LL101C-13 Equivalent & Substitute Parts

Part Overview

The LL101C-13 is a Schottky diode rated for 40 V DC reverse voltage with 30 mA average rectified current in a surface mount SOD-80 MiniMELF package. Manufactured by Vishay General Semiconductor - Diodes Division, this component is qualified to AEC-Q101 automotive standards and complies with RoHS3 and REACH regulations.

The LL101C-13 is classified as obsolete. Substitute parts are necessary to maintain design continuity and ensure component availability for new production and field service applications. Alternative models within the LL101 series provide equivalent electrical performance with active product status and improved supply chain availability.

Substitute Part Grouping Explanation

Substitute parts for the LL101C-13 are selected based on strict electrical and mechanical parameter equivalence within the Vishay LL101 series. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 30 mA
• Reverse Recovery Time (trr): 1 ns
• Current - Reverse Leakage @ Vr: 200 nA @ 30 V
• Capacitance @ Vr, F: 2.2 pF @ 0 V, 1 MHz
• Operating Temperature - Junction (Max): 125°C
• Technology: Schottky
• Speed Classification: Small Signal ≤ 200 mA (Io), Any Speed

Mechanical Parameters (Must Match):

• Package / Case: DO-213AC, MINI-MELF, SOD-80
• Mounting Type: Surface Mount
• Supplier Device Package: SOD-80 MiniMELF

Compliance Parameters (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts may differ in packaging format (Tape & Reel, Cut Tape, Digi-Reel) and product status (Active vs. Obsolete), provided all electrical, mechanical, and compliance parameters remain equivalent.

Engineering Selection Recommendations

LL101C-GS08 is the primary substitute for LL101C-13. This part maintains identical electrical characteristics, including forward voltage specification (390 mV @ 1 mA), and is available in Cut Tape and Digi-Reel packaging formats. LL101C-GS08 holds active product status with Vishay General Semiconductor - Diodes Division, ensuring long-term availability and supply chain stability. The part retains full automotive grade qualification (AEC-Q101), RoHS3 compliance, and MSL 1 rating.

LL101C-GS18 is an alternative substitute with active product status, available in Tape & Reel packaging. This part meets all electrical, mechanical, and compliance requirements. The forward voltage specification differs (900 mV @ 15 mA versus 390 mV @ 1 mA), reflecting measurement at different current levels. Both specifications remain within the Schottky diode performance envelope for this voltage and current class.

Both substitute parts are manufactured by the same supplier, use identical package geometry (SOD-80 MiniMELF), and carry equivalent automotive qualifications. Selection between LL101C-GS08 and LL101C-GS18 depends on packaging requirements and supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can LL101C-GS08 or LL101C-GS18 be used as direct replacements for LL101C-13 in existing designs?

A: Yes. Both substitute parts are electrically and mechanically equivalent to LL101C-13. All critical parameters—reverse voltage rating, average rectified current, reverse recovery time, leakage current, and capacitance—are identical. Package geometry (SOD-80 MiniMELF) and mounting type (surface mount) are identical, enabling direct PCB-level substitution.

Q: What is the difference between LL101C-GS08 and LL101C-GS18?

A: The primary differences are packaging format and forward voltage measurement conditions. LL101C-GS08 is supplied in Cut Tape and Digi-Reel formats, while LL101C-GS18 is supplied in Tape & Reel format. Forward voltage is specified at 390 mV @ 1 mA for LL101C-GS08 and 900 mV @ 15 mA for LL101C-GS18. Both measurements are valid for Schottky diodes and reflect standard industry test conditions at different current levels.

Q: Why is LL101C-13 classified as obsolete?

A: LL101C-13 is no longer in active production. Vishay General Semiconductor - Diodes Division has transitioned to active variants within the LL101 series (LL101C-GS08 and LL101C-GS18) that provide equivalent performance with improved supply availability.

Q: Are all three parts (LL101C-13, LL101C-GS08, LL101C-GS18) automotive qualified?

A: Yes. All three parts carry automotive grade classification and AEC-Q101 qualification from Vishay General Semiconductor - Diodes Division. All are RoHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which packaging format should I select for new production?

A: LL101C-GS08 (Cut Tape and Digi-Reel) and LL101C-GS18 (Tape & Reel) are both suitable for automated assembly. Selection depends on your production equipment compatibility and supply chain logistics. Both formats are standard for surface mount diode assembly.

Q: Are there any thermal or performance differences between the substitute parts?

A: No. All three parts have identical maximum junction temperature (125°C), reverse recovery time (1 ns), leakage current (200 nA @ 30 V), and capacitance (2.2 pF @ 0 V, 1 MHz). Thermal and switching performance are equivalent.
