RS1MLS RVG Equivalent & Substitute Parts

Part Overview

The RS1MLS RVG 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 product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary manufacturer part is unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits selection from qualified equivalent devices that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS1MLS RVG is permissible with parts that maintain identical electrical performance across all critical parameters: reverse voltage rating (1000 V), average rectified current (1.2 A), forward voltage drop (1.3 V @ 1.2 A), reverse recovery time (300 ns), reverse leakage current (5 µA @ 1000 V), and fast recovery speed classification (≤ 500ns, > 200mA).

Mechanical compatibility requires identical package designation (SOD-123H) and supplier device package (SOD-123HE) to ensure proper PCB footprint alignment and automated assembly compatibility.

Compliance requirements include RoHS3 compliance and MSL 1 rating to maintain environmental and moisture handling standards.

The RS1MFP manufactured by onsemi qualifies as a parametric equivalent substitute, meeting all electrical and mechanical specifications. However, product status differences and automotive qualification grades must be evaluated within the context of specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The RS1MLS RVG maintains Active product status, indicating ongoing manufacturer support and availability for new design implementations. This status provides assurance of continued supply and technical support.

The RS1MFP substitute part carries "Not For New Designs" status, which indicates the manufacturer has discontinued active promotion of this device for new applications. While the part remains electrically and mechanically equivalent, this status reflects manufacturer lifecycle decisions and may signal reduced long-term availability or support.

The RS1MFP includes automotive-grade qualification (AEC-Q101) and automotive classification, which represents enhanced reliability screening and qualification beyond standard industrial requirements. This additional qualification is present in the substitute but not specified for the main part.

For applications requiring long-term supply assurance and ongoing manufacturer support, the RS1MLS RVG is the preferred selection. For applications where automotive-grade qualification provides additional value and where the "Not For New Designs" status does not conflict with project lifecycle requirements, the RS1MFP remains electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can RS1MFP be used as a direct replacement for RS1MLS RVG in existing designs?

A: Yes. The RS1MFP meets all 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 mechanical requirements (SOD-123HE package, surface mount). Both parts are RoHS3 compliant with MSL 1 rating.

Q: What does "Not For New Designs" status mean for the RS1MFP?

A: This status indicates the manufacturer (onsemi) has classified this part as end-of-life for new design implementations. Existing inventory may be available, but the manufacturer does not recommend this part for new projects. The RS1MLS RVG, with Active status, is the recommended choice for new designs.

Q: Are there package compatibility concerns when substituting between these parts?

A: No. Both parts use identical package designation (SOD-123H) and supplier device package (SOD-123HE), ensuring identical PCB footprint compatibility and automated assembly compatibility.

Q: Does the automotive qualification of RS1MFP affect its use in non-automotive applications?

A: No. Automotive qualification (AEC-Q101) represents additional reliability screening and does not restrict use in non-automotive applications. The automotive-grade part meets or exceeds standard industrial requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are RoHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. No compliance or regulatory barriers exist to substitution.

Q: What is the reverse recovery time specification and why is it important?

A: Reverse recovery time (trr) is 300 ns for both parts. This parameter defines the time required for the diode to transition from forward conduction to reverse blocking state. Identical specifications ensure equivalent switching performance in rectification and protection circuits.
