Substitute Part Grouping Explanation

Substitution of the BAT54SW RVG is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Diode Configuration: 1 Pair Series Connection
• 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
• Package / Case: SC-70, SOT-323
• Mounting Type: Surface Mount

All identified substitute parts meet these electrical and mechanical specifications. Variations in operating temperature range, packaging format (Tape & Reel versus bulk), and automotive qualification do not affect functional equivalence in standard applications. The BAT54SW-7-F, BAT54SWQ-7-F, and BAT54SWT-TP are direct parametric equivalents manufactured by Diodes Incorporated and Micro Commercial Co respectively.

Parameter Comparison

Engineering Selection Recommendations

BAT54SW-7-F (Diodes Incorporated): This substitute provides full parametric equivalence with extended operating temperature range (-65°C to 125°C) compared to the BAT54SW RVG. The component is available in Tape & Reel packaging format and maintains ROHS3 compliance and MSL 1 rating. Selection is appropriate for applications requiring higher inventory availability (65,400 pcs in stock) and standard commercial environments.

BAT54SWQ-7-F (Diodes Incorporated): This substitute is identical in electrical specifications to the BAT54SW-7-F but includes AEC-Q101 automotive qualification. The operating temperature range is -65°C to 125°C. This variant is specified for automotive applications requiring formal qualification documentation. Inventory availability is 3,000 pcs.

BAT54SWT-TP (Micro Commercial Co): This substitute provides full parametric equivalence with operating temperature range of -55°C to 125°C. The component is available in Tape & Reel packaging and maintains ROHS3 compliance and MSL 1 rating. Inventory availability is 46,388 pcs. Selection is appropriate for applications with standard commercial temperature requirements and high-volume procurement needs.

All three substitutes are active products with ROHS3 compliance, REACH unaffected status, and identical electrical performance within the specified parameters. Selection among substitutes is based on packaging format preference, temperature range requirements, automotive qualification necessity, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can BAT54SW-7-F be used as a direct replacement for BAT54SW RVG?

A: Yes. The BAT54SW-7-F is a parametric equivalent with identical electrical specifications including 30 V reverse voltage, 200 mA average rectified current, 1 V forward voltage at 100 mA, and 5 ns reverse recovery time. Both components use SC-70, SOT-323 surface mount packaging. The primary difference is packaging format (Tape & Reel versus bulk) and extended operating temperature range (-65°C to 125°C versus standard commercial range).

Q: What is the difference between BAT54SW-7-F and BAT54SWQ-7-F?

A: Both parts are electrically identical with 30 V reverse voltage and 200 mA current rating. The BAT54SWQ-7-F includes AEC-Q101 automotive qualification and is specified for automotive applications. The BAT54SW-7-F is a standard commercial grade equivalent. Operating temperature ranges are identical at -65°C to 125°C.

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

A: No. The BAT54SW RVG is supplied in bulk packaging. The BAT54SW-7-F, BAT54SWQ-7-F, and BAT54SWT-TP are all supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not impact electrical performance or mechanical compatibility in the SC-70, SOT-323 package.

Q: Which substitute should be selected for automotive applications?

A: The BAT54SWQ-7-F is specified for automotive applications with AEC-Q101 qualification. This variant is required when formal automotive qualification documentation is necessary. All other substitutes are standard commercial grade.

Q: Do all substitutes meet RoHS and MSL requirements?

A: Yes. All substitute parts (BAT54SW-7-F, BAT54SWQ-7-F, and BAT54SWT-TP) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the BAT54SW RVG specifications.

Q: What is the operating temperature range difference between substitutes?

A: The BAT54SW-7-F and BAT54SWQ-7-F operate from -65°C to 125°C. The BAT54SWT-TP operates from -55°C to 125°C. The BAT54SW RVG operates to a maximum junction temperature of 125°C. Selection depends on application temperature requirements.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts use identical SC-70, SOT-323 surface mount packaging with the same pin configuration and footprint. They are mechanically and electrically interchangeable in circuit designs specified for the BAT54SW RVG.
