AVL38459 Equivalent & Substitute Parts

Part Overview

The AVL38459 is an SPDT snap action switch manufactured by Panasonic Electric Works, designed for chassis mount applications with quick connect termination. This switch is rated for 5A at 125V AC and 30V DC, featuring a lever with simulated roller actuator. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when they maintain functional compatibility across critical electrical and mechanical parameters while meeting the same circuit configuration and mounting requirements. The AVL38459 has one qualified substitute that meets these criteria.

Key Parameters

Substitute Part Grouping Explanation

The AVL38459 has one qualified substitute: the Honeywell 111SM602-H4. Substitution eligibility is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Circuit configuration: SPDT (Single Pole Double Throw)
• Switch function: On-Mom (On-Momentary)
• Current rating: 5A (AC/DC)
• Mounting type: Chassis Mount
• Actuator type: Lever with roller mechanism
• Voltage rating compatibility: Substitute must support minimum 125V AC and 30V DC

Mechanical Compatibility:

• Termination style: Quick Connect - 0.110" (2.8mm) connector compatibility
• Chassis mount footprint compatibility

The 111SM602-H4 meets all mandatory criteria with the following considerations: it provides higher AC voltage rating (250V vs. 125V), maintains 5A current capacity, supports the same DC voltage (30V), and uses compatible quick connect termination. Both parts are RoHS compliant and active in production.

Parameter Comparison

Engineering Selection Recommendations

Both the AVL38459 and 111SM602-H4 are active production parts with RoHS compliance. Selection between these parts should be based on application-specific requirements:

The AVL38459 is suitable for applications requiring lower operating force (55gf) and shorter pretravel (0.110"), making it appropriate for sensitive actuation environments within the -25°C to 85°C operating range.

The 111SM602-H4 provides extended temperature operation (-55°C to 125°C) and higher AC voltage rating (250V), offering greater margin in high-voltage applications. The higher operating force (198gf) and extended pretravel (0.218") indicate a more robust mechanical design suitable for demanding industrial environments.

Both parts maintain identical current capacity (5A), DC voltage rating (30V), mechanical life (10,000,000 cycles), and chassis mount configuration with quick connect termination compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 111SM602-H4 directly replace the AVL38459 in all applications?

A: Direct replacement is possible when the application operates within the overlapping electrical specifications (5A, 30V DC, 125V AC maximum). However, the 111SM602-H4 has higher operating force (198gf vs. 55gf) and extended pretravel (0.218" vs. 0.110"), which may affect actuation feel and mechanical integration. Physical mounting compatibility must be verified for chassis mount footprint alignment.

Q: What are the key differences in mechanical characteristics?

A: The AVL38459 features lower operating force and shorter pretravel, providing lighter actuation. The 111SM602-H4 requires greater force to actuate and has longer pretravel distance, indicating a more robust mechanical design. Operating position differs by approximately 0.1" (2.6mm), which may impact mechanical linkage design.

Q: Are both parts suitable for the same temperature range?

A: The AVL38459 operates from -25°C to 85°C, while the 111SM602-H4 extends to -55°C to 125°C. The Honeywell part provides wider temperature coverage and is suitable for applications requiring operation outside the Panasonic part's range.

Q: What termination options are available?

A: The AVL38459 uses Quick Connect - 0.110" (2.8mm) termination. The 111SM602-H4 offers both Solder and Quick Connect - 0.110" (2.8mm) termination options, providing greater flexibility in circuit board integration methods.

Q: Are both parts RoHS compliant?

A: Yes, both the AVL38459 and 111SM602-H4 are RoHS compliant and suitable for applications requiring environmental compliance.
