AM1704F Equivalent & Substitute Parts

Part Overview

The AM1704F is a snap action switch manufactured by Panasonic Electric Works, featuring SPDT (Single Pole Double Throw) circuit configuration with 10A AC and 500mA DC current ratings at 125V. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The switch is designed for chassis mount applications with screw terminal connections and lever/roller actuator options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM1704F is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain electrical functionality
• Switch Function: Must be On-Momentary to preserve operational behavior
• Voltage Rating (AC): Minimum 125V AC required
• Mounting Type: Must be Chassis Mount for mechanical compatibility
• Termination Style: Must be Screw Terminal for connection compatibility

Substitute parts are classified into two categories:

Direct Substitute (BZ-2RW82255-A2-S): Meets or exceeds all critical parameters with enhanced current rating (15A AC) and extended mechanical life (20,000,000 cycles). Maintains identical voltage ratings and mounting configuration.

Similar Substitutes (Z-15GD-B, Z-15GW21-B): Meet core electrical requirements (SPDT, On-Momentary, 125V AC, Chassis Mount, Screw Terminal) with variations in actuator type, mechanical specifications, and DC voltage ratings. These parts are suitable where mechanical envelope and actuator preference allow deviation from original specifications.

Parameter Comparison

Engineering Selection Recommendations

BZ-2RW82255-A2-S is the primary substitute for AM1704F applications. This Honeywell part maintains mechanical and electrical compatibility while providing enhanced performance characteristics: increased AC current capacity (15A versus 10A), extended mechanical life (20,000,000 versus 5,000,000 cycles), and wider operating temperature range (-55°C to 85°C). The part is RoHS Compliant and currently in active production status, ensuring long-term availability and supply chain stability.

Z-15GD-B and Z-15GW21-B are suitable alternatives where design constraints permit actuator type variation. Both Omron parts are ROHS3 Compliant and active products. Z-15GD-B features a round pin plunger actuator with identical operating temperature range to the original part. Z-15GW21-B provides a straight lever actuator with mechanical life of 10,000,000 cycles. Both parts operate at reduced DC voltage (30V versus 125V), requiring verification of DC circuit compatibility before selection.

Frequently Asked Questions (FAQ)

Q: Can BZ-2RW82255-A2-S directly replace AM1704F without circuit modification?

A: Yes. BZ-2RW82255-A2-S maintains identical SPDT circuit configuration, On-Momentary function, 125V AC/DC voltage ratings, chassis mount configuration, and screw terminal termination. The increased current rating (15A AC) provides design margin without requiring circuit changes.

Q: What are the key differences between the Honeywell and Omron substitutes?

A: BZ-2RW82255-A2-S (Honeywell) maintains the lever/roller actuator configuration of the original part and preserves 125V DC voltage rating. Z-15GD-B and Z-15GW21-B (Omron) feature different actuator types (pin plunger and straight lever respectively) and operate at 30V DC maximum, requiring DC circuit verification. All three parts meet the 125V AC requirement and SPDT configuration.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. AM1704F is available in standard packaging. BZ-2RW82255-A2-S is supplied in bulk packaging. Z-15GD-B is supplied in tray packaging, while Z-15GW21-B is supplied in bulk packaging. Verify packaging compatibility with assembly and procurement processes.

Q: What compliance certifications apply to substitute parts?

A: BZ-2RW82255-A2-S is RoHS Compliant. Z-15GD-B and Z-15GW21-B are ROHS3 Compliant. Z-15GW21-B is REACH Affected; Z-15GD-B is REACH Unaffected. All parts carry EAR99 ECCN classification. Verify compliance requirements for your specific application and region.

Q: Can Z-15GD-B or Z-15GW21-B be used in applications requiring 125V DC operation?

A: No. Z-15GD-B and Z-15GW21-B are rated for 30V DC maximum. Applications requiring 125V DC operation must use BZ-2RW82255-A2-S or verify circuit redesign feasibility.

Q: What is the mechanical life advantage of substitute parts?

A: AM1704F provides 5,000,000 mechanical cycles. BZ-2RW82255-A2-S provides 20,000,000 cycles (4x improvement). Z-15GD-B provides 20,000,000 cycles. Z-15GW21-B provides 10,000,000 cycles (2x improvement). Extended mechanical life reduces replacement frequency in high-cycle applications.
