BAT54WT-TP Equivalent & Substitute Parts

Part Overview

The BAT54WT-TP is a Schottky diode manufactured by Micro Commercial Co, rated for 30V DC reverse voltage and 200mA average rectified current in a surface mount SOT-323 package. This component is classified as a small signal Schottky rectifier diode with a 5 nanosecond reverse recovery time, suitable for high-speed switching applications. The part is currently Active in product status with RoHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical package compatibility, and regulatory compliance standards. Substitution becomes necessary when the primary part experiences supply constraints, discontinuation, or when design requirements permit selection from qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT54WT-TP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 30V
• Current - Average Rectified (Io): 200mA
• Voltage - Forward (Vf) (Max) @ If: 1V @ 100mA
• Reverse Recovery Time (trr): 5ns
• Current - Reverse Leakage @ Vr: 2µA @ 25V
• Capacitance @ Vr, F: 10pF
• Package / Case: SC-70, SOT-323
• Technology: Schottky
• Mounting Type: Surface Mount

Acceptable Variations:

• Operating Temperature - Junction range may extend beyond the primary part specification
• Packaging format (Tape & Reel vs. Cut Tape) does not affect electrical equivalence
• Capacitance measurement frequency reference point (0V vs. 1V) does not affect functional substitution

The substitute parts identified below maintain full electrical and mechanical compatibility with the BAT54WT-TP within the specified parameter tolerances.

Engineering Selection Recommendations

Primary Equivalent: BAT54W-7-F (Diodes Incorporated)

The BAT54W-7-F is the preferred substitute for the BAT54WT-TP. Both parts are Active in product status, RoHS3 compliant, and available in Tape & Reel packaging. The BAT54W-7-F maintains identical electrical specifications across all critical parameters and offers extended operating temperature range (-65°C to 125°C versus -55°C to 125°C). Current inventory of 23,200 units supports production requirements.

Secondary Equivalent: BAT54WQ-7-F (Diodes Incorporated)

The BAT54WQ-7-F is an automotive-grade substitute qualified to AEC-Q101 standard. This part is suitable for applications requiring automotive qualification and meets all electrical specifications of the BAT54WT-TP. The BAT54WQ-7-F is Active in product status, RoHS3 compliant, and available in Tape & Reel packaging with the highest current inventory of 98,300 units.

Not Recommended: BAT54W-7 (Diodes Incorporated)

The BAT54W-7 is discontinued at DiGi Electronics and carries RoHS non-compliance status. Although electrical specifications match the primary part, the discontinued product status and regulatory non-compliance make this option unsuitable for new designs or ongoing production.

Frequently Asked Questions (FAQ)

Q: Can BAT54W-7-F be used as a direct replacement for BAT54WT-TP in existing designs?

A: Yes. The BAT54W-7-F maintains identical electrical specifications for voltage rating, current capacity, forward voltage drop, reverse recovery time, reverse leakage current, and capacitance. Both parts use the SC-70 SOT-323 surface mount package with identical pinout and footprint compatibility.

Q: What is the difference between BAT54W-7-F and BAT54WQ-7-F?

A: The BAT54WQ-7-F is automotive-grade and qualified to AEC-Q101 standard, making it suitable for automotive applications. The BAT54W-7-F is a standard industrial-grade part. Both maintain identical electrical specifications and package compatibility. Selection depends on application requirements for automotive qualification.

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

A: No. Packaging format affects only handling, storage, and assembly logistics. The electrical and mechanical specifications of the diode remain unchanged regardless of whether the part is supplied in Tape & Reel or Cut Tape format.

Q: Why is BAT54W-7 not recommended as a substitute?

A: The BAT54W-7 is discontinued at DiGi Electronics and does not comply with RoHS3 standards. While electrical specifications match the primary part, the discontinued status and regulatory non-compliance make this option unsuitable for new designs or ongoing production support.

Q: Are there temperature range differences between the primary part and substitutes?

A: Yes. The BAT54WT-TP operates from -55°C to 125°C junction temperature, while BAT54W-7-F and BAT54WQ-7-F operate from -65°C to 125°C. The extended lower temperature range of the substitutes provides additional design margin and does not restrict their use in applications designed for the primary part.

Q: What compliance standards apply to these parts?

A: All recommended substitutes (BAT54W-7-F and BAT54WQ-7-F) are RoHS3 compliant and REACH unaffected. Both carry ECCN classification EAR99 and HTSUS code 8541.10.0070. The BAT54WQ-7-F additionally carries AEC-Q101 automotive qualification.

Q: Is the BAT54WT-TP still in active production?

A: Yes. The BAT54WT-TP is Active in product status with 4,300 units currently in stock. However, the recommended substitutes BAT54W-7-F and BAT54WQ-7-F offer higher inventory availability (23,200 and 98,300 units respectively) and may provide better supply chain continuity.
