CDBF0230-HF Schottky Diode Equivalent & Substitute Parts

Part Overview

The CDBF0230-HF is a Schottky rectifier diode manufactured by Comchip Technology, rated for 30V DC reverse voltage with 200mA average rectified current in a 1005 surface mount package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and production continuity. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering active product status and improved supply availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 500 mV @ 200 mA
• Technology: Schottky

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: 1005 (2512 Metric)
• Supplier Device Package: 1005/SOD-323F

Compliance Equivalence Criteria:

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

All identified substitute parts meet these criteria. Variations in Current - Reverse Leakage measurement conditions (@ 10 V versus @ 30 V) and Capacitance specifications do not disqualify substitution, as these represent measurement point differences rather than functional incompatibility within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CDBF0230

CDBF0230 is the direct active equivalent of CDBF0230-HF. Both parts share identical electrical parameters, package specifications, and compliance certifications. The primary distinction is product status: CDBF0230 maintains active production status with significantly higher inventory availability (2300 pcs versus 643 pcs). This part is suitable for direct replacement in all applications where CDBF0230-HF was specified.

Secondary Substitutes: CDBFR0230 and CDBFR0230R-HF

CDBFR0230 and CDBFR0230R-HF are parametrically equivalent alternatives with active product status. Both maintain identical electrical ratings and package specifications. CDBFR0230R-HF preserves the "-HF" suffix designation present in the original part number. Selection between CDBF0230 and CDBFR0230 variants depends on existing design documentation and procurement specifications.

Tertiary Substitutes: CDBF0230L and CDBFR0230L

CDBF0230L and CDBFR0230L are functionally equivalent with one specification variance: reverse leakage current is measured at 10V rather than 30V. Both parts maintain active status and identical forward voltage, reverse voltage, and current ratings. CDBFR0230L offers the highest inventory availability (32400 pcs) among all substitutes. These parts are suitable for applications where the measurement condition difference does not impact circuit performance.

Compliance Status

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), REACH Unaffected status, and identical ECCN and HTSUS classifications as the original CDBF0230-HF.

Frequently Asked Questions (FAQ)

Q: Can CDBF0230 directly replace CDBF0230-HF in existing designs?

A: Yes. CDBF0230 is electrically and mechanically identical to CDBF0230-HF. Both parts are rated for 30V reverse voltage, 200mA average rectified current, and use the 1005/SOD-323F package. The primary difference is product status: CDBF0230 is active production while CDBF0230-HF is obsolete.

Q: What is the difference between CDBF0230 and CDBFR0230?

A: Both parts share identical electrical specifications (30V, 200mA, 500mV forward voltage) and package configuration. The designation difference (CDBF versus CDBFR) reflects internal Comchip Technology product line categorization. Both are suitable substitutes for CDBF0230-HF.

Q: Why do CDBF0230L and CDBFR0230L specify reverse leakage current at 10V instead of 30V?

A: The measurement condition difference represents a specification variation within the product line. Both parts maintain the same 30µA maximum leakage rating; the difference is the voltage at which this parameter is characterized. This does not affect functional compatibility in circuits designed for the original CDBF0230-HF specifications.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts use identical surface mount packaging: 1005 (2512 Metric) with SOD-323F supplier device package designation. All are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Which substitute part offers the best supply availability?

A: CDBFR0230L provides the highest inventory level at 32400 pcs. This part is functionally equivalent to CDBF0230-HF with the noted reverse leakage measurement condition variance.

Q: Do all substitute parts meet the same compliance requirements as CDBF0230-HF?

A: Yes. All substitute parts are ROHS3 compliant, MSL Level 1 (Unlimited), REACH Unaffected, and share identical ECCN (EAR99) and HTSUS (8541.10.0070) classifications.
