RS1MLSHRVG Equivalent & Substitute Parts

Part Overview

The RS1MLSHRVG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 1000 V DC reverse voltage and 1.2 A average rectified current in a surface mount SOD-123HE package. This component is classified as Active and suitable for new designs. The diode exhibits fast recovery characteristics with a reverse recovery time of 300 ns, making it applicable in switching power supplies, converter circuits, and general rectification applications requiring high voltage and moderate current handling.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within the same functional category.

Substitute Part Grouping Explanation

Substitution of the RS1MLSHRVG is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1.2 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1.2 A
• Reverse Recovery Time (trr): 300 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: SOD-123H
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C

The RS1MFP manufactured by onsemi meets all specified electrical parameters and mechanical requirements. Both components share identical base product number RS1M, confirming functional equivalence within the rectifier diode category.

Engineering Selection Recommendations

RS1MLSHRVG (Primary Selection): The RS1MLSHRVG is the recommended component for new designs. It carries Active product status, indicating full manufacturer support and continued availability. The component is ROHS3 compliant, REACH unaffected, and carries MSL 1 rating for unlimited moisture exposure tolerance. Manufacturing is by Taiwan Semiconductor Corporation with 1123 pieces currently in stock.

RS1MFP (Alternative Selection): The RS1MFP is electrically and mechanically equivalent to the RS1MLSHRVG across all critical parameters. However, this component is designated as Not For New Designs by onsemi. The RS1MFP carries Automotive grade qualification with AEC-Q101 certification, indicating suitability for automotive applications where such qualification is required. The RS1MFP maintains ROHS3 compliance and REACH unaffected status. Current inventory is 7914 pieces.

Selection between these components depends on design requirements: choose RS1MLSHRVG for standard applications and new designs; select RS1MFP only when automotive-grade qualification and AEC-Q101 certification are mandatory requirements, acknowledging the Not For New Designs status.

Frequently Asked Questions (FAQ)

Q: Can RS1MFP be used as a direct replacement for RS1MLSHRVG in existing designs?

A: Yes. Both components share identical electrical specifications (1000 V reverse voltage, 1.2 A average rectified current, 1.3 V forward voltage, 300 ns reverse recovery time, 5 µA reverse leakage) and are packaged in the same SOD-123HE surface mount package. Mechanical and electrical compatibility is confirmed.

Q: What is the difference between the RS1MLSHRVG and RS1MFP?

A: The primary differences are manufacturer (Taiwan Semiconductor Corporation versus onsemi), product status (Active versus Not For New Designs), and qualification level (Standard versus Automotive with AEC-Q101). All electrical and mechanical parameters are identical.

Q: Why is RS1MFP marked as Not For New Designs?

A: This designation is assigned by the manufacturer onsemi and indicates that the component is in mature or end-of-life status. New designs should prioritize RS1MLSHRVG. The RS1MFP remains available for existing production and legacy system support.

Q: Does the Automotive grade of RS1MFP affect compatibility?

A: No. Automotive grade indicates enhanced qualification and testing per AEC-Q101 standards. This is a superset of standard qualification and does not create incompatibility. The RS1MFP can be used in non-automotive applications without functional impact.

Q: Are there any thermal or performance differences between these diodes?

A: No. Both components operate across the identical temperature range (-55°C to 150°C junction temperature) and exhibit identical reverse recovery time (300 ns) and leakage characteristics (5 µA @ 1000 V).

Q: What is the significance of the SOD-123HE package designation?

A: SOD-123HE is the supplier device package specification for both components. This ensures identical PCB footprint, solder pad layout, and surface mount assembly compatibility. Both diodes are interchangeable at the board level.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both RS1MLSHRVG and RS1MFP are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. Both components can be stored and handled without moisture bake-out requirements prior to soldering, simplifying supply chain and assembly logistics.
