S1GFSHMWG Equivalent & Substitute Parts

Part Overview

The S1GFSHMWG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-128 package. This component is classified as Active product status and meets automotive-grade specifications with AEC-Q101 qualification. Substitute parts are identified when equivalent electrical characteristics and mechanical compatibility are maintained across the same package footprint and performance envelope, enabling design flexibility and supply chain optimization.

Substitute Part Grouping Explanation

Substitute parts for the S1GFSHMWG are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Current - Reverse Leakage @ Vr: 1 µA @ 400 V
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Capacitance @ Vr, F: 9 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C ~ 150°C

Mechanical Parameters (Must Match):

• Package / Case: SOD-128
• Mounting Type: Surface Mount
• Supplier Device Package: SOD-128

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• Manufacturer: Taiwan Semiconductor Corporation

The primary difference between the main part and substitutes is packaging format: the S1GFSHMWG is supplied in Cut Tape (CT), while substitute parts S1GFS and S1GFSH are supplied in Tape & Reel (TR) format. All other electrical, mechanical, and compliance specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

S1GFSHMWG (Main Part): Suitable for applications requiring Cut Tape packaging format. Maintains Active product status with full automotive-grade specifications and AEC-Q101 qualification. ROHS3 compliant with unlimited moisture sensitivity rating.

S1GFS (Substitute): Electrically and mechanically equivalent to the main part. Supplied in Tape & Reel format for high-volume production environments. Active product status with ROHS3 compliance. Note: Automotive grade and AEC-Q101 qualification are not specified for this variant.

S1GFSH (Substitute): Electrically and mechanically equivalent to the main part. Supplied in Tape & Reel format. Maintains automotive-grade specifications and AEC-Q101 qualification matching the main part. Active product status with ROHS3 compliance. Suitable for applications requiring automotive qualification in high-volume packaging.

Selection between these parts depends on packaging requirements and supply chain logistics. All three parts share identical electrical performance and thermal operating range. For automotive applications requiring AEC-Q101 qualification, S1GFSHMWG and S1GFSH are appropriate selections.

Frequently Asked Questions (FAQ)

Q: Can S1GFS be used as a direct replacement for S1GFSHMWG?

A: S1GFS is electrically and mechanically equivalent to S1GFSHMWG. The primary difference is packaging format: S1GFS is supplied in Tape & Reel (TR) while S1GFSHMWG is supplied in Cut Tape (CT). Both parts are identical in electrical performance, thermal range, and compliance status. However, S1GFS does not specify automotive grade or AEC-Q101 qualification. For non-automotive applications, S1GFS is a direct substitute. For automotive applications requiring AEC-Q101 qualification, S1GFSH is the appropriate substitute.

Q: What is the difference between S1GFSH and S1GFS?

A: S1GFSH and S1GFS are both supplied in Tape & Reel format and share identical electrical specifications. The key difference is that S1GFSH specifies automotive grade and AEC-Q101 qualification, while S1GFS does not. Both parts are electrically equivalent to S1GFSHMWG.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the SOD-128 package with surface mount mounting type. PCB footprints are identical across S1GFSHMWG, S1GFS, and S1GFSH.

Q: What does the packaging format difference mean for component procurement?

A: Cut Tape (CT) packaging is typically used for lower-volume or manual assembly applications, while Tape & Reel (TR) packaging is optimized for automated high-volume production. The electrical and mechanical performance of the diode is identical regardless of packaging format.

Q: Are all three parts RoHS compliant?

A: Yes. S1GFSHMWG, S1GFS, and S1GFSH are all ROHS3 compliant with REACH Unaffected status.

Q: What is the operating temperature range for these diodes?

A: The junction operating temperature range for all three parts is -55°C to 150°C.

Q: Can these parts be used in automotive applications?

A: S1GFSHMWG and S1GFSH are specified as automotive-grade with AEC-Q101 qualification and are suitable for automotive applications. S1GFS does not specify automotive grade or AEC-Q101 qualification and should not be used in applications requiring automotive qualification.
