Substitute Part Grouping Explanation

Substitution of the CDBA5150-G is determined by strict equivalence across the following critical parameters:

Reverse Voltage Rating: 150V DC maximum
Forward Current Rating: 5A average rectified current
Forward Voltage Drop: 870 mV maximum at 5A
Recovery Speed: Fast Recovery ≤ 500ns, > 200mA
Reverse Leakage Current: 500 µA @ 150V
Package Type: DO-214AC (SMA) surface mount
Technology: Schottky rectifier diode
Compliance: ROHS3 Compliant, REACH Unaffected

The CDBA5150-HF meets all electrical and mechanical parameters specified for the CDBA5150-G. Both parts share identical base product number (CDBA5150) and are manufactured by Comchip Technology. The primary distinction is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and product status (Not For New Designs versus Active).

Engineering Selection Recommendations

The CDBA5150-HF is a direct parametric equivalent to the CDBA5150-G. All electrical characteristics, mechanical dimensions, thermal ratings, and regulatory compliance specifications are identical. The CDBA5150-HF holds Active product status, ensuring continued availability and manufacturer support, whereas the CDBA5150-G is designated "Not For New Designs."

For applications currently using CDBA5150-G, the CDBA5150-HF provides seamless functional replacement without circuit modification or re-qualification. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

The difference in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) does not affect electrical performance or PCB assembly compatibility. Packaging selection should be based on procurement volume and assembly line requirements.

Frequently Asked Questions (FAQ)

Q: Can CDBA5150-HF be used as a direct replacement for CDBA5150-G in existing designs?

A: Yes. The CDBA5150-HF is electrically and mechanically identical to the CDBA5150-G across all specified parameters. No circuit changes, PCB layout modifications, or design re-qualification are required. Both parts are rated for 150V reverse voltage, 5A average rectified current, and feature identical forward voltage drop, recovery speed, and thermal characteristics.

Q: What is the difference between Tape & Reel (TR) and Cut Tape & Digi-Reel® packaging?

A: Both packaging formats contain the same electronic component in DO-214AC (SMA) surface mount package. Tape & Reel (TR) is supplied on continuous reel tape suitable for high-volume automated assembly. Cut Tape & Digi-Reel® provides flexibility for lower-volume or mixed-component orders. Electrical performance and PCB assembly compatibility are identical.

Q: Why is CDBA5150-G marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory remains available for legacy system support and repair. The CDBA5150-HF, with Active status, is the recommended choice for ongoing production and new designs.

Q: Are there any compliance or certification differences between these parts?

A: No. Both CDBA5150-G and CDBA5150-HF are ROHS3 Compliant, REACH Unaffected, and carry identical MSL (Moisture Sensitivity Level) ratings of 1 (Unlimited). Regulatory and environmental compliance is equivalent.

Q: What are the critical parameters for substitution in Schottky diode applications?

A: For Schottky rectifier diodes, substitution requires matching: reverse voltage rating (150V), forward current rating (5A), forward voltage drop (870 mV @ 5A), recovery speed (≤ 500ns), reverse leakage current (500 µA @ 150V), and package type (DO-214AC). All these parameters are identical between CDBA5150-G and CDBA5150-HF.
