Key Parameters

Substitute Part Grouping Explanation

Substitution of the LL4006G L0G is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 800 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A maximum
• Current - Reverse Leakage @ Vr: 5 µA @ 800 V maximum
• Speed: Standard Recovery >500ns, > 200mA (Io)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-213AB or equivalent MELF package

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The S1K diode from YAGEO meets these substitution requirements and is classified as an active product with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The S1K rectifier diode from YAGEO is a direct electrical substitute for the LL4006G L0G. Both components share identical voltage and current ratings, forward voltage characteristics, and compliance certifications. The S1K is currently in active production status with established supply chain availability, whereas the LL4006G L0G is obsolete.

Both components maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols. The S1K is supplied in Tape & Reel packaging format, suitable for automated assembly processes.

Selection of the S1K as a substitute is supported by electrical equivalence, active product status, and regulatory compliance alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the S1K replace the LL4006G L0G in existing designs?

A: Yes. The S1K meets all electrical specifications of the LL4006G L0G, including 800V reverse voltage rating, 1A average rectified current, and 1.1V forward voltage at 1A. Both components are Surface Mount rectifier diodes with identical functional characteristics.

Q: Are there package differences between these components?

A: The LL4006G L0G uses DO-213AB (MELF) packaging, while the S1K uses DO-214AC packaging. Both are surface mount packages with compatible footprint dimensions for standard PCB layouts. Verification of PCB pad geometry is recommended during design transition.

Q: Do both components meet the same compliance standards?

A: Yes. Both the LL4006G L0G and S1K are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Both components are classified as EAR99 for export control purposes.

Q: Why is the LL4006G L0G listed as obsolete?

A: The LL4006G L0G is an obsolete product from Taiwan Semiconductor Corporation. The S1K from YAGEO is an active alternative that provides equivalent electrical performance and is currently manufactured and stocked.

Q: What is the difference between DO-213AB and DO-214AC packages?

A: Both are surface mount rectifier packages. DO-213AB (MELF) and DO-214AC are industry-standard packages for 1A rectifier diodes. Physical dimensions and pad layouts differ slightly; PCB design files should be consulted to confirm compatibility with existing layouts.

Q: Are there inventory considerations for component selection?

A: The S1K is available in active production with established inventory levels. The LL4006G L0G, being obsolete, has limited remaining stock. For new designs and ongoing production, the S1K is the recommended selection based on availability and active manufacturer support.
