Key Parameters

Substitute Part Grouping Explanation

Substitution of the LL101C-7 is determined by electrical and mechanical compatibility within the Schottky diode category. The primary substitution criteria are:

Parametric Equivalence Requirements:

• Voltage - DC Reverse (Vr) rating must equal or exceed 40 V
• Current - Average Rectified (Io) rating must equal or exceed 30 mA
• Package / Case must be DO-213AC, MINI-MELF, or SOD-80
• Mounting Type must be Surface Mount
• Technology must be Schottky

Substitute Classification:

Parametric Equivalent: LL101C-GS08 matches all electrical parameters and package specifications of the LL101C-7 while offering active product status and improved inventory availability.

Manufacturer Recommended: BAS86,115 exceeds the electrical specifications of the LL101C-7 with higher voltage (50 V), current (200 mA), and reverse recovery time (4 ns) ratings. This part is compatible with the same package family and mounting type, providing enhanced performance margins for applications requiring higher current or voltage headroom.

Engineering Selection Recommendations

LL101C-GS08 Selection Criteria:

The LL101C-GS08 is the direct parametric equivalent to the LL101C-7. This part maintains identical electrical specifications including 40 V reverse voltage, 30 mA average rectified current, 390 mV forward voltage at 1 mA, and 1 ns reverse recovery time. The LL101C-GS08 is classified as active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant, AEC-Q101 qualified (automotive grade), and carry MSL 1 (Unlimited) moisture sensitivity ratings. The LL101C-GS08 is supplied in Tape & Reel (TR) packaging with significantly higher inventory availability (2977 Pcs vs. 964 Pcs for the obsolete LL101C-7).

BAS86,115 Selection Criteria:

The BAS86,115 is a manufacturer-recommended substitute offering enhanced electrical performance. This part exceeds the LL101C-7 specifications with 50 V reverse voltage (vs. 40 V), 200 mA average rectified current (vs. 30 mA), and maintains the same 125°C maximum junction temperature. The BAS86,115 is active product status with extensive inventory availability (16998 Pcs). This part is suitable for applications requiring higher current capacity or voltage margin while maintaining surface mount SOD-80 MiniMELF package compatibility. The BAS86,115 is ROHS3 compliant and carries MSL 1 (Unlimited) rating. Selection of this part introduces higher reverse leakage current (5 µA @ 40 V vs. 200 nA @ 30 V) and increased capacitance (8 pF @ 1V vs. 2.2 pF @ 0V), which may affect high-frequency circuit performance.

Frequently Asked Questions (FAQ)

Q: Can LL101C-GS08 be used as a direct replacement for LL101C-7?

A: Yes. The LL101C-GS08 is a parametric equivalent with identical electrical specifications and package configuration. Both parts are Schottky diodes rated for 40 V reverse voltage, 30 mA average rectified current, and surface mount SOD-80 MiniMELF packaging. The primary difference is product status: LL101C-GS08 is active while LL101C-7 is obsolete.

Q: What are the differences between LL101C-GS08 and BAS86,115?

A: Both parts are Schottky diodes in surface mount SOD-80 MiniMELF packages. LL101C-GS08 matches the LL101C-7 specifications exactly (40 V, 30 mA). BAS86,115 provides higher ratings: 50 V reverse voltage and 200 mA average rectified current. BAS86,115 has higher reverse leakage current (5 µA @ 40 V) and capacitance (8 pF @ 1V) compared to both LL101C-7 and LL101C-GS08.

Q: Is BAS86,115 a drop-in replacement for LL101C-7?

A: BAS86,115 is mechanically compatible (same SOD-80 MiniMELF package and surface mount configuration) and electrically superior in voltage and current ratings. However, it is not a parametric equivalent due to higher reverse leakage current and capacitance. BAS86,115 is suitable for applications where the LL101C-7 specifications are met or exceeded, but circuit performance at high frequencies may differ due to increased capacitance.

Q: Are all three parts RoHS compliant?

A: Yes. LL101C-7, LL101C-GS08, and BAS86,115 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the difference in packaging between LL101C-7 and LL101C-GS08?

A: LL101C-7 is supplied in standard packaging (not specified in detail). LL101C-GS08 is supplied in Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging options. Both use the same SOD-80 MiniMELF component package for surface mount assembly.

Q: Can I use BAS86,115 in a circuit designed for LL101C-7 if the current requirement is only 30 mA?

A: BAS86,115 is electrically compatible for 30 mA operation since its 200 mA rating exceeds this requirement. However, the higher reverse leakage current (5 µA @ 40 V vs. 200 nA @ 30 V) and capacitance (8 pF @ 1V vs. 2.2 pF @ 0V) may affect circuit behavior in sensitive applications, particularly in high-frequency or low-leakage-critical designs.

Q: Why is LL101C-7 obsolete?

A: The LL101C-7 is classified as obsolete by Vishay General Semiconductor - Diodes Division. The LL101C-GS08 provides equivalent functionality with active product status and improved availability.
