Substitute Part Grouping Explanation

Substitute parts for the ES1D-LS are grouped based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Parameters for Substitution:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 1 A
Package / Case: DO-214AC, SMA
Mounting Type: Surface Mount
Operating Temperature Range: -55°C ~ 150°C
Technology: Standard

Substitute parts maintain identical or superior electrical characteristics within the specified parameter ranges. Parts are classified as parametric equivalents when all critical electrical parameters match the original specification. Variations in secondary parameters such as capacitance or reverse recovery time within acceptable tolerances do not preclude substitution compatibility.

Engineering Selection Recommendations

Primary Recommendation: ES1D-13-F (Diodes Incorporated)

The ES1D-13-F is the direct parametric equivalent to the ES1D-LS, manufactured by the same supplier. This part maintains identical electrical specifications including forward voltage, reverse recovery time, and capacitance. The ES1D-13-F is active in production with substantial inventory availability (550,400 pcs), ensuring long-term supply continuity. Both parts are ROHS3 compliant and REACH unaffected.

Secondary Recommendations: Vishay General Semiconductor - Diodes Division Series

The ES1D-E3/5AT, ES1D-E3/61T, ES1D-M3/5AT, and ES1D-M3/61T variants from Vishay maintain identical critical electrical parameters (200 V, 1 A, 920 mV forward voltage, 25 ns recovery time). These parts differ in packaging configuration (Cut Tape & Digi-Reel versus Tape & Reel) and inventory levels. All are active products with ROHS3 compliance and REACH unaffected status.

Automotive-Grade Options: ES1DHE3_A/H, ES1DHE3_A/I, ES1DHM3_A/H, ES1DHM3_A/I

These Vishay variants are qualified to AEC-Q101 automotive standards and maintain identical electrical specifications. Selection of automotive-grade parts is appropriate for applications requiring automotive qualification or enhanced reliability assurance.

Alternative Manufacturer: ES1D (EVVO Semi)

The EVVO Semi ES1D provides parametric equivalence with minor variations in forward voltage (1 V versus 920 mV) and reverse recovery time (35 ns versus 25 ns). This part is active with 140,400 pcs inventory. Selection of this alternative is appropriate when forward voltage and recovery time variations are acceptable within circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can ES1D-13-F directly replace ES1D-LS without circuit modification?

A: Yes. The ES1D-13-F is a parametric equivalent with identical electrical specifications and package configuration. Direct substitution is supported without circuit design changes.

Q: What is the difference between Diodes Incorporated ES1D-13-F and Vishay ES1D-E3/61T?

A: Both parts meet the critical electrical specifications (200 V, 1 A, 920 mV forward voltage, 25 ns recovery time). The primary differences are manufacturer, packaging configuration, and inventory availability. Vishay parts feature lower capacitance (10 pF versus 20 pF), which may provide advantages in high-frequency applications.

Q: Are the automotive-grade variants (ES1DHE3_A/H, ES1DHM3_A/H) suitable for non-automotive applications?

A: Yes. Automotive-grade parts meet or exceed standard commercial specifications and are fully compatible with non-automotive circuit applications. Selection of automotive-grade variants provides enhanced reliability assurance without performance penalty.

Q: What is the significance of the packaging designations (5AT, 61T, M3, E3)?

A: These designations indicate packaging configuration and tape format. The 5AT and 61T suffixes denote different tape reel specifications. The M3 and E3 prefixes indicate manufacturing variants. All variants maintain identical electrical performance and mechanical compatibility within the DO-214AC, SMA package.

Q: Can EVVO Semi ES1D be used as a substitute despite higher forward voltage (1 V)?

A: The EVVO Semi ES1D is a parametric equivalent with acceptable variations in forward voltage (1 V versus 920 mV) and reverse recovery time (35 ns versus 25 ns). Substitution is appropriate when circuit design margins accommodate these parameter variations. Forward voltage differences of 80 mV are typically acceptable in rectifier applications.

Q: What is the MSL (Moisture Sensitivity Level) rating for substitute parts?

A: All active substitute parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture control requirements. The obsolete ES1D-LS does not specify MSL rating.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
