay switching with AC voltage zero crossings. This feature does not prevent substitution and may provide benefits in noise-sensitive applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the HA4875-10 and 84138153N are RoHS compliant components suitable for applications requiring regulatory compliance.

Q: What is the load current difference between these parts?

A: The HA4875-10 is rated for 75 A load current. The Crouzet 84138153N is rated for 90 A. The substitute part provides 15 A additional capacity, supporting applications at or below the original 75 A specification.
