Substitute Part Grouping Explanation

Substitution of the SS19L RTG is determined by strict equivalence across the following critical parameters:

• Voltage Rating: DC reverse voltage must equal 90 V maximum
• Current Rating: Average rectified current must equal 1 A
• Forward Voltage Drop: Maximum forward voltage must equal 800 mV at 1 A
• Recovery Speed: Fast recovery characteristic with recovery time ≤ 500 ns at currents > 200 mA
• Reverse Leakage: Maximum reverse leakage current must equal 50 µA at 90 V
• Package Type: DO-219AB (Sub SMA) surface mount package
• Technology: Schottky diode technology
• Temperature Range: Operating junction temperature range -55°C to 150°C
• Compliance: ROHS3 compliance and MSL 1 rating

The substitute part SS19L meets all specified electrical and mechanical parameters and is manufactured by the same supplier (Taiwan Semiconductor Corporation) using identical Schottky technology.

Parameter Comparison

Engineering Selection Recommendations

The SS19L substitute part is electrically and mechanically equivalent to the SS19L RTG across all specified parameters. Both components are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 requirements with MSL 1 rating.

The primary distinction between the two parts is product status: the SS19L RTG is classified as Active, while the SS19L substitute is classified as Not For New Designs. This status difference reflects supply chain and lifecycle management considerations rather than electrical or mechanical performance differences.

For applications requiring long-term supply assurance and design continuity, the Active status of SS19L RTG is the preferred selection. The substitute SS19L part is suitable for replacement in existing designs where component availability from current inventory is prioritized, provided that the Not For New Designs status aligns with project lifecycle requirements.

Both parts are suitable for direct substitution in circuit applications where the specified electrical parameters (90 V reverse voltage, 1 A current, 800 mV forward voltage drop, fast recovery ≤ 500 ns) and DO-219AB package are required.

Frequently Asked Questions (FAQ)

Q: Can SS19L be used as a direct replacement for SS19L RTG?

A: Yes. The SS19L meets all electrical and mechanical specifications of the SS19L RTG, including voltage rating (90 V), current rating (1 A), forward voltage drop (800 mV @ 1 A), recovery speed (≤ 500 ns), reverse leakage (50 µA @ 90 V), package type (DO-219AB), and operating temperature range (-55°C to 150°C). Both components are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between SS19L RTG and SS19L?

A: The electrical and mechanical specifications are identical. The difference is product status: SS19L RTG is Active, while SS19L is classified as Not For New Designs. This reflects lifecycle management and supply chain strategy rather than performance differences.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the DO-219AB (Sub SMA) surface mount package and are mounted using identical surface mount assembly processes.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: DC reverse voltage (90 V), average rectified current (1 A), forward voltage drop (800 mV @ 1 A), recovery speed (≤ 500 ns), reverse leakage current (50 µA @ 90 V), package type (DO-219AB), technology (Schottky), and operating temperature range (-55°C to 150°C).

Q: Can these parts be used in high-frequency switching applications?

A: Yes. Both parts feature fast recovery characteristics (≤ 500 ns at currents > 200 mA), which is suitable for high-frequency switching applications within the specified voltage and current ratings.

Q: Are there compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.
