Substitute Part Grouping Explanation

Substitute parts for the HA4812-10 are identified based on the following critical parameters that determine functional compatibility:

• Circuit Configuration: SPST-NO (1 Form A) topology
• Output Type: AC output capability
• Input Voltage Range: Compatibility with 90 ~ 280 VAC control signal
• Load Voltage Range: Minimum 48 V operation with upper range capability
• Load Current Rating: Minimum 12 A capacity
• Mounting and Termination: Chassis mount with screw terminal connections
• Package Form Factor: Hockey puck configuration
• Regulatory Compliance: RoHS compliance requirement

The substitute part 84137211N (Crouzet GN series) qualifies as an equivalent based on matching circuit topology, output type, input voltage compatibility, mounting configuration, termination style, and package form factor. Both parts operate within overlapping electrical specifications and share identical mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

Both the HA4812-10 and 84137211N maintain Active product status, indicating ongoing manufacturer support and availability. Both components carry RoHS compliance certification, meeting regulatory requirements for electronic component applications. The 84137211N provides a higher load current rating (25 A versus 12 A), which offers additional capacity margin in applications requiring the HA4812-10. Selection between these parts should be based on specific application load current requirements and load voltage range constraints. The HA4812-10 supports extended load voltage operation up to 530 V, while the 84137211N operates to 280 V maximum load voltage. Applications requiring load voltages exceeding 280 V necessitate the HA4812-10.

Frequently Asked Questions (FAQ)

Q: Can the 84137211N directly replace the HA4812-10 in all applications?

A: Direct replacement is possible when the application load voltage does not exceed 280 V. The HA4812-10 is required for applications with load voltages between 280 V and 530 V. Both parts share identical circuit topology, mounting configuration, and termination style.

Q: What are the key differences between these two SSR relays?

A: The primary differences are load voltage range and load current rating. The HA4812-10 operates to 530 V load voltage with 12 A capacity. The 84137211N operates to 280 V load voltage with 25 A capacity. Input voltage ranges differ slightly (HA4812-10: 90-280 VAC; 84137211N: 90-260 VAC).

Q: Are both parts suitable for chassis mount applications?

A: Yes. Both the HA4812-10 and 84137211N are designed for chassis mount installation with screw terminal connections and hockey puck form factor packaging.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the HA4812-10 and 84137211N carry RoHS compliance certification and are suitable for applications requiring regulatory compliance.

Q: What determines whether a substitute part is acceptable for a specific application?

A: Substitution compatibility is determined by matching circuit topology (SPST-NO), output type (AC), input voltage range compatibility, load voltage range requirements, load current requirements, mounting type, termination style, and package form factor. The substitute part must meet or exceed the electrical specifications of the original component for the intended application.
