Substitute Part Grouping Explanation

Substitution eligibility for the BAS16E6393HTSA1 is determined by the following critical parameters:

Mandatory Matching Criteria:

Package / Case: TO-236-3, SC-59, SOT-23-3 (surface mount compatibility)
Mounting Type: Surface Mount
Voltage - DC Reverse (Vr) (Max): Must equal or exceed 80 V
Current - Average Rectified (Io): Must equal or exceed 250 mA
Voltage - Forward (Vf) (Max) @ If: Must not exceed 1.25 V @ 150 mA
Operating Temperature - Junction (Max): Must support 150°C minimum

Preferred Alignment:

Grade: Automotive
Qualification: AEC-Q101
RoHS Status: ROHS3 Compliant
Technology: Standard

Substitute parts are grouped into two categories based on electrical performance alignment:

Category A - Full Parameter Match (Infineon BAS16 Series): Parts BAS16E6327HTSA1 and BAS16E6433HTMA1 maintain identical electrical specifications to the main part across all critical parameters. These are direct parametric equivalents differing only in packaging format (Cut Tape vs. Tape & Reel).

Category B - Functional Equivalents with Parameter Variance (onsemi Alternatives): Parts BAS16LT1G, SBAS16LT1G, and BAS116LT1G provide functional substitution with specified parameter deviations. These parts maintain SOT-23-3 package compatibility and automotive qualification but exhibit differences in current rating, voltage rating, or recovery time characteristics.

Engineering Selection Recommendations

For Direct Replacement (Infineon BAS16 Series):

BAS16E6327HTSA1 and BAS16E6433HTMA1 are parametric equivalents to the BAS16E6393HTSA1. Both maintain identical electrical specifications across voltage, current, forward voltage, and recovery time parameters. Selection between these two should be based on packaging requirements: BAS16E6327HTSA1 is supplied in Cut Tape format, while BAS16E6433HTMA1 is supplied in Tape & Reel format. Both are Last Time Buy status parts with ROHS3 compliance.

For Active Production Alternatives (onsemi BAS16 / SBAS16 Series):

BAS16LT1G and SBAS16LT1G are active production parts from onsemi, both rated for 100 V reverse voltage and 200 mA average rectified current. SBAS16LT1G carries automotive grade designation and AEC-Q101 qualification, matching the original part's compliance profile. BAS16LT1G is available in higher volume (665,100 pcs) and provides the same electrical performance as SBAS16LT1G with active product status. Both exhibit 6 ns reverse recovery time compared to the original 4 ns specification.

For Lower Voltage Applications:

BAS116LT1G is rated for 75 V reverse voltage and 200 mA average rectified current. This part is suitable only for applications where the 80 V reverse voltage specification of the original part can be reduced to 75 V without circuit impact. BAS116LT1G exhibits significantly longer reverse recovery time (3 µs) and lower reverse leakage current (5 nA @ 75 V), making it unsuitable for high-speed switching applications requiring the fast recovery characteristics of the original part.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and SOT-23-3 package compatibility. SBAS16LT1G and the original BAS16E6393HTSA1 both carry AEC-Q101 automotive qualification. For automotive applications requiring AEC-Q101 certification, SBAS16LT1G is the preferred active production alternative.

Frequently Asked Questions (FAQ)

Q: Can BAS16LT1G directly replace BAS16E6393HTSA1 in all applications?

A: BAS16LT1G provides functional substitution with specified parameter differences. The part is rated for 100 V reverse voltage (exceeding the original 80 V specification) and maintains identical forward voltage characteristics. However, BAS16LT1G is classified as Small Signal with 6 ns recovery time, compared to the original Fast Recovery classification with 4 ns recovery time. Applications requiring fast recovery switching performance below 6 ns may not be suitable for this substitute. Verify circuit timing requirements before selection.

Q: What is the difference between BAS16E6327HTSA1 and BAS16E6433HTMA1?

A: Both parts are parametric equivalents with identical electrical specifications. The difference is packaging format only: BAS16E6327HTSA1 is supplied in Cut Tape (CT) format, while BAS16E6433HTMA1 is supplied in Tape & Reel (TR) format. Selection depends on assembly line equipment compatibility and volume requirements.

Q: Is SBAS16LT1G suitable for automotive applications?

A: Yes. SBAS16LT1G carries automotive grade designation and AEC-Q101 qualification, matching the original part's compliance requirements. It is rated for 100 V reverse voltage and 200 mA average rectified current with 6 ns reverse recovery time. This part is an active production component from onsemi with high inventory availability.

Q: Why does BAS116LT1G have lower reverse leakage current than the original part?

A: BAS116LT1G is specified with 5 nanoamperes reverse leakage at 75 V, compared to 1 microampere at 75 V for the original part. This difference reflects different semiconductor process technology and device design between manufacturers. The lower leakage characteristic of BAS116LT1G may provide benefits in low-power applications but does not affect high-current switching performance.

Q: Can I use BAS116LT1G in a circuit designed for 80 V reverse voltage?

A: BAS116LT1G is rated for maximum 75 V reverse voltage. Using this part in a circuit specified for 80 V reverse voltage exceeds the device rating and creates reliability risk. This substitution is only acceptable if circuit analysis confirms that reverse voltage stress will not exceed 75 V under all operating conditions, including transient overvoltage events.

Q: What is the significance of "Last Time Buy" status for the original part?

A: Last Time Buy status indicates that Infineon has ceased new production of BAS16E6393HTSA1. Existing inventory will be depleted without replenishment. For long-term supply continuity, designs should transition to active production alternatives such as BAS16LT1G or SBAS16LT1G from onsemi.

Q: Are all substitute parts available in the same SOT-23-3 package?

A: Yes. All substitute parts listed are supplied in TO-236-3 / SC-59 / SOT-23-3 surface mount package format, ensuring mechanical and electrical compatibility with the original part's PCB footprint and assembly process.
