AVT3234613 Equivalent & Substitute Parts

Part Overview

The AVT3234613 is a snap-action SPDT switch manufactured by Panasonic Electric Works, designed for chassis mount applications with solder lug termination. This switch is rated for 100mA at 125V AC and 30V DC, featuring a straight lever actuator with on-momentary function. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges for SPDT snap-action switches in chassis mount configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AVT3234613 is determined by the following core parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Voltage ratings must meet or exceed 125V AC and 30V DC
• Current rating must support minimum 100mA operation
• Mounting type must be Chassis Mount
• Termination style must be compatible with solder connection methods
• RoHS compliance status must match or exceed the original specification

The Honeywell 311SM778-T meets these substitution criteria with higher current capacity (1A), equivalent voltage ratings, and compatible chassis mount configuration with solder termination capability.

Parameter Comparison

Engineering Selection Recommendations

The AVT3234613 is the preferred selection for new designs due to its active product status and current manufacturing availability. The part maintains full RoHS compliance and is supported by Panasonic Electric Works with 1036 units in current inventory.

The Honeywell 311SM778-T serves as a functional equivalent for applications requiring higher current capacity (1A versus 100mA) or extended operating temperature range (-55°C to 125°C versus -25°C to 85°C). However, this substitute carries obsolete product status, limiting long-term supply availability. The 311SM778-T features significantly higher mechanical life (10,000,000 cycles) compared to the AVT3234613 (500,000 cycles), making it suitable for high-cycle applications where the extended temperature range is required.

Termination style differences (Solder Lug versus Solder Turret) require PCB layout verification to ensure mechanical and electrical compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Honeywell 311SM778-T directly replace the AVT3234613 in existing designs?

A: Functional substitution is possible when the application requirements align with the Honeywell part's specifications. The higher current rating (1A) and extended temperature range (-55°C to 125°C) provide additional operational margin. However, the different termination style (Solder Turret versus Solder Lug) requires PCB footprint verification before implementation.

Q: What is the primary limitation of using the Honeywell 311SM778-T as a substitute?

A: The Honeywell 311SM778-T carries obsolete product status, indicating discontinued manufacturing. This limits supply availability and future procurement options. For new designs, the active AVT3234613 is the recommended choice.

Q: Are both parts RoHS compliant?

A: Yes. Both the AVT3234613 and 311SM778-T maintain RoHS compliance status, meeting environmental and regulatory requirements for equivalent applications.

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

A: The AVT3234613 features a straight lever actuator with 25gf operating force and 500,000 cycle mechanical life. The 311SM778-T uses a simulated roller lever with 12gf operating force and 10,000,000 cycle mechanical life. The lower operating force and significantly higher cycle rating of the Honeywell part make it suitable for high-frequency switching applications.

Q: How do the operating temperature ranges affect substitution decisions?

A: The AVT3234613 operates from -25°C to 85°C, suitable for standard industrial and consumer applications. The 311SM778-T extends this range to -55°C to 125°C, enabling use in extreme temperature environments. Selection depends on the specific thermal requirements of the target application.
