S1JL Equivalent & Substitute Parts

Part Overview

The S1JL is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 1 A average rectified current. This surface mount diode is packaged in the Sub SMA (DO-219AB) form factor and is designed for standard recovery applications. The part is Active in product status and fully compliant with RoHS3 and REACH regulations.

Substitute parts are identified to address specific application requirements including alternative packaging formats, inventory availability, and parametric equivalence across Taiwan Semiconductor Corporation's S1J diode series.

Substitute Part Grouping Explanation

Substitute parts for the S1JL are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Same Package - DO-219AB Sub SMA): Parts S1JL MHG, S1JL MQG, S1JL MTG, S1JL RFG, S1JL RHG, S1JL RQG, S1JL RTG, S1JL RUG, and S1JL RVG are direct parametric equivalents. These parts maintain identical electrical specifications including 600 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop, 1.8 µs reverse recovery time, and 5 µA reverse leakage current. All are packaged in DO-219AB Sub SMA form factor and are suitable for direct substitution in applications where the original package footprint is required.

Functional Equivalent (Alternative Package - SOD-123W): Part S1JLW is a manufacturer-recommended substitute with identical electrical performance (600 V, 1 A, 1.1 V forward voltage) but utilizes the SOD-123W package instead of Sub SMA. This part is selected when PCB layout or assembly process requirements necessitate an alternative surface mount package while maintaining full electrical compatibility.

Substitution eligibility is determined by the following key parameters: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Reverse Recovery Time (trr), Current - Reverse Leakage @ Vr, Operating Temperature range, and RoHS compliance status.

Engineering Selection Recommendations

All substitute parts listed are Active in product status and maintain full compliance with RoHS3 and REACH regulations, matching the certification profile of the primary S1JL part.

For applications requiring identical package footprint (DO-219AB Sub SMA): Select from parametric equivalents S1JL MHG, S1JL MQG, S1JL MTG, S1JL RFG, S1JL RHG, S1JL RQG, S1JL RTG, S1JL RUG, or S1JL RVG. These parts provide complete electrical equivalence with no design modifications required. Part S1JL RVG offers the highest inventory availability at 7700 pieces.

For applications permitting alternative surface mount packaging (SOD-123W): Select S1JLW as the manufacturer-recommended substitute. This part maintains identical voltage and current ratings with improved reverse leakage characteristics (1 µA versus 5 µA). The SOD-123W package is suitable for applications where PCB layout or automated assembly processes require a smaller or different footprint than Sub SMA.

For tape and reel packaging requirements: Parts S1JL RUG, S1JL RVG, and the primary S1JL are supplied in Tape & Reel (TR) format. Parametric equivalents without explicit TR designation may be available in alternative packaging formats.

Frequently Asked Questions (FAQ)

Q: Can S1JL be directly replaced with S1JL RVG?

A: Yes. S1JL RVG is a parametric equivalent with identical electrical specifications (600 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop, 1.8 µs reverse recovery time, 5 µA reverse leakage) and the same DO-219AB Sub SMA package. Direct substitution is applicable without circuit modifications.

Q: What is the difference between S1JL and S1JLW?

A: Both parts share identical voltage and current ratings (600 V, 1 A). The primary difference is packaging: S1JL uses DO-219AB Sub SMA, while S1JLW uses SOD-123W. Additionally, S1JLW exhibits lower reverse leakage current (1 µA versus 5 µA). Selection depends on PCB layout requirements and assembly process compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including S1JL MHG, S1JL MQG, S1JL MTG, S1JL RFG, S1JL RHG, S1JL RQG, S1JL RTG, S1JL RUG, S1JL RVG, and S1JLW, are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the primary S1JL part.

Q: Which substitute part has the best inventory availability?

A: S1JL RVG offers the highest inventory level at 7700 pieces in stock, followed by the primary S1JL at 20200 pieces. Both are available in Tape & Reel packaging.

Q: Can S1JL be used in applications requiring the SOD-123W package?

A: No. The S1JL is packaged in DO-219AB Sub SMA form factor and cannot be used in applications requiring SOD-123W package footprint. For SOD-123W applications, select S1JLW instead.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts, including S1JL and all listed equivalents, operate across the junction temperature range of -55°C to 175°C.

Q: Are the parametric equivalents (S1JL MHG, S1JL MQG, etc.) interchangeable?

A: Yes. All parametric equivalents maintain identical electrical specifications and DO-219AB Sub SMA packaging. Selection among these parts may be based on inventory availability or specific packaging format requirements (Tape & Reel versus alternative formats).
