Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BAT54AWQ-7-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Common Anode
• 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):

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

Compliance Parameters (Considered for Selection):

• RoHS Status
• Moisture Sensitivity Level (MSL)
• Product Status (Active vs. Discontinued)
• Automotive Grade and AEC-Q101 Qualification

All identified substitute parts maintain identical electrical and mechanical specifications. Variations in operating temperature range, manufacturer, and compliance certifications are noted for engineering selection purposes.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BAT54AW-7-F

The BAT54AW-7-F is the preferred substitute for the BAT54AWQ-7-F. Both parts are manufactured by Diodes Incorporated and maintain identical electrical and mechanical specifications. The BAT54AW-7-F is Active in product status with significantly higher inventory availability (35,100 pieces). Both parts are ROHS3 compliant with MSL 1 rating. The primary distinction is that BAT54AW-7-F does not carry automotive grade or AEC-Q101 qualification. Selection of BAT54AW-7-F is appropriate for non-automotive applications or where automotive qualification is not a design requirement.

Secondary Substitute: BAT54AWQ-13-F

The BAT54AWQ-13-F is an equivalent alternative manufactured by Diodes Incorporated with identical electrical and mechanical specifications. This part maintains Active product status, ROHS3 compliance, and automotive grade with AEC-Q101 qualification, matching the compliance profile of the main part. Inventory availability is lower (871 pieces). BAT54AWQ-13-F is suitable for automotive applications requiring AEC-Q101 qualification.

Alternative Substitute: BAT54AWT-TP

The BAT54AWT-TP is manufactured by Micro Commercial Co and maintains identical electrical and mechanical specifications with one exception: the operating temperature range is -55°C ~ 125°C compared to -65°C ~ 125°C for the main part. This part is Active in product status, ROHS3 compliant, and has the highest inventory availability (42,679 pieces). BAT54AWT-TP is suitable for applications where the lower temperature limit of -55°C is acceptable.

Not Recommended: BAT54AW-7

The BAT54AW-7 is discontinued at DiGi Electronics and is RoHS non-compliant. While electrically and mechanically equivalent, this part should not be selected for new designs or applications requiring RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can BAT54AW-7-F be used as a direct replacement for BAT54AWQ-7-F?

A: Yes. The BAT54AW-7-F is electrically and mechanically equivalent to the BAT54AWQ-7-F. Both parts share identical specifications for diode configuration, voltage ratings, current ratings, forward voltage, reverse recovery time, and reverse leakage current. Both are housed in SC-70, SOT-323 packages and are ROHS3 compliant. The primary difference is that BAT54AW-7-F does not carry automotive grade or AEC-Q101 qualification. For non-automotive applications, BAT54AW-7-F is a direct substitute.

Q: What is the difference between BAT54AWQ-7-F and BAT54AWQ-13-F?

A: Both parts are manufactured by Diodes Incorporated and are electrically and mechanically identical. Both carry automotive grade and AEC-Q101 qualification. The designation difference (AWQ-7-F vs. AWQ-13-F) reflects different manufacturing batches or date codes. Both are suitable for automotive applications requiring AEC-Q101 qualification.

Q: Can BAT54AWT-TP replace BAT54AWQ-7-F in all applications?

A: BAT54AWT-TP is electrically and mechanically equivalent with one specification difference: the operating temperature range is -55°C ~ 125°C versus -65°C ~ 125°C for the main part. BAT54AWT-TP is suitable for applications where the lower temperature limit of -55°C is acceptable. For applications requiring operation below -55°C, the main part or BAT54AW-7-F should be used.

Q: Why is BAT54AW-7 not recommended as a substitute?

A: BAT54AW-7 is discontinued at DiGi Electronics and is RoHS non-compliant. While electrically and mechanically equivalent, this part does not meet current compliance requirements and has limited availability. BAT54AW-7-F should be selected instead for equivalent functionality with active product status and ROHS3 compliance.

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

A: Yes. All substitute parts identified are housed in SC-70, SOT-323 surface mount packages with identical pin configurations and mechanical dimensions. All parts are supplied in Tape & Reel (TR) packaging format.

Q: What is the significance of the automotive grade and AEC-Q101 qualification?

A: Automotive grade and AEC-Q101 qualification indicate that the part meets stringent reliability and quality standards established by the Automotive Electronics Council. These certifications are required for components used in automotive applications. BAT54AWQ-7-F and BAT54AWQ-13-F carry these qualifications. BAT54AW-7-F and BAT54AWT-TP do not carry automotive qualifications and should not be used in automotive designs requiring these certifications.

Q: Which substitute part has the best inventory availability?

A: BAT54AWT-TP has the highest inventory availability with 42,679 pieces in stock. BAT54AW-7-F has 35,100 pieces available. For applications where inventory availability is a critical factor and the -55°C lower temperature limit is acceptable, BAT54AWT-TP is the preferred choice.
