S1GFS MWG Equivalent & Substitute Parts

Part Overview

The S1GFS MWG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, classified as a standard recovery diode in the SOD-128 surface mount package. This component operates at 400 V DC reverse voltage with 1 A average rectified current capacity, suitable for standard power conversion and protection applications. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and application-specific requirements such as automotive qualification or alternative packaging formats.

Substitute Part Grouping Explanation

Substitution eligibility for the S1GFS MWG is determined by electrical parameter equivalence and mechanical compatibility. All identified substitute parts maintain identical electrical specifications: 400 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop at 1 A, standard recovery characteristics, and SOD-128 surface mount packaging. The substitution logic is organized into two categories:

Category 1: Parametric Equivalents (Standard Grade) Parts meeting all electrical and mechanical parameters without automotive qualification. S1GFS represents the base parametric equivalent with Tape & Reel packaging.

Category 2: Parametric Equivalents (Automotive Grade) Parts meeting all electrical and mechanical parameters with AEC-Q101 automotive qualification. S1GFSH (Tape & Reel) and S1GFSHMWG (Cut Tape) provide automotive-qualified alternatives with identical electrical performance.

Packaging Variation S1GFSHMWG differs from S1GFSH only in packaging format (Cut Tape versus Tape & Reel), maintaining all electrical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications S1GFS and S1GFS MWG are functionally equivalent and interchangeable for non-automotive applications. Both maintain identical electrical performance and RoHS3 compliance. Selection between these parts is determined by packaging and inventory availability rather than technical performance.

For Automotive Applications S1GFSH and S1GFSHMWG are required when AEC-Q101 automotive qualification is specified. These parts maintain all electrical parameters of the standard grade while providing automotive-grade reliability certification. Both automotive variants are suitable for automotive circuit protection and power conversion applications.

For Packaging-Specific Requirements S1GFSHMWG (Cut Tape) provides an alternative to Tape & Reel formats when manual or semi-automated assembly processes are employed. Electrical and thermal performance remain identical to S1GFSH (Tape & Reel).

Compliance Considerations All substitute parts maintain Active product status, ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating. No compliance trade-offs exist between the main part and any substitute.

Frequently Asked Questions (FAQ)

Q: Can S1GFS be used as a direct replacement for S1GFS MWG? A: Yes. S1GFS and S1GFS MWG are parametric equivalents with identical electrical specifications, reverse voltage, current rating, forward voltage drop, and operating temperature range. The difference is packaging format (Tape & Reel). Direct substitution is valid for non-automotive applications.

Q: What is the difference between S1GFSH and S1GFSHMWG? A: S1GFSH and S1GFSHMWG are electrically identical. The only difference is packaging format: S1GFSH is supplied in Tape & Reel format, while S1GFSHMWG is supplied in Cut Tape format. Both carry AEC-Q101 automotive qualification.

Q: When should I use the automotive-qualified variants (S1GFSH or S1GFSHMWG)? A: Automotive-qualified variants are required when the application specifies AEC-Q101 certification or when the component is used in automotive circuit protection, power conversion, or safety-critical functions. Standard grade parts (S1GFS, S1GFS MWG) do not carry automotive qualification.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts—S1GFS, S1GFSH, and S1GFSHMWG—are ROHS3 compliant with REACH unaffected status. No environmental compliance differences exist between the main part and substitutes.

Q: Can I substitute S1GFS MWG with S1GFSHMWG in an automotive application? A: Yes, provided the application requires AEC-Q101 automotive qualification. S1GFSHMWG provides automotive qualification with identical electrical performance. The only difference is packaging format (Cut Tape versus Tape & Reel).

Q: What parameters determine substitution eligibility? A: Substitution eligibility is determined by: (1) Voltage - DC Reverse (Vr) rating of 400 V, (2) Current - Average Rectified (Io) of 1 A, (3) Forward voltage drop of 1.1 V @ 1 A, (4) Standard recovery speed characteristics, (5) SOD-128 surface mount package, and (6) Operating temperature range of -55°C to 150°C. All substitute parts meet these criteria.

Q: Is there a performance difference between Tape & Reel and Cut Tape packaging? A: No. Tape & Reel and Cut Tape are packaging and delivery formats only. Electrical performance, thermal characteristics, and reliability are identical. Selection is based on assembly process requirements and inventory management.
