AM1744K Equivalent & Substitute Parts

Part Overview

The AM1744K is a snap action switch manufactured by Panasonic Electric Works, configured as a single-pole double-throw (SPDT) device with a 15A AC rating at 125V. This component features a lever roller actuator and chassis mount configuration with screw terminal termination. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for system maintenance, repair, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM1744K is determined by strict equivalence across the following electrical and mechanical parameters:

• Circuit configuration: SPDT topology
• Switch function: On-Momentary operation
• Current rating: 15A minimum at AC
• Voltage rating: 125V AC minimum
• Actuator type: Lever with roller mechanism
• Mounting configuration: Chassis mount
• Termination: Screw terminal connection

The BZ-2RW825-A2 manufactured by Honeywell Sensing and Productivity Solutions satisfies all substitution criteria. This part maintains identical electrical specifications, mechanical interface requirements, and operational characteristics necessary for direct replacement in applications originally designed for the AM1744K.

Parameter Comparison

Engineering Selection Recommendations

The BZ-2RW825-A2 is the qualified substitute for the obsolete AM1744K. Both components share identical electrical ratings, circuit topology, and mechanical interface specifications. The Honeywell part carries active product status with RoHS compliance certification, providing supply chain continuity and regulatory alignment for applications requiring environmental standards adherence.

Selection of the BZ-2RW825-A2 is appropriate for direct replacement in existing designs without circuit modification or mechanical redesign. The extended operating temperature range and documented mechanical life cycle of the Honeywell component provide additional performance data for system reliability assessment.

Frequently Asked Questions (FAQ)

Q: Can the BZ-2RW825-A2 directly replace the AM1744K without modification?

A: Yes. Both components meet identical electrical specifications (15A at 125V AC, SPDT configuration, On-Momentary function), share the same mechanical interface (chassis mount, lever roller actuator, screw terminal), and maintain equivalent moisture sensitivity ratings. Direct substitution is possible without circuit or mechanical changes.

Q: What is the primary reason for seeking a substitute for the AM1744K?

A: The AM1744K is classified as obsolete. The BZ-2RW825-A2 provides functional equivalence with active manufacturing status, ensuring long-term component availability.

Q: Are there packaging differences between these parts?

A: The AM1744K packaging specification is not provided in the technical data. The BZ-2RW825-A2 is supplied in bulk packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: Does the BZ-2RW825-A2 offer additional capabilities beyond the AM1744K?

A: The BZ-2RW825-A2 provides documented DC voltage rating (125V), specified operating temperature range (-55°C to 85°C), mechanical life cycle data (20,000,000 cycles), and RoHS compliance certification. These specifications are not provided for the AM1744K but do not alter the substitution relationship for standard AC applications.

Q: What certifications apply to the substitute part?

A: The BZ-2RW825-A2 carries RoHS Compliant status and is classified under ECCN EAR99 for export control purposes. Both parts share identical HTSUS commodity codes and moisture sensitivity levels.
