Substitute Part Grouping Explanation

Substitute parts for the KBU402G T0 are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Parameters:

• Voltage - Peak Reverse (Max): 100 V
• Current - Average Rectified (Io): 4 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 4 A
• Current - Reverse Leakage @ Vr: 5 µA @ 100 V
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: 4-SIP, KBU

Compliance Parameters:

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

Parts matching all specified electrical, mechanical, and compliance parameters are classified as direct substitutes and are electrically and mechanically interchangeable with the KBU402G T0.

Parameter Comparison

Engineering Selection Recommendations

The KBU402G (without the T0 suffix) is a direct substitute for the KBU402G T0. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications, mechanical packaging, and compliance certifications.

The primary distinction is product status: the KBU402G T0 is discontinued at DiGi Electronics, while the KBU402G maintains active status with current inventory availability (1084 Pcs New Original In Stock). Both parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

For applications currently specified with KBU402G T0, the KBU402G provides equivalent performance and is suitable for direct replacement in through-hole PCB designs requiring single-phase bridge rectification at 100 V and 4 A ratings.

Frequently Asked Questions (FAQ)

Q: Can the KBU402G be used as a direct replacement for the KBU402G T0?

A: Yes. Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical parameters (100 V peak reverse voltage, 4 A average rectified current, 1.1 V forward voltage, 5 µA reverse leakage), operating temperature range (-55°C to 150°C), mechanical packaging (4-SIP KBU through-hole), and compliance certifications (ROHS3, MSL 1). The parts are electrically and mechanically interchangeable.

Q: What does the T0 suffix indicate on the KBU402G T0?

A: The T0 suffix is a manufacturer designation that does not affect electrical or mechanical specifications. The base part number KBU402G defines the electrical and physical characteristics. The KBU402G without the T0 suffix is functionally equivalent.

Q: Are there any package or pinout differences between KBU402G T0 and KBU402G?

A: No. Both parts use the 4-SIP KBU package format for through-hole mounting. Pinout and mechanical dimensions are identical, allowing direct PCB substitution without layout modifications.

Q: What is the significance of the ROHS3 compliance rating?

A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, hexavalent chromium, and specified brominated flame retardants. Both the KBU402G T0 and KBU402G are ROHS3 compliant, suitable for applications with environmental and regulatory compliance requirements.

Q: Why is the KBU402G T0 discontinued while the KBU402G remains active?

A: Product discontinuation decisions are based on manufacturer supply chain management and market demand. The KBU402G represents the current active production variant. Both parts maintain identical specifications, making the KBU402G the recommended source for new procurement.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why is it important?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to soldering. This simplifies inventory management and assembly processes for through-hole components.
