Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDBV3-54C-G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

Acceptable Variation Parameters:

• Reverse Recovery Time (trr): 4 ns to 5 ns
• Operating Temperature - Junction: -65°C to 125°C (minimum -55°C acceptable)
• Packaging format: Tape & Reel (TR), Cut Tape (CT), or bulk

All identified substitutes meet these criteria. Differences in operating temperature range, packaging format, and reverse recovery time within specified tolerances do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Substitute (Preferred for Comchip Technology designs):

CDBV3-54C-HF is the active production equivalent from Comchip Technology. This part maintains identical electrical specifications with improved reverse recovery time (4 ns vs. 5 ns). It carries ROHS3 compliance and unlimited moisture sensitivity rating. Availability is confirmed at 1042 pieces in stock. Selection of this part eliminates manufacturer qualification changes while transitioning from obsolete to active product status.

Parametric Equivalents (Multi-source alternatives):

BAT54CW-7-F (Diodes Incorporated), BAT54CWQ-7-F (Diodes Incorporated), and BAT54CWT-TP (Micro Commercial Co) are parametrically equivalent alternatives. All three maintain the complete electrical specification set and SC-70, SOT-323 packaging. BAT54CWQ-7-F includes automotive-grade qualification (AEC-Q101) and extended operating temperature range (-65°C to 125°C), suitable for automotive and industrial applications. BAT54CW-7-F offers highest inventory availability (118,760 pieces) in Cut Tape format. BAT54CWT-TP provides Tape & Reel packaging with 3,390 pieces available.

BAT54CW RVG (Taiwan Semiconductor Corporation) is a parametric equivalent with active product status and bulk packaging availability (891 pieces in stock).

All substitute parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can CDBV3-54C-HF directly replace CDBV3-54C-G in existing designs?

A: Yes. CDBV3-54C-HF is the active production equivalent with identical electrical specifications, diode configuration, voltage ratings, current ratings, and package format. The improved reverse recovery time (4 ns vs. 5 ns) provides enhanced performance. Packaging format differs (Tape & Reel vs. bulk), which affects procurement and handling but not electrical compatibility.

Q: What is the difference between the Comchip substitute and the Diodes Incorporated substitutes?

A: CDBV3-54C-HF maintains the same manufacturer (Comchip Technology) as the original part, simplifying qualification and supply chain continuity. BAT54CW-7-F, BAT54CWQ-7-F, and BAT54CWT-TP are from different manufacturers (Diodes Incorporated, Micro Commercial Co) but meet identical electrical specifications. BAT54CWQ-7-F includes automotive qualification (AEC-Q101), making it suitable for automotive applications. All are parametrically equivalent for standard industrial applications.

Q: Are there operating temperature differences between substitutes?

A: The original CDBV3-54C-G and most substitutes specify maximum junction temperature of 125°C. BAT54CW-7-F and BAT54CWQ-7-F specify operating range of -65°C to 125°C, providing extended low-temperature performance. BAT54CWT-TP specifies -55°C to 125°C. These differences do not affect compatibility in standard temperature environments but provide additional margin in extreme cold applications.

Q: Does packaging format (Tape & Reel vs. Cut Tape vs. Bulk) affect electrical performance?

A: No. Packaging format affects procurement, handling, and automated assembly processes but does not alter electrical characteristics or functional performance. Selection should be based on manufacturing process requirements and inventory management practices.

Q: Is the improved reverse recovery time (4 ns) of CDBV3-54C-HF a requirement for substitution?

A: No. Reverse recovery time of 4 ns to 5 ns is within acceptable variation for this device category. The 4 ns specification of CDBV3-54C-HF represents improved performance but is not mandatory for functional equivalence. Applications sensitive to switching speed may benefit from the faster recovery time.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All identified substitutes carry ROHS3 compliance certification and unlimited moisture sensitivity rating (MSL 1), meeting current environmental and reliability standards.
