CMA24110 Equivalent & Substitute Parts

Part Overview

The CMA24110 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 zero-cross switching capability, designed for high-current load switching applications in the 24V to 280V range. The part is currently in active production status with 759 units available in new original inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMA24110 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Must be AC with zero-cross switching to preserve load control characteristics
• Load Voltage Range: Must encompass or match the 24V to 280V specification
• Mounting Type: Must be Chassis Mount to ensure mechanical fit
• Package / Case: Must be Hockey Puck configuration for form factor compatibility
• Termination Style: Must be Screw Terminal for connection compatibility
• RoHS Compliance: Must maintain RoHS Compliant status for regulatory alignment

The CWA24125 qualifies as a manufacturer-recommended substitute because it satisfies all critical substitution criteria while offering increased load current capacity (125A versus 110A) and an expanded input voltage range (90 ~ 280VAC versus 90 ~ 140VAC).

Parameter Comparison

Engineering Selection Recommendations

Both the CMA24110 and CWA24125 maintain active production status and full RoHS compliance, ensuring long-term availability and regulatory conformance. The CWA24125 provides enhanced specifications in two areas: input voltage tolerance extends to 280VAC (compared to 140VAC maximum for the CMA24110), and load current capacity increases to 125A (compared to 110A). These enhancements make the CWA24125 suitable for applications requiring higher input voltage flexibility or increased current handling without compromising any electrical or mechanical compatibility parameters. Selection between these parts should be based on specific application requirements for input voltage range and load current capacity.

Frequently Asked Questions (FAQ)

Q: Can the CWA24125 be used as a direct replacement for the CMA24110?

A: Yes. Both parts share identical circuit configuration (SPST-NO), output type (AC, zero-cross), load voltage range (24V–280V), mounting type (chassis mount), package configuration (hockey puck), and termination style (screw terminal). The CWA24125 is manufacturer-recommended as a substitute.

Q: What are the key differences between these two parts?

A: The CWA24125 offers two enhancements: input voltage range extends from 90–280VAC (versus 90–140VAC), and load current capacity increases from 110A to 125A. All other electrical and mechanical parameters remain equivalent.

Q: Does the increased load current rating of the CWA24125 affect compatibility?

A: No. Higher current capacity does not compromise compatibility. The CWA24125 maintains the same load voltage range, mounting configuration, and termination style as the CMA24110.

Q: Are both parts RoHS compliant?

A: Yes. Both the CMA24110 and CWA24125 are RoHS Compliant and suitable for applications requiring regulatory compliance.

Q: What is the significance of the hockey puck package configuration?

A: The hockey puck package is a standardized form factor for solid-state relays in this current class. Both parts use this configuration, ensuring mechanical interchangeability in chassis-mount applications with screw terminal connections.

Q: Can these parts be used interchangeably in all applications?

A: Interchangeability depends on application-specific requirements. If the application requires input voltage above 140VAC or load current above 110A, the CWA24125 is necessary. For applications within the CMA24110 specifications, either part is suitable.
