AM1704K Equivalent & Substitute Parts

Part Overview

The AM1704K is a snap action switch manufactured by Panasonic Electric Works, featuring SPDT (Single Pole Double Throw) circuit configuration with on-momentary switch function. This component is rated for 10A AC at 125V and includes a lever roller actuator with chassis mount termination. The product is currently obsolete, making identification of compatible substitute components essential for system maintenance, repair, and redesign applications.

Substitute Part Grouping Explanation

Substitution of the AM1704K is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Both main and substitute parts must maintain SPDT topology to preserve electrical functionality
• Switch Function: On-momentary operation must be preserved for control logic compatibility
• Mounting Interface: Chassis mount with screw terminal termination ensures mechanical and electrical compatibility
• Actuator Type: Lever roller actuator maintains consistent operator interface and actuation characteristics
• Voltage Rating: Minimum 125V AC/DC rating required for direct substitution
• Current Capacity: Substitute must meet or exceed 10A AC rating at 125V

The BZ-2RW82255-A2-S qualifies as a direct substitute based on matching circuit configuration, switch function, mounting type, termination style, and actuator type. The substitute exceeds the original current rating (15A AC vs. 10A AC) and voltage specifications, providing enhanced electrical capacity within the same mechanical envelope.

Engineering Selection Recommendations

The BZ-2RW82255-A2-S represents a functionally equivalent substitute for the obsolete AM1704K. Selection is based on the following engineering criteria:

Functional Equivalence: Both components share identical circuit topology (SPDT), switch function (on-momentary), mechanical interface (chassis mount with screw terminals), and actuator configuration (lever roller). These parameters ensure direct functional replacement without circuit redesign.

Electrical Compatibility: The substitute meets all voltage and current requirements of the original specification. The 15A AC rating at 125V exceeds the 10A requirement, providing operational margin within the same electrical envelope.

Product Status and Compliance: The BZ-2RW82255-A2-S is an active product with RoHS compliance certification, ensuring long-term availability and regulatory alignment. The original AM1704K is obsolete, making this substitute the appropriate selection for new designs and ongoing system support.

Environmental Performance: The substitute operates across an extended temperature range (-55°C to 85°C versus -25°C to 80°C), providing enhanced thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the BZ-2RW82255-A2-S be used as a direct replacement for the AM1704K without circuit modification?

A: Yes. Both components share identical SPDT circuit configuration, on-momentary switch function, chassis mount interface, and screw terminal termination. No circuit redesign is required.

Q: What is the significance of the higher current rating on the substitute part?

A: The BZ-2RW82255-A2-S is rated for 15A AC at 125V, compared to the AM1704K's 10A AC rating. This higher capacity provides operational margin and does not create compatibility issues in applications designed for 10A operation.

Q: Are there packaging differences between these components?

A: The AM1704K packaging is not specified in the available data. The BZ-2RW82255-A2-S is supplied in bulk packaging. Verify mechanical dimensions and mounting hole patterns against your specific application requirements.

Q: Why is the substitute part's mechanical life specification significantly higher?

A: The BZ-2RW82255-A2-S is rated for 20,000,000 mechanical cycles compared to the AM1704K's 5,000,000 cycles. This reflects improved design and manufacturing standards in the active product line and provides extended service life in high-cycle applications.

Q: Is RoHS compliance a factor in selecting this substitute?

A: The BZ-2RW82255-A2-S carries RoHS compliance certification. If your application or regulatory environment requires RoHS-compliant components, this substitute meets that requirement. The original AM1704K RoHS status is not specified.

Q: What should be verified before implementing this substitution?

A: Confirm mechanical fit within your chassis mount cavity, verify screw terminal compatibility with your wiring harness, and validate that the extended operating temperature range (-55°C to 85°C) aligns with your thermal environment.
