Key Parameters

Substitute Part Grouping Explanation

Substitution of the APL1-1-62-102 is determined by strict equivalence across the following parameters:

• Breaker Type: Magnetic (Hydraulic Delay) protection mechanism
• Current Rating: 1A nominal trip current
• Voltage Rating - AC: 277V minimum
• Actuator Type: Lever manual actuation
• Mounting Configuration: Panel mount form factor
• Number of Poles: Single-pole switching

The W91-X112-1 satisfies all substitution criteria. This part maintains identical functional specifications for current rating, AC voltage rating, actuator type, mounting type, and pole configuration. The substitute part is manufactured by TE Connectivity Potter & Brumfield Relays and carries active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The W91-X112-1 is the designated manufacturer-recommended substitute for the APL1-1-62-102. Selection of this alternative is supported by:

• Product Status Alignment: The substitute maintains active product status, ensuring continued availability and manufacturing support.
• Regulatory Compliance: The W91-X112-1 is RoHS compliant, meeting current environmental and material restriction requirements.
• Functional Equivalence: All critical electrical and mechanical parameters match the original specification, including current rating, AC voltage rating, actuator type, and mounting configuration.
• Standardized Classification: Both parts share identical HTSUS and ECCN classifications, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the W91-X112-1 directly replace the APL1-1-62-102 in existing installations?

A: Yes. The W91-X112-1 matches all critical substitution parameters: 1A current rating, 277V AC voltage rating, lever actuation, panel mount configuration, and single-pole switching. Physical form factor and electrical performance are equivalent.

Q: What is the significance of the DC voltage rating difference?

A: The APL1-1-62-102 specifies 65V DC rating, while the W91-X112-1 does not provide a DC voltage specification in available documentation. For applications requiring DC operation, the original part specification should be consulted to confirm DC voltage requirements against the substitute part's actual DC rating capability.

Q: Why is the original part classified as obsolete?

A: Obsolete status indicates the APL1-1-62-102 is no longer manufactured by Sensata-Airpax. The W91-X112-1 provides functional continuity for systems requiring replacement components.

Q: Does packaging affect substitution compatibility?

A: Packaging (tray for W91-X112-1 versus unspecified for APL1-1-62-102) does not affect electrical or mechanical compatibility. Packaging selection is determined by procurement and inventory requirements.

Q: Are there compliance differences between the two parts?

A: The W91-X112-1 carries RoHS compliance certification. The original part's RoHS status is not specified. Both parts share identical ECCN (EAR99) and HTSUS (8536.20.0020) classifications.
