Substitute Part Grouping Explanation

Substitution eligibility for the CDBHM280L-HF is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Technology: Schottky
• Voltage - Peak Reverse (Max): 80 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 850 mV @ 2 A
• Current - Reverse Leakage @ Vr: 1 mA @ 80 V
• Operating Temperature Range: -55°C to 125°C (TJ)
• Package / Case: TO-269AA, 4-BESOP
• Mounting Type: Surface Mount

The substitute part identified maintains identical electrical specifications and mechanical compatibility, differing only in product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CDBHM280L-G is a direct functional equivalent to the CDBHM280L-HF. Both parts share identical electrical and mechanical specifications, including voltage ratings, current capacity, forward voltage characteristics, and temperature operating range. Both maintain ROHS3 compliance and MSL Level 1 rating.

The primary distinction is product status: the CDBHM280L-HF is obsolete, while the CDBHM280L-G is active. For new designs, ongoing production, and long-term availability, the CDBHM280L-G is the appropriate selection. The packaging difference (Tape & Reel versus bulk) reflects standard industry practice for active components and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can CDBHM280L-G replace CDBHM280L-HF in existing designs?

A: Yes. The CDBHM280L-G is electrically and mechanically identical to the CDBHM280L-HF across all specified parameters. Direct substitution is valid for applications currently using the CDBHM280L-HF.

Q: What is the difference between the two part numbers?

A: The CDBHM280L-HF and CDBHM280L-G differ in product status and packaging format. The CDBHM280L-HF is obsolete and supplied in bulk packaging. The CDBHM280L-G is active and supplied in Tape & Reel format. Electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?
