Substitution of the BAT54CW-7-F-79 is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V

Mechanical Parameters (Must Match):

• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

Environmental & Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant

Substitute parts identified below maintain identical electrical and mechanical specifications. Variations in product status, packaging format (Cut Tape, Tape & Reel), manufacturer, and operating temperature range do not affect functional equivalence when all critical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BAT54CW-7-F (Diodes Incorporated)

The BAT54CW-7-F is the direct parametric equivalent to the BAT54CW-7-F-79. Both components are manufactured by Diodes Incorporated and maintain identical electrical and mechanical specifications. The BAT54CW-7-F carries Active product status with significantly higher inventory availability (118,760 units). This part is supplied in Cut Tape and Digi-Reel packaging formats, suitable for both manual and automated assembly processes. Selection of BAT54CW-7-F is recommended as the primary replacement for obsolete BAT54CW-7-F-79 applications.

Secondary Substitute: BAT54CWQ-7-F (Diodes Incorporated)

The BAT54CWQ-7-F maintains full parametric equivalence and is manufactured by Diodes Incorporated with Active product status. This variant includes AEC-Q101 automotive qualification and Automotive grade designation, making it suitable for applications requiring automotive-level reliability. The part is supplied in Tape & Reel packaging with 3,300 units in stock. Selection of BAT54CWQ-7-F is appropriate for automotive and mission-critical applications.

Tertiary Substitute: BAT54CWT-TP (Micro Commercial Co)

The BAT54CWT-TP is manufactured by Micro Commercial Co and maintains full parametric equivalence across all critical electrical and mechanical parameters. This part carries Active product status with 3,390 units in stock and is supplied in Tape & Reel packaging. Operating temperature range is -55°C to 125°C, which is narrower than the main part but remains suitable for standard industrial applications.

Alternative Substitute: BAT54CW RVG (Taiwan Semiconductor Corporation)

The BAT54CW RVG is manufactured by Taiwan Semiconductor Corporation and maintains parametric equivalence across all critical electrical and mechanical specifications. This part carries Active product status with 891 units in stock. Operating temperature specification lists -125°C maximum, which differs from the standard range format but does not affect functional equivalence for applications within the -65°C to 125°C operating window.

All identified substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can BAT54CW-7-F be used as a direct replacement for BAT54CW-7-F-79?

A: Yes. The BAT54CW-7-F is a direct parametric equivalent. Both components share identical electrical specifications (30 V reverse voltage, 200 mA current rating, 1 V forward voltage at 100 mA, 5 ns reverse recovery time), mechanical configuration (1 Pair Common Cathode, SC-70 SOT-323 package), and compliance status (ROHS3, MSL 1). The primary difference is product status: BAT54CW-7-F-79 is Obsolete while BAT54CW-7-F is Active with higher inventory availability.

Q: What is the difference between BAT54CW-7-F and BAT54CWQ-7-F?

A: Both parts are manufactured by Diodes Incorporated and maintain identical electrical and mechanical specifications. The BAT54CWQ-7-F includes AEC-Q101 automotive qualification and Automotive grade designation, making it suitable for automotive applications requiring enhanced reliability standards. The BAT54CW-7-F is the standard industrial variant. Selection depends on application requirements for automotive qualification.

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

A: No. Packaging formats vary among substitutes. BAT54CW-7-F is supplied in Cut Tape and Digi-Reel formats. BAT54CWQ-7-F and BAT54CWT-TP are supplied in Tape & Reel format. BAT54CW RVG packaging format is not specified. Verify packaging compatibility with your assembly process requirements before selection.

Q: Do operating temperature ranges affect substitution compatibility?

A: Operating temperature ranges vary among substitutes but do not affect functional equivalence when applications operate within the overlapping temperature window. BAT54CW-7-F and BAT54CWQ-7-F specify -65°C to 125°C. BAT54CWT-TP specifies -55°C to 125°C. BAT54CW RVG specifies -125°C maximum. For applications operating within -55°C to 125°C, all substitutes are compatible. For applications requiring -65°C operation, select BAT54CW-7-F or BAT54CWQ-7-F.

Q: Which substitute has the best inventory availability?

A: BAT54CW-7-F has the highest inventory availability with 118,760 units in stock, compared to 3,390 units for BAT54CWT-TP, 3,300 units for BAT54CWQ-7-F, and 891 units for BAT54CW RVG. For applications requiring immediate availability and high-volume procurement, BAT54CW-7-F is the recommended selection.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All identified substitute parts (BAT54CW-7-F, BAT54CWQ-7-F, BAT54CWT-TP, and BAT54CW RVG) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the main part BAT54CW-7-F-79.

Q: Can BAT54CW RVG from Taiwan Semiconductor Corporation be used interchangeably with Diodes Incorporated variants?

A: Yes. BAT54CW RVG maintains identical electrical specifications (30 V reverse voltage, 200 mA current, 1 V forward voltage, 5 ns reverse recovery time) and mechanical configuration (1 Pair Common Cathode, SC-70 SOT-323 package). Manufacturer differences do not affect functional equivalence when all critical parameters align. Selection may depend on supply chain preferences and inventory availability.

Q: What is the significance of the "1 Pair Common Cathode" configuration?

A: The 1 Pair Common Cathode configuration indicates the diode array contains two Schottky diodes with a shared cathode connection. This configuration is essential for specific circuit topologies and cannot be substituted with alternative configurations such as 1 Pair Common Anode or isolated diode pairs. All identified substitutes maintain this identical configuration.
