LC03-6R2G Equivalent & Substitute Parts

Part Overview

The LC03-6R2G is an active Transient Voltage Suppressor (TVS) diode manufactured by onsemi, designed for steering rail-to-rail protection in surface mount applications. This 8-SOIC package device provides 5V reverse standoff voltage with 20V clamping capability and 100A peak pulse current handling. The part is actively produced and widely stocked, with 23,920 units available in inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to supply constraints, design flexibility, or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LC03-6R2G are qualified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Criteria:

• Voltage - Reverse Standoff: 5V to 6V range (allows minor tolerance variation)
• Voltage - Breakdown (Min): 6.8V (fixed requirement)
• Voltage - Clamping (Max) @ Ipp: 20V (fixed requirement)
• Current - Peak Pulse (10/1000µs): 100A minimum (8/20µs pulse)
• Power - Peak Pulse: 2000W minimum

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: 8-SOIC or 8-SO (compatible footprints)
• Unidirectional Channels: 2
• Type: Steering (Rail to Rail)

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

Substitute parts meeting these criteria are classified as direct or similar equivalents based on parameter alignment with the main part specification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the LC03-6R2G.

SP03-6BTG (Littelfuse Inc.): This part exceeds the minimum current specification with 150A peak pulse capability and 2.8kW power dissipation, providing enhanced margin for transient protection. Operating temperature range is -40°C to 125°C, which is narrower than the main part. This substitute is suitable for applications where higher current handling is beneficial and the reduced temperature range is acceptable.

CDNBS08-PLC03-6 (Bourns Inc.): This part matches the electrical specifications of the main part with 100A peak pulse current and 2000W power dissipation. Operating temperature range extends to -55°C to 150°C, matching the main part's lower temperature limit. This substitute provides direct functional equivalence with identical thermal performance.

LC03-6.TBT (Semtech Corporation): This part matches the electrical specifications with 100A peak pulse current and 2000W power dissipation. Operating temperature range is -55°C to 125°C. The package designation is listed as 8-SO rather than 8-SOIC, though both are mechanically compatible 8-pin surface mount packages with identical 0.154" width. This substitute provides functional equivalence with minor package variant notation.

Frequently Asked Questions (FAQ)

Q: Can SP03-6BTG replace LC03-6R2G in all applications?

A: SP03-6BTG is electrically compatible with higher current capability (150A vs. 100A). The primary consideration is the operating temperature range: SP03-6BTG operates from -40°C to 125°C, while LC03-6R2G operates from -55°C to 150°C. Substitution is valid only if the application temperature range falls within -40°C to 125°C.

Q: What is the difference between 8-SOIC and 8-SO packages?

A: Both 8-SOIC and 8-SO are 8-pin surface mount packages with identical 0.154" (3.90mm) width and compatible PCB footprints. The designations reflect minor manufacturing variations but are mechanically and electrically interchangeable for this application.

Q: Are all substitute parts pin-compatible with LC03-6R2G?

A: Yes. All substitute parts are Steering (Rail to Rail) TVS diodes with 2 unidirectional channels in 8-pin surface mount packages. Pin configuration and functional assignment are identical across all listed parts.

Q: Which substitute part provides the best thermal performance?

A: CDNBS08-PLC03-6 and LC03-6R2G both support the full operating temperature range of -55°C to 150°C. SP03-6BTG and LC03-6.TBT have upper temperature limits of 125°C, making them suitable for applications with lower maximum operating temperatures.

Q: Can I use these parts interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical package dimensions (8-SOIC, 0.154" width), mounting type (Surface Mount), and electrical specifications within the defined parameter ranges. PCB layout and assembly processes require no modification.

Q: What is the voltage standoff difference between the main part and substitutes?

A: LC03-6R2G has a 5V typical reverse standoff voltage, while all substitute parts have 6V standoff voltage. Both values fall within the acceptable range for steering TVS diodes and do not affect functional compatibility in typical protection circuits.
