Substitute Part Grouping Explanation
Substitute parts for the CMB-153-11CNN-R-A/15 are qualified based on the following critical parameters that must align with the main part:
Mandatory Matching Parameters:
- Current Rating: 15A
- Voltage Rating - AC: 250V
- Breaker Type: Thermal
- Actuator Type: Push to Reset
- Mounting Type: Panel Mount
- Number of Poles: 1
- Illumination: None
Allowable Variation:
- Voltage Rating - DC: The main part specifies 32V DC. Substitute parts rated at 50V DC are acceptable as this represents a higher voltage capability and maintains backward compatibility in applications operating at or below 32V DC.

Engineering Selection Recommendations
All identified substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the original CMB-153-11CNN-R-A/15 component. The OptiFuse CBW57 series substitutes carry approval certifications including cURus, IP 40, SAE J1171, UL 1077, and UL 1500, which provide equivalent or complementary safety and performance validation to the original part's CE, cUL, TUV, UL1077, and UL1500 approvals.
The primary technical distinction between the main part and all substitute options is the DC voltage rating: the CMB-153-11CNN-R-A/15 is rated at 32V DC, while all CBW57 series substitutes are rated at 50V DC. This higher DC rating in substitute parts does not restrict their application in circuits designed for 32V DC operation, as the component maintains full functionality at lower voltage levels.
Component selection should be based on availability, inventory levels, and specific connector or terminal configurations required by the application. All listed substitutes are electrically and mechanically interchangeable for applications requiring a 15A thermal circuit breaker with 250V AC and push-to-reset panel mount functionality.
Frequently Asked Questions (FAQ)
Q: Can CBW57 series parts directly replace the CMB-153-11CNN-R-A/15?
A: Yes. All listed CBW57 series parts from OptiFuse are direct substitutes. They share identical current rating (15A), AC voltage rating (250V), actuator type (push to reset), mounting configuration (panel mount), and pole count (1). The higher DC voltage rating (50V versus 32V) in substitute parts does not prevent replacement in 32V DC applications.
Q: What is the significance of the DC voltage rating difference?
A: The CMB-153-11CNN-R-A/15 is rated for 32V DC maximum, while all CBW57 substitutes are rated for 50V DC maximum. A higher voltage rating indicates the component can safely operate at voltages up to that limit. Substitutes with 50V DC rating are suitable for applications operating at 32V DC or lower.
Q: Are there differences in connector or terminal types among the substitute parts?
A: The provided specifications do not include connector or terminal configuration details. Part number suffixes (such as -5X, -WB, -WX, -P) indicate different connector or terminal variants within the CBW57 series. Selection of the specific substitute part should account for the terminal type required by the application circuit.
Q: Do all substitute parts carry the same regulatory approvals?
A: The CMB-153-11CNN-R-A/15 carries CE, cUL, TUV, UL1077, and UL1500 approvals. All CBW57 substitutes carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 approvals. Both sets of certifications validate safety and performance for thermal circuit breaker applications. The specific approval requirements for your application should be confirmed against your design specifications.
Q: What inventory levels are available for each substitute part?
A: Inventory availability varies by part number. CBW57-HB-15A-P has the highest inventory at 8,822 pieces, while CBW57-PB-15A-WX has the lowest at 936 pieces. Current inventory levels should be confirmed with your component supplier for procurement planning.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed substitute parts are ROHS3 compliant, matching the environmental compliance status of the original CMB-153-11CNN-R-A/15 component.
Q: Can I use these substitutes in both AC and DC applications?
A: Yes. All parts, including the main component and substitutes, are rated for both AC (250V) and DC (32V or 50V) operation. The thermal breaker type provides overcurrent protection in both AC and DC circuits.
