AVT3404619 Equivalent & Substitute Parts

Part Overview

The AVT3404619 is a snap-action switch manufactured by Panasonic Electric Works, configured as a Single Pole Double Throw (SPDT) momentary contact switch. This through-hole mounted component is designed for low-current applications requiring reliable switching action with a 0.1A (100mA) current rating at 125V AC or 30V DC. The part is currently active in production and RoHS compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for SPDT snap-action switches.

Key Parameters

Substitute Part Grouping Explanation

The DB1C-C1AA from ZF Electronics qualifies as a substitute based on the following allowed parameter alignment:

Matching Parameters:

• Circuit configuration: Both are SPDT switches
• Switch function: Both are On-Momentary contact types
• Actuator type: Both use round pin plunger actuation
• Mounting type: Both are through-hole mounted
• Termination style: Both use PC pin termination
• Voltage rating (AC): Both rated at 125V AC
• Operating position: Both at 0.330" (8.4mm)
• Differential travel: Both at 0.004" (0.1mm)
• RoHS compliance: Both meet RoHS standards
• MSL rating: Both at MSL 1 (Unlimited)

Differing Parameters: The DB1C-C1AA has higher current capacity (5A AC / 1A DC versus 100mA), higher DC voltage rating (48V versus 30V), and extended operating temperature range (-40°C to 120°C versus -25°C to 85°C). These differences represent enhanced capabilities rather than limitations, making the substitute suitable for applications within the original part's electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the AVT3404619 and DB1C-C1AA are active production components with current RoHS compliance certifications. The AVT3404619 is suitable for applications requiring the specified 100mA current and 30V DC maximum voltage. The DB1C-C1AA can be selected when higher current capacity or extended temperature operation is required within the same 125V AC voltage class and through-hole mounting footprint. Both parts share identical operating position and differential travel characteristics, ensuring mechanical compatibility in standard snap-action switch applications. Selection between these parts depends on the specific current and voltage requirements of the target application, with the DB1C-C1AA providing additional operational margin in current and temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the DB1C-C1AA replace the AVT3404619 in all applications?

A: The DB1C-C1AA is mechanically and electrically compatible for applications operating within the AVT3404619's specifications (100mA maximum current, 30V DC maximum). The substitute part's higher current and voltage ratings do not create incompatibility. However, application-specific requirements such as operating force (100gf versus 150gf) and pretravel characteristics (0.024" versus 0.040") should be evaluated for critical timing or force-sensitive applications.

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

A: Both parts share identical operating position (0.330" / 8.4mm) and differential travel (0.004" / 0.1mm). The DB1C-C1AA has greater pretravel (0.040" versus 0.024") and overtravel (0.025" versus 0.015"), along with higher operating force (150gf versus 100gf). These differences may affect actuation feel and response characteristics in sensitive applications.

Q: Are both parts suitable for RoHS-compliant assemblies?

A: Yes. The AVT3404619 is RoHS Compliant, and the DB1C-C1AA is ROHS3 Compliant. Both meet current RoHS requirements for new product designs.

Q: What is the packaging format for these parts?

A: Both the AVT3404619 and DB1C-C1AA are supplied in bulk packaging as new original stock components.

Q: How do the electrical life ratings compare?

A: The AVT3404619 is rated for 200,000 electrical cycles, while the DB1C-C1AA is rated for 6,000 electrical cycles. For applications requiring extended cycle life at the specified current levels, the AVT3404619 provides superior performance.
