SS19L RVG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS19L RVG is a surface mount Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 90 V DC reverse voltage and 1 A average rectified current. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Identification of equivalent and substitute parts becomes necessary when the primary part number is unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Specifications:

• Voltage - DC Reverse (Vr) (Max): 90 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 800 mV @ 1 A
• Current - Reverse Leakage @ Vr: 50 µA @ 90 V
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Environmental Specifications:

• Mounting Type: Surface Mount
• Package / Case: DO-219AB (Sub SMA)
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky

Compliance & Regulatory:

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

Substitute parts must match all electrical parameters, maintain identical package specifications, and satisfy all regulatory compliance requirements. Product status differences do not affect electrical or mechanical substitutability.

Parameter Comparison

Engineering Selection Recommendations

The SS19L manufactured by Taiwan Semiconductor Corporation is the parametric equivalent to the SS19L RVG. Both parts are manufactured by the same supplier and share identical electrical, mechanical, and thermal specifications.

The primary distinction between these parts is product status: the SS19L RVG maintains Active status, while the SS19L substitute is designated as Not For New Designs. This status difference reflects lifecycle positioning and does not affect electrical performance, compliance certifications, or functional compatibility.

Selection between these parts should be based on:

1. Availability and Inventory: The SS19L substitute maintains higher inventory levels (7,600 Pcs) compared to the SS19L RVG (721 Pcs), making it suitable for high-volume applications where supply continuity is critical.

2. Regulatory Compliance: Both parts satisfy ROHS3 compliance and REACH unaffected status, permitting use in regulated markets without additional qualification.

3. Packaging Format: The SS19L substitute is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for automated assembly processes.

4. Long-Term Sourcing: For new designs requiring extended product lifecycle support, the SS19L RVG (Active status) is the preferred selection. For applications with defined production windows or where inventory availability is the primary constraint, the SS19L substitute provides equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the SS19L substitute be used in place of the SS19L RVG in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (90 V reverse voltage, 1 A average rectified current, 800 mV forward voltage drop), identical thermal operating range (-55°C to 150°C), and identical package specifications (DO-219AB Sub SMA). Functional substitution is direct without circuit modification.

Q: What is the significance of the "Not For New Designs" status on the SS19L substitute?

A: Product status indicates lifecycle positioning within the manufacturer's portfolio. "Not For New Designs" status does not imply functional deficiency or compliance issues. It reflects the manufacturer's recommendation to prioritize the Active status part (SS19L RVG) for new product development. Existing designs and high-volume production runs may continue using the substitute without performance degradation.

Q: Are there packaging differences between the SS19L RVG and SS19L substitute?

A: Both parts use identical package specifications (DO-219AB, Sub SMA). The SS19L substitute is available in Cut Tape (CT) and Digi-Reel® formats, which are standard packaging options for automated assembly. The SS19L RVG packaging format is not specified in the provided data. Packaging format selection should align with assembly process requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the SS19L RVG and SS19L substitute are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL 1 - Unlimited). No additional compliance qualification is required when substituting between these parts.

Q: What are the key electrical parameters that define substitutability for this diode?

A: Substitutability is determined by matching: (1) Voltage - DC Reverse (Vr) at 90 V maximum, (2) Current - Average Rectified (Io) at 1 A, (3) Voltage - Forward (Vf) at 800 mV maximum at 1 A forward current, (4) Speed classification as Fast Recovery ≤ 500ns for currents > 200mA, and (5) Current - Reverse Leakage at 50 µA maximum at 90 V reverse bias. All substitute parts must match these specifications exactly.

Q: Is the operating temperature range identical between the main part and substitute?

A: Yes. Both parts operate across the junction temperature range of -55°C to 150°C, ensuring thermal compatibility in all specified application environments.
