SGL41-20/96 Equivalent & Substitute Parts
Part Overview
The SGL41-20/96 is a Schottky rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 20 V DC reverse voltage and 1 A average rectified current in a surface mount DO-213AB (MELF) package. This part is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts satisfy the same functional requirements within specified parameter tolerances.

Engineering Selection Recommendations
Primary Substitutes (Vishay General Semiconductor - Diodes Division):
The BYM13-20-E3/96, BYM13-20-E3/97, BYM13-20HE3/96, BYM13-20HE3/97, SGL41-20-E3/96, SGL41-20-E3/97, SGL41-20HE3/96, and SGL41-20HE3/97 parts are direct parametric equivalents to the SGL41-20/96. All maintain identical electrical specifications (20 V reverse voltage, 1 A average rectified current, 500 mV forward voltage drop at 1 A, 500 µA reverse leakage at 20 V, and 110 pF capacitance at 4 V, 1 MHz) and mechanical compatibility (DO-213AB surface mount package, -55°C to 125°C operating temperature range). All primary substitutes carry active product status and RoHS3 compliance, providing regulatory advantage over the obsolete SGL41-20/96. Inventory availability ranges from 798 to 7900 pieces across these variants.
Secondary Substitutes (Microchip Technology):
The CDLL1A20 and CDLL5817 parts satisfy the core functional requirements of 20 V reverse voltage and 1 A average rectified current in DO-213AB surface mount packages. These Microchip alternatives exhibit higher forward voltage drop (600 mV @ 1 A versus 500 mV @ 1 A) and lower reverse leakage current (100 µA @ 20 V versus 500 µA @ 20 V). The CDLL1A20 exhibits significantly lower capacitance (0.9 pF @ 5 V, 1 MHz versus 110 pF @ 4 V, 1 MHz). Both Microchip parts maintain RoHS non-compliant status, matching the original SGL41-20/96. These alternatives are suitable for applications where the electrical parameter variations are acceptable within circuit design margins.
Compliance Considerations:
For new designs or applications requiring RoHS3 compliance, selection from the Vishay BYM13 or SGL41 active series is required. For legacy system maintenance where RoHS compliance is not mandated, Microchip CDLL alternatives provide functional substitution with different electrical characteristics.
Frequently Asked Questions (FAQ)
Q: Can BYM13-20-E3/96 directly replace SGL41-20/96 in existing designs?
A: Yes. The BYM13-20-E3/96 maintains identical electrical specifications (20 V reverse voltage, 1 A average rectified current, 500 mV forward voltage drop at 1 A, 500 µA reverse leakage at 20 V, 110 pF capacitance at 4 V, 1 MHz) and mechanical compatibility (DO-213AB surface mount package, -55°C to 125°C operating temperature). The primary difference is product status (active versus obsolete) and RoHS3 compliance.
Q: What is the difference between BYM13-20-E3/96 and BYM13-20-E3/97?
A: Both parts are parametrically identical in electrical and mechanical specifications. The suffix designations (/96 and /97) indicate different manufacturing date codes or tape reel configurations. Selection between these variants depends on procurement requirements and inventory availability.
Q: Are Microchip CDLL1A20 and CDLL5817 suitable replacements?
A: The Microchip parts satisfy the core voltage and current ratings (20 V reverse voltage, 1 A average rectified current) and package requirements (DO-213AB surface mount). However, they exhibit different electrical characteristics: forward voltage drop of 600 mV @ 1 A (versus 500 mV @ 1 A) and reverse leakage current of 100 µA @ 20 V (versus 500 µA @ 20 V). The CDLL1A20 also exhibits significantly lower capacitance (0.9 pF @ 5 V, 1 MHz versus 110 pF @ 4 V, 1 MHz). These differences must be evaluated against circuit design margins and performance requirements.
Q: What is the significance of the "HE3" designation in part numbers like BYM13-20HE3/96?
A: The "HE3" designation indicates a specific product variant within the Vishay catalog. All HE3 variants maintain identical electrical and mechanical specifications to their non-HE3 counterparts (BYM13-20-E3/96 versus BYM13-20HE3/96). Selection depends on availability and procurement specifications.
Q: Why does the original SGL41-20/96 show obsolete status?
A: The SGL41-20/96 is classified as obsolete, indicating it is no longer in active production. Active equivalent parts (BYM13-20-E3/96, BYM13-20-E3/97, SGL41-20-E3/96, SGL41-20-E3/97, and their HE3 variants) provide continued design support and procurement continuity.
Q: Are all substitute parts RoHS3 compliant?
A: No. Vishay BYM13 and SGL41 active series parts are RoHS3 compliant. Microchip CDLL1A20 and CDLL5817 parts are RoHS non-compliant. Selection depends on regulatory requirements for the target application.
Q: What packaging options are available for these substitutes?
A: Vishay BYM13-20-E3/96, BYM13-20-E3/97, SGL41-20-E3/96, and SGL41-20-E3/97 are supplied in Tape & Reel (TR) packaging. Vishay BYM13-20HE3/96, BYM13-20HE3/97, SGL41-20HE3/96, and SGL41-20HE3/97 are supplied without specified packaging designation. Microchip CDLL1A20 and CDLL5817 are supplied in Bulk packaging. Packaging selection affects procurement and assembly processes.
Q: Which substitute offers the best inventory availability?
A: BYM13-20-E3/96 offers the highest inventory availability at 7900 pieces. SGL41-20-E3/96 provides 2800 pieces. Other variants range from 798 to 1135 pieces. Microchip alternatives provide 855 to 1103 pieces.
