Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAT74,235 are classified into two categories based on substitution criteria:

Parametric Equivalent (Direct Substitute): Parts that maintain identical electrical specifications and the same package format. These substitutes satisfy all functional requirements without design modification.

Similar Substitute (Package Variant): Parts that maintain identical electrical specifications but utilize a different surface mount package. These substitutes require PCB layout modification and are selected when the original package is unavailable.

Substitution eligibility is determined by the following parameters:

• Diode Configuration: 2 Independent
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io) (per Diode): 200 mA (DC)
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 2 µA @ 25 V
• Operating Temperature - Junction (Max): 125°C
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Engineering Selection Recommendations

BAT74,215 (Parametric Equivalent - Nexperia USA Inc.)

The BAT74,215 is a direct parametric equivalent to the BAT74,235. Both parts are manufactured by Nexperia USA Inc., share identical electrical specifications, and utilize the same SOT-143B package. The primary distinction is packaging format: BAT74,215 is supplied in Cut Tape (CT) & Digi-Reel® format, while BAT74,235 is supplied in Tape & Reel (TR) format. Both parts maintain Active product status, AEC-Q100 automotive qualification, and ROHS3 compliance. The BAT74,215 offers higher inventory availability at 49,747 units. Selection of this part requires no design modification and is suitable for direct substitution in applications where packaging format compatibility exists.

MBD54DWT1G (Similar Substitute - onsemi)

The MBD54DWT1G is a similar substitute manufactured by onsemi that maintains identical electrical performance across all critical parameters: 30 V reverse voltage, 200 mA average rectified current, 5 ns reverse recovery time, and 2 µA reverse leakage current. The forward voltage specification differs at 1 V @ 100 mA compared to 800 mV @ 100 mA for the BAT74,235, representing a 200 mV maximum increase. The MBD54DWT1G utilizes a 6-TSSOP (SC-88/SOT-363) package, which differs from the SOT-143B package of the main part. This substitution requires PCB layout modification to accommodate the different package footprint and pin configuration. The part maintains Active product status, ROHS3 compliance, and MSL 1 rating. Selection of this part is appropriate when the original package is unavailable and PCB redesign is feasible.

Frequently Asked Questions (FAQ)

Q: Can BAT74,215 be used as a direct replacement for BAT74,235?

A: Yes. The BAT74,215 is a parametric equivalent with identical electrical specifications and package type (SOT-143B). The difference in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) does not affect electrical performance or PCB assembly compatibility. No design modification is required.

Q: What is the primary difference between BAT74,235 and MBD54DWT1G?

A: The primary difference is the package format. BAT74,235 uses SOT-143B (TO-253-4), while MBD54DWT1G uses SC-88/SOT-363 (6-TSSOP). Additionally, the forward voltage specification for MBD54DWT1G is 1 V @ 100 mA compared to 800 mV @ 100 mA for BAT74,235. PCB layout modification is required for MBD54DWT1G substitution.

Q: Are all substitute parts AEC-Q100 qualified?

A: BAT74,215 carries AEC-Q100 automotive qualification identical to BAT74,235. MBD54DWT1G does not list AEC-Q100 qualification in the provided specifications. Verification of automotive qualification requirements for the application is necessary when selecting MBD54DWT1G.

Q: What is the impact of the forward voltage difference in MBD54DWT1G?

A: The MBD54DWT1G forward voltage specification is 1 V @ 100 mA, compared to 800 mV @ 100 mA for BAT74,235. This 200 mV maximum difference affects power dissipation and voltage drop characteristics in the circuit. Circuit analysis is required to determine if this difference is acceptable for the specific application.

Q: Can MBD54DWT1G be used without PCB modification?

A: No. MBD54DWT1G uses a 6-TSSOP (SC-88) package with different pin configuration and footprint compared to the SOT-143B package of BAT74,235. PCB layout modification is required for this substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. BAT74,215 and MBD54DWT1G are both ROHS3 compliant, matching the compliance status of BAT74,235.

Q: What is the moisture sensitivity level for all parts?

A: All three parts (BAT74,235, BAT74,215, and MBD54DWT1G) have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
