Substitute Part Grouping Explanation

Substitute parts for the RS1AL RTG are determined by electrical parameter equivalence and mechanical compatibility. All identified substitutes maintain identical electrical specifications across the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 50 V
• Current - Average Rectified (Io): 800 mA
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 800 mA
• Reverse Recovery Time (trr): 150 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 50 V
• Capacitance @ Vr, F: 10 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 150°C
• Package / Case: DO-219AB (Sub SMA)
• Mounting Type: Surface Mount
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Substitutes differ only in packaging format (Tape & Reel or Cut Tape) and product status classification. All substitutes are manufactured by Taiwan Semiconductor Corporation and maintain full compliance with RoHS3, REACH, and MSL requirements.

Engineering Selection Recommendations

RS1AL RTG (Primary Selection)

The RS1AL RTG is the recommended selection for new designs. This part maintains Active product status, ensuring continued manufacturer support and long-term availability. It is suitable for applications requiring standard packaging formats and provides full compliance with RoHS3 and REACH regulations.

RS1AL RVG (Alternative Selection)

The RS1AL RVG is electrically and mechanically equivalent to the RS1AL RTG and maintains Active product status. This part is supplied in Cut Tape (CT) packaging format, making it suitable for applications where smaller quantity procurement or tape-based assembly processes are required. Selection of this part does not compromise electrical performance or regulatory compliance.

RS1AL (Legacy Selection)

The RS1AL is electrically and mechanically equivalent to the RS1AL RTG but is classified as Not For New Designs. This part is supplied in Tape & Reel (TR) packaging format. Use of this part is limited to replacement, repair, or continuation of existing production runs where design continuity is required. This part is not suitable for new design implementations.

Frequently Asked Questions (FAQ)

Q: Are all three parts electrically interchangeable?

A: Yes. The RS1AL RTG, RS1AL, and RS1AL RVG are electrically identical. All three parts share identical specifications for voltage rating (50 V), current rating (800 mA), forward voltage drop (1.3 V @ 800 mA), reverse recovery time (150 ns), and all other electrical parameters. They are functionally interchangeable in circuit applications.

Q: What is the difference between these parts?

A: The three parts differ in packaging format and product status. The RS1AL RTG and RS1AL RVG are both Active products; the RS1AL is classified as Not For New Designs. The RS1AL RTG uses standard packaging, the RS1AL RVG uses Cut Tape (CT) format, and the RS1AL uses Tape & Reel (TR) format. These differences affect procurement, handling, and assembly processes but do not affect electrical performance.

Q: Can I use RS1AL in a new design?

A: No. The RS1AL is classified as Not For New Designs. For new design implementations, use either the RS1AL RTG or RS1AL RVG. Both parts maintain Active product status and provide equivalent electrical performance.

Q: What packaging format should I select?

A: Packaging format selection depends on assembly process requirements and procurement volume. The RS1AL RTG uses standard packaging suitable for general applications. The RS1AL RVG uses Cut Tape (CT) format, appropriate for lower-volume or manual assembly processes. The RS1AL uses Tape & Reel (TR) format, suitable for high-volume automated assembly. All three formats are compatible with the DO-219AB package and Sub SMA supplier device package specification.

Q: Are there any compliance or regulatory differences?

A: No. All three parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). There are no regulatory or compliance differences between the parts.

Q: Can I substitute these parts on an existing PCB assembly?

A: Yes. All three parts use the DO-219AB package with Sub SMA supplier device package specification and Surface Mount mounting type. They are mechanically and electrically compatible for direct substitution on existing PCB assemblies.

Q: What is the operating temperature range?

A: All three parts operate across a junction temperature range of -55°C to 150°C. This range is identical across all substitute parts.
