Substitute Part Grouping Explanation

Substitution of the AM1105F is based on functional equivalence in snap action switch design. The primary substitute identified is the BZ-2RS from Honeywell Sensing and Productivity Solutions. This substitution is valid based on the following criteria:

• Both components function as snap action switches with defined switching characteristics
• Electrical performance parameters (current and voltage ratings) are compatible with typical snap action switch applications
• Mechanical life specifications (20,000,000 cycles for BZ-2RS) provide equivalent operational durability
• Moisture sensitivity classification (MSL 1) matches the original component
• Both components meet industrial switching requirements with defined actuator and mounting specifications

Parameter Comparison

Engineering Selection Recommendations

The BZ-2RS represents an active production alternative to the obsolete AM1105F. Selection of the BZ-2RS is supported by:

• Active product status ensures ongoing availability and supply chain reliability
• RoHS compliance certification meets current environmental and regulatory standards
• Matching moisture sensitivity classification (MSL 1) maintains compatibility with storage and handling requirements
• Defined electrical and mechanical specifications provide measurable performance parameters for system integration

Physical mounting and electrical interface compatibility must be verified against the specific application circuit and mechanical enclosure design before implementation.

Frequently Asked Questions (FAQ)

Q: Why is the AM1105F listed as obsolete? A: The AM1105F has been discontinued by Panasonic Electric Works. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed.

Q: What makes the BZ-2RS a suitable substitute for the AM1105F? A: Both components are snap action switches with equivalent moisture sensitivity classification. The BZ-2RS provides defined electrical ratings (15A AC at 125V, 500mA DC at 125V) and mechanical durability (20,000,000 cycles), supporting functional replacement in snap action switch applications.

Q: Are there packaging differences between AM1105F and BZ-2RS? A: The AM1105F packaging is not specified in available documentation. The BZ-2RS is supplied in bulk packaging. Packaging compatibility must be evaluated based on application requirements and assembly processes.

Q: Does the BZ-2RS require circuit modifications? A: The BZ-2RS is configured as SPDT (Single Pole Double Throw) with defined switch function and termination style (solder lug). Circuit compatibility depends on the original AM1105F circuit configuration and application requirements. Physical mounting interface must also be verified.

Q: What is the operating temperature range for the BZ-2RS? A: The BZ-2RS operates across -55°C to 85°C. Verify this range meets the thermal requirements of the target application.

Q: Is the BZ-2RS RoHS compliant? A: Yes, the BZ-2RS is RoHS compliant, meeting current environmental standards for electronic component manufacturing and use.
