ACDBN160-HF Schottky Diode Equivalent & Substitute Parts

Part Overview

The ACDBN160-HF is a 60V, 1A Schottky rectifier diode manufactured by Comchip Technology in a 1206 surface mount package. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The part carries automotive-grade qualification (AEC-Q101) and is RoHS3 compliant, making substitutes subject to the same compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACDBN160-HF is determined by the following electrical and mechanical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 60 V minimum
• Technology: Schottky
• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: -55°C to 150°C minimum

Current Capacity Consideration: The ACDBN160-HF specifies 1A average rectified current. Substitute parts with equal or higher current ratings (Io ≥ 1A) are electrically compatible, as they satisfy the original circuit requirements while providing equal or improved performance margins.

Package Compatibility: The original 1206 surface mount package may be substituted with alternative surface mount packages (such as 3220/DO-214AB) provided the circuit board layout and thermal management accommodate the physical dimensions.

The identified substitute ACDBCT360-HF meets all mandatory electrical criteria and maintains automotive-grade certification, with increased current capacity (3A) and modified package geometry.

Parameter Comparison

Engineering Selection Recommendations

ACDBCT360-HF as Primary Substitute:

The ACDBCT360-HF is the manufacturer-recommended substitute for the obsolete ACDBN160-HF. Both components share identical reverse voltage ratings (60V), matching Schottky technology, and equivalent automotive-grade certifications (AEC-Q101). Both maintain ROHS3 compliance and unlimited moisture sensitivity classification.

The ACDBCT360-HF provides 3A average rectified current capacity, exceeding the original 1A specification. This increased current rating ensures compatibility with circuits designed for the ACDBN160-HF while providing additional performance margin.

Package Transition Consideration:

The substitute transitions from a 1206 surface mount package to a 3220/DO-214AB package. This change requires circuit board layout modification to accommodate the larger footprint. The 3220/DO-214AB package provides improved thermal dissipation characteristics suitable for higher current applications.

Product Status Impact:

The ACDBN160-HF is classified as obsolete, while the ACDBCT360-HF carries Last Time Buy status. This indicates limited future availability of the substitute. Long-term design strategies should consider secondary alternatives or design revision to accommodate additional substitute options.

Compliance Verification:

Both components maintain identical compliance profiles: ROHS3 compliant, REACH unaffected, and EAR99 classification. No additional regulatory documentation is required for substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can ACDBCT360-HF directly replace ACDBN160-HF in existing circuit boards?

A: Electrical substitution is valid. The ACDBCT360-HF meets all electrical requirements of the ACDBN160-HF with equal or superior performance. However, physical package substitution requires circuit board layout modification due to the transition from 1206 to 3220/DO-214AB package geometry.

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

A: The primary difference is current capacity: ACDBN160-HF is rated 1A, while ACDBCT360-HF is rated 3A. Both maintain 60V reverse voltage, identical forward voltage characteristics at their respective current ratings, and matching Schottky technology. Reverse leakage current and capacitance values differ due to the larger die size in the higher-current part.

Q: Are both parts automotive-qualified?

A: Yes. Both ACDBN160-HF and ACDBCT360-HF carry automotive-grade classification with AEC-Q101 qualification. Both are suitable for automotive applications without additional qualification testing.

Q: What is the significance of the product status change from Obsolete to Last Time Buy?

A: The ACDBN160-HF is no longer manufactured. The ACDBCT360-HF, while available as a Last Time Buy component, has limited future production. Designs should not rely indefinitely on either part number. Long-term strategies require identification of additional alternatives or design modification.

Q: Do the RoHS and REACH compliance statuses match?

A: Yes. Both components are ROHS3 compliant and REACH unaffected. No additional compliance documentation is required for substitution.

Q: How does the package change affect thermal performance?

A: The 3220/DO-214AB package provides larger surface area and improved thermal coupling compared to the 1206 package. This supports the higher 3A current rating and provides better heat dissipation in high-power applications.

Q: Are there secondary substitute options if ACDBCT360-HF becomes unavailable?

A: The ACDBCT360-HF documentation references CD214B-B360R and CD214C-B360R as additional substitutes. These alternatives maintain the same electrical specifications and automotive qualification. Detailed parameter comparison with these parts requires separate technical documentation.
