Substitute Part Grouping Explanation
Substitution of the CLB-103-11ANN-B-A is determined by strict equivalence across the following critical parameters:
Mandatory Matching Parameters:
- Current Rating: 10A
- Voltage Rating - AC: 250V
- Mounting Type: Panel Mount
- Breaker Type: Thermal
- Actuator Type: Push to Reset
- Number of Poles: 1
- Illumination: None
Allowable Variation:
- Voltage Rating - DC: The CLB-103-11ANN-B-A operates at 32V DC. All qualified substitute parts from OptiFuse (CBW57 series) operate at 50V DC, which represents a higher DC voltage capability and is functionally compatible for applications requiring 32V DC operation.
All substitute parts listed are manufactured by OptiFuse under the CBW57 series designation. Each substitute maintains identical AC voltage rating (250V), current rating (10A), mounting configuration (panel mount), actuation method (push to reset), and pole count (1). All substitute parts are active products with RoHS3 compliance and REACH unaffected status. Approval agencies for substitute parts include cURus, IP 40, SAE J1171, UL 1077, and UL 1500, providing equivalent or superior certification coverage.

Engineering Selection Recommendations
All listed substitute parts are qualified equivalents for the CLB-103-11ANN-B-A based on matching electrical specifications and mechanical form factor. Selection among the OptiFuse CBW57 series variants should be based on the specific connector or terminal configuration required by the application, as indicated by the suffix designations in each part number.
Compliance Considerations:
The CLB-103-11ANN-B-A carries approvals from CE, cUL, TUV, UL1077, and UL1500. All substitute parts carry approvals from cURus, IP 40, SAE J1171, UL 1077, and UL 1500. Both the primary part and all substitutes maintain RoHS3 compliance and REACH unaffected status. The substitute parts provide equivalent or superior regulatory coverage for industrial and commercial applications.
DC Voltage Rating:
The primary part is rated for 32V DC operation. All substitute parts are rated for 50V DC operation. This higher DC rating in the substitute parts provides additional safety margin and is fully compatible with applications designed for 32V DC operation.
Inventory Availability:
The CLB-103-11ANN-B-A has 763 units in stock. OptiFuse CBW57 series parts range from 701 to 5818 units in stock across the various configurations, providing multiple sourcing options with varying availability levels.
Frequently Asked Questions (FAQ)
Q: Can CBW57 series parts directly replace the CLB-103-11ANN-B-A?
A: Yes. All CBW57 series parts listed are direct functional equivalents. They match the CLB-103-11ANN-B-A across all critical parameters: 10A current rating, 250V AC voltage rating, panel mount configuration, thermal breaker type, push-to-reset actuation, and single-pole design. The higher 50V DC rating in CBW57 parts is compatible with 32V DC applications.
Q: What do the suffix designations in CBW57 part numbers indicate?
A: The suffix designations (such as -EJ, -EL4, -ES, -PB, -PF, -PL, -PS) indicate different connector or terminal configurations. Selection of the appropriate suffix depends on the specific terminal type required by your application circuit board or wiring harness.
Q: Are all substitute parts certified to the same standards?
A: All substitute parts carry UL 1077 and UL 1500 certifications, matching the primary part. Substitute parts additionally carry cURus, IP 40, and SAE J1171 approvals. All parts maintain RoHS3 compliance and REACH unaffected status.
Q: Is the higher DC voltage rating of CBW57 parts a concern?
A: No. The CBW57 series 50V DC rating is a higher capability rating than the CLB-103-11ANN-B-A 32V DC rating. A component rated for higher voltage is suitable for lower voltage applications. This provides additional design margin.
Q: Which CBW57 variant should I select?
A: Selection depends on your specific terminal or connector requirements. CBW57-PS-10A and CBW57-PS-10A-5X variants have the highest inventory availability (4730 and 5818 units respectively). Consult your application's mechanical interface specifications to determine the correct suffix designation.
Q: Can I use these parts interchangeably in existing designs?
A: Interchangeability depends on the mechanical form factor and terminal configuration of your specific application. All listed parts share identical electrical ratings and panel-mount form factor. Verify that the terminal configuration of your selected substitute matches your application's connector or wiring interface.
