HD60125G Solid State Relay - Equivalent & Substitute Parts

Part Overview

The HD60125G is an active Sensata-Crydom solid state relay (SSR) designed for industrial switching applications. This SPST-NO (1 Form A) relay operates with AC output and zero-cross switching capability, rated for 125A load current across 48V to 660V AC supply ranges. The device features a hockey puck form factor with screw terminal connections, suitable for chassis mount installations. As an active product with RoHS compliance and unlimited moisture sensitivity rating, the HD60125G remains in production. Equivalent substitute parts may be required due to supply chain availability, regional sourcing preferences, or specific packaging requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HD60125G is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching topology
• Output Type: Must be AC with zero-cross switching to ensure compatible control behavior
• Input Voltage Range: Must support 4 ~ 32VDC control signal specification
• Load Voltage Range: Must cover 48 V ~ 660 V AC operation
• Load Current Rating: Must be rated for 125 A continuous operation
• Package Form Factor: Must be hockey puck configuration for mechanical compatibility
• Termination: Must use screw terminal connections
• Mounting: Must support chassis mount installation

The substitute part 84137180N (Crouzet GN series) meets all these criteria, providing functional and mechanical equivalence despite different manufacturer origin and packaging format (Box vs. Bulk).

Frequently Asked Questions (FAQ)

Q: Can the 84137180N replace the HD60125G in existing designs? A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: identical circuit configuration, voltage ratings, current capacity, input/output characteristics, and physical form factor.

Q: Are there differences in control signal requirements? A: No. Both parts accept 4 ~ 32VDC input voltage, ensuring compatible control circuit integration.

Q: Does the hockey puck package differ between manufacturers? A: The package designation is identical for both parts. Mechanical compatibility is maintained for chassis mount applications with screw terminal connections.

Q: What is the significance of zero-cross switching in these relays? A: Zero-cross switching ensures the relay transitions at AC voltage zero-crossing points, reducing electromagnetic interference and switching stress on connected loads.

Q: Are there compliance differences between the two parts? A: Both parts are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity). The 84137180N additionally carries REACH Unaffected certification.

Q: Does packaging format affect electrical performance? A: No. Bulk and box packaging formats do not affect component performance. Selection should be based on inventory management and supply chain requirements.
