DF201-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF201-G is a single-phase bridge rectifier diode manufactured by Comchip Technology, rated for 100 V peak reverse voltage and 2 A average rectified current. This component is actively produced and suitable for new designs. Bridge rectifiers are essential in power supply circuits for converting AC to DC voltage. Substitute parts may be required due to supply constraints, design revisions, or application-specific requirements where electrical parameters remain compatible.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF201-G bridge rectifier is determined by the following critical parameters:

• Voltage - Peak Reverse (Max): Must equal or exceed 100 V
• Current - Average Rectified (Io): Must equal or exceed 2 A for direct replacement
• Voltage - Forward (Vf): Must not exceed 1.1 V @ rated current
• Current - Reverse Leakage: Must not exceed 10 µA @ 100 V
• Operating Temperature Range: Must support -55°C ~ 150°C minimum
• Mounting Type: Through Hole required
• Package Compatibility: 4-EDIP form factor with compatible pin spacing

The identified substitute parts DB102-BP and DF01M meet the voltage and leakage specifications but have reduced current ratings (1 A vs. 2 A). These substitutes are suitable only for applications where the circuit current requirement does not exceed 1 A.

Parameter Comparison

Engineering Selection Recommendations

The DF201-G remains the primary choice for new designs due to its Active product status and 2 A current rating. DB102-BP is not recommended for new designs as indicated by its product status classification. DF01M is an active alternative with equivalent voltage and leakage specifications; however, its 1 A current rating limits its use to applications requiring ≤1 A average rectified current. All three parts maintain ROHS3 compliance and equivalent thermal performance within their respective current ratings. Package dimensions vary slightly between DF01M (0.300") and the other two parts (0.321"), which may affect PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can DB102-BP directly replace DF201-G in all applications? A: No. DB102-BP has a maximum average rectified current of 1 A compared to DF201-G's 2 A rating. Substitution is valid only for circuits drawing ≤1 A. Additionally, DB102-BP is classified as Not For New Designs.

Q: What is the primary difference between DF201-G and DF01M? A: Both parts share identical voltage (100 V), forward voltage (1.1 V), and leakage specifications. The key difference is current rating: DF201-G supports 2 A while DF01M supports 1 A. DF01M also has a slightly smaller package dimension (0.300" vs. 0.321").

Q: Are all substitute parts RoHS compliant? A: DF201-G and DB102-BP are explicitly ROHS3 compliant. DF01M's RoHS status is not specified in the provided data.

Q: Can DF01M be used in place of DF201-G if the circuit only requires 1 A? A: Yes, provided the application does not exceed 1 A average rectified current and the slightly smaller package dimension (0.300" vs. 0.321") is compatible with the PCB layout.

Q: What determines whether a bridge rectifier can substitute for DF201-G? A: The substitute must meet or exceed the voltage rating (100 V), support the required current level, maintain equivalent forward voltage and leakage characteristics, operate within the temperature range, and use compatible through-hole packaging.
