RS1AL MTG Equivalent & Substitute Parts

Part Overview

The RS1AL MTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 50 V DC reverse voltage and 800 mA average rectified current. This surface mount component features fast recovery characteristics with a reverse recovery time of 150 ns, making it suitable for standard rectification applications requiring Sub SMA packaging in DO-219AB form factor.

The RS1AL MTG is classified as an Active product. Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility is needed across different procurement channels while maintaining identical electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RS1AL MTG are determined by equivalence across all critical electrical parameters and mechanical compatibility. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match):

• 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 Parameters (Must Match):

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

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts may differ in packaging format (Tape & Reel, Cut Tape, or standard packaging) and product status classification, provided all electrical and mechanical specifications remain identical. These packaging variations accommodate different manufacturing and procurement workflows without affecting circuit performance.

Parameter Comparison

Engineering Selection Recommendations

RS1AL MTG (Primary Part): This part maintains Active product status and is the preferred selection for new designs. It provides full compliance with ROHS3 and REACH requirements with unlimited moisture sensitivity rating.

RS1AL: This part is electrically and mechanically identical to RS1AL MTG but carries a "Not For New Designs" classification. It is supplied in Tape & Reel packaging format. This part number is suitable for replacement applications, legacy system maintenance, or when Tape & Reel format is specifically required for automated assembly processes. Higher inventory availability (18,660 pcs) may support high-volume procurement needs.

RS1AL RVG: This part is electrically and mechanically identical to RS1AL MTG and maintains Active product status. It is supplied in Cut Tape packaging format. This part number is suitable for applications requiring Cut Tape format for manual assembly, prototyping, or lower-volume production runs. It provides an alternative sourcing option with Active status classification.

All three part numbers satisfy identical electrical performance requirements, compliance certifications, and thermal operating ranges. Selection between them is determined by packaging format requirements and manufacturing process compatibility rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RS1AL be used as a direct replacement for RS1AL MTG?

A: RS1AL is electrically and mechanically identical to RS1AL MTG. The primary difference is product status classification ("Not For New Designs" versus "Active") and packaging format (Tape & Reel versus standard). For replacement and maintenance applications, RS1AL provides full functional equivalence. For new design implementations, RS1AL MTG or RS1AL RVG are preferred due to Active status.

Q: What is the difference between the packaging formats offered?

A: RS1AL MTG is supplied in standard packaging format. RS1AL is supplied in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly equipment. RS1AL RVG is supplied in Cut Tape (CT) format, which is suitable for manual assembly, prototyping, and lower-volume applications. All three formats contain the identical diode component in DO-219AB package.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RS1AL MTG, RS1AL, and RS1AL RVG are all ROHS3 Compliant with REACH Unaffected status. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: Do the substitute parts have identical electrical performance?

A: Yes. All three part numbers have identical electrical specifications: 50 V reverse voltage rating, 800 mA average rectified current, 1.3 V forward voltage drop at 800 mA, 150 ns reverse recovery time, 5 µA reverse leakage current at 50 V, and 10 pF capacitance at 4V and 1 MHz. Operating temperature range is -55°C to 150°C for all variants.

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

A: RS1AL MTG or RS1AL RVG are both suitable for new designs, as both maintain Active product status. Selection between these two is based on packaging format requirements: RS1AL MTG for standard packaging or RS1AL RVG for Cut Tape format. RS1AL should not be used for new designs due to its "Not For New Designs" classification.

Q: What is the base product number for these parts?

A: The base product number for all three variants is RS1A. The suffixes (MTG, blank, RVG) indicate packaging format and configuration variations of the same core rectifier diode.
