Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S1GLW are identified based on electrical parameter equivalence and mechanical compatibility. The primary substitution criteria are:

Electrical Parameters:

• 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)

Mechanical Parameters:

• Package / Case: SOD-123W
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all electrical and mechanical criteria are classified as parametric equivalents. Parts meeting these criteria with additional specifications (such as automotive qualification) are classified as similar manufacturers' parts with extended capability.

Parameter Comparison

Engineering Selection Recommendations

S1GLWH (Taiwan Semiconductor Corporation): This part is a parametric equivalent to the S1GLW, manufactured by the same supplier. Both parts share identical electrical specifications, package form factor, and compliance certifications. The S1GLWH is suitable for direct substitution in applications where the S1GLW is specified. Higher inventory availability (29,532 pcs) supports procurement continuity.

PNS40010ER,115 (Nexperia USA Inc.): This part meets all electrical and mechanical substitution criteria and is supplied in Cut Tape (CT) & Digi-Reel® packaging. The PNS40010ER,115 carries AEC-Q100 automotive qualification and Automotive grade designation, indicating suitability for automotive applications. This part is appropriate for substitution in applications requiring automotive-grade reliability or where Nexperia supply chain preference exists. Packaging format differs from the main part (Cut Tape vs. Tape & Reel), requiring process compatibility verification.

All three parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, supporting deployment in standard manufacturing environments without additional handling requirements.

Frequently Asked Questions (FAQ)

Q: Can S1GLWH be used as a direct replacement for S1GLW?

A: Yes. The S1GLWH is a parametric equivalent manufactured by Taiwan Semiconductor Corporation with identical electrical specifications (400 V, 1 A, 1.1 V forward voltage), identical package (SOD-123W), and identical compliance certifications. Direct substitution is supported without circuit modification.

Q: What is the difference between S1GLWH and PNS40010ER,115?

A: Both parts meet the core electrical and mechanical substitution criteria. The primary differences are: (1) Manufacturer: Taiwan Semiconductor vs. Nexperia USA Inc.; (2) Packaging: Tape & Reel vs. Cut Tape & Digi-Reel®; (3) Qualification: PNS40010ER,115 carries AEC-Q100 automotive qualification. The PNS40010ER,115 is suitable for automotive applications; packaging format requires process compatibility assessment.

Q: Are there temperature rating differences between these parts?

A: All three parts specify maximum junction operating temperature of 175°C. The S1GLW and S1GLWH specify the full range as -55°C to 175°C; the PNS40010ER,115 specifies 175°C maximum. Operating temperature capability is equivalent for standard industrial applications.

Q: Does packaging format affect substitution?

A: Yes. The S1GLW and S1GLWH are supplied in Tape & Reel (TR) format. The PNS40010ER,115 is supplied in Cut Tape (CT) & Digi-Reel® format. Substitution requires verification that assembly equipment and processes support the alternate packaging format.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, supporting use in applications with environmental compliance requirements.

Q: What is the reverse recovery time specification?

A: The S1GLW and S1GLWH do not specify reverse recovery time (trr). The PNS40010ER,115 specifies 1.8 µs reverse recovery time. For applications sensitive to reverse recovery characteristics, the PNS40010ER,115 provides explicit specification; the S1GLW and S1GLWH meet standard recovery speed classification (>500ns, >200mA).

Q: Can these parts be used interchangeably in automotive applications?

A: The PNS40010ER,115 carries AEC-Q100 qualification and Automotive grade designation, supporting direct use in automotive applications. The S1GLW and S1GLWH do not carry automotive qualification; use in automotive applications requires design review and qualification assessment.
