2A05-AP Equivalent & Substitute Parts

Part Overview

The 2A05-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The diode operates across a junction temperature range of -55°C to 150°C and complies with ROHS3 standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2A05-AP are classified into three categories based on electrical and mechanical parameter alignment:

Direct Equivalent (Same Manufacturer): Parts that maintain identical electrical specifications and package designation from the original manufacturer.

Parametric Equivalent (Different Manufacturer): Parts that match all critical electrical parameters (600 V reverse voltage, 2 A average rectified current, forward voltage, reverse leakage, and operating temperature range) and package type, but originate from alternative manufacturers.

Similar Substitute (Reduced Current Rating): Parts that maintain the 600 V reverse voltage and DO-15 package but operate at reduced current ratings (1.5 A instead of 2 A), suitable for applications with lower current demands.

Substitution eligibility is determined by the following criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V minimum
• Current - Average Rectified (Io): 2 A (or lower for similar substitutes)
• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, or Axial
• Operating Temperature - Junction: -55°C ~ 150°C minimum range
• RoHS Status: ROHS3 Compliant

Engineering Selection Recommendations

Primary Selection - RL205GP-AP: This part is the direct equivalent from Micro Commercial Co and maintains active product status. It provides identical electrical specifications and package configuration to the 2A05-AP, ensuring seamless integration into existing designs. This part is recommended for applications requiring no design modification.

Secondary Selection - 2A05GHA0G: This parametric equivalent from Taiwan Semiconductor Corporation matches all critical electrical parameters and adds automotive-grade qualification (AEC-Q101). The part is active and ROHS3 compliant. Selection of this part is appropriate for applications requiring automotive-grade reliability or when sourcing from alternative manufacturers is necessary.

Alternative Selection - SF28GHA0G: This part maintains the 600 V reverse voltage and 2 A current rating with automotive-grade qualification (AEC-Q101). The forward voltage is higher (1.7 V @ 2 A versus 1 V @ 2 A) and recovery speed is faster (≤500ns). This part is suitable for applications where fast recovery characteristics are beneficial and forward voltage dissipation is acceptable.

Reduced Current Alternative - FR155GHA0G: This part operates at 1.5 A average rectified current instead of 2 A, with automotive-grade qualification (AEC-Q101). Selection is limited to applications with current requirements not exceeding 1.5 A.

Frequently Asked Questions (FAQ)

Q: Can RL205GP-AP be used as a direct replacement for 2A05-AP?

A: Yes. RL205GP-AP is manufactured by the same company (Micro Commercial Co) and maintains identical electrical specifications, forward voltage characteristics, recovery speed, reverse leakage, and package configuration. The primary difference is product status: RL205GP-AP is active while 2A05-AP is obsolete.

Q: What is the difference between 2A05GHA0G and 2A05-AP?

A: Both parts share identical electrical specifications (600 V reverse voltage, 2 A current, 1 V forward voltage @ 2 A, standard recovery speed, and 5 µA reverse leakage). The 2A05GHA0G is manufactured by Taiwan Semiconductor Corporation, carries active product status, and includes automotive-grade qualification (AEC-Q101). The 2A05-AP is obsolete.

Q: Can SF28GHA0G replace 2A05-AP in all applications?

A: SF28GHA0G maintains the 600 V reverse voltage and 2 A current rating. However, the forward voltage is higher (1.7 V @ 2 A versus 1 V @ 2 A) and recovery speed is faster (≤500ns versus >500ns). Substitution is valid for applications where these differences do not impact circuit performance.

Q: Is FR155GHA0G suitable for all 2A05-AP applications?

A: FR155GHA0G is suitable only for applications where the average rectified current requirement does not exceed 1.5 A. The part maintains the 600 V reverse voltage rating and DO-15 package. Applications requiring the full 2 A rating must use alternative parts.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive-grade qualification standard. Parts carrying this qualification (2A05GHA0G, SF28GHA0G, FR155GHA0G) meet automotive industry reliability and testing requirements. This qualification is not present on the original 2A05-AP.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RL205GP-AP, 2A05GHA0G, SF28GHA0G, FR155GHA0G) are ROHS3 compliant, matching the compliance status of the original 2A05-AP.

Q: What is the difference between DO-15 and DO-204AC packaging?

A: DO-15 and DO-204AC are equivalent package designations for the same axial through-hole diode package. All substitute parts use this same physical package configuration, ensuring mechanical compatibility.
