Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AVT32343-A is determined by the following criteria:

Circuit configuration must remain SPDT to maintain switching logic compatibility. Switch function must be on-momentary to preserve operational behavior. Mounting type must be chassis mount to ensure mechanical fit. Termination style must be solder lug or equivalent solder-based connection for PCB integration.

Electrical ratings are evaluated as follows: AC voltage rating must meet or exceed 125V; DC voltage rating must meet or exceed 30V. Current rating must support at least 3A at the specified voltage levels. Operating temperature range should encompass or extend the -25°C to 85°C specification.

The 341SM2-T from Honeywell Sensing and Productivity Solutions meets these substitution criteria with SPDT circuit, on-momentary function, chassis mount configuration, and solder turret termination. The 341SM2-T provides higher current capacity (11A AC, 5A DC) and voltage rating (250V AC), with extended operating temperature range (-55°C to 125°C), making it suitable for applications requiring the AVT32343-A specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AVT32343-A and 341SM2-T are active production parts with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Selection between these parts depends on application-specific electrical and environmental requirements.

The AVT32343-A is suitable for applications operating within 125V AC and 30V DC at 3A maximum current, with operating temperatures between -25°C and 85°C. This part provides the specified baseline performance for standard industrial switching applications.

The 341SM2-T is suitable for applications requiring higher current capacity or voltage headroom. The 11A AC rating and 250V AC voltage rating provide margin for applications with higher power demands. The extended operating temperature range (-55°C to 125°C) accommodates more demanding thermal environments. Termination style differs (solder turret versus solder lug), requiring verification of PCB pad compatibility during design integration.

Both parts maintain SPDT circuit configuration and on-momentary function, ensuring functional equivalence in switching logic.

Frequently Asked Questions (FAQ)

Q: Can the 341SM2-T directly replace the AVT32343-A in existing designs?

A: Functional substitution is possible when application requirements do not exceed the AVT32343-A electrical ratings. The 341SM2-T provides higher current and voltage capacity, making it suitable for equivalent or upgraded applications. Termination style differs (solder turret versus solder lug), requiring PCB pad layout verification before implementation.

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

A: Both switches share SPDT circuit configuration, on-momentary function, straight lever actuator, and chassis mount design. The 341SM2-T provides higher current rating (11A AC versus 3A AC), higher AC voltage rating (250V versus 125V), extended operating temperature range (-55°C to 125°C versus -25°C to 85°C), and different termination style (solder turret versus solder lug).

Q: Are both parts RoHS compliant?

A: Yes, both the AVT32343-A and 341SM2-T are RoHS compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Which part should be selected for high-temperature applications?

A: The 341SM2-T supports operating temperatures up to 125°C, compared to 85°C maximum for the AVT32343-A. For applications exceeding 85°C, the 341SM2-T is the appropriate selection.

Q: Does termination style affect mechanical fit?

A: Termination style (solder lug versus solder turret) affects PCB pad design and soldering process. Both styles are solder-based connections suitable for through-hole PCB assembly. Pad layout and hole diameter specifications must be verified against component datasheets during design integration.
