DF202ST-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF202ST-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for 200 V peak reverse voltage applications with 2 A average rectified current capacity. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The DF202ST-G operates across a wide temperature range of -55°C to 150°C and is packaged in a 4-SMD Gull Wing surface mount configuration. Locating functionally equivalent active alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF202ST-G is determined by strict equivalence across the following critical parameters:

• Diode Type & Technology: Single Phase, Standard technology
• Voltage Rating: 200 V peak reverse voltage (Vr)
• Current Rating: 2 A average rectified current (Io)
• Forward Voltage Characteristics: 1.1 V maximum at 2 A
• Reverse Leakage: 10 µA at 200 V
• Temperature Range: -55°C to 150°C junction temperature
• Package Configuration: 4-SMD Gull Wing surface mount
• Compliance: ROHS3 compliant, MSL Level 1

The DF202S-G meets all these criteria and is manufactured by the same supplier (Comchip Technology), ensuring electrical and mechanical compatibility with the obsolete DF202ST-G.

Parameter Comparison

Engineering Selection Recommendations

The DF202S-G is the direct active equivalent for the obsolete DF202ST-G. Both components share identical electrical specifications, mechanical packaging, and regulatory compliance certifications. The DF202S-G is currently in active production status with confirmed inventory availability (1067 pcs), whereas the DF202ST-G is obsolete. For new designs and replacement applications, the DF202S-G provides full functional equivalence with the advantage of ongoing manufacturer support and supply chain continuity. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the DF202S-G directly replace the DF202ST-G in existing designs?

A: Yes. The DF202S-G is electrically and mechanically identical to the DF202ST-G across all specified parameters, including voltage rating, current capacity, forward voltage characteristics, temperature range, and 4-SMD Gull Wing package configuration.

Q: What is the primary reason for substitution?

A: The DF202ST-G is classified as obsolete. The DF202S-G is the active equivalent manufactured by Comchip Technology and is currently in production with available inventory.

Q: Are there any packaging differences between these parts?

A: The DF202ST-G packaging is listed as unspecified in the original documentation. The DF202S-G is supplied in Tube packaging. Both use identical 4-SMD Gull Wing surface mount configuration. Verify packaging requirements for your specific application workflow.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DF202ST-G and DF202S-G are ROHS3 compliant, REACH unaffected, with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What are the critical electrical parameters for substitution?

A: Substitution is valid when the following parameters match: 200 V peak reverse voltage, 2 A average rectified current, 1.1 V forward voltage at 2 A, 10 µA reverse leakage at 200 V, and -55°C to 150°C operating temperature range.
