CLB-153-12CNN-W-A Equivalent & Substitute Parts
Part Overview
The CLB-153-12CNN-W-A is a thermal circuit breaker manufactured by Carling Technologies, rated for 15A at 250V AC and 32V DC with push-to-reset panel mount actuation. This single-pole device is classified as Active product status and holds multiple regulatory approvals including CE, cUL, TUV, UL1077, and UL1500 certifications. The component is ROHS3 compliant and REACH unaffected.
Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design flexibility permits selection from alternative manufacturers meeting identical electrical and mechanical specifications. The CLB-153-12CNN-W-A has documented substitute options within the OptiFuse CBW57 series that maintain functional equivalence across critical parameters.

Substitute Part Grouping Explanation
Substitution eligibility for the CLB-153-12CNN-W-A is determined by strict equivalence across the following parameters:
Mandatory Matching Parameters:
- Current Rating: 15A
- Voltage Rating - AC: 250V
- Mounting Type: Panel Mount
- Breaker Type: Thermal
- Actuator Type: Push to Reset
- Number of Poles: 1
- Illumination: None
- RoHS Status: ROHS3 Compliant
Allowable Variance:
- Voltage Rating - DC: The main part specifies 32V DC. Substitute parts rated at 50V DC are functionally equivalent, as higher DC voltage ratings provide equal or greater capability within the same electrical class.
All substitute parts listed are manufactured by OptiFuse under the CBW57 series designation and maintain Active product status. Each substitute meets the electrical and mechanical requirements for direct functional replacement in applications designed for the CLB-153-12CNN-W-A.

Engineering Selection Recommendations
All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with the original CLB-153-12CNN-W-A specification. The OptiFuse CBW57 series alternatives carry regulatory approvals including cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications, which overlap substantially with the original part's approval agencies.
The primary electrical distinction between the main part and substitutes is the DC voltage rating: the CLB-153-12CNN-W-A is rated at 32V DC, while all CBW57 series alternatives are rated at 50V DC. This represents an upward specification variance that does not restrict substitution in applications operating at or below 32V DC. The higher DC rating of substitute parts provides equivalent or superior performance in the electrical operating envelope of the original component.
Selection among the CBW57 substitute options should be based on inventory availability and packaging requirements, as all variants meet the core electrical and mechanical parameters. Inventory levels range from 827 to 8822 pieces across the substitute options, with CBW57-HB-15A-P offering the highest stock position at 8822 units.
Frequently Asked Questions (FAQ)
Q: Can CBW57 series parts directly replace the CLB-153-12CNN-W-A in existing designs?
A: Yes. All listed CBW57 variants are functionally equivalent across the critical parameters of current rating (15A), AC voltage (250V), mounting type (panel mount), breaker type (thermal), actuator type (push to reset), and pole configuration (single pole). The higher DC voltage rating (50V versus 32V) of the CBW57 parts does not restrict their use in applications designed for 32V DC operation.
Q: What is the significance of the different part number suffixes in the CBW57 series?
A: The suffixes (such as -EJ, -EL4, -ES, -GS, -HB, -HS, -PB) denote internal design variations or packaging configurations within the CBW57 series. All variants listed maintain identical electrical specifications and are interchangeable from a functional standpoint.
Q: Are there any compliance or certification differences between the main part and substitutes?
A: Both the CLB-153-12CNN-W-A and all CBW57 substitutes are ROHS3 compliant and REACH unaffected. The original part carries CE, cUL, TUV, UL1077, and UL1500 approvals. The CBW57 substitutes carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 approvals. The overlap in UL 1077 and UL 1500 certifications confirms functional equivalence for standard circuit protection applications.
Q: Which substitute part should be selected if inventory is the primary consideration?
A: CBW57-HB-15A-P offers the highest inventory position with 8822 pieces in stock, followed by CBW57-ES-15A with 3521 pieces. Both maintain identical electrical and mechanical specifications to the original part.
Q: Do the CBW57 substitutes require any design modifications for panel mount installation?
A: No. All substitute parts are specified as panel mount devices with identical mounting type to the CLB-153-12CNN-W-A. No mechanical modifications are required for installation.
Q: What is the Moisture Sensitivity Level (MSL) of the substitute parts?
A: Most CBW57 variants specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This classification applies to CBW57-EJ-15A, CBW57-EL4-15A, CBW57-ES-15A, CBW57-HB-15A-P, CBW57-HS-15A-5X, CBW57-PB-15A, and CBW57-PB-15A-WX. CBW57-ES-15A-5X and CBW57-PB-15A-5X do not specify MSL in the provided data.
