HA48110 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The HA48110 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) device in a hockey puck form factor. This component is designed for AC load switching applications with a rated load current of 110 A and operates across a load voltage range of 48 V to 530 V. The device features zero-cross switching capability and screw terminal connections for industrial applications. The HA48110 maintains Active product status and is RoHS3 compliant, making it suitable for current procurement and deployment in new designs.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical parameters including load current capacity, voltage operating ranges, switching characteristics, and physical form factor. The substitute part listed below meets these criteria while offering alternative sourcing options.

Substitute Part Grouping Explanation

The substitute part 84137141N (Crouzet, GN Series) is classified as a functionally equivalent alternative based on the following critical parameters:

Substitution Criteria:

• Circuit configuration: Both devices are SPST-NO (1 Form A) solid state relays
• Output switching type: Both feature AC output with zero-cross switching
• Physical form factor: Both use hockey puck chassis mount packaging with screw terminals
• Load current capacity: The substitute supports 100 A, which is within acceptable range for applications designed for 110 A operation
• Load voltage range: The substitute operates across 48 V to 660 V, which encompasses the HA48110 range of 48 V to 530 V
• Input voltage compatibility: The substitute accepts 20 ~ 265 VAC input, overlapping with the HA48110 range of 90 ~ 280 VAC

The 84137141N provides equivalent functionality for AC load switching applications where the 110 A rating of the HA48110 is not a limiting factor, or where the extended load voltage capability (up to 660 V) offers system design advantages.

Parameter Comparison

Engineering Selection Recommendations

Both the HA48110 and 84137141N are Active product status devices suitable for current procurement. The HA48110 carries RoHS3 compliance and REACH Affected status, while the 84137141N is RoHS compliant with REACH Unaffected status.

Selection between these parts depends on application-specific requirements:

• The HA48110 is the primary choice when the 110 A load current capacity is required or when RoHS3 compliance is mandated by design specifications.
• The 84137141N serves as an alternative when load current requirements do not exceed 100 A and when REACH Unaffected status provides regulatory or supply chain advantages. The extended load voltage range (up to 660 V) may benefit applications requiring higher voltage operation within the 48 V to 530 V window.

Both devices maintain identical circuit configuration, switching characteristics, and physical form factor, ensuring mechanical and electrical compatibility in chassis mount applications with screw terminal connections.

Frequently Asked Questions (FAQ)

Q: Can the 84137141N replace the HA48110 in all applications?

A: The 84137141N is functionally equivalent for applications where the load current does not exceed 100 A. Both devices share identical SPST-NO circuit configuration, AC zero-cross switching output, hockey puck form factor, and screw terminal termination. Applications requiring the full 110 A capacity of the HA48110 must use the original part number.

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

A: The primary differences are load current rating (HA48110: 110 A vs. 84137141N: 100 A), input voltage range (HA48110: 90 ~ 280 VAC vs. 84137141N: 20 ~ 265 VAC), load voltage maximum (HA48110: 530 V vs. 84137141N: 660 V), and regulatory compliance status (HA48110: RoHS3/REACH Affected vs. 84137141N: RoHS/REACH Unaffected).

Q: Are the physical dimensions and mounting identical?

A: Both parts use hockey puck chassis mount packaging with screw terminal connections, ensuring identical mechanical compatibility in applications designed for either device.

Q: Which part should be selected for new designs?

A: The HA48110 is recommended for new designs requiring the 110 A load current capacity or RoHS3 compliance. The 84137141N is suitable when load current requirements are 100 A or less and when REACH Unaffected status is advantageous for supply chain or regulatory purposes.

Q: Do both parts support zero-cross switching?

A: Yes, both the HA48110 and 84137141N feature AC output with zero-cross switching capability, providing identical switching characteristics for AC load control applications.
