CMA2425-10 Equivalent & Substitute Parts

Part Overview

The CMA2425-10 is a solid state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (1 Form A) hockey puck configuration. This component functions as an AC output relay with a 25A load capacity and operates across a 24V to 280V load voltage range. The part is currently in active product status with 785 units available in inventory. Substitute parts are identified when electrical specifications, mechanical form factor, and termination methods align with the original component, enabling direct replacement in existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMA2425-10 are identified based on the following critical parameters that must remain consistent:

• Circuit configuration: SPST-NO (1 Form A)
• Output type: AC
• Load current rating: 25 A
• Load voltage range: 24 V ~ 280 V
• Package form factor: Hockey Puck
• Mounting type: Chassis Mount
• Termination style: Screw Terminal

The CWA2425-10 qualifies as a manufacturer-recommended substitute because it maintains all critical electrical specifications and mechanical characteristics. Variations in input voltage range and series designation do not affect substitutability when load-side parameters and physical form factor remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the CMA2425-10 and CWA2425-10 are active products from Sensata-Crydom with confirmed RoHS compliance. The CWA2425-10 provides an extended input voltage range (90 ~ 280VAC versus 90 ~ 140VAC) and includes REACH compliance documentation. Selection between these parts depends on the specific input voltage requirements of the application. When input voltage exceeds 140VAC, the CWA2425-10 is the appropriate selection. For applications operating within the 90 ~ 140VAC range, either part satisfies the electrical requirements.

Frequently Asked Questions (FAQ)

Q: Can the CWA2425-10 replace the CMA2425-10 in all applications?

A: The CWA2425-10 is compatible with applications designed for the CMA2425-10 when the input voltage does not exceed 280VAC. The extended input voltage range of the CWA2425-10 provides broader operational flexibility. Physical form factor, load specifications, and termination methods are identical.

Q: What is the significance of the different series designations (CMA24 versus CW24)?

A: Series designation reflects internal product line organization within Sensata-Crydom. Both series share identical electrical performance and mechanical specifications for the 25A, 24-280V load configuration. Series differences do not affect substitutability.

Q: Are there packaging differences between these parts?

A: The CMA2425-10 is specified with standard packaging, while the CWA2425-10 is supplied in bulk packaging. Both maintain the hockey puck form factor and screw terminal configuration. Packaging differences do not affect electrical or mechanical compatibility.

Q: What compliance certifications apply to each part?

A: The CMA2425-10 carries RoHS Compliant certification. The CWA2425-10 carries ROHS3 Compliant certification and is REACH Affected. Both parts comply with applicable environmental regulations for their respective designations.

Q: How do I determine which substitute part is appropriate for my application?

A: Verify that your application's input voltage requirement falls within the specified range of the candidate part. Confirm that load voltage (24 ~ 280V) and load current (25A) requirements match. Verify that the chassis mount configuration and screw terminal termination are compatible with your installation. Both parts satisfy these criteria; selection depends on input voltage specifications.
