Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAS16UE6327HTSA1 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Configuration: 3 Independent (must match exactly)
• Current Rating: 200 mA (DC) per diode (must match or exceed)
• Package / Case: SC-74, SOT-457 (must match exactly for PCB compatibility)
• Mounting Type: Surface Mount (must match)
• Technology: Standard (must match)

Allowable Substitution Parameters:

• Voltage - DC Reverse (Vr): Substitute parts may have equal or higher voltage ratings. The BAS16UE6327HTSA1 operates at 80 V maximum; substitute parts rated at 250 V are electrically compatible and provide enhanced voltage margin.
• Forward Voltage (Vf): Minor variations within the small signal diode classification are acceptable.
• Reverse Recovery Time (trr): Variations are acceptable within the small signal speed classification.
• Reverse Leakage Current: Variations are acceptable.
• Operating Temperature Range: Substitute parts may have extended temperature ranges.
• Product Status: Active products are preferred over obsolete products for new designs and ongoing supply.

The substitute parts BAS21TMR6T1G and NSVBAS21TMR6T1G meet all mandatory compatibility criteria and provide higher voltage ratings with active product status.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: The NSVBAS21TMR6T1G is the primary recommended substitute. This part maintains full functional compatibility with the BAS16UE6327HTSA1 while offering active product status, higher voltage rating (250 V), extended operating temperature range (-55°C to 150°C), and superior reverse leakage characteristics (100 nA @ 200 V). The part is ROHS3 compliant and carries unlimited moisture sensitivity rating. Inventory availability is substantial (263,200 pcs).

Alternative Selection: The BAS21TMR6T1G is an equivalent alternative from onsemi with identical electrical specifications to the NSVBAS21TMR6T1G. This part includes AEC-Q101 automotive qualification, which may be required for automotive applications. Inventory availability is adequate (15,100 pcs).

Compatibility Assurance: Both substitute parts are pin-compatible and functionally equivalent within the SC-74 (SOT-457) package footprint. The higher voltage rating (250 V vs. 80 V) of the substitute parts provides additional design margin and does not compromise performance in applications designed for the original 80 V specification. All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the BAS21TMR6T1G or NSVBAS21TMR6T1G be used as direct replacements for the BAS16UE6327HTSA1 on existing PCBs?

A: Yes. Both substitute parts are pin-compatible and functionally equivalent. The SC-74 (SOT-457) package footprint is identical, and the 3-independent diode configuration matches exactly. No PCB layout modifications are required.

Q: Why do the substitute parts have a higher voltage rating (250 V vs. 80 V)?

A: Higher voltage ratings in substitute parts provide enhanced design margin and do not affect performance in applications designed for lower voltages. The substitute parts remain fully compatible with circuits designed for 80 V operation. The higher rating ensures broader application compatibility.

Q: What is the difference between BAS21TMR6T1G and NSVBAS21TMR6T1G?

A: Both parts are functionally equivalent with identical electrical specifications. The primary differences are: BAS21TMR6T1G includes AEC-Q101 automotive qualification and carries a base product number of BAS21. NSVBAS21TMR6T1G carries a base product number of NSVBAS21 and has superior reverse leakage characteristics (100 nA @ 200 V vs. 1 µA @ 200 V). Select BAS21TMR6T1G for automotive applications requiring AEC-Q101 qualification; select NSVBAS21TMR6T1G for general-purpose applications requiring lower leakage current.

Q: Are the substitute parts ROHS3 compliant?

A: Yes. Both BAS21TMR6T1G and NSVBAS21TMR6T1G are ROHS3 compliant, matching the compliance status of the original BAS16UE6327HTSA1.

Q: What is the moisture sensitivity level (MSL) of the substitute parts?

A: Both substitute parts carry MSL 1 (Unlimited), identical to the original part. No special moisture control measures are required during storage or handling.

Q: Why is the BAS16UE6327HTSA1 classified as obsolete?

A: The BAS16UE6327HTSA1 has reached end-of-life status with Infineon Technologies. The substitute parts from onsemi provide equivalent functionality with active product status, ensuring long-term supply chain availability and support.

Q: Can I use these substitute parts in high-temperature applications?

A: Yes. The substitute parts support operating junction temperatures up to 150°C (maximum), matching the original part. Additionally, the substitute parts offer an extended operating temperature range of -55°C to 150°C, providing broader temperature margin for demanding applications.

Q: What is the reverse recovery time difference, and does it affect circuit performance?

A: The original BAS16UE6327HTSA1 has a reverse recovery time (trr) of 4 ns, while the substitute parts have 50 ns. Both values fall within the small signal diode classification (≤ 200 mA, Any Speed). The difference does not affect performance in general-purpose rectification applications. For high-frequency switching applications, verify that 50 ns recovery time meets circuit timing requirements.
