Substitute Part Grouping Explanation

Substitute parts for the CDBHA15150-HF are identified based on strict parametric equivalence across the following critical specifications:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 15 A
• Voltage - Forward (Vf) (Max) @ If: 850 mV @ 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky

Mechanical Parameters (Must Match):

• Package / Case: TO-277, 3-PowerDFN
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in reverse leakage current, packaging format (tape & reel versus cut tape), and product status do not disqualify substitution eligibility when all primary electrical and mechanical parameters align.

Engineering Selection Recommendations

CDBHA15150-HF (Primary Selection for New Designs)

The CDBHA15150-HF is the recommended selection for new circuit designs. This part carries Active product status, indicating full manufacturer support, ongoing production, and long-term availability. It meets all ROHS3 compliance requirements and carries unlimited moisture sensitivity classification, suitable for standard manufacturing and storage conditions.

FSV15150V (Substitute for Existing Designs)

The FSV15150V from onsemi is a parametric equivalent substitute that matches all critical electrical and mechanical specifications. However, this part is designated as Not For New Designs, indicating that onsemi has discontinued active development and support for this component. The FSV15150V is suitable for replacement, repair, and maintenance of existing systems where the CDBHA15150-HF may be unavailable. The lower reverse leakage current (30 µA versus 250 µA) represents an improvement in leakage performance and does not restrict substitution eligibility.

Both parts are ROHS3 compliant, operate across the identical temperature range, and are housed in mechanically compatible TO-277, 3-PowerDFN surface mount packages. Selection between these parts should be based on availability, supply chain requirements, and design phase (new versus existing).

Frequently Asked Questions (FAQ)

Q: Can FSV15150V be used as a direct replacement for CDBHA15150-HF in new designs?

A: FSV15150V meets all parametric requirements for electrical and mechanical compatibility. However, onsemi has designated this part as Not For New Designs. For new circuit development, CDBHA15150-HF is the appropriate selection due to its Active product status and manufacturer support commitment.

Q: What is the significance of the difference in reverse leakage current between these parts?

A: CDBHA15150-HF specifies 250 µA reverse leakage at 150 V, while FSV15150V specifies 30 µA at the same conditions. The lower leakage in FSV15150V represents superior performance and does not prevent substitution. Both values fall within acceptable ranges for Schottky rectifier applications at this voltage and current rating.

Q: Are the TO-277B and TO-277-3 packages mechanically interchangeable?

A: Both designations refer to the same TO-277, 3-PowerDFN package family. The suffixes (B and -3) represent manufacturer-specific package designations from Comchip Technology and onsemi respectively. The physical dimensions, pin configuration, and mounting footprint are identical, ensuring mechanical and electrical interchangeability on PCB assemblies.

Q: What is the difference between Tape & Reel and Cut Tape packaging formats?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® packaging supplies components in shorter tape segments or alternative formats, suitable for lower-volume orders or manual assembly. Both formats contain identical components; the difference is in supply and handling format only.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both CDBHA15150-HF and FSV15150V operate across the identical junction temperature range of -55°C to 150°C, ensuring thermal compatibility in all specified application environments.

Q: What does ROHS3 Compliant status indicate?

A: ROHS3 Compliant indicates that both parts meet the Restriction of Hazardous Substances Directive 3 requirements, confirming the absence of restricted materials including lead, cadmium, mercury, hexavalent chromium, and specified brominated flame retardants. This certification is required for most commercial and industrial applications.

Q: Can these parts be substituted in existing PCB designs without layout modifications?

A: Yes. Both parts share identical package geometry (TO-277, 3-PowerDFN) and pin configuration, allowing direct substitution on existing PCB layouts without footprint or routing changes.
