Equivalent & Substitute Parts for C7050AFBR

Part Overview

The C7050AFBR is a DPST pushbutton switch manufactured by Bulgin, rated for 16A at 250V AC. This panel-mount, snap-in switch features a red round button actuator with quick connect 0.250" (6.3mm) termination and IP40 ingress protection. The product is active and ROHS3 compliant. Substitute parts are identified when equivalent electrical ratings, mechanical mounting compatibility, and circuit configuration requirements necessitate alternative sourcing due to inventory constraints or application-specific needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C7050AFBR is determined by the following critical parameters:

Electrical Compatibility: Circuit configuration (DPST), current rating, and voltage rating must support the intended application. The substitute part KFB3ALA2RBB operates at 10A AC/DC with 125V AC and 28V DC ratings, representing a reduced electrical capacity compared to the main part.

Mechanical Compatibility: Panel mount snap-in mounting type and round button actuator type are required. The substitute maintains these characteristics but features a smaller panel cutout diameter (20.20mm versus 25.00mm), requiring panel modification for installation.

Termination Compatibility: Quick connect termination is maintained in the substitute, though the connector size differs (0.187" versus 0.250"), necessitating harness or connector adaptation.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

The C7050AFBR remains the primary selection for applications requiring 16A at 250V AC with standard non-illuminated operation and IP40 environmental protection. Both the main part and substitute KFB3ALA2RBB maintain active product status and ROHS3 compliance, ensuring regulatory alignment for new designs and production continuity.

Selection of the KFB3ALA2RBB substitute is appropriate only when application electrical requirements do not exceed 10A at 125V AC or 28V DC. The substitute provides enhanced ingress protection (IP65 versus IP40) and includes neon illumination capability, which may be advantageous in certain panel applications. However, the reduced electrical ratings, smaller panel cutout diameter, and different termination connector size require design verification and potential panel modification before implementation.

Frequently Asked Questions (FAQ)

Q: Can KFB3ALA2RBB directly replace C7050AFBR in existing designs?

A: Direct replacement is not recommended without design review. The substitute has lower electrical ratings (10A/125V AC versus 16A/250V AC), a smaller panel cutout (20.20mm versus 25.00mm), and different termination connector size (0.187" versus 0.250"). Panel modification and harness adaptation are required.

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

A: The C7050AFBR is rated for 16A at 250V AC. The KFB3ALA2RBB is rated for 10A at 125V AC or 28V DC. Applications exceeding 10A or 125V AC cannot use the substitute without exceeding component ratings.

Q: Does the illumination feature of KFB3ALA2RBB affect substitution compatibility?

A: The illumination feature (neon, red at 110 VAC) is an additional capability that does not prevent substitution in non-illuminated applications. However, the illumination circuit must be managed in the design if the substitute is selected.

Q: Are both parts compliant with current regulations?

A: Yes. Both C7050AFBR and KFB3ALA2RBB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What panel modifications are necessary for KFB3ALA2RBB installation?

A: The panel cutout diameter must be reduced from 25.00mm to 20.20mm. Additionally, the quick connect termination connector size differs (0.187" versus 0.250"), requiring harness connector adaptation or replacement.
