Substitute Part Grouping Explanation

Substitution of the ES1DLH is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 950 mV @ 1 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Equivalence Requirements:

• Mounting Type: Surface Mount
• Package Category: SOD-123 family

Compliance Requirements:

• RoHS3 Compliant
• REACH Unaffected

The ES1DLWH meets all electrical equivalence criteria and maintains RoHS3 and REACH compliance. The primary difference is the package variant (SOD-123W versus SOD-123) and enhanced operating temperature range, which represents a functional improvement rather than a limitation.

Engineering Selection Recommendations

ES1DLWH as Primary Substitute:

The ES1DLWH is the manufacturer-recommended equivalent for the ES1DLH. This substitution is supported by:

1. Electrical Equivalence: All critical electrical parameters are identical, including reverse voltage rating (200V), average rectified current (1A), forward voltage drop (950mV @ 1A), and reverse recovery time (35ns).

2. Product Status: The ES1DLWH carries "Active" product status, ensuring continued availability and manufacturer support, whereas the ES1DLH is designated "Not For New Designs."

3. Compliance Certification: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

4. Enhanced Operating Range: The ES1DLWH extends the maximum junction operating temperature to 175°C compared to the ES1DLH's 150°C, providing improved thermal margin in high-temperature environments.

5. Package Consideration: The ES1DLWH uses the SOD-123W package variant, which is mechanically compatible with SOD-123 footprints in standard surface mount applications. PCB layout verification is required to confirm package dimensions align with existing design specifications.

Frequently Asked Questions (FAQ)

Q: Can ES1DLWH be used as a direct replacement for ES1DLH in existing designs?

A: Yes. The ES1DLWH meets all electrical equivalence criteria for the ES1DLH. Both parts share identical voltage ratings (200V), current ratings (1A), forward voltage characteristics (950mV @ 1A), and reverse recovery time (35ns). The primary consideration is package footprint compatibility between SOD-123 and SOD-123W variants on the PCB.

Q: What is the difference between SOD-123 and SOD-123W packages?

A: Both are surface mount diode packages in the SOD-123 family. The SOD-123W designation indicates a wider package variant. Physical dimensions differ, requiring verification that the ES1DLWH footprint aligns with existing PCB layouts designed for ES1DLH. Consult manufacturer datasheets for precise dimensional specifications.

Q: Are there any electrical performance differences between ES1DLH and ES1DLWH?

A: No electrical performance differences exist for the specified parameters. Both parts deliver identical reverse voltage (200V), forward current (1A), forward voltage drop (950mV @ 1A), and reverse recovery time (35ns). The ES1DLWH provides an extended operating temperature range (-55°C to 175°C versus -55°C to 150°C), which represents an improvement.

Q: Why is ES1DLH marked "Not For New Designs"?

A: This designation indicates the manufacturer has transitioned this part to end-of-life status and recommends using active alternatives for new product development. The ES1DLWH is the active equivalent in the manufacturer's current product portfolio.

Q: Do both parts meet automotive qualification standards?

A: The ES1DLH carries AEC-Q101 automotive qualification. The ES1DLWH datasheet provided does not specify AEC-Q101 qualification status. Verify automotive qualification requirements with the manufacturer if this certification is mandatory for the application.

Q: What compliance certifications apply to both parts?

A: Both ES1DLH and ES1DLWH are ROHS3 compliant and REACH unaffected, satisfying environmental and hazardous substance regulations for electronic components in regulated markets.
