KBP201G C2G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBP201G C2G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 50 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Bridge rectifiers in this category are used in AC-to-DC conversion applications requiring through-hole mounting and standard rectification technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP201G C2G is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: KBP form factor
• Current - Average Rectified (Io): 2 A (exact match required)
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Allowable Variation:

• Voltage - Peak Reverse (Max): The substitute may exceed the original 50 V rating, provided the application does not require voltage derating
• Voltage - Forward (Vf): Minor variations are acceptable within standard rectifier performance tolerances
• Current - Reverse Leakage: Lower leakage values indicate improved performance characteristics

The KBP201G manufactured by SMC Diode Solutions meets these criteria as a direct substitute, with the exception of elevated peak reverse voltage (100 V versus 50 V), which represents an enhancement rather than a limitation for most applications.

Parameter Comparison

Engineering Selection Recommendations

The KBP201G manufactured by SMC Diode Solutions is a direct functional substitute for the obsolete KBP201G C2G from Taiwan Semiconductor Corporation. Selection of this substitute is supported by the following factors:

Product Status: The SMC Diode Solutions variant is classified as Active, ensuring continued availability and manufacturing support, whereas the original part is Obsolete.

Compliance & Certifications: Both components maintain ROHS3 compliance and identical moisture sensitivity ratings (MSL 1 - Unlimited), ensuring compatibility with current manufacturing and environmental standards.

Electrical Performance: The substitute demonstrates equivalent or superior electrical characteristics, including identical current rating (2 A), identical operating temperature range (-55°C ~ 150°C), lower forward voltage drop (1.1 V versus 1.2 V @ 2 A), and lower reverse leakage current (5 µA versus 10 µA).

Voltage Rating: The substitute's 100 V peak reverse voltage rating exceeds the original 50 V specification. This elevated rating is compatible with applications designed for the original 50 V component and introduces no functional limitations.

Packaging: Both components utilize the KBP through-hole form factor with identical mounting characteristics, ensuring direct mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the KBP201G from SMC Diode Solutions be used as a direct replacement for the obsolete KBP201G C2G?

A: Yes. Both components share identical current ratings (2 A), operating temperature ranges (-55°C ~ 150°C), mounting types (through-hole), and package form factors (KBP). The SMC variant is electrically compatible and currently in active production.

Q: What is the significance of the higher voltage rating (100 V) on the substitute part?

A: The substitute's 100 V peak reverse voltage rating is a performance enhancement relative to the original 50 V specification. Applications designed for 50 V operation remain fully compatible with the 100 V-rated substitute, as the component will not be exposed to voltages exceeding its design limits.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both components are ROHS3 compliant, maintain identical moisture sensitivity levels (MSL 1 - Unlimited), and carry equivalent environmental certifications. No additional qualification is required from a regulatory standpoint.

Q: How do the forward voltage drop characteristics compare?

A: The SMC Diode Solutions KBP201G exhibits a lower forward voltage drop (1.1 V @ 2 A) compared to the Taiwan Semiconductor KBP201G C2G (1.2 V @ 2 A). This represents improved efficiency and reduced power dissipation in the substitute component.

Q: Will the substitute part fit the existing PCB layout?

A: Yes. Both components utilize through-hole mounting in the KBP package form factor. The 4-ESIP variant used by SMC Diode Solutions maintains mechanical compatibility with the original 4-SIP, KBP package, ensuring direct PCB compatibility without layout modifications.

Q: What is the inventory status of the substitute part?

A: The KBP201G from SMC Diode Solutions is currently in active production with 1270 pieces available in new original stock condition, packaged in tube format.
