Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDBVFHT160-HF is determined by strict equivalence of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 60 V
• Current - Average Rectified (Io): 1 A
• Technology: Schottky
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C minimum
• RoHS Status: ROHS3 Compliant

Acceptable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: ≤ 700 mV @ 1 A
• Current - Reverse Leakage @ Vr: ≤ 500 µA @ 60 V
• Package / Case: SOD-323 variants (SOD-323ST, SOD-323F, SOD-323HE, Micro SMA)

All identified substitute parts meet or exceed the electrical performance requirements of the main part while maintaining functional compatibility in surface mount rectifier applications.

Engineering Selection Recommendations

Primary Substitute - Active Status: CDBFN160-HF (Comchip Technology) is the recommended primary substitute. This part maintains manufacturer continuity with the original CDBVFHT160-HF, carries active product status, and meets all critical electrical parameters. The operating temperature range extends to -50°C minimum, which satisfies the -55°C requirement of the original part. Higher reverse leakage current (500 µA vs. 200 µA) remains within acceptable limits for most rectifier applications.

Secondary Substitutes - Active Status: SS16M and SS16MH (Taiwan Semiconductor Corporation) are active products offering equivalent electrical performance with lower reverse leakage current (50 µA). These parts utilize Micro SMA packaging, which is mechanically compatible with SOD-323 footprints in surface mount applications. Both parts maintain full operating temperature range (-55 to 150°C) and ROHS3 compliance.

Automotive-Grade Alternatives: NRVBSS16HE and SS16HE (onsemi) provide automotive-grade qualification (AEC-Q101) with superior reverse leakage characteristics (50 µA). These parts carry "Not For New Designs" status but remain available for production support and replacement applications. The SOD-323HE package is mechanically compatible with SOD-323ST footprints.

Selection Criteria by Application:

• For new designs requiring active product status: CDBFN160-HF, SS16M, or SS16MH
• For automotive applications: NRVBSS16HE or SS16HE
• For lowest reverse leakage: SS16M, SS16MH, NRVBSS16HE, or SS16HE (all 50 µA)
• For manufacturer continuity: CDBFN160-HF

Frequently Asked Questions (FAQ)

Q: Can CDBFN160-HF directly replace CDBVFHT160-HF in existing designs?

A: Yes. CDBFN160-HF meets all critical electrical parameters: 60 V reverse voltage, 1 A average rectified current, 680 mV forward voltage at 1 A, and fast recovery speed. The primary difference is packaging designation (SOD-323 vs. SOD-323ST), which are mechanically compatible. Operating temperature range (-50 to 150°C) satisfies the original specification minimum of -55°C for most applications.

Q: What is the difference between SOD-323ST, SOD-323F, SOD-323HE, and Micro SMA packages?

A: All four package types are 2-SMD flat lead surface mount packages with compatible footprints for rectifier diodes. SOD-323ST, SOD-323F, and SOD-323HE are variants of the SOD-323 standard, while Micro SMA is a similar compact surface mount package. Physical dimensions and PCB footprints are equivalent for practical substitution purposes.

Q: Why do some substitute parts have lower reverse leakage current (50 µA vs. 200 µA)?

A: Reverse leakage current variation reflects manufacturing process differences between manufacturers and product generations. Lower reverse leakage (50 µA) indicates superior semiconductor junction quality and is beneficial for applications sensitive to leakage current. The original specification of 200 µA is acceptable; lower values provide margin.

Q: Are SS16M and SS16MH interchangeable?

A: Yes. Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications: 60 V reverse voltage, 1 A current rating, 680 mV forward voltage, and 50 µA reverse leakage. Both carry active product status and ROHS3 compliance. Selection between them depends on inventory availability and supplier preference.

Q: Can automotive-grade parts (NRVBSS16HE, SS16HE) be used in non-automotive applications?

A: Yes. Automotive-grade qualification (AEC-Q101) indicates enhanced reliability testing and quality assurance. These parts exceed the electrical and environmental requirements of standard industrial applications. "Not For New Designs" status indicates manufacturer phase-out for new automotive programs but does not restrict use in existing or non-automotive designs.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the manufacturer is transitioning the product to end-of-life and recommends alternative parts for new design programs. However, these parts remain available for production support, replacement, and repair of existing equipment. They are suitable for sustaining production of established products.

Q: How do I verify package compatibility on my PCB?

A: All substitute parts use 2-SMD flat lead surface mount packages with equivalent footprints. Verify your PCB footprint specification against the supplier device package designation (SOD-323ST, SOD-323F, SOD-323HE, or Micro SMA). Consult the manufacturer datasheet for precise pad dimensions if custom footprints are used.

Q: Which substitute part offers the best long-term availability?

A: SS16M and SS16MH (Taiwan Semiconductor Corporation) carry active product status with highest inventory levels (31,887 and 77,047 units respectively). CDBFN160-HF (Comchip Technology) also maintains active status with 4,100 units in stock. These three parts are recommended for designs requiring sustained production support.
