Equivalent & Substitute Parts for C7050AFBB

Part Overview

The C7050AFBB is a pushbutton switch manufactured by Bulgin, classified as a DPST (Double Pole Single Throw) standard panel mount, snap-in component. This switch is rated for 16A at 250V AC and features a round black button actuator with quick connect 0.250" (6.3mm) termination. The product is active and in stock with 1063 units available. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, allowing for component interchangeability in circuit designs where the primary part becomes unavailable or when alternative specifications better suit specific operational conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C7050AFBB is determined by the following critical parameters:

• Circuit Configuration: Must be DPST to maintain electrical functionality
• Switch Function: Must be On-Off operation
• Mounting Type: Must support Panel Mount, Snap-In installation
• Termination Style: Quick Connect terminals enable interchangeability
• Panel Cutout Compatibility: Physical panel opening dimensions must accommodate the substitute component
• Electrical Ratings: Current and voltage ratings must meet or exceed application requirements
• Compliance Status: RoHS3 compliance and REACH unaffected status ensure regulatory alignment

The identified substitute KFB3ALA2RBB from ZF Electronics shares the DPST circuit configuration, On-Off function, panel mount snap-in mounting, and quick connect termination. However, differences in electrical ratings, panel cutout dimensions, and additional features (illumination) require evaluation against specific application parameters.

Engineering Selection Recommendations

Both the C7050AFBB and KFB3ALA2RBB maintain active product status and ROHS3 compliance, ensuring regulatory alignment for current applications. The C7050AFBB is suitable for applications requiring 16A at 250V AC with IP40 environmental protection and standard panel mounting. The KFB3ALA2RBB provides enhanced environmental protection at IP65 rating and supports dual AC/DC operation at lower electrical ratings (10A AC/DC, 125V AC, 28V DC). Selection between these components depends on application-specific electrical requirements, environmental conditions, and panel cutout dimensions. The difference in termination connector size (0.250" versus 0.187") and panel cutout diameter (25.00mm versus 20.20mm) requires mechanical verification before substitution.

Frequently Asked Questions (FAQ)

Q: Can KFB3ALA2RBB directly replace C7050AFBB in all applications?

A: Direct replacement requires verification of three factors: electrical ratings (the substitute is rated for 10A versus 16A), panel cutout dimensions (20.20mm versus 25.00mm), and termination connector compatibility (0.187" versus 0.250"). Applications operating at or below 10A and 125V AC with compatible panel openings may use the substitute.

Q: What is the significance of the panel cutout diameter difference?

A: The C7050AFBB requires a 25.00mm circular panel opening, while the KFB3ALA2RBB requires 20.20mm. Existing panel designs must accommodate the substitute's smaller cutout, or mechanical modification is necessary.

Q: Does the termination connector size affect interchangeability?

A: Yes. The C7050AFBB uses 0.250" (6.3mm) quick connect terminals, while the KFB3ALA2RBB uses 0.187" (4.7mm) terminals. Wiring harnesses and PCB connectors must be compatible with the selected component's termination style.

Q: What is the difference in environmental protection between these components?

A: The C7050AFBB provides IP40 protection (dust and splash resistant), while the KFB3ALA2RBB provides IP65 protection (dust tight and water resistant). Applications in wet or high-moisture environments benefit from the enhanced IP65 rating of the substitute.

Q: Are both components RoHS3 compliant?

A: Yes, both C7050AFBB and KFB3ALA2RBB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.
