Key Parameters

Substitute Part Grouping Explanation

Substitute components for the RL204GP-AP are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 2 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 400 V
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, Axial

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts identified in this reference maintain all critical electrical specifications and physical form factors. Minor variations in capacitance values (within the same order of magnitude) do not affect substitution validity for general-purpose rectification applications.

Parameter Comparison

Engineering Selection Recommendations

2A04G A0G (Taiwan Semiconductor Corporation)

This substitute maintains full electrical and mechanical equivalence to the RL204GP-AP. The component is in Active product status, ensuring continued availability and supply chain stability. It carries ROHS3 compliance and MSL 1 rating identical to the original part. The 5 pF reduction in capacitance (from 20 pF to 15 pF) does not affect substitution validity for standard rectification circuits. Selection of this part is appropriate for general-purpose applications where automotive qualification is not required.

2A04GHA0G (Taiwan Semiconductor Corporation)

This substitute provides identical electrical and mechanical specifications to the RL204GP-AP with the additional qualification of AEC-Q101 automotive-grade certification. The component is in Active product status. The 5 pF capacitance reduction is equivalent to the 2A04G A0G variant. Selection of this part is appropriate for applications requiring automotive-grade components or where AEC-Q101 qualification is mandated by design or procurement specifications.

Both substitute parts are suitable for direct replacement in existing designs using the RL204GP-AP. Component selection between the two Taiwan Semiconductor options depends on whether automotive-grade qualification is required for the application.

Frequently Asked Questions (FAQ)

Q: Can the 2A04G A0G and 2A04GHA0G be used interchangeably with the RL204GP-AP?

A: Both Taiwan Semiconductor parts meet all electrical and mechanical parameters of the RL204GP-AP. The primary difference is that 2A04GHA0G carries AEC-Q101 automotive qualification. Selection depends on application requirements. If automotive qualification is not specified, either part is electrically equivalent.

Q: What is the significance of the capacitance difference between the RL204GP-AP (20 pF) and the substitute parts (15 pF)?

A: The capacitance values are measured at identical conditions (4V, 1MHz). The 5 pF difference does not affect substitution validity for general-purpose rectification applications. Both values fall within acceptable ranges for standard recovery diodes in this voltage and current class.

Q: Why is the RL204GP-AP marked as "Not For New Designs"?

A: This designation indicates the part has been superseded by the manufacturer. For new designs, the Taiwan Semiconductor alternatives (2A04G A0G or 2A04GHA0G) are recommended. For legacy system maintenance and repair, these substitutes provide equivalent functionality.

Q: Are the DO-15 and DO-204AC package designations equivalent?

A: Yes. DO-15 and DO-204AC refer to the same axial through-hole package form factor. Both the original part and substitute parts use this identical package, ensuring mechanical compatibility in PCB layouts and through-hole mounting applications.

Q: What compliance certifications apply to all three parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. The 2A04GHA0G additionally carries AEC-Q101 automotive qualification.

Q: Can these diodes be used in high-frequency switching applications?

A: All parts are classified as Standard Recovery diodes with recovery time >500ns at >200mA. This specification indicates suitability for standard rectification and power supply applications. High-frequency switching applications require fast recovery diodes with significantly lower recovery times.
