Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BAS19-7-G are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 200 mA
• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount
• Speed Classification: Small Signal ≤ 200mA (Io), Any Speed
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts listed maintain these core parameters, ensuring functional equivalence in circuit applications. Variations in forward voltage (Vf), reverse recovery time (trr), reverse leakage current, and capacitance represent performance differences within acceptable operating ranges for general-purpose rectification applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: BAS19-7-F

BAS19-7-F is the direct Diodes Incorporated equivalent with active product status. This part maintains identical electrical specifications to the obsolete BAS19-7-G and offers the widest operating temperature range (-65°C to 150°C). Selection of BAS19-7-F provides continuity with the original design intent and manufacturer support.

Alternative Substitutes:

BAS19-G3-18 (Vishay General Semiconductor - Diodes Division) provides equivalent electrical performance with active status. Operating temperature range is -55°C to 150°C, which is suitable for most applications requiring the original BAS19-7-G.

MMBD1201 (onsemi) offers improved performance characteristics including lower forward voltage (1 V @ 200 mA) and faster reverse recovery time (4 ns). This part is suitable for applications where reduced power dissipation and switching speed are beneficial.

MMBD914LT3G (onsemi) provides fast switching performance (4 ns reverse recovery time) with active product status and extensive inventory availability. This part is appropriate for high-frequency switching applications.

SBAS16LT1G (onsemi) is qualified to AEC-Q101 automotive standards and provides active product status. This part is required for automotive applications or designs requiring automotive-grade component certification.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original BAS19-7-G specification.

Frequently Asked Questions (FAQ)

Q: Can BAS19-7-F be used as a direct replacement for BAS19-7-G?

A: Yes. BAS19-7-F is manufactured by Diodes Incorporated and maintains identical electrical specifications (100 V reverse voltage, 200 mA average rectified current, SOT-23-3 package). BAS19-7-F has active product status and is the recommended direct substitute.

Q: What is the difference between BAS19-7-F and MMBD1201?

A: Both parts meet the core electrical requirements (100 V, 200 mA, SOT-23-3). MMBD1201 offers lower forward voltage (1 V @ 200 mA versus 1.25 V) and faster reverse recovery time (4 ns versus 50 ns). MMBD1201 is manufactured by onsemi. Selection depends on application requirements for power dissipation and switching speed.

Q: Is SBAS16LT1G suitable for non-automotive applications?

A: Yes. SBAS16LT1G meets all electrical and mechanical requirements for general-purpose rectification. The AEC-Q101 automotive qualification is an additional certification that does not restrict use in non-automotive applications. This part is suitable for any application requiring the BAS19-7-G electrical specifications.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts are packaged in SOT-23-3 (TO-236-3, SC-59) surface mount configuration, maintaining mechanical compatibility with the original BAS19-7-G PCB layout and assembly process.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. All listed substitute parts carry MSL 1 rating, ensuring no additional moisture handling or baking procedures are required during storage or assembly.

Q: Can MMBD914LT3G replace BAS19-7-G in all applications?

A: MMBD914LT3G meets the core electrical specifications (100 V, 200 mA, SOT-23-3). The faster reverse recovery time (4 ns versus 50 ns for BAS19-7-F) may affect circuit behavior in timing-sensitive applications. Verification of circuit performance is necessary when switching from standard-speed to fast-recovery diodes.

Q: What is the difference between BAS19-G3-18 and BAS19-7-F?

A: Both parts meet identical electrical specifications. BAS19-G3-18 is manufactured by Vishay, while BAS19-7-F is manufactured by Diodes Incorporated. BAS19-7-F offers a wider operating temperature range (-65°C to 150°C versus -55°C to 150°C). Selection depends on temperature requirements and preferred supplier.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements.
