S1JL RTG Equivalent & Substitute Parts

Part Overview

The S1JL RTG 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 S1JL RTG reaches end-of-life inventory constraints, when specific packaging formats (Tape & Reel) are required for automated assembly processes, or when alternative product variants with identical electrical performance are needed to maintain supply chain flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S1JL RTG is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• 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
• Operating Temperature - Junction: -55°C to 175°C
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Technology: Standard

Packaging format variations (bulk versus Tape & Reel) do not affect electrical substitutability. Both identified substitute parts—S1JL and S1JLH—maintain identical electrical specifications and thermal performance characteristics, differing only in packaging presentation and product status designation.

Engineering Selection Recommendations

S1JL RTG (Primary Selection)

The S1JL RTG maintains Active product status, indicating ongoing manufacturer support and availability. This part is the preferred selection for new designs and applications requiring long-term supply assurance. Current inventory of 649 pieces supports immediate procurement requirements.

S1JL (Tape & Reel Format)

The S1JL substitute part is electrically identical to the S1JL RTG but is supplied in Tape & Reel packaging format. This variant is designated as Not For New Designs, indicating it is maintained for legacy system support and existing production lines. The Tape & Reel format is suitable for automated pick-and-place assembly operations. Inventory availability of 20,200 pieces provides extended supply capacity for high-volume production environments.

S1JLH (Tape & Reel Format)

The S1JLH substitute part maintains identical electrical and thermal specifications to the S1JL RTG and is also supplied in Tape & Reel packaging. This variant carries Not For New Designs status. Inventory of 19,224 pieces supports sustained production requirements. Selection between S1JL and S1JLH Tape & Reel variants depends on existing supply chain agreements and assembly line compatibility.

All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity classification, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

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

A: Yes. All three parts maintain identical electrical specifications across voltage rating, current capacity, forward voltage drop, reverse recovery time, reverse leakage current, and junction temperature range. Direct substitution is electrically valid without circuit modification.

Q: What is the difference between S1JL RTG and the S1JL Tape & Reel variant?

A: The primary difference is packaging format. S1JL RTG is supplied in bulk packaging, while S1JL is supplied in Tape & Reel format optimized for automated assembly. Electrical performance is identical. The Tape & Reel format reduces manual handling and integrates directly with pick-and-place equipment.

Q: Why are S1JL and S1JLH marked as "Not For New Designs"?

A: This designation indicates these variants are maintained for legacy system support and existing production continuity rather than for new product development. The S1JL RTG, marked as Active, is the recommended selection for new circuit designs.

Q: Are there any thermal or reliability differences between these substitute parts?

A: No. All three parts share identical operating temperature range (-55°C to 175°C junction temperature), reverse recovery time (1.8 µs), and reverse leakage characteristics (5 µA @ 600 V). Thermal and reliability performance are equivalent.

Q: Which packaging format should be selected for high-volume automated assembly?

A: Tape & Reel format (S1JL or S1JLH) is standard for automated pick-and-place assembly operations. Bulk packaging (S1JL RTG) is suitable for manual assembly or lower-volume applications.

Q: Do all three parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH Unaffected, and classified as MSL Level 1 (Unlimited). Compliance certifications are identical across all three variants.

Q: What inventory considerations apply when selecting between these parts?

A: S1JL RTG has 649 pieces in stock (Active status). S1JL has 20,200 pieces available (Tape & Reel format). S1JLH has 19,224 pieces available (Tape & Reel format). Selection should account for immediate availability needs and production volume requirements.
