Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DB1C-C1AA is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain electrical functionality
• Switch Function: Must support On-Momentary operation
• Current Rating (AC): Minimum 5A at 125V AC to meet load requirements
• Actuator Type: Round pin plunger for mechanical compatibility
• Mounting Type: Through hole configuration for PCB integration
• Termination Style: PC pin for solder connection compatibility
• Operating Force: 150gf nominal for consistent actuation feel
• Operating Position: 0.330" (8.4mm) for mechanical clearance and travel distance
• RoHS Compliance: ROHS3 status for regulatory alignment

The AVL34053 manufactured by Panasonic Electric Works meets these core substitution criteria with equivalent SPDT configuration, 5A AC rating at 125V, round pin plunger actuator, through-hole mounting, PC pin termination, 150gf operating force, and matching 0.330" operating position. Both parts maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both DB1C-C1AA and AVL34053 are active production parts with full ROHS3 compliance and MSL 1 rating, ensuring regulatory alignment and environmental stability. Selection between these parts should be based on application-specific requirements:

The DB1C-C1AA provides extended operating temperature range (-40°C to 120°C) and higher DC voltage capability (48V), making it suitable for industrial applications requiring broader thermal performance. The AVL34053 offers superior electrical life (50,000 cycles versus 6,000 cycles) and higher DC current rating (5A), advantageous for high-cycle consumer and commercial applications operating within its -25°C to 85°C temperature window.

Both parts maintain identical AC ratings (5A at 125V), actuator geometry, mounting configuration, and termination style, ensuring mechanical and electrical interchangeability within their respective operational envelopes.

Frequently Asked Questions (FAQ)

Q: Can AVL34053 replace DB1C-C1AA in all applications?

A: AVL34053 is electrically and mechanically compatible for AC-rated applications at 5A/125V. However, applications requiring DC operation above 30V or temperatures below -25°C or above 85°C must use DB1C-C1AA.

Q: What are the key differences between these parts?

A: Primary differences include operating temperature range (DB1C-C1AA: -40°C to 120°C; AVL34053: -25°C to 85°C), DC voltage rating (DB1C-C1AA: 48V; AVL34053: 30V), and electrical life (DB1C-C1AA: 6,000 cycles; AVL34053: 50,000 cycles). AC ratings and mechanical specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes, both DB1C-C1AA and AVL34053 are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: Do these switches have identical mounting footprints?

A: Yes, both parts feature through-hole mounting with PC pin termination and identical operating position of 0.330" (8.4mm), ensuring direct PCB compatibility.

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

A: AVL34053 is specified for 50,000 electrical cycles compared to 6,000 cycles for DB1C-C1AA, making it suitable for applications requiring extended electrical life within its operational temperature and voltage parameters.
