RS201-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The RS201-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 50 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The RS-2 package configuration and standard rectification technology define the functional scope for direct substitution.

Key Parameters

Substitute Part Grouping Explanation

The KBP2005G-G qualifies as a direct substitute for the RS201-G based on the following critical parameters:

• Identical voltage rating: 50 V peak reverse voltage
• Identical current rating: 2 A average rectified current
• Identical forward voltage characteristic: 1.1 V @ 2 A
• Identical reverse leakage specification: 10 µA @ 50 V
• Identical diode type and technology: Single Phase Standard
• Compatible mounting: Through Hole configuration
• Identical moisture sensitivity level: MSL 1 (Unlimited)

The KBP2005G-G maintains all electrical performance parameters within the specified operating range, enabling direct functional replacement in circuit applications designed for the RS201-G.

Parameter Comparison

Engineering Selection Recommendations

The KBP2005G-G is the qualified substitute for the obsolete RS201-G. Both components are manufactured by Comchip Technology and share identical electrical specifications across all critical parameters: voltage rating, current capacity, forward voltage drop, and reverse leakage characteristics.

The KBP2005G-G offers additional advantages: active product status ensures ongoing availability and supply chain continuity, extended operating temperature range (-55°C to 150°C versus -55°C to 125°C), and ROHS3 compliance certification. These attributes make the KBP2005G-G suitable for new designs and legacy system replacements.

Both parts maintain MSL 1 rating and REACH unaffected status, confirming compatibility with standard handling and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the KBP2005G-G replace the RS201-G in existing circuits?

A: Yes. The KBP2005G-G matches all electrical parameters of the RS201-G: 50 V peak reverse voltage, 2 A average rectified current, 1.1 V forward voltage drop, and 10 µA reverse leakage. Through-hole mounting compatibility confirms direct board-level substitution.

Q: What is the difference between the RS-2 and KBP package designations?

A: Both are 4-SIP through-hole packages. The RS-2 designation applies to the obsolete RS201-G, while KBP designates the active KBP2005G-G. Package footprints are compatible for direct replacement.

Q: Why does the KBP2005G-G have a higher maximum operating temperature?

A: The KBP2005G-G extends the upper temperature limit to 150°C (versus 125°C for RS201-G). This represents an engineering improvement in the active product line and does not affect substitution compatibility for applications operating within the original -55°C to 125°C range.

Q: Is the KBP2005G-G RoHS compliant?

A: Yes. The KBP2005G-G carries ROHS3 compliance certification. RoHS status for the obsolete RS201-G is not specified in available documentation.

Q: Are there inventory considerations for this substitution?

A: The KBP2005G-G is an active product with confirmed stock availability (1096 pcs), whereas the RS201-G is obsolete. Transition to the KBP2005G-G ensures long-term supply security.
