AV3602649 Equivalent & Substitute Parts

Part Overview

The Panasonic Electric Works AV3602649 is an SPDT snap-action switch designed for through-hole, right-angle mounting applications. This switch features a round pin plunger actuator and is rated for 100mA at 125V AC or 30V DC, making it suitable for low-current control circuits. The part is currently active in production with robust mechanical specifications including 500,000 mechanical life cycles and 200,000 electrical life cycles. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for this switch category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AV3602649 are evaluated based on the following critical parameters that define functional equivalence:

Primary Compatibility Criteria:

• Circuit configuration (SPDT required)
• Switch function (On-Momentary operation)
• Actuator type (Round pin plunger)
• Mounting type (Through hole, right angle)
• Termination style (PC pin)

Electrical Compatibility Criteria:

• Current rating must meet or exceed 100mA
• AC voltage rating must be 125V or higher
• DC voltage rating must be 30V or higher

Mechanical Compatibility Criteria:

• Operating position, pretravel, differential travel, and overtravel must be within acceptable tolerance ranges for PCB layout and mechanical assembly
• Operating temperature range must encompass the application requirements

The Honeywell Sensing and Productivity Solutions ZV50B50A01 shares the same circuit configuration, actuator type, mounting style, and termination method. However, this part exhibits significantly higher current capacity (6A AC versus 100mA) and different mechanical characteristics, which may affect compatibility depending on application requirements.

Parameter Comparison

Engineering Selection Recommendations

The AV3602649 remains the preferred choice for new designs due to its active product status and ROHS3 compliance. The part is currently in production with established supply chain availability.

The ZV50B50A01 is classified as obsolete and should not be selected for new applications. While this Honeywell switch maintains the same circuit topology and mounting configuration, its obsolete status creates long-term supply risk. Additionally, the significantly higher operating force (65gf versus 50gf) and different operating position (0.449" versus 0.330") may require mechanical redesign of the actuator interface and PCB layout.

For applications requiring extended temperature operation beyond -25°C to 85°C, the ZV50B50A01 offers a wider operating range (-40°C to 120°C). However, this advantage is offset by obsolescence and the mechanical parameter differences that would necessitate design validation.

Frequently Asked Questions (FAQ)

Q: Can the ZV50B50A01 directly replace the AV3602649 without PCB modification?

A: No. The operating position differs by 0.119" (3.0mm), which affects the actuator engagement depth and may require PCB layout changes. The increased operating force (65gf versus 50gf) also impacts the mechanical design of the actuator assembly.

Q: Is the ZV50B50A01 suitable for new product designs?

A: No. The part is classified as obsolete, which creates supply chain risk and limits long-term availability. New designs should use the active AV3602649 or identify alternative active-status switches.

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

A: The AV3602649 is rated for 100mA at 125V AC or 30V DC. The ZV50B50A01 is rated for 6A at 125V AC, representing a 60-fold increase in current capacity. The DC voltage rating for the Honeywell part is not specified in the available data.

Q: Are both switches RoHS compliant?

A: Yes. The AV3602649 is ROHS3 compliant, and the ZV50B50A01 is RoHS compliant. Both meet environmental compliance requirements for their respective production periods.

Q: How do the mechanical life ratings compare?

A: The AV3602649 is rated for 500,000 mechanical cycles, while the ZV50B50A01 is rated for 10,000,000 mechanical cycles. The Honeywell switch offers significantly higher mechanical durability. However, the AV3602649 provides superior electrical life at 200,000 cycles versus 10,000 cycles for the Honeywell part.

Q: What is the impact of the different operating temperature ranges?

A: The AV3602649 operates from -25°C to 85°C, while the ZV50B50A01 operates from -40°C to 120°C. Applications requiring operation below -25°C or above 85°C would require the Honeywell switch or an alternative part. However, this must be weighed against the obsolescence status.
