CLB-103-11ANN-W-F Equivalent & Substitute Parts
Part Overview
The CLB-103-11ANN-W-F is a thermal circuit breaker manufactured by Carling Technologies, designed for panel mount applications. This single-pole device provides overcurrent protection at 10A with dual voltage ratings of 250V AC and 32V DC. The push-to-reset actuator enables manual circuit restoration following a thermal trip event. The component is currently active in production status with full compliance to CE, cUL, TUV, UL1077, and UL1500 standards.
Substitute parts are identified when equivalent electrical and mechanical parameters align with the main component specifications, enabling direct functional replacement in circuit protection applications.

Substitute Part Grouping Explanation
Substitute parts for the CLB-103-11ANN-W-F are qualified based on the following critical parameters:
Electrical Equivalence Requirements:
- Current Rating: 10A (exact match)
- Voltage Rating - AC: 250V (exact match)
- Voltage Rating - DC: 50V minimum (CLB-103-11ANN-W-F rated at 32V DC; all substitutes rated at 50V DC, providing equal or greater capability)
Mechanical & Functional Equivalence Requirements:
- Breaker Type: Thermal (exact match)
- Actuator Type: Push to Reset (exact match)
- Number of Poles: 1 (exact match)
- Mounting Type: Panel Mount (exact match)
Compliance Requirements:
- RoHS3 Compliant (all substitutes meet this requirement)
- Active product status (all substitutes are active)
All OptiFuse CBW57 series variants listed meet these substitution criteria. The DC voltage rating differential (50V vs. 32V) represents an uprated specification that maintains backward compatibility with the original application.

Engineering Selection Recommendations
All listed OptiFuse CBW57 series circuit breakers function as direct electrical and mechanical equivalents to the CLB-103-11ANN-W-F. Selection among substitute options is determined by:
Compliance Alignment: All substitute parts maintain ROHS3 compliance and active product status, matching the regulatory posture of the original component. OptiFuse substitutes carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications, providing equivalent safety and performance validation.
Voltage Rating Consideration: The CBW57 series components are rated at 50V DC, compared to the CLB-103-11ANN-W-F rating of 32V DC. This represents an uprated specification that maintains full backward compatibility with applications designed for the original 32V DC specification.
Inventory Availability: OptiFuse CBW57-PS-10A-5X maintains the highest inventory level at 5,818 pieces, followed by CBW57-PS-10A at 4,730 pieces. These variants provide optimal supply chain continuity for high-volume applications.
Moisture Sensitivity: All OptiFuse substitutes carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.
Frequently Asked Questions (FAQ)
Q: Can OptiFuse CBW57 series parts directly replace the CLB-103-11ANN-W-F in existing applications?
A: Yes. All listed CBW57 variants meet the electrical and mechanical requirements for direct substitution. The 10A current rating, 250V AC voltage rating, push-to-reset actuator, single-pole configuration, and panel mount design are identical across all qualified substitutes.
Q: What is the significance of the 50V DC rating on CBW57 substitutes versus the 32V DC rating on the CLB-103-11ANN-W-F?
A: The CBW57 series carries a higher DC voltage rating of 50V, which exceeds the original 32V DC specification. This uprated specification maintains full compatibility with applications designed for 32V DC operation while providing additional capability margin.
Q: Are there differences in thermal trip characteristics between the CLB-103-11ANN-W-F and CBW57 substitutes?
A: All qualified substitutes share identical breaker type (thermal) and current rating (10A) specifications. Thermal trip characteristics are determined by these parameters and are equivalent across all listed parts.
Q: What certifications apply to the OptiFuse CBW57 substitutes?
A: OptiFuse CBW57 series components carry cURus, IP 40, SAE J1171, UL 1077, and UL 1500 certifications. These certifications align with the safety and performance standards applicable to the original CLB-103-11ANN-W-F component.
Q: Are there packaging or lead configuration differences among the CBW57 variants?
A: All listed CBW57 variants are supplied in bulk packaging. Suffix designations in part numbers (such as -PS, -PF, -PL, -PB, -EJ, -EL4, -ES) indicate internal configuration or terminal variations. These differences do not affect electrical equivalence for the specified 10A, 250V AC, 50V DC thermal circuit breaker function.
Q: Which CBW57 variant should be selected for new designs?
A: Selection among CBW57 variants is based on specific terminal or configuration requirements defined by the suffix designation. For applications requiring the highest inventory availability, CBW57-PS-10A-5X and CBW57-PS-10A are recommended.
Q: Is RoHS3 compliance maintained across all substitute options?
A: Yes. All listed OptiFuse CBW57 variants are ROHS3 compliant, matching the regulatory compliance of the original CLB-103-11ANN-W-F component.
