Substitute Part Grouping Explanation

Substitution of circuit breaker 991150 is based on strict equivalence of electrical and mechanical parameters. The substitute part 7940102471 qualifies as a parametric equivalent because it maintains identical specifications across all critical selection criteria:

• Current rating: 5A (identical)
• AC voltage rating: 480V (identical)
• DC voltage rating: 65V (identical)
• Breaker type: Thermal Magnetic (identical)
• Mounting configuration: DIN Rail (identical)
• Pole count: 1 (identical)
• Actuator mechanism: Lever (identical)
• Regulatory approvals: CSA C22.2 No 235, UL1077, VDE (identical)
• RoHS compliance: Compliant (identical)

Both parts belong to the Weidmüller CB2200 series and share identical mechanical and electrical interfaces, enabling direct substitution in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

Part 7940102471 is the appropriate selection for applications currently using 991150. The substitute maintains full electrical and mechanical compatibility while offering the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts carry identical regulatory certifications (CSA C22.2 No 235, UL1077, VDE) and RoHS compliance, supporting use in regulated industrial environments. The transition from obsolete to active product status does not introduce compatibility concerns, as all functional parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can 7940102471 directly replace 991150 in existing installations? A: Yes. Both parts are identical in current rating (5A), voltage ratings (480V AC / 65V DC), breaker type (thermal magnetic), mounting method (DIN rail), pole configuration (1-pole), and actuator type (lever). No circuit modifications are required.

Q: What is the primary reason for substitution? A: Part 991150 is classified as obsolete. Part 7940102471 is the active equivalent from the same manufacturer and series, providing continued component availability.

Q: Are regulatory approvals maintained with the substitute? A: Yes. Both parts carry identical approvals: CSA C22.2 No 235, UL1077, and VDE certification. RoHS compliance is maintained.

Q: Does packaging differ between the two parts? A: Packaging specifications differ (991150 listed as "-"; 7940102471 listed as "Bulk"), but this does not affect functional compatibility or installation.

Q: Are there any electrical performance differences? A: No. Both parts are specified identically for current rating, voltage rating (AC and DC), and breaker type. Thermal magnetic response characteristics are equivalent.
