ES2DPX Equivalent & Substitute Parts

Part Overview

The ES2DPX is a general-purpose rectifier diode manufactured by Nexperia USA Inc., rated for 200 V DC reverse voltage and 2 A average rectified current in a surface mount SOD-128/CFP5 package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The fast recovery characteristics and compact surface mount packaging make this diode suitable for standard rectification applications requiring moderate voltage and current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ES2DPX is based on electrical and mechanical parameter equivalence within the following criteria:

Electrical Equivalence Requirements:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 25 ns maximum
• Operating Temperature - Junction (Max): 150°C minimum

Mechanical Equivalence Requirements:

• Mounting Type: Surface Mount
• Package / Case: SOD-128 compatible footprint
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

The RF202LAM2STFTR from Rohm Semiconductor meets all specified electrical and mechanical parameters while maintaining active product status and automotive-grade qualification (AEC-Q101). This part is suitable for direct substitution in applications where the ES2DPX was previously specified.

Parameter Comparison

Engineering Selection Recommendations

The RF202LAM2STFTR is the qualified substitute for the obsolete ES2DPX based on the following engineering criteria:

Electrical Performance: Both parts maintain identical voltage and current ratings (200 V, 2 A) with equivalent fast recovery characteristics and reverse recovery time specifications. The RF202LAM2STFTR exhibits a marginally lower forward voltage drop (930 mV versus 950 mV at 2 A), which represents improved efficiency with no negative impact on circuit operation.

Product Status and Availability: The ES2DPX is classified as obsolete, whereas the RF202LAM2STFTR maintains active product status with confirmed inventory availability (3300 pcs in stock). This transition ensures long-term supply chain continuity for new production and design revisions.

Compliance and Qualification: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. The RF202LAM2STFTR carries AEC-Q101 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

Package Compatibility: Both parts utilize the SOD-128 surface mount package with identical footprint and land pattern requirements, enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the RF202LAM2STFTR be used as a direct replacement for the ES2DPX without circuit modifications?

A: Yes. The RF202LAM2STFTR is electrically and mechanically equivalent to the ES2DPX across all critical parameters: voltage rating, current rating, reverse recovery time, and package footprint. No circuit modifications are required for substitution.

Q: What is the significance of the lower forward voltage drop in the RF202LAM2STFTR?

A: The RF202LAM2STFTR exhibits a forward voltage drop of 930 mV at 2 A compared to 950 mV for the ES2DPX. This 20 mV difference represents improved efficiency and reduced power dissipation in the diode, resulting in lower junction temperatures during operation. This is a beneficial characteristic with no adverse effects on circuit compatibility.

Q: Are there package differences between the ES2DPX and RF202LAM2STFTR?

A: Both parts use the SOD-128 package. The ES2DPX is supplied in SOD-128/CFP5 configuration, while the RF202LAM2STFTR is supplied in PMDTM configuration. Both packages maintain identical SOD-128 footprints and are interchangeable on PCB layouts without modification.

Q: What is the difference between the reverse leakage current specifications?

A: The ES2DPX specifies 200 nA reverse leakage at 200 V, while the RF202LAM2STFTR specifies 10 µA at 200 V. The RF202LAM2STFTR exhibits higher reverse leakage current. This parameter difference does not affect substitution suitability for standard rectification applications where reverse leakage is not a critical design constraint.

Q: Does the AEC-Q101 qualification of the RF202LAM2STFTR affect its use in non-automotive applications?

A: No. AEC-Q101 qualification indicates that the RF202LAM2STFTR meets automotive reliability standards and is suitable for use in automotive applications. This qualification does not restrict use in non-automotive applications and represents an additional quality assurance benefit.

Q: What is the moisture sensitivity level (MSL) rating, and why is it important?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements prior to soldering. This simplifies component handling and storage procedures for manufacturing operations.

Q: Are both parts RoHS compliant?

A: Yes. Both the ES2DPX and RF202LAM2STFTR are ROHS3 compliant, meeting European Union Restriction of Hazardous Substances regulations. Both parts are suitable for applications requiring RoHS compliance.
