AM1703F Equivalent & Substitute Parts

Part Overview

The AM1703F is a snap action switch manufactured by Panasonic Electric Works, featuring Single Pole Double Throw (SPDT) configuration with 10A AC and 500mA DC current capacity at 125V. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and redesign applications. The switch employs a lever-roller actuator with chassis mount configuration and screw terminal termination, designed for applications requiring reliable on-momentary switching action.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM1703F is determined by strict alignment of electrical and mechanical parameters. The primary substitute identified is the HBS2KGB4SA055C from C&K, which maintains functional equivalence through the following criteria:

Critical Matching Parameters:

• Circuit configuration: SPDT maintained
• Switch function: On-Momentary maintained
• Voltage rating: 125V AC/DC maintained
• Actuator type: Lever-Roller maintained
• Mounting type: Chassis Mount maintained
• Termination style: Screw Terminal maintained

Allowable Parameter Variations:

• Current rating: HBS2KGB4SA055C rated at 20A AC (exceeds 10A requirement, acceptable for substitution)
• Operating temperature: HBS2KGB4SA055C range -55°C to 150°C (exceeds -25°C to 80°C, acceptable for substitution)
• Mechanical characteristics: Operating position, pretravel, differential travel, and overtravel values differ within acceptable mechanical tolerances for chassis-mounted snap action switches

Parameter Comparison

Engineering Selection Recommendations

The HBS2KGB4SA055C qualifies as a functional substitute for the AM1703F based on electrical and mechanical parameter alignment. The substitute part is currently in active production status, ensuring availability for new procurement and replacement applications. The HBS2KGB4SA055C carries ROHS3 compliance and REACH affected status, meeting current regulatory requirements for electronic components in most jurisdictions. The higher current rating (20A AC versus 10A AC) and extended operating temperature range provide operational margin for the original application requirements. The reduced electrical life specification (150,000 cycles versus 500,000 cycles) should be evaluated against specific application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the HBS2KGB4SA055C directly replace the AM1703F in existing assemblies?

A: Direct mechanical and electrical substitution is supported. Both components feature identical circuit configuration (SPDT), switch function (On-Momentary), voltage rating (125V AC/DC), actuator type (Lever-Roller), mounting type (Chassis Mount), and termination style (Screw Terminal). Physical dimensions and mounting hole patterns should be verified against assembly drawings prior to implementation.

Q: What are the implications of the higher current rating on the HBS2KGB4SA055C?

A: The 20A AC rating of the substitute part exceeds the 10A AC requirement of the original component. This represents a design margin increase and does not create compatibility issues for applications operating at or below the original 10A specification.

Q: How do the electrical life specifications compare?

A: The AM1703F specifies 500,000 electrical cycles while the HBS2KGB4SA055C specifies 150,000 electrical cycles. Applications requiring extended cycle life should evaluate whether the substitute part meets specific duty cycle requirements.

Q: Are there packaging differences between these components?

A: The AM1703F is listed with dash packaging notation, while the HBS2KGB4SA055C is supplied in bulk packaging. Packaging format does not affect electrical or mechanical performance.

Q: What compliance certifications apply to the substitute part?

A: The HBS2KGB4SA055C is ROHS3 compliant and REACH affected. The original AM1703F carries Moisture Sensitivity Level 1 (Unlimited), as does the substitute part.
