Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT240AE6433HTMA1 is constrained by the following critical parameters:

Mandatory Matching Criteria:

• Diode Configuration: 1 Pair Series Connection
• Technology: Schottky
• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Moisture Sensitivity Level: 1 (Unlimited)

Voltage and Current Ratings: The BAT240AE6433HTMA1 operates at 240 V DC reverse voltage with 400 mA average rectified current per diode. Substitute parts must support these electrical specifications or higher ratings to ensure functional compatibility in the original application circuit.

Recovery Characteristics: Fast recovery speed (≤ 500 ns for Io > 200 mA) is a defining characteristic. Substitute parts must maintain equivalent or superior recovery performance.

The BAT6404E6327HTSA1 is listed as the manufacturer-recommended substitute. However, this part exhibits significantly lower voltage (40 V) and current (250 mA) ratings compared to the main part, indicating it is suitable only for applications with reduced electrical requirements or redesigned circuits operating at lower voltage and current levels.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The BAT240AE6433HTMA1 is classified as Obsolete. The BAT6404E6327HTSA1 is classified as Active with Automotive grade qualification and AEC-Q101 certification, indicating ongoing manufacturing support and suitability for automotive applications.

Compliance and Regulatory Status: Both parts are ROHS3 Compliant, REACH Unaffected, and carry ECCN EAR99 classification. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Electrical Rating Compatibility: Direct substitution of the BAT6404E6327HTSA1 for the BAT240AE6433HTMA1 is not supported based on electrical specifications. The substitute part operates at 40 V maximum reverse voltage and 250 mA average rectified current, representing a significant reduction from the original part's 240 V and 400 mA ratings. This substitute is applicable only in circuits redesigned to operate within the lower voltage and current envelope.

Package and Mounting Compatibility: Both parts share identical Surface Mount packaging (TO-236-3, SC-59, SOT-23-3) and supplier device package designation (PG-SOT23), ensuring mechanical and footprint compatibility on printed circuit boards.

Recovery Performance: Both parts maintain fast recovery characteristics (≤ 500 ns for Io > 200 mA). The BAT6404E6327HTSA1 specifies a reverse recovery time of 5 ns, indicating superior transient performance.

Frequently Asked Questions (FAQ)

Q: Can the BAT6404E6327HTSA1 be used as a direct replacement for the BAT240AE6433HTMA1 in existing circuits?

A: No. The BAT6404E6327HTSA1 has significantly lower voltage (40 V vs. 240 V) and current (250 mA vs. 400 mA) ratings. Direct substitution will result in component failure or circuit malfunction if the original application operates at or near the BAT240AE6433HTMA1 specifications. The substitute is suitable only for redesigned circuits operating within its lower electrical envelope.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both parts use the TO-236-3 (SC-59, SOT-23-3) Surface Mount package with PG-SOT23 supplier device package designation. PCB footprints are mechanically compatible.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) Diode Configuration (1 Pair Series Connection), (2) Technology (Schottky), (3) Voltage - DC Reverse rating, (4) Current - Average Rectified rating, (5) Recovery speed characteristics, (6) Mounting Type (Surface Mount), and (7) Package / Case (TO-236-3, SOT-23-3).

Q: Does the BAT6404E6327HTSA1 have automotive qualification?

A: Yes. The BAT6404E6327HTSA1 carries Automotive grade designation and AEC-Q101 qualification. The BAT240AE6433HTMA1 does not specify automotive qualification.

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

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures are sufficient.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
