Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Vishay eSMP® Series): Parts SL03-GS08, SL03-GS18, and SL03-M-08 are direct parametric equivalents manufactured by Vishay. These devices maintain identical electrical specifications across all critical parameters: 30 V reverse voltage, 1.1 A average rectified current, 430 mV forward voltage at 1.1 A, 10 ns reverse recovery time, and 130 µA reverse leakage current at 30 V. All three parts are housed in DO-219AB (SMF) surface mount packages. Differentiation among these equivalents is based solely on packaging format: SL03-M-18 and SL03-GS18 are supplied in Tape & Reel (TR), while SL03-GS08 and SL03-M-08 are supplied in Cut Tape (CT) & Digi-Reel® format.

Manufacturer Recommended Alternatives (Cross-Manufacturer): Parts CRS05(TE85L,Q,M), MBR130LSFT1G, and PMEG3015EH,115 are manufacturer-recommended alternatives from Toshiba, onsemi, and Nexperia respectively. These alternatives maintain the 30 V reverse voltage specification but differ in current rating, forward voltage characteristics, package configuration, and operating temperature ranges. Selection among these alternatives requires evaluation of specific application requirements within the allowed parameter ranges.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): 30 V (fixed requirement)
Current - Average Rectified (Io): 1.1 A (parametric equivalents) or 1.0 A to 1.5 A (alternatives)
Technology: Schottky (fixed requirement)
Mounting Type: Surface Mount (fixed requirement)
RoHS Status: ROHS3 Compliant (fixed requirement)

Engineering Selection Recommendations

Parametric Equivalent Selection (Vishay eSMP® Series):

SL03-GS18 and SL03-M-08 are direct parametric equivalents to SL03-M-18 with identical electrical performance across all specified parameters. Selection between these three Vishay parts is determined by packaging format requirements:

Frequently Asked Questions (FAQ)

Q: Can SL03-GS08 be used as a direct replacement for SL03-M-18?

A: Yes. SL03-GS08 is a parametric equivalent with identical electrical specifications: 30 V reverse voltage, 1.1 A average rectified current, 430 mV forward voltage at 1.1 A, and 130 µA reverse leakage current at 30 V. Both devices are housed in DO-219AB (SMF) surface mount packages. The only difference is packaging format: SL03-M-18 is supplied in Tape & Reel (TR) while SL03-GS08 is supplied in Cut Tape (CT) & Digi-Reel®. Selection depends on assembly process requirements.

Q: What is the difference between SL03-M-18 and SL03-GS18?

A: SL03-M-18 and SL03-GS18 are parametric equivalents with identical electrical specifications and both are supplied in Tape & Reel (TR) format. Both are housed in DO-219AB (SMF) packages. The parts differ only in manufacturer designation within the Vishay product line. Both maintain ROHS3 compliance and MSL 1 (Unlimited) rating.

Q: Can CRS05(TE85L,Q,M) replace SL03-M-18 in all applications?

A: CRS05(TE85L,Q,M) maintains the 30 V reverse voltage specification but differs in current rating (1.0 A versus 1.1 A), forward voltage (450 mV @ 1 A versus 430 mV @ 1.1 A), and package format (SOD-123F versus DO-219AB). Application compatibility depends on whether the circuit can operate within these electrical parameter differences and whether the SOD-123F package footprint is acceptable for the PCB layout.

Q: What are the advantages of PMEG3015EH,115 as an alternative?

A: PMEG3015EH,115 provides higher current capacity at 1.5 A average rectified current compared to the 1.1 A rating of SL03-M-18. It offers extended operating temperature to 150°C maximum junction temperature. The device carries Automotive grade qualification with AEC-Q100 certification. Inventory availability is significantly higher at 144,808 pieces. Trade-offs include higher forward voltage (550 mV @ 1.5 A) and different package format (SOD-123F).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed—SL03-GS08, SL03-GS18, SL03-M-08, CRS05(TE85L,Q,M), MBR130LSFT1G, and PMEG3015EH,115—are ROHS3 compliant. All maintain MSL 1 (Unlimited) moisture sensitivity level rating.

Q: What is the significance of the DO-219AB package versus SOD-123F?

A: DO-219AB (SMF) and SOD-123F are distinct surface mount package formats with different physical dimensions and PCB footprints. SL03-M-18 uses DO-219AB, while CRS05(TE85L,Q,M), MBR130LSFT1G, and PMEG3015EH,115 use SOD-123F. Package compatibility requires verification that the substitute part's footprint matches the PCB design. These packages are not mechanically interchangeable.

Q: Which substitute offers the lowest forward voltage drop?

A: MBR130LSFT1G offers the lowest forward voltage drop at 380 mV @ 1 A. However, this part is rated for 1.0 A average rectified current, lower than the 1.1 A rating of SL03-M-18. Forward voltage comparison must account for the different current ratings at which measurements are specified.

Q: Can I use SL03-M-08 instead of SL03-M-18?

A: Yes. SL03-M-08 is a parametric equivalent with identical electrical specifications to SL03-M-18. Both are rated for 30 V reverse voltage, 1.1 A average rectified current, 430 mV forward voltage at 1.1 A, and 130 µA reverse leakage current at 30 V. Both use DO-219AB (SMF) packages. The difference is packaging format: SL03-M-18 is Tape & Reel (TR) while SL03-M-08 is Cut Tape (CT) & Digi-Reel®.

Q: What is the operating temperature range difference between alternatives?

A: SL03-M-18, SL03-GS08, SL03-GS18, SL03-M-08, and MBR130LSFT1G are rated to 125°C maximum junction temperature. CRS05(TE85L,Q,M) and PMEG3015EH,115 extend to 150°C maximum junction temperature. Applications requiring operation at elevated temperatures may benefit from the extended temperature rating of the Toshiba and Nexperia alternatives.

Q: Is reverse recovery time specified for all substitute parts?

A: Reverse recovery time (trr) of 10 ns is specified for SL03-M-18, SL03-GS18, and SL03-M-08. This parameter is not provided for SL03-GS08, CRS05(TE85L,Q,M), MBR130LSFT1G, or PMEG3015EH,115 in the available data. All parts are specified as Fast Recovery with speed ≤ 500ns for currents > 200mA (Io).
