Parametric Equivalent Parts maintain all critical electrical specifications and package requirements. These parts are direct functional replacements with identical performance characteristics. Vishay ES3D series variants (ES3D-E3/57T, ES3D-E3/9AT, ES3D-M3/57T, ES3D-M3/9AT, ES3DHE3_A/H, ES3DHE3_A/I, ES3DHE3J_A/I, ES3DHM3_A/H, ES3DHM3_A/I) differ only in packaging format (Cut Tape, Digi-Reel, or Tape & Reel) and product status (Active vs. Obsolete). Automotive-grade variants (ES3DHE3_A/H, ES3DHE3_A/I, ES3DHE3J_A/I, ES3DHM3_A/H, ES3DHM3_A/I) include AEC-Q101 qualification.

Upgrade Part (UFS320JE3/TR13 from Microchip Technology) meets all critical electrical parameters with a forward voltage specification of 950 mV @ 3 A (compared to 900 mV for the ES3D/7T) and extends the maximum junction temperature to 175°C. This represents a performance upgrade suitable for higher-temperature applications.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

Select from the active Vishay ES3D series parametric equivalents: ES3D-E3/57T, ES3D-E3/9AT, ES3D-M3/57T, or ES3D-M3/9AT. These parts maintain 100% electrical equivalence to the ES3D/7T with identical forward voltage (900 mV @ 3 A), reverse recovery time (30 ns), and reverse leakage current (10 µA @ 200 V). All are RoHS3 compliant and available in active production status. Selection among these variants depends on packaging format requirements: Cut Tape & Digi-Reel (E3 variants) or Tape & Reel (M3 variants).

For Automotive Applications:

If the application requires automotive-grade components with AEC-Q101 qualification, select ES3DHE3_A/H, ES3DHE3_A/I, ES3DHE3J_A/I, ES3DHM3_A/H, or ES3DHM3_A/I. These maintain identical electrical specifications while meeting automotive qualification standards. All are RoHS3 compliant and in active production.

For Extended Temperature Operation:

The UFS320JE3/TR13 from Microchip Technology extends the maximum junction temperature to 175°C (compared to 150°C for ES3D variants). This part is suitable for applications requiring higher thermal headroom. Forward voltage is specified at 950 mV @ 3 A, representing a 50 mV increase over the ES3D/7T. This part is RoHS3 compliant and in active production.

Compliance Considerations:

The ES3D/7T is RoHS non-compliant. All recommended substitutes are RoHS3 compliant, meeting current regulatory requirements. All parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can ES3D-E3/57T be used as a direct replacement for ES3D/7T?

A: Yes. ES3D-E3/57T is a parametric equivalent with identical electrical specifications: 200 V reverse voltage, 3 A average rectified current, 900 mV forward voltage @ 3 A, and 30 ns reverse recovery time. The primary difference is product status (Active vs. Obsolete) and packaging format (Cut Tape & Digi-Reel vs. unspecified for ES3D/7T). Both use DO-214AB surface mount packages.

Q: What is the difference between ES3D-E3/57T and ES3D-M3/57T?

A: Both parts are parametric equivalents with identical electrical specifications. The difference is packaging format: ES3D-E3/57T is supplied in Cut Tape & Digi-Reel format, while ES3D-M3/57T is supplied in Tape & Reel format. Selection depends on assembly line requirements and inventory management preferences.

Q: Are automotive-grade ES3DHE3 and ES3DHM3 variants suitable for non-automotive applications?

A: Yes. Automotive-grade variants (ES3DHE3_A/H, ES3DHE3_A/I, ES3DHE3J_A/I, ES3DHM3_A/H, ES3DHM3_A/I) maintain identical electrical specifications to standard-grade variants and include AEC-Q101 qualification. These parts can be used in any application where the ES3D/7T was previously used. Automotive qualification does not restrict use in non-automotive circuits.

Q: Can UFS320JE3/TR13 replace ES3D/7T without circuit modification?

A: UFS320JE3/TR13 is electrically compatible with ES3D/7T for the critical parameters: 200 V reverse voltage, 3 A average rectified current, 30 ns reverse recovery time, and DO-214AB package. However, forward voltage is specified at 950 mV @ 3 A compared to 900 mV for ES3D/7T. This 50 mV difference may affect power dissipation and thermal performance in current-limited applications. Verify that circuit design accommodates this forward voltage specification before substitution.

Q: Why is the ES3D/7T classified as obsolete?

A: The ES3D/7T is no longer in active production. Multiple active alternatives with identical or superior electrical characteristics are available from Vishay (ES3D series variants) and other manufacturers (Microchip UFS320JE3/TR13). Obsolete classification indicates end-of-life status; new designs should specify active alternatives.

Q: Are all substitute parts RoHS compliant?

A: Yes. All recommended substitute parts are RoHS3 compliant. The original ES3D/7T is RoHS non-compliant. Substitution with any recommended alternative improves regulatory compliance for new production and design updates.

Q: What is the inventory status of substitute parts?

A: Active Vishay variants have varying inventory levels: ES3D-E3/57T (79,415 pcs), ES3D-E3/9AT (110,400 pcs), ES3D-M3/57T (2,000 pcs), ES3D-M3/9AT (735 pcs), ES3DHE3_A/H (1,665 pcs), ES3DHE3_A/I (55,100 pcs), ES3DHE3J_A/I (1,014 pcs), ES3DHM3_A/H (913 pcs), ES3DHM3_A/I (827 pcs). Microchip UFS320JE3/TR13 has 894 pcs in stock. Inventory levels should be verified with suppliers for current availability.

Q: Can ES3D/7T be used interchangeably with parts from the substitute list in existing designs?

A: Yes, for designs currently using ES3D/7T. All parametric equivalents maintain identical electrical performance. For new designs, specify active alternatives (ES3D-E3/57T, ES3D-E3/9AT, ES3D-M3/57T, ES3D-M3/9AT, or automotive variants) to ensure long-term supply chain continuity and regulatory compliance.
