FR204GP-AP General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The FR204GP-AP is an active general purpose rectifier diode manufactured by Micro Commercial Co, rated for 400 V DC reverse voltage and 2 A average rectified current in a through-hole DO-15 package. This component is classified as a fast recovery diode with a reverse recovery time of 150 ns, suitable for standard rectification applications requiring moderate switching speeds.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter range. Alternative sources and package configurations may be required due to inventory availability, supply chain considerations, or specific application mounting requirements.

Substitute Part Grouping Explanation

Substitution of the FR204GP-AP is determined by equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.3 V or lower at 2 A
• Current - Reverse Leakage @ Vr: 5 µA or lower at 400 V
• Operating Temperature - Junction: -55°C to 150°C minimum range

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, or Axial equivalent
• Technology: Standard rectifier diode

The SF26G A0G from Taiwan Semiconductor Corporation meets all electrical equivalence criteria and maintains mechanical compatibility through identical package designation (DO-204AC / DO-15). This part is classified as a parametric equivalent and direct substitute for the FR204GP-AP.

Engineering Selection Recommendations

Primary Selection: FR204GP-AP

The FR204GP-AP remains the primary component choice when Micro Commercial Co inventory is available. This part carries active product status, ROHS3 compliance, and REACH unaffected designation, confirming regulatory alignment for current applications.

Substitute Selection: SF26G A0G

The SF26G A0G from Taiwan Semiconductor Corporation is a direct parametric equivalent suitable for applications where FR204GP-AP supply is constrained. This substitute maintains all critical electrical specifications and mechanical compatibility. The SF26G A0G demonstrates superior performance characteristics in reverse recovery time (35 ns versus 150 ns) and lower junction capacitance (20 pF versus 40 pF), which may provide operational advantages in high-frequency switching applications.

Both parts carry identical regulatory compliance status (ROHS3 Compliant, REACH Unaffected) and operate across the same temperature range (-55°C to 150°C junction temperature). Packaging is functionally equivalent in DO-204AC / DO-15 axial through-hole configuration.

Frequently Asked Questions (FAQ)

Q: Can SF26G A0G be used as a direct replacement for FR204GP-AP in existing designs?

A: Yes. The SF26G A0G meets all electrical equivalence criteria for the FR204GP-AP, including voltage rating (400 V), current rating (2 A), forward voltage drop (1.3 V @ 2 A), and reverse leakage current (5 µA @ 400 V). Both components use identical through-hole DO-15 packaging and operate across the same temperature range. No circuit modifications are required.

Q: What are the differences between FR204GP-AP and SF26G A0G?

A: The primary differences are manufacturer origin and reverse recovery time. The SF26G A0G exhibits faster reverse recovery (35 ns versus 150 ns) and lower junction capacitance (20 pF versus 40 pF). These characteristics may improve switching performance in applications operating at higher frequencies, though both parts satisfy the fast recovery classification (≤ 500 ns).

Q: Are there packaging differences between these parts?

A: Both parts are supplied in DO-204AC / DO-15 axial through-hole packages. The FR204GP-AP is supplied in standard packaging, while the SF26G A0G is supplied in cut tape (CT) format. The physical component dimensions and lead configuration are identical, ensuring mechanical compatibility in PCB layouts.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both FR204GP-AP and SF26G A0G carry ROHS3 compliance and REACH unaffected status, confirming compliance with current environmental and hazardous substance regulations.

Q: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on availability and supply chain considerations. The SF26G A0G may be preferred in applications requiring faster switching response due to its superior reverse recovery time specification.

Q: Are there inventory considerations for part selection?

A: Current inventory shows 767 pieces of FR204GP-AP and 831 pieces of SF26G A0G in stock. Selection may be influenced by immediate availability requirements and lead time constraints.
