APL1-1-60-203 Equivalent & Substitute Parts

Part Overview

The APL1-1-60-203 is a single-pole circuit breaker with magnetic-hydraulic delay protection, rated for 20A at 277V AC and 65V DC. Manufactured by Sensata-Airpax, this lever-actuated panel mount breaker is classified as obsolete. Due to its discontinued status, identifying functionally equivalent active alternatives is essential for system maintenance, repair, and new installations where this specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APL1-1-60-203 is determined by strict equivalence across the following critical parameters:

• Breaker Type: Magnetic (Hydraulic Delay) protection mechanism
• Current Rating: 20A
• Voltage Rating - AC: 277V minimum
• Mounting Type: Panel Mount configuration
• Actuator Type: Lever operation
• Number of Poles: Single-pole (1P)

The W91-X1110-20 manufactured by TE Connectivity Potter & Brumfield Relays satisfies all these requirements. This part maintains functional and mechanical compatibility with the original specification while offering active product status and current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The W91-X1110-20 is the qualified substitute for the APL1-1-60-203 based on the following engineering criteria:

Functional Equivalence: Both parts share identical breaker type, current rating, AC voltage rating, mounting configuration, actuator mechanism, and pole count. These parameters define the electrical and mechanical interface requirements for panel-mounted single-pole 20A protection circuits.

Product Status: The W91-X1110-20 maintains active manufacturing status with current inventory availability (861 pcs), ensuring long-term supply chain reliability and technical support access. The APL1-1-60-203 is obsolete with no future production.

Compliance: The W91-X1110-20 is RoHS Compliant and carries EAR99 classification, matching the regulatory framework of the original part. Both parts share identical HTSUS coding (8536.20.0020), confirming tariff classification alignment.

Packaging: The W91-X1110-20 is supplied in bulk packaging, suitable for direct integration into panel assemblies and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the W91-X1110-20 directly replace the APL1-1-60-203 in existing installations?

A: Yes. Both parts are single-pole, 20A, 277V AC lever-actuated panel mount circuit breakers with magnetic-hydraulic delay protection. The mechanical and electrical interfaces are equivalent, enabling direct substitution in panel mount applications.

Q: What is the significance of the 65V DC rating on the APL1-1-60-203?

A: The 65V DC rating specifies the maximum DC voltage the original part can safely interrupt. The W91-X1110-20 specification does not explicitly list a DC voltage rating in the provided data. Verify DC application requirements against the W91-X1110-20 datasheet if DC operation is required.

Q: Why is the APL1-1-60-203 classified as obsolete?

A: Obsolete status indicates the manufacturer (Sensata-Airpax) has discontinued production. No future stock or technical updates are available from the original manufacturer. The W91-X1110-20 provides an active alternative from TE Connectivity Potter & Brumfield Relays.

Q: Are there packaging differences between these parts?

A: The APL1-1-60-203 packaging is not specified in the provided data. The W91-X1110-20 is supplied in bulk packaging. Confirm packaging requirements for your application before procurement.

Q: Does RoHS Compliance affect substitution suitability?

A: The W91-X1110-20 is RoHS Compliant, meeting current environmental regulations. If your application or region requires RoHS compliance, the W91-X1110-20 satisfies this requirement. The original part's RoHS status is not specified.

Q: What is the inventory status for each part?

A: The APL1-1-60-203 has 693 pcs in stock (new original, obsolete status). The W91-X1110-20 has 861 pcs in stock (new original, active status). For long-term availability, the W91-X1110-20 is the preferred choice due to active manufacturing.
