SS19LHRTG Equivalent & Substitute Parts

Part Overview

The SS19LHRTG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component is rated for 90 V DC reverse voltage with 1 A average rectified current and features fast recovery characteristics suitable for high-frequency switching applications. The part carries Active product status and meets AEC-Q101 automotive qualification standards.

The SS19L represents a parametric equivalent alternative to the SS19LHRTG. While functionally identical in electrical performance, the SS19L carries a Not For New Designs product status, making it suitable for legacy system support and maintenance applications rather than new product development initiatives.

Substitute Part Grouping Explanation

Substitution of the SS19LHRTG with the SS19L is based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical performance parameters:

Key Substitution Parameters:

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

Both parts conform to ROHS3 compliance, carry Moisture Sensitivity Level 1 (Unlimited), and maintain REACH Unaffected status. The substitution is valid where electrical performance and thermal operating range requirements are identical.

Engineering Selection Recommendations

For New Product Development: The SS19LHRTG is the appropriate selection for new designs. This part carries Active product status and meets AEC-Q101 automotive qualification requirements, ensuring long-term availability and manufacturing support.

For Legacy System Support and Maintenance: The SS19L is suitable for replacement and repair applications in existing systems where the component has been previously qualified. The Not For New Designs status indicates this part is maintained for legacy support only and should not be selected for new product development initiatives.

Compliance Considerations: Both parts maintain identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). Selection between these parts should be driven by product development phase and long-term supply chain requirements rather than compliance or electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can SS19L be used as a direct replacement for SS19LHRTG in new designs?

A: No. While the SS19L is electrically and mechanically equivalent, it carries Not For New Designs product status. New product development must use the SS19LHRTG, which has Active status and ensures ongoing manufacturer support.

Q: Are the electrical specifications identical between SS19LHRTG and SS19L?

A: Yes. Both parts share identical specifications for voltage rating (90 V), current rating (1 A), forward voltage (800 mV @ 1 A), recovery speed (≤ 500ns), reverse leakage current (50 µA @ 90 V), and operating temperature range (-55°C to 150°C).

Q: Do both parts use the same package?

A: Yes. Both SS19LHRTG and SS19L use the DO-219AB package in Sub SMA format with surface mount mounting type. PCB layout and assembly processes are identical.

Q: What is the difference in packaging options between these parts?

A: The SS19LHRTG is supplied in standard packaging. The SS19L is available in Cut Tape (CT) and Digi-Reel® packaging formats, which may affect ordering quantities and handling procedures.

Q: Are there compliance or certification differences?

A: No. Both parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). The SS19LHRTG additionally carries AEC-Q101 automotive qualification.

Q: When should SS19L be selected over SS19LHRTG?

A: The SS19L should be selected only for maintenance and repair of existing systems where this part number has been previously qualified and is in active use. For all new applications, the SS19LHRTG is the correct selection.
