RS1AL RUG Equivalent & Substitute Parts

Part Overview

The RS1AL RUG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component operates at 50 V DC reverse voltage with an average rectified current rating of 800 mA, featuring fast recovery characteristics suitable for standard switching applications.

The RS1AL RUG maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating. Alternative part numbers within this family are available due to packaging format variations and inventory distribution across different supplier configurations. Substitute parts maintain identical electrical performance while offering different packaging and delivery formats.

Substitute Part Grouping Explanation

Substitution eligibility for the RS1AL RUG is determined by electrical parameter equivalence across the following critical specifications:

Electrical Equivalence Criteria:

• 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

Mechanical Compatibility Criteria:

• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Supplier Device Package: Sub SMA

All substitute parts listed maintain identical electrical characteristics and mechanical compatibility. Variations exist only in packaging format (Tape & Reel or Cut Tape) and product status designations, which do not affect functional performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

RS1AL RUG (Primary Part): Maintains Active product status and is suitable for new design implementations. This part number is the recommended selection for applications requiring standard packaging in tube format.

RS1AL: Designated as Not For New Designs. This part number is electrically and mechanically equivalent but should be used only for legacy system maintenance, repair, or replacement applications where existing designs already specify this part number. The Tape & Reel packaging format provides bulk distribution capability.

RS1AL RVG: Maintains Active product status and provides electrical and mechanical equivalence with Cut Tape packaging format. This part number is suitable for new designs requiring individual component delivery or automated pick-and-place assembly processes.

All three part numbers comply with ROHS3 and REACH requirements, carry unlimited moisture sensitivity rating, and operate across the identical temperature range. Selection between these equivalents should be based on packaging format requirements and assembly process compatibility rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can RS1AL RUG be directly replaced with RS1AL or RS1AL RVG in existing circuit designs?

A: Yes. All three part numbers are electrically and mechanically equivalent. They share identical voltage ratings (50 V), current ratings (800 mA), forward voltage characteristics (1.3 V @ 800 mA), reverse recovery time (150 ns), and operating temperature range (-55°C to 150°C). The DO-219AB package and Sub SMA supplier device package are consistent across all variants. Substitution is valid from a functional standpoint.

Q: What is the difference between RS1AL RUG, RS1AL, and RS1AL RVG?

A: The primary differences are packaging format and product status. RS1AL RUG uses tube packaging and maintains Active status. RS1AL uses Tape & Reel packaging but is designated Not For New Designs. RS1AL RVG uses Cut Tape packaging and maintains Active status. All three contain identical diode components with matching electrical specifications.

Q: Which part number should be selected for new product designs?

A: Either RS1AL RUG or RS1AL RVG are appropriate for new designs, as both maintain Active product status. Selection between these two should be based on assembly process requirements. RS1AL RUG suits manual or tube-fed assembly processes, while RS1AL RVG is optimized for automated pick-and-place assembly using cut tape format.

Q: Are there any compliance or certification differences between these part numbers?

A: No. All three part numbers carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). Regulatory and environmental compliance is equivalent across all variants.

Q: Can RS1AL be used in new designs despite its Not For New Designs designation?

A: RS1AL is electrically and mechanically equivalent to RS1AL RUG and RS1AL RVG. However, the Not For New Designs designation indicates this part number is in legacy status. For new product development, RS1AL RUG or RS1AL RVG are the recommended selections to ensure long-term availability and manufacturer support.

Q: What packaging format is most suitable for high-volume automated assembly?

A: RS1AL RVG with Cut Tape packaging is optimized for automated pick-and-place assembly processes. This format provides individual component spacing suitable for high-speed assembly equipment.

Q: Are the reverse recovery time and leakage current specifications identical across all three part numbers?

A: Yes. Reverse recovery time is 150 ns and reverse leakage current is 5 µA @ 50 V across RS1AL RUG, RS1AL, and RS1AL RVG. These critical switching characteristics are identical, ensuring equivalent performance in fast recovery rectifier applications.
