SS19LHRVG Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS19LHRVG 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 an active product and carries automotive-grade qualification under AEC-Q101 standards. The part is packaged in DO-219AB (Sub SMA) configuration for surface mount applications.

Identification of equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when design flexibility is required within the same electrical and mechanical specifications. The SS19LHRVG maintains full compatibility with designated substitute parts that share identical electrical ratings and package specifications.

Substitute Part Grouping Explanation

Substitution of the SS19LHRVG is determined by strict equivalence across all critical electrical and mechanical parameters. A valid substitute part must satisfy the following criteria:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 90 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 800 mV @ 1 A
• Speed - Fast Recovery: ≤ 500 ns, > 200 mA (Io)
• Current - Reverse Leakage @ Vr: 50 µA @ 90 V
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Technology: Schottky

Compliance Parameters (Must Match or Exceed):

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

The SS19L meets all substitution criteria and is identified as a parametric equivalent to the SS19LHRVG. Both parts share identical electrical ratings, package specifications, and compliance certifications. The primary distinction is product status: SS19LHRVG is active, while SS19L is designated as Not For New Designs.

Engineering Selection Recommendations

For Active Designs: The SS19LHRVG is the recommended selection for new circuit designs. This part carries active product status and maintains full automotive-grade qualification under AEC-Q101 standards. All electrical and mechanical parameters are current and supported by the manufacturer.

For Existing Designs or Supply Continuity: The SS19L serves as a direct parametric equivalent when supply of the SS19LHRVG is constrained or unavailable. Both parts are electrically and mechanically identical and share identical compliance certifications (ROHS3, REACH Unaffected, MSL 1). The SS19L is designated as Not For New Designs, indicating it is maintained for legacy applications and existing production runs only.

Compliance Considerations: Both the SS19LHRVG and SS19L satisfy automotive-grade requirements and carry AEC-Q101 qualification. Both parts are ROHS3 compliant and REACH unaffected, making them suitable for applications subject to environmental and regulatory compliance requirements.

Packaging and Handling: Both parts are supplied in DO-219AB (Sub SMA) surface mount package with MSL 1 (Unlimited) moisture sensitivity rating. No special moisture control measures are required during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can SS19L be used as a direct replacement for SS19LHRVG in existing circuit designs?

A: Yes. The SS19L is electrically and mechanically identical to the SS19LHRVG. Both parts share the same 90 V reverse voltage rating, 1 A average rectified current, 800 mV forward voltage drop, fast recovery speed, and DO-219AB package specification. No circuit modifications are required for substitution.

Q: What is the difference between SS19LHRVG and SS19L?

A: The primary difference is product status. SS19LHRVG is classified as Active, while SS19L is classified as Not For New Designs. All electrical specifications, mechanical dimensions, and compliance certifications are identical between the two parts.

Q: Are both parts suitable for automotive applications?

A: Yes. Both SS19LHRVG and SS19L carry automotive-grade qualification under AEC-Q101 standards. Both parts are ROHS3 compliant and REACH unaffected, meeting automotive industry compliance requirements.

Q: What does "Not For New Designs" mean for the SS19L?

A: This designation indicates that SS19L is maintained by the manufacturer for legacy applications and existing production runs. For new circuit designs, the SS19LHRVG (Active status) is the recommended selection. However, SS19L remains fully functional and compliant for use in existing designs requiring component replacement or supply continuity.

Q: Are there any differences in packaging or handling between these parts?

A: No. Both parts are supplied in DO-219AB (Sub SMA) surface mount package with identical MSL 1 (Unlimited) moisture sensitivity rating. Handling, storage, and assembly procedures are identical for both parts.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts are mechanically and electrically identical with the same DO-219AB package footprint. They can be used interchangeably on the same printed circuit board assembly without any design or layout modifications.

Q: What is the operating temperature range for both parts?

A: Both SS19LHRVG and SS19L operate across a junction temperature range of -55°C to 150°C, providing full coverage for industrial and automotive temperature environments.
