Sensata-Crydom A2450-10 Equivalent & Substitute Parts

Part Overview

The Sensata-Crydom A2450-10 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 50A load current and 24-280V operation. This active product is designed for chassis mount applications with screw terminal connections in a hockey puck package. Equivalent and substitute parts may be required due to inventory availability, regional sourcing constraints, or specific application voltage requirements that fall within acceptable operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A)
• Output Type: Must be AC
• Load Current Rating: Must be 50 A
• Package Type: Must be Hockey Puck
• Mounting Type: Must be Chassis Mount
• Termination Style: Must be Screw Terminal

Substitute parts are grouped into two categories based on voltage operating ranges:

Category 1 - Direct Voltage Range Match (24-280V Load): Parts with identical load voltage specifications to the main part.

Category 2 - Extended Voltage Range (48-660V Load): Parts with expanded load voltage capability that encompasses the main part's operating range, suitable for applications requiring higher voltage tolerance.

Parameter Comparison

Engineering Selection Recommendations

Sensata-Crydom 84134221: This substitute maintains identical electrical specifications to the A2450-10, including input voltage range (90-280VAC) and load voltage range (24-280V). Both parts are manufactured by Sensata-Crydom and carry active product status with RoHS compliance. This part is suitable for direct replacement in applications with the specified voltage parameters.

Crouzet 84137321N: This substitute provides expanded load voltage capability (48-660V), which encompasses the A2450-10 operating range. The input voltage range is slightly reduced (90-260VAC versus 90-280VAC). This part is manufactured by Crouzet and carries active product status with RoHS compliance. Selection of this part is appropriate for applications requiring higher load voltage tolerance, provided the input voltage requirement does not exceed 260VAC.

Both substitute parts maintain the same circuit configuration, current rating, package type, and termination style as the main part, ensuring mechanical and electrical compatibility within their respective voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84137321N be used in place of the A2450-10 in all applications?

A: The Crouzet 84137321N is compatible with applications operating within its specified input voltage range (90-260VAC) and load voltage range (48-660V). Applications requiring input voltages above 260VAC must use the A2450-10 or the Sensata-Crydom 84134221.

Q: What is the primary difference between the Sensata-Crydom 84134221 and the A2450-10?

A: Both parts are manufactured by Sensata-Crydom with identical electrical specifications. The 84134221 is designated as Series GN, while the A2450-10 is Series 1. Both maintain the same voltage ratings, current capacity, and package configuration.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts share the same package type (Hockey Puck), mounting type (Chassis Mount), and termination style (Screw Terminal), ensuring mechanical compatibility in chassis mount applications.

Q: Which substitute part should be selected for maximum voltage flexibility?

A: The Crouzet 84137321N provides the widest load voltage range (48-660V), making it suitable for applications requiring operation across a broader voltage spectrum. However, the input voltage maximum is limited to 260VAC.

Q: Are there any compliance differences between the substitute parts?

A: All three parts carry RoHS compliance. The A2450-10 is ROHS3 Compliant and REACH Affected. The Sensata-Crydom 84134221 and Crouzet 84137321N are RoHS Compliant, with the Crouzet part listed as REACH Unaffected.
