S1GLHRFG Equivalent & Substitute Parts

Part Overview

The S1GLHRFG 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 Sub SMA surface mount package. This component is classified as Active product status and carries AEC-Q101 automotive qualification with ROHS3 compliance.

Substitute parts become necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when design requirements permit alternative packaging configurations. The S1GLHRFG maintains identical electrical performance specifications across qualified substitute options, enabling direct functional replacement within specified application parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1GLHRFG is determined by electrical and mechanical parameter equivalence. All substitute parts must maintain identical specifications across the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Reverse Recovery Time (trr): 1.8 µs
• Current - Reverse Leakage @ Vr: 5 µA @ 400 V
• Capacitance @ Vr, F: 9 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 175°C
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Technology: Standard

The S1GL qualifies as a parametric equivalent substitute. This part maintains all electrical specifications and physical package requirements identical to the S1GLHRFG. The primary distinction is packaging configuration (Tape & Reel versus standard packaging) and product status classification (Not For New Designs). Electrical performance and thermal characteristics remain unchanged, permitting direct functional substitution in existing designs.

Engineering Selection Recommendations

S1GLHRFG (Primary Selection)

The S1GLHRFG is the recommended selection for new designs and active production. This part carries Active product status, indicating ongoing manufacturer support and availability. AEC-Q101 automotive qualification certifies compliance with automotive reliability standards. ROHS3 compliance and REACH unaffected status satisfy environmental and regulatory requirements. Standard packaging configuration provides flexibility for both prototype and production volume applications.

S1GL (Substitute Selection)

The S1GL qualifies as a parametric equivalent substitute when S1GLHRFG availability is constrained or when Tape & Reel packaging configuration aligns with production requirements. This part maintains identical electrical specifications and thermal operating range. However, S1GL carries Not For New Designs product status, indicating the manufacturer does not recommend this part for new design implementations. Use of S1GL is appropriate for sustaining production of existing designs or as a temporary supply solution during S1GLHRFG allocation periods. ROHS3 compliance and REACH unaffected status are maintained. Verify Tape & Reel packaging compatibility with assembly equipment and processes before implementation.

Frequently Asked Questions (FAQ)

Q: Can S1GL be used as a direct replacement for S1GLHRFG in new designs?

A: S1GL maintains identical electrical and thermal specifications. However, S1GL carries Not For New Designs product status. For new designs, S1GLHRFG is the appropriate selection. S1GL is suitable for sustaining production of existing designs when S1GLHRFG supply is unavailable.

Q: What is the difference between S1GLHRFG and S1GL packaging?

A: S1GLHRFG is supplied in standard packaging configuration. S1GL is supplied in Tape & Reel (TR) format. Both parts use identical DO-219AB package and Sub SMA supplier device package. Verify that assembly equipment supports Tape & Reel format before selecting S1GL.

Q: Are the electrical specifications identical between S1GLHRFG and S1GL?

A: Yes. Both parts specify 400 V DC reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, 1.8 µs reverse recovery time, 5 µA reverse leakage current at 400 V, and 9 pF capacitance at 4V, 1MHz. Operating temperature range is -55°C to 175°C for both parts.

Q: Does S1GL have AEC-Q101 qualification?

A: AEC-Q101 qualification is specified for S1GLHRFG. Qualification status for S1GL is not provided in the available technical data. Confirm automotive qualification requirements with the manufacturer before selecting S1GL for automotive applications.

Q: What compliance certifications apply to both parts?

A: Both S1GLHRFG and S1GL are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts, indicating no moisture sensitivity restrictions.

Q: Can S1GL be used in automotive applications?

A: S1GLHRFG carries AEC-Q101 automotive qualification. S1GL qualification status for automotive applications is not specified. Confirm automotive qualification and compliance requirements with the manufacturer before using S1GL in automotive designs.
