Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM1704KF is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain identical switching logic
• Switch Function: Must be On-Mom (momentary) to preserve operational behavior
• Current Rating: Must support minimum 10A at 125V AC
• Actuator Type: Must feature lever-roller configuration for mechanical compatibility
• Mounting Type: Must be chassis mount with screw terminal termination
• Voltage Rating: Must meet or exceed 125V AC rating

The BZ-RW922-A2 manufactured by Honeywell Sensing and Productivity Solutions satisfies all substitution criteria. This part maintains identical circuit configuration, switch function, current and voltage ratings, actuator type, and mounting specifications. The BZ-RW922-A2 is classified as active product status, ensuring ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The BZ-RW922-A2 is the qualified substitute for the obsolete AM1704KF based on the following engineering criteria:

Functional Equivalence: Both parts maintain identical SPDT circuit configuration and momentary switch function, ensuring direct functional replacement without circuit redesign.

Electrical Ratings: The BZ-RW922-A2 meets the 10A at 125V AC requirement, with no derating necessary for standard applications.

Mechanical Interface: Chassis mount configuration with screw terminal termination provides direct mechanical and electrical interface compatibility.

Product Status and Compliance: The BZ-RW922-A2 is classified as active product, ensuring long-term supply availability. RoHS compliance certification provides regulatory alignment for applications subject to environmental standards.

Performance Enhancement: The BZ-RW922-A2 offers extended operating temperature range (-55°C to 85°C versus -25°C to 80°C) and significantly higher mechanical life rating (20,000,000 cycles versus 5,000,000 cycles), providing improved reliability margins for critical applications.

Frequently Asked Questions (FAQ)

Q: Can the BZ-RW922-A2 be used as a direct replacement for the AM1704KF without circuit modification?

A: Yes. Both parts are SPDT momentary switches with identical current and voltage ratings, actuator type, and mounting configuration. No circuit redesign is required.

Q: What are the key differences between these two parts?

A: The primary differences are product status (BZ-RW922-A2 is active versus AM1704KF obsolete), operating temperature range (BZ-RW922-A2 extends to -55°C and 85°C), mechanical life rating (BZ-RW922-A2 rated for 20,000,000 cycles), and RoHS compliance certification (BZ-RW922-A2 only).

Q: Are there mechanical dimension differences that affect mounting?

A: Both parts feature chassis mount configuration with screw terminal termination. Operating position and pretravel specifications differ slightly (AM1704KF: 1.188" operating position; BZ-RW922-A2: 1.235" operating position), but both are compatible with standard chassis mount applications.

Q: What is the packaging difference between these parts?

A: AM1704KF is supplied in standard packaging; BZ-RW922-A2 is supplied in bulk packaging. Packaging format does not affect functional or mechanical compatibility.

Q: Is the BZ-RW922-A2 suitable for applications requiring extended temperature operation?

A: The BZ-RW922-A2 supports -55°C to 85°C operating range, compared to the AM1704KF range of -25°C to 80°C. Applications requiring operation below -25°C or above 80°C should verify compatibility with the extended range specification.
