AM1503F Equivalent & Substitute Parts

Part Overview

The AM1503F 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 equivalent substitutes necessary for ongoing maintenance, repair, and new design applications where legacy component sourcing is impractical.

The AM1503F operates with a lever and roller actuator mechanism, chassis mount configuration, and solder lug termination. It is cadmium-free and rated for 500,000 electrical cycles and 5,000,000 mechanical cycles across an operating temperature range of -25°C to 80°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM1503F is based on strict electrical and mechanical compatibility criteria. The following parameters must align for a valid substitute:

Critical Matching Parameters:

• Circuit configuration: SPDT (Single Pole Double Throw)
• Switch function: On-Momentary operation
• Voltage rating: 125V AC and DC minimum
• Actuator type: Lever with roller mechanism
• Mounting type: Chassis mount
• Termination style: Solder lug

Allowable Variations:

• Current rating may exceed the original specification (10A AC minimum required)
• Operating temperature range may be broader than the original
• Electrical and mechanical life cycles may differ
• Ingress protection rating may be enhanced
• Compliance certifications may be updated

The HBS2KGB4SA011C from C&K meets all critical matching parameters and is classified as an active product with enhanced electrical specifications and environmental protection ratings.

Engineering Selection Recommendations

The HBS2KGB4SA011C is a direct functional substitute for the AM1503F based on matching circuit topology, voltage ratings, actuator configuration, and mounting specifications. Selection should be based on the following factors:

Product Status: The AM1503F is obsolete, while the HBS2KGB4SA011C is active. Active product status ensures ongoing availability and manufacturer support.

Compliance & Certifications: The HBS2KGB4SA011C carries ROHS3 compliance and REACH affected status, meeting current regulatory requirements. The AM1503F carries cadmium-free designation.

Environmental Performance: The HBS2KGB4SA011C provides IP65 ingress protection, suitable for applications requiring dust and moisture resistance. The AM1503F does not specify ingress protection.

Electrical Specifications: The HBS2KGB4SA011C provides 20A AC current capacity, exceeding the AM1503F requirement of 10A. Both maintain 500mA DC rating and 125V voltage specifications.

Operating Range: The HBS2KGB4SA011C operates across -55°C to 150°C, providing broader temperature coverage than the AM1503F range of -25°C to 80°C.

Cycle Life Consideration: The AM1503F specifies 500,000 electrical cycles; the HBS2KGB4SA011C specifies 150,000 electrical cycles. Application duty cycle requirements should be evaluated against these specifications.

Frequently Asked Questions (FAQ)

Q: Can the HBS2KGB4SA011C directly replace the AM1503F in existing designs?

A: Yes, the HBS2KGB4SA011C is electrically and mechanically compatible. Both components share identical SPDT circuit configuration, 125V voltage rating, lever-roller actuator type, chassis mount configuration, and solder lug termination. Physical dimensions differ slightly; verify mounting hole alignment and actuator travel distances in your specific application.

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

A: The primary differences are current rating (20A vs. 10A AC), operating temperature range (-55°C to 150°C vs. -25°C to 80°C), electrical life cycles (150,000 vs. 500,000), ingress protection (IP65 vs. unspecified), and product status (active vs. obsolete). The HBS2KGB4SA011C provides enhanced environmental protection and broader temperature operation.

Q: Are there packaging differences between these parts?

A: The AM1503F is specified with dash packaging notation; the HBS2KGB4SA011C is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Which switch should I select for new designs?

A: The HBS2KGB4SA011C is recommended for new designs due to active product status, current regulatory compliance (ROHS3, REACH), and enhanced environmental specifications. The AM1503F should only be considered for legacy system maintenance where exact component matching is required.

Q: How do the mechanical specifications compare?

A: Both switches feature similar mechanical parameters: operating force approximately 100gf, release force approximately 20gf, and operating position near 1.2 inches. Minor variations exist in pretravel, differential travel, and overtravel distances. Consult detailed datasheets for precise mechanical specifications if your application has strict actuation requirements.

Q: Is the HBS2KGB4SA011C suitable for outdoor or harsh environment applications?

A: The HBS2KGB4SA011C provides IP65 ingress protection, making it suitable for dust-tight and water-resistant applications. The AM1503F does not specify ingress protection. Environmental suitability depends on specific application conditions and required protection level.
