Substitute Part Grouping Explanation

Substitution of the B220A-13 is determined by strict equivalence across all critical electrical parameters: reverse voltage rating (20 V), average rectified current (2 A), forward voltage drop (500 mV @ 2 A), reverse leakage current (500 µA @ 20 V), and fast recovery speed characteristics. Mechanical compatibility requires identical package designation (DO-214AC, SMA) and surface mount configuration. All identified substitutes maintain these specifications without deviation.

The substitute parts are grouped by packaging format and product status:

Packaging Variants: Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) configurations provide alternative supply formats for the same electrical device.

Product Status: Active substitutes replace the discontinued B220A-13, ensuring continued availability for new designs and production requirements.

Compliance Differences: Substitute parts include RoHS3 compliance certification, whereas the original B220A-13 is RoHS non-compliant. The B220AQ-13-F variant includes automotive-grade qualification (AEC-Q101).

Engineering Selection Recommendations

B220A-13-F is the direct parametric equivalent for applications requiring standard industrial-grade Schottky diodes. This variant is active in production, RoHS3 compliant, and available in Cut Tape and Digi-Reel packaging formats. Selection of this substitute eliminates obsolescence risk while maintaining full electrical and mechanical compatibility.

B220AQ-13-F is the appropriate selection for automotive applications or designs requiring AEC-Q101 qualification. This variant meets automotive-grade standards and is RoHS3 compliant. The capacitance measurement point differs (40V versus 4V), reflecting automotive-grade characterization practices, while all other electrical parameters remain identical.

Both substitutes provide superior compliance status compared to the discontinued B220A-13, with RoHS3 certification suitable for modern supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can B220A-13-F and B220AQ-13-F be used interchangeably with B220A-13?

A: Both substitutes are parametrically equivalent to B220A-13 across all critical electrical specifications: 20 V reverse voltage, 2 A average rectified current, 500 mV forward voltage drop, and fast recovery characteristics. Direct substitution is supported for identical circuit performance. Selection between the two substitutes depends on packaging requirements and compliance certifications.

Q: What is the difference between B220A-13-F and B220AQ-13-F?

A: Both parts share identical electrical ratings and package configuration. B220A-13-F is standard industrial-grade with Cut Tape and Digi-Reel packaging options. B220AQ-13-F is automotive-grade with AEC-Q101 qualification, supplied in Tape & Reel format. The capacitance measurement point differs (4V versus 40V), reflecting automotive characterization standards. Selection depends on application requirements and supply format needs.

Q: Why does B220AQ-13-F show capacitance at 40V instead of 4V?

A: Automotive-grade components follow different characterization standards. The 40V measurement point for B220AQ-13-F reflects AEC-Q101 qualification practices. This does not indicate a functional difference; both measurements characterize the same diode under different test conditions specified by their respective qualification standards.

Q: Are there packaging differences between the substitutes?

A: B220A-13-F is available in Cut Tape (CT) & Digi-Reel® packaging. B220AQ-13-F is supplied in Tape & Reel (TR) format. Both use identical DO-214AC, SMA surface mount packages. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Is RoHS3 compliance required for my application?

A: The original B220A-13 is RoHS non-compliant. Both substitutes (B220A-13-F and B220AQ-13-F) are RoHS3 compliant. Modern supply chain requirements and environmental regulations typically mandate RoHS3 compliance. Substitutes provide compliance certification without electrical or mechanical changes.

Q: Can B220A-13-F be used in automotive applications?

A: B220A-13-F is standard industrial-grade and does not carry automotive qualification. For automotive applications requiring AEC-Q101 certification, B220AQ-13-F is the specified substitute. For non-safety-critical automotive applications, B220A-13-F may be acceptable depending on design requirements and customer specifications.

Q: What is the inventory status of these substitutes?

A: B220A-13-F has 21,767 pieces in stock. B220AQ-13-F has 20,100 pieces in stock. Both substitutes are active production items with established supply availability, eliminating obsolescence concerns associated with the discontinued B220A-13.
