S1JL RFG Equivalent & Substitute Parts

Part Overview

The S1JL RFG 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 parametrically equivalent alternatives. The S1JL RFG maintains full electrical and mechanical compatibility with identified substitute part numbers that share identical electrical specifications and package configurations.

Substitute Part Grouping Explanation

Substitution of the S1JL RFG is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts S1JL and S1JLH are classified as parametric equivalents because they maintain identical specifications across the following key criteria:

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
• Operating Temperature - Junction: -55°C to 175°C

Compliance Parameters (Must Match Exactly):

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

All substitute parts share the same base product number (S1J) and technology classification (Standard). Substitution is valid only when all parameters listed above remain unchanged between the primary part and the selected substitute.

Engineering Selection Recommendations

Primary Part Selection: The S1JL RFG is the recommended selection for new designs. This part maintains Active product status, indicating full manufacturer support, ongoing production, and long-term availability. Active status ensures compliance with current manufacturing standards and supply chain reliability.

Substitute Part Selection: The S1JL and S1JLH substitute parts are classified as Not For New Designs. These parts are electrically and mechanically identical to the S1JL RFG and remain suitable for:

• Replacement in existing production runs
• Field service and repair applications
• Legacy system maintenance
• Inventory management when primary part availability is constrained

Both substitute parts maintain identical electrical performance, package configuration, and compliance certifications (RoHS3, REACH Unaffected). Selection between S1JL and S1JLH is determined by packaging requirements: S1JL is supplied in Tape & Reel (TR) format, as is S1JLH.

Compliance Verification: All parts in this equivalence group satisfy RoHS3 compliance and REACH unaffected status, confirming suitability for regulated applications and markets with environmental restrictions.

Frequently Asked Questions (FAQ)

Q: Can S1JL and S1JLH be used interchangeably with S1JL RFG in circuit designs?

A: Yes. S1JL and S1JLH are parametric equivalents 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) and identical mechanical packaging (DO-219AB Sub SMA surface mount). Direct substitution is valid from an electrical and mechanical standpoint.

Q: What is the difference between S1JL RFG, S1JL, and S1JLH?

A: The three part numbers are electrically and mechanically identical. The primary difference is product status: S1JL RFG is Active (recommended for new designs), while S1JL and S1JLH are Not For New Designs (suitable for replacement and legacy applications). All three share the same base product number (S1J) and are manufactured by Taiwan Semiconductor Corporation.

Q: Are there packaging differences between these substitute parts?

A: S1JL RFG is supplied in standard packaging format. S1JL and S1JLH are supplied in Tape & Reel (TR) format. All three use the identical DO-219AB package and Sub SMA supplier device package. Tape & Reel format is standard for high-volume surface mount assembly and does not affect electrical or mechanical compatibility.

Q: What does "Not For New Designs" status mean for S1JL and S1JLH?

A: Not For New Designs indicates that the manufacturer is not actively promoting these part numbers for new circuit designs. However, these parts remain fully functional and compliant. They are appropriate for replacement applications, field service, and existing production continuity where the part has already been qualified.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. S1JL RFG, S1JL, and S1JLH are all RoHS3 compliant and REACH unaffected. This compliance status is consistent across all three part numbers and confirms suitability for regulated markets and applications with environmental restrictions.

Q: What is the Moisture Sensitivity Level (MSL) for these diodes?

A: All three parts have MSL 1 (Unlimited), indicating unlimited shelf life without moisture control requirements. These diodes do not require special moisture-controlled storage or handling procedures.

Q: Can I use these diodes in high-temperature applications?

A: Yes. All three parts are rated for junction operating temperatures from -55°C to 175°C, supporting both industrial and high-temperature applications within this range.

Q: What is the reverse recovery time specification, and why is it important?

A: The reverse recovery time (trr) is 1.8 µs for all three parts. This parameter defines the time required for the diode to switch from forward conduction to reverse blocking. The 1.8 µs specification is consistent across all equivalents and determines switching performance in rectification circuits.
