Key Parameters

Substitute Part Grouping Explanation

The TBU-PL060-100-WH qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Series: TBU® (same product family)
• Technology: Internal Switch (identical protection mechanism)
• Number of Circuits: 2 (same circuit configuration)
• Applications: SLIC (same functional application)
• Mounting Type: Surface Mount (identical assembly method)
• Package / Case: SMD 6.50mm x 4.00mm (identical physical dimensions)
• Supplier Device Package: SMD (same package type)
• RoHS Status: ROHS3 Compliant (equivalent compliance)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical handling requirements)

Differentiation Parameters:

• Voltage - Clamping: 600V (substitute) vs. 500V (original)
• Voltage - Working: 350V (substitute) vs. 300V (original)
• Product Status: Active (substitute) vs. Obsolete (original)

The substitute part maintains identical mechanical compatibility and circuit configuration while providing enhanced voltage ratings, making it suitable for applications requiring the original part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The TBU-PL060-100-WH is the designated substitute for the obsolete TBU-PL050-100-WH. Selection of this substitute is supported by:

• Product Status Alignment: The substitute maintains active production status, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements.
• Mechanical Compatibility: Identical package dimensions (SMD 6.50mm x 4.00mm) and mounting type enable direct PCB-level replacement without layout modifications.
• Functional Equivalence: Matching circuit configuration (2 circuits), technology (internal switch), and application focus (SLIC) preserve circuit protection functionality.
• Enhanced Specifications: The substitute provides higher voltage ratings (600V clamping, 350V working) compared to the original (500V clamping, 300V working), offering improved protection margins within the same physical footprint.

Frequently Asked Questions (FAQ)

Q: Can the TBU-PL060-100-WH be used as a direct replacement for the TBU-PL050-100-WH?

A: Yes. Both parts share identical mechanical dimensions, mounting type, circuit configuration, and package specifications. The substitute maintains full compatibility at the PCB assembly level.

Q: What are the key differences between these parts?

A: The primary differences are voltage ratings and product status. The TBU-PL060-100-WH provides higher clamping voltage (600V vs. 500V) and working voltage (350V vs. 300V), while maintaining active production status compared to the obsolete original.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, ECCN classification (EAR99), and HTSUS codes.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the package dimensions identical?

A: Yes. Both parts use the same SMD package with dimensions of 6.50mm x 4.00mm, enabling direct PCB-level substitution without layout changes.
