HA48110-10 Solid State Relay - Equivalent & Substitute Parts

Part Overview

The HA48110-10 is an active Sensata-Crydom solid state relay (SSR) featuring SPST-NO (1 Form A) switching configuration in a hockey puck package. This chassis-mount component is designed for AC load switching applications with input voltage range of 90–280VAC and output voltage capability from 48V to 530V at 110A load current. The part is RoHS compliant and classified under ECCN EAR99 with HTSUS code 8536.49.0080. Equivalent substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate alternative suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA48110-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain functional equivalence
• Package Type: Must be Hockey Puck chassis-mount to ensure mechanical compatibility
• Termination Style: Must be Screw Terminal for direct connection compatibility
• Load Current Rating: Substitute must meet or exceed 110A minimum
• Load Voltage Range: Substitute must support the full 48V–530V operating window
• Input Voltage Compatibility: Substitute input voltage range must accommodate the control circuit requirements
• Output Type: AC output capability is required; zero-cross switching is an acceptable enhancement
• Compliance: RoHS compliance and ECCN EAR99 classification are mandatory for equivalent substitution

The identified substitute part 84138183N (Crouzet GN+ series) meets these criteria with enhanced specifications in load current (125A) and input voltage flexibility (20–260VAC/DC), while maintaining full mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the HA48110-10 and 84138183N are active products with RoHS compliance and EAR99 classification, qualifying them for equivalent substitution in applications requiring SPST-NO solid state relay functionality. The Crouzet 84138183N provides enhanced load current capacity (125A versus 110A) and extended input voltage range flexibility (20–260VAC/DC versus 90–280VAC), making it suitable for applications with variable control voltage sources. The zero-cross switching feature in the Crouzet part reduces EMI and is compatible with AC load applications. Both parts maintain identical mechanical form factor (hockey puck chassis mount with screw terminals) and load voltage operating range compatibility (48V–530V for HA48110-10; 24V–500V for 84138183N). Selection between these parts should be based on specific application input voltage requirements and load current demands within the stated ranges.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138183N directly replace the HA48110-10 in existing applications?

A: Yes, provided the application input voltage falls within the 20–260VAC/DC range and the load current requirement does not exceed 125A. Both parts share identical SPST-NO circuit configuration, hockey puck package geometry, screw terminal termination, and chassis-mount design. Verify that the load voltage requirement (24V–500V for Crouzet) aligns with your application specifications.

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

A: Zero-cross switching synchronizes relay activation with the AC voltage zero-crossing point, reducing electromagnetic interference (EMI) and switching transients. This feature is compatible with standard AC load applications and does not prevent substitution.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant, classified as EAR99, and carry HTSUS code 8536.49.0080. Both are active products with equivalent regulatory standing for industrial applications.

Q: What is the load voltage operating window difference?

A: The HA48110-10 operates from 48V to 530V, while the Crouzet 84138183N operates from 24V to 500V. The Crouzet part supports lower minimum voltage (24V versus 48V) but has a slightly lower maximum voltage ceiling (500V versus 530V). Confirm your application load voltage requirement falls within both ranges before substitution.

Q: Does the higher current rating of the Crouzet part (125A) affect compatibility?

A: No. A higher current rating indicates greater capacity and does not compromise compatibility. The Crouzet part can safely handle applications requiring up to 110A, matching the original part's specification, with additional headroom for higher-current applications.
