S1JL RQG Equivalent & Substitute Parts

Part Overview

The S1JL RQG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 600 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package (DO-219AB). This component is classified as Active product status and is RoHS3 compliant.

Substitute parts become necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when design requirements permit selection from equivalent alternatives that maintain identical electrical and mechanical specifications. The S1JL RQG maintains full parametric equivalence with designated substitute part numbers S1JL and S1JLH, which share identical electrical characteristics and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1JL RQG is determined by strict parametric matching across all critical electrical and mechanical specifications. The following parameters establish substitution validity:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 600 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 @ 600 V
• Capacitance @ Vr, F: 9 pF @ 4V, 1MHz

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Supplier Device Package: Sub SMA

Environmental & Compliance Parameters (Must Match Exactly):

• Operating Temperature - Junction: -55°C to 175°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts S1JL and S1JLH meet all substitution criteria and are classified as parametric equivalents to S1JL RQG.

Engineering Selection Recommendations

S1JL RQG (Primary Selection): The S1JL RQG is the recommended selection for new designs. This part maintains Active product status, indicating full manufacturer support and continued availability. It is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

S1JL (Secondary Selection): The S1JL is a parametric equivalent substitute with identical electrical and mechanical specifications. However, this part is designated as Not For New Designs. Selection of S1JL is appropriate for legacy system maintenance, field replacements, or applications where design revision is not feasible. This part is available in Tape & Reel packaging with substantial inventory (20,200 pcs).

S1JLH (Secondary Selection): The S1JLH is a parametric equivalent substitute with identical electrical and mechanical specifications. This part is designated as Not For New Designs. Selection of S1JLH is appropriate for legacy system maintenance, field replacements, or applications where design revision is not feasible. This part is available in Tape & Reel packaging with substantial inventory (19,224 pcs).

Packaging Consideration: The S1JL RQG is supplied in standard packaging configuration. Substitute parts S1JL and S1JLH are supplied in Tape & Reel (TR) packaging. Both packaging formats are compatible with automated assembly processes and maintain identical component specifications.

Frequently Asked Questions (FAQ)

Q: Can S1JL and S1JLH be used interchangeably with S1JL RQG?

A: Yes. S1JL and S1JLH are parametric equivalents with identical electrical characteristics (600 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop, 1.8 µs reverse recovery time) and mechanical specifications (DO-219AB package, Sub SMA surface mount). All three parts operate across the same temperature range (-55°C to 175°C) and maintain identical compliance certifications (RoHS3, REACH unaffected).

Q: What is the difference between S1JL RQG and the substitute parts?

A: The primary difference is product status. S1JL RQG maintains Active status for new designs. S1JL and S1JLH are designated Not For New Designs, indicating they are available for legacy applications and field replacements but should not be selected for new product development. All three parts are electrically and mechanically identical.

Q: Are there packaging differences between these parts?

A: S1JL RQG is supplied in standard packaging. S1JL and S1JLH are supplied in Tape & Reel (TR) format. Both packaging configurations are suitable for automated surface mount assembly and do not affect component performance or compatibility.

Q: Can these diodes be used in high-temperature applications?

A: Yes. All three parts (S1JL RQG, S1JL, and S1JLH) are rated for junction temperatures from -55°C to 175°C, supporting operation in elevated temperature environments within this specified range.

Q: Are all three parts RoHS compliant?

A: Yes. S1JL RQG, S1JL, and S1JLH are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the reverse leakage current specification?

A: All three parts maintain a maximum reverse leakage current of 5 µA at 600 V reverse voltage, ensuring consistent performance in rectification applications.

Q: Is there a difference in reverse recovery time between these parts?

A: No. All three parts (S1JL RQG, S1JL, and S1JLH) have identical reverse recovery time of 1.8 µs, classified as Standard Recovery with >500 ns recovery at >200 mA average rectified current.
