HA60125-10 Solid State Relay SPST-NO 125A Equivalent & Substitute Parts

Part Overview

The HA60125-10 is a solid state relay (SSR) manufactured by Sensata Technologies, configured as a single-pole single-throw normally open (SPST-NO) device rated for 125A load current. This chassis-mounted hockey puck relay operates with AC output and accepts input voltage from 90 to 280VAC, with load voltage capability spanning 48V to 660V. The component is RoHS compliant and currently in active production status with 981 units available in inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA60125-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Load Current Rating: Must be rated for 125A minimum to handle specified load requirements
• Package Type: Must be Hockey Puck form factor to ensure mechanical compatibility with chassis mounting
• Termination Style: Must use Screw Terminal for direct connection compatibility
• Output Type: Must support AC output operation
• Compliance: Must maintain RoHS compliance status for regulatory alignment

The substitute part 84138183N (Crouzet GN+ series) meets these core substitution criteria. While the Crouzet device operates with a narrower load voltage range (24V to 500V versus 48V to 660V) and includes zero-cross switching capability, it maintains functional equivalence for applications within its specified voltage envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the HA60125-10 and 84138183N are active production components with RoHS compliance certification, qualifying them for use in regulated applications. Selection between these parts depends on application voltage requirements:

• HA60125-10 is suitable for applications requiring load voltages up to 660V
• 84138183N is suitable for applications with load voltages up to 500V

The Crouzet 84138183N includes zero-cross switching functionality, which reduces electromagnetic interference in AC switching applications but does not affect substitution eligibility for standard AC relay applications.

Both components maintain identical 125A load current capacity, SPST-NO circuit configuration, hockey puck package form factor, and screw terminal termination, ensuring mechanical and electrical interchangeability within their respective voltage operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84138183N replace the Sensata HA60125-10 in all applications?

A: The Crouzet part is functionally equivalent for applications where the load voltage does not exceed 500V. Applications requiring load voltages between 500V and 660V must use the HA60125-10.

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

A: Zero-cross switching synchronizes relay activation with the AC voltage zero-crossing point, reducing inrush current and electromagnetic noise. This feature does not affect substitution compatibility for standard AC relay applications.

Q: Are both parts mechanically compatible with the same mounting hardware?

A: Yes. Both components use identical hockey puck package form factor and chassis mount configuration, permitting direct mechanical substitution without hardware modification.

Q: Do both parts accept the same input voltage range?

A: The input voltage ranges differ slightly. The HA60125-10 accepts 90–280VAC, while the 84138183N accepts 20–260VAC/DC. The Crouzet part supports DC input, which the Sensata part does not.

Q: Are both parts suitable for RoHS-regulated applications?

A: Yes. Both the HA60125-10 and 84138183N carry RoHS compliance certification and are suitable for applications subject to RoHS requirements.
