Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDBHM220L-HF is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Technology: Schottky diode technology
• Voltage - Peak Reverse (Max): 20 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 550 mV @ 2 A
• Current - Reverse Leakage @ Vr: 1 mA @ 20 V
• Operating Temperature Range: -55°C to 125°C (TJ)
• Package / Case: TO-269AA, 4-BESOP (MBS-2)
• Mounting Type: Surface Mount

The CDBHM220L-G meets all these criteria and is identified as a parametric equivalent. The primary distinction between the main part and its substitute is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CDBHM220L-G is the direct parametric equivalent for the obsolete CDBHM220L-HF. Both components share identical electrical specifications, thermal operating range, and package configuration. The CDBHM220L-G maintains active product status, ensuring continued availability and supply chain support.

Both parts satisfy ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The primary operational difference is packaging format: the CDBHM220L-HF is supplied in bulk format, while the CDBHM220L-G is supplied in Tape & Reel (TR) format. This distinction affects handling, storage, and automated assembly processes but does not impact electrical or thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the CDBHM220L-G directly replace the CDBHM220L-HF in existing designs?

A: Yes. The CDBHM220L-G is a parametric equivalent with identical electrical ratings, thermal specifications, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between the CDBHM220L-HF and CDBHM220L-G?

A: The components are electrically and mechanically identical. The primary difference is product status (obsolete vs. active) and packaging format (bulk vs. Tape & Reel). The CDBHM220L-G is the recommended selection for new procurement due to active availability.

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

A: No. Both components are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent across both part numbers.

Q: Does the Tape & Reel packaging of the CDBHM220L-G affect electrical performance?

A: No. Packaging format does not affect electrical characteristics, thermal performance, or reliability. The difference is purely logistical, impacting handling and assembly processes.

Q: What is the moisture sensitivity level for these components?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
