Key Parameters

Substitute Part Grouping Explanation

The CWA4850-10 qualifies as a direct substitute based on the following alignment of critical parameters:

• Circuit Configuration: Both parts maintain SPST-NO (1 Form A) topology
• Output Type: Both deliver AC output
• Load Current Rating: Both rated at 50 A
• Mounting Type: Both are chassis-mount configurations
• Package Type: Both use Hockey Puck form factor
• Termination Style: Both employ screw terminal connections

The CWA4850-10 extends the input voltage range to 90 ~ 280 VAC and increases the maximum load voltage to 48 V ~ 660 V, making it suitable for applications requiring broader operational envelope while maintaining the same current-handling capacity and physical interface.

Parameter Comparison

Engineering Selection Recommendations

CMA4850-10 is the primary selection for applications with input voltage limited to 90 ~ 140 VAC and load voltage requirements up to 530 V. This part maintains RoHS compliance and is actively manufactured.

CWA4850-10 is the appropriate substitute when:

• Input voltage supply extends to 280 VAC
• Load voltage requirements exceed 530 V up to 660 V
• ROHS3 compliance is required
• Extended operational envelope is necessary while maintaining 50 A current capacity

Both parts are active products from the same manufacturer with identical circuit topology, current rating, and physical form factor. Selection between them depends solely on the voltage requirements of the specific application.

Frequently Asked Questions (FAQ)

Q: Can CWA4850-10 replace CMA4850-10 in all applications?

A: CWA4850-10 can replace CMA4850-10 when the application input voltage does not exceed 280 VAC and load voltage does not exceed 660 V. The extended voltage ranges of CWA4850-10 make it compatible with CMA4850-10 applications. However, verify that your specific application voltage requirements fall within both parts' operating ranges.

Q: What is the primary difference between these two parts?

A: The primary differences are input voltage range (CMA4850-10: 90 ~ 140 VAC; CWA4850-10: 90 ~ 280 VAC) and maximum load voltage (CMA4850-10: 530 V; CWA4850-10: 660 V). Both maintain identical 50 A current rating, SPST-NO configuration, and Hockey Puck package.

Q: Are the physical dimensions and mounting interfaces identical?

A: Yes. Both parts use chassis-mount configuration with Hockey Puck form factor and screw terminal connections, ensuring mechanical and electrical interface compatibility.

Q: What compliance certifications apply to each part?

A: CMA4850-10 is RoHS Compliant. CWA4850-10 is ROHS3 Compliant and REACH Affected. Both are classified under ECCN EAR99 and HTSUS 8536.49.0080.

Q: Can I use CMA4850-10 as a substitute for CWA4850-10?

A: CMA4850-10 cannot substitute for CWA4850-10 in applications requiring input voltage above 140 VAC or load voltage above 530 V. Substitution is directional based on voltage envelope requirements.
