Substitute Part Grouping Explanation

Substitution of the BAV99LT116 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Critical for Functional Equivalence):

• Diode Configuration: 1 Pair Series Connection
• Voltage - DC Reverse (Vr) (Max): 75 V
• Current - Average Rectified (Io) (per Diode): 215 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 150 mA
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 4 ns

Mechanical Parameters (Critical for Physical Compatibility):

• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, SOT-23-3

Environmental & Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The ABAV99-HF manufactured by Comchip Technology meets all critical electrical and mechanical parameters specified for the BAV99LT116, establishing it as a parametric equivalent substitute part.

Parameter Comparison

Engineering Selection Recommendations

The ABAV99-HF is a direct parametric equivalent to the BAV99LT116 across all critical electrical and mechanical specifications. The substitute part maintains identical voltage ratings, current capacity, switching speed characteristics, and package form factor.

Product Status Consideration: The BAV99LT116 is classified as Obsolete, while the ABAV99-HF maintains Active product status. This status differential establishes the ABAV99-HF as the appropriate selection for new designs and ongoing production support.

Compliance & Certification: Both parts are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent environmental handling and regulatory compliance. The ABAV99-HF carries AEC-Q101 Automotive qualification and EAR99 ECCN classification, providing additional qualification documentation for applications requiring automotive-grade component certification.

Reverse Leakage Differential: The ABAV99-HF exhibits a reverse leakage current of 2.5 µA @ 75 V compared to 1 µA @ 75 V for the BAV99LT116. This differential remains within acceptable tolerance for general-purpose diode array applications and does not restrict substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Can the ABAV99-HF be used as a direct replacement for the BAV99LT116 in existing circuit designs?

A: Yes. The ABAV99-HF meets all critical electrical parameters (voltage rating, current capacity, switching speed, forward voltage) and mechanical specifications (Surface Mount, TO-236-3/SOT-23-3 package) required for direct substitution. No circuit modifications are necessary.

Q: What is the significance of the reverse leakage current difference between the two parts?

A: The ABAV99-HF exhibits 2.5 µA reverse leakage at 75 V compared to 1 µA for the BAV99LT116. This 1.5 µA differential is negligible for general-purpose rectification and switching applications and does not impact circuit performance or reliability.

Q: Are there packaging differences between the BAV99LT116 and ABAV99-HF?

A: Both parts use identical Surface Mount packaging: TO-236-3, SC-59, SOT-23-3. The ABAV99-HF is supplied in Tape & Reel (TR) format, which is standard for high-volume production. No PCB layout or assembly process modifications are required.

Q: Does the ABAV99-HF carry automotive qualification?

A: Yes. The ABAV99-HF is qualified to AEC-Q101 automotive standards and carries Grade Automotive designation. This qualification is not present in the BAV99LT116 specification. Applications requiring automotive-grade components benefit from this additional certification.

Q: Why is the BAV99LT116 classified as Obsolete?

A: The BAV99LT116 is no longer in active production. The ABAV99-HF represents the current-generation equivalent part available from active inventory. Transition to the ABAV99-HF ensures continued supply chain access and production support.

Q: Are both parts RoHS compliant?

A: Yes. Both the BAV99LT116 and ABAV99-HF are ROHS3 Compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, meeting equivalent environmental and regulatory requirements.
