SS19L M2G Schottky Diode Equivalent & Substitute Parts

Part Overview

The SS19L M2G 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).

The SS19L M2G serves applications requiring fast recovery Schottky diode performance in compact Sub SMA packaging. Identification of equivalent and substitute parts is necessary to support supply chain continuity, inventory optimization, and design flexibility when the primary part number becomes unavailable or when alternative packaging formats are required.

Substitute Part Grouping Explanation

Substitution of the SS19L M2G is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• 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 ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 50 µA @ 90 V
• Technology: Schottky

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-219AB
• Supplier Device Package: Sub SMA
• Operating Temperature - Junction: -55°C to 150°C

Compliance Equivalence Criteria:

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

The substitute part SS19L meets all electrical, mechanical, and compliance requirements for direct substitution. Packaging format variations (Cut Tape and Digi-Reel) do not affect electrical or functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The SS19L substitute part is electrically and mechanically equivalent to the SS19L M2G across all specified parameters. Both parts are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 and REACH requirements.

Product Status Consideration: The SS19L M2G maintains Active product status, while the SS19L substitute is designated as Not For New Designs. For new design implementations, the SS19L M2G is the appropriate selection. For existing designs or applications where supply continuity is the primary concern, the SS19L substitute provides full functional equivalence.

Packaging Format: The SS19L substitute is available in Cut Tape (CT) and Digi-Reel packaging formats, offering flexibility for different procurement and assembly workflows compared to the standard packaging of the main part.

Compliance: Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications subject to these standards.

Frequently Asked Questions (FAQ)

Q: Can the SS19L substitute be used directly in place of the SS19L M2G?

A: Yes. The SS19L substitute meets all electrical specifications (90 V reverse voltage, 1 A average rectified current, 800 mV forward voltage, fast recovery characteristics, and 50 µA reverse leakage), mechanical requirements (DO-219AB Sub SMA package, surface mount), and compliance certifications (ROHS3, REACH unaffected) of the SS19L M2G. Substitution is electrically and mechanically valid.

Q: What is the difference between the SS19L M2G and SS19L?

A: The primary differences are product status and packaging format. The SS19L M2G is designated Active product status, while the SS19L is Not For New Designs. The SS19L is available in Cut Tape and Digi-Reel packaging options. All electrical and mechanical parameters are identical.

Q: Are there any temperature or voltage derating considerations when substituting?

A: No. Both parts operate across the identical temperature range (-55°C to 150°C junction temperature) and are rated for the same maximum reverse voltage (90 V) and forward voltage characteristics (800 mV @ 1 A). No derating adjustments are required.

Q: Does the packaging format affect electrical performance?

A: No. Cut Tape, Digi-Reel, and standard packaging formats contain the same die and internal construction. Packaging format affects only procurement, handling, and assembly logistics, not electrical or thermal performance.

Q: Are both parts suitable for RoHS and REACH compliant applications?

A: Yes. Both the SS19L M2G and SS19L are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for applications subject to these standards.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life under normal storage conditions. No special moisture control measures are required during storage or handling.
