Substitute Part Grouping Explanation
Substitute parts for the CLB-153-12C2N-B-A are qualified based on the following criteria:
Mandatory Matching Parameters:
- Breaker Type: Thermal
- Current Rating: 15A
- Voltage Rating - AC: 250V
- Actuator Type: Push to Reset
- Number of Poles: 1
- Mounting Type: Panel Mount
- Illumination: None
Allowable Variation:
- Voltage Rating - DC: The main part specifies 32V DC. Substitute parts in the CBW57 series are rated for 50V DC, which provides enhanced DC voltage capability while maintaining compatibility with the 32V DC requirement.
All substitute parts are manufactured by OptiFuse, belong to the CBW57 series, maintain Active product status, and are ROHS3 compliant. Approval agencies differ between the main part and substitutes but both sets include UL 1077 and UL 1500 certifications.

Engineering Selection Recommendations
All listed substitute parts satisfy the electrical and mechanical requirements of the CLB-153-12C2N-B-A. Selection among the CBW57 series alternatives should be based on the following factors:
Compliance and Certifications: The main part carries CE, cUL, TUV, UL1077, and UL1500 approvals. All substitute parts carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications. Both sets include UL 1077 and UL 1500, which are the primary safety standards for thermal circuit breakers.
Inventory Availability: Substitute parts demonstrate varying inventory levels. CBW57-HB-15A-P offers the highest stock at 8,822 pieces. CBW57-ES-15A provides 3,521 pieces. Other variants range from 936 to 1,862 pieces. The main part CLB-153-12C2N-B-A maintains 899 pieces in stock.
Moisture Sensitivity Level (MSL): Most OptiFuse CBW57 substitutes specify MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.
DC Voltage Enhancement: All substitute parts are rated for 50V DC compared to the main part's 32V DC rating. This provides additional margin for DC applications without compromising AC performance.
Frequently Asked Questions (FAQ)
Q: Can CBW57 series parts directly replace the CLB-153-12C2N-B-A?
A: Yes. All listed CBW57 variants maintain identical electrical specifications for current rating (15A), AC voltage (250V), actuator type (push to reset), pole count (1), and mounting configuration (panel mount). The 50V DC rating of CBW57 parts exceeds the 32V DC requirement of the main part.
Q: What is the significance of the higher DC voltage rating on substitute parts?
A: The CBW57 series is rated for 50V DC while the CLB-153-12C2N-B-A is rated for 32V DC. This means substitute parts can operate safely in applications requiring up to 50V DC, providing additional design margin. Applications limited to 32V DC or lower operate within the substitute part specifications.
Q: Are there differences in approval agencies between the main part and substitutes?
A: Yes. The main part carries CE, cUL, TUV, UL1077, and UL1500 approvals. Substitute parts carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 approvals. Both include UL 1077 and UL 1500, which are the primary thermal circuit breaker safety standards. Applications requiring specific regional certifications should confirm compliance with local requirements.
Q: What do the suffix codes in CBW57 part numbers indicate?
A: The suffix codes (EJ, EL4, ES, GS, HB, HS, PB, PS) represent different connector or terminal configurations within the CBW57 series. All variants maintain identical electrical and thermal characteristics. Selection should be based on the specific connector or terminal type required for the application.
Q: Is there a difference in packaging between the main part and substitutes?
A: The main part CLB-153-12C2N-B-A specifies packaging as "-" (not specified). All OptiFuse CBW57 substitutes are packaged in Bulk. Confirm bulk packaging compatibility with procurement and assembly requirements.
Q: Which substitute part offers the best inventory availability?
A: CBW57-HB-15A-P provides the highest inventory level at 8,822 pieces. For applications requiring immediate availability, this variant offers the shortest lead time among the listed substitutes.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All listed CBW57 variants are ROHS3 compliant, matching the environmental compliance status of the main part CLB-153-12C2N-B-A.
