HA4825-10 Equivalent & Substitute Parts

Part Overview

The HA4825-10 is a solid-state relay (SSR) manufactured by Sensata Technologies, configured as a single-pole single-throw normally open (SPST-NO) device. This component is designed for AC load switching applications with a rated load current of 25 A and operates across a load voltage range of 48 V to 530 V. The unit features a hockey puck form factor with screw terminal connections and is mounted as a chassis component. The product maintains active status and is RoHS compliant. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA4825-10 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching functionality
• Output Type: Must be AC to ensure compatibility with the load circuit
• Load Current Rating: Must be rated for 25 A minimum
• Package Type: Must be hockey puck form factor to ensure mechanical fit in chassis mount applications
• Termination Style: Must use screw terminal connections for direct connection compatibility
• Mounting Type: Must support chassis mount installation

The substitute part 84137211N (Crouzet, Series GN) meets these core substitution criteria. However, the load voltage range differs: the substitute operates at 24 V – 280 V compared to the main part's 48 V – 530 V range. This difference must be evaluated against the specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the HA4825-10 and 84137211N are active products with RoHS compliance and identical circuit configurations, current ratings, and mechanical form factors. Selection between these parts depends on load voltage requirements:

• HA4825-10: Select when load voltage exceeds 280 V or falls below 24 V, or when the full 48 V – 530 V range is required
• 84137211N: Select when load voltage operates within the 24 V – 280 V range and supply chain or cost considerations favor the Crouzet alternative

Both parts are classified under HTSUS code 8536.49.0080 and carry ECCN designation EAR99. The Crouzet part carries REACH Unaffected status and MSL rating of 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the 84137211N substitute for the HA4825-10 in all applications?

A: No. The 84137211N has a maximum load voltage rating of 280 V, while the HA4825-10 operates up to 530 V. Substitution is valid only when the application load voltage does not exceed 280 V and is not below 24 V.

Q: Are the physical dimensions and mounting interfaces identical?

A: Both parts use the hockey puck package type with screw terminal connections and chassis mount configuration. Physical compatibility is maintained for direct replacement within the specified voltage operating range.

Q: What is the difference in input voltage specifications?

A: The HA4825-10 accepts input voltage from 90 – 280 VAC, while the 84137211N accepts 90 – 260 VAC. Both ranges overlap substantially; however, the HA4825-10 provides a 20 VAC margin at the upper limit.

Q: Are both parts RoHS compliant?

A: Yes. Both the HA4825-10 and 84137211N are RoHS compliant and suitable for applications requiring environmental compliance.

Q: What packaging options are available?

A: The HA4825-10 is supplied in bulk packaging, while the 84137211N is supplied in box packaging. Packaging format does not affect electrical or mechanical compatibility.
