CMA6050-10 Equivalent & Substitute Parts

Part Overview

The CMA6050-10 is a solid-state relay (SSR) with SPST-NO (1 Form A) configuration, rated for 50A load current and 48V to 660V output voltage range. This chassis-mount hockey puck package device is designed for AC output switching applications with 90-140VAC input control voltage. The product is currently active and RoHS compliant, with 850 units available in inventory. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate different input voltage specifications or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

The CMA6050-10 can be substituted with the CWA4850-10 based on the following matching electrical and mechanical parameters:

• Circuit configuration: Both are SPST-NO (1 Form A)
• Output type: Both provide AC output
• Load voltage range: Both support 48 V ~ 660 V
• Load current rating: Both rated at 50 A
• Mounting type: Both are chassis mount
• Termination style: Both use screw terminals
• Package type: Both use hockey puck form factor

The primary difference between these parts is the input voltage specification. The CMA6050-10 accepts 90-140VAC input, while the CWA4850-10 accepts a wider range of 90-280VAC input. The CWA4850-10 also carries ROHS3 compliance and REACH affected status, compared to the CMA6050-10's RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

Both the CMA6050-10 and CWA4850-10 are active products from Sensata-Crydom with equivalent electrical and mechanical specifications for 50A AC output switching applications. Selection between these parts should be based on input voltage requirements:

• Use CMA6050-10 when the control circuit operates within the 90-140VAC range and RoHS compliance is the primary regulatory requirement.
• Use CWA4850-10 when the control circuit requires operation across the extended 90-280VAC input range, or when ROHS3 compliance and REACH compliance status are required.

Both parts are suitable for direct substitution in applications where the input voltage specification of the selected part matches the system design requirements.

Frequently Asked Questions (FAQ)

Q: Can the CWA4850-10 be used as a direct replacement for the CMA6050-10?

A: Yes, the CWA4850-10 can replace the CMA6050-10 in applications where the control input voltage does not exceed 280VAC. Both parts share identical load current, voltage, circuit configuration, and mechanical specifications. Verify that your control circuit voltage falls within the CWA4850-10's 90-280VAC input range.

Q: What is the key difference between these two SSR models?

A: The primary difference is the input voltage specification. The CMA6050-10 is rated for 90-140VAC input, while the CWA4850-10 accepts 90-280VAC input. The CWA4850-10 also carries ROHS3 and REACH compliance certifications.

Q: Are both parts available in the same package type?

A: Yes, both the CMA6050-10 and CWA4850-10 use the hockey puck chassis-mount package with screw terminal connections, ensuring mechanical and electrical compatibility in the same mounting footprint.

Q: Which part should I select for a new design?

A: For new designs, consider the CWA4850-10 if your application may encounter input voltages up to 280VAC, as it provides greater operational flexibility. If your control circuit is limited to 90-140VAC, either part is suitable based on compliance and inventory availability requirements.

Q: Are there any compliance differences between these parts?

A: The CMA6050-10 is RoHS compliant. The CWA4850-10 is ROHS3 compliant and REACH affected. Select based on your regulatory and supply chain requirements.
