RL206-AP Equivalent & Substitute Parts

Part Overview

The RL206-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement continuity. The RL206-AP operates across a junction temperature range of -55°C to 150°C and complies with ROHS3 standards.

Substitute Part Grouping Explanation

Substitution of the RL206-AP is determined by strict equivalence across the following critical parameters:

Voltage Rating: 800 V DC reverse voltage (Vr) maximum
Current Rating: 2 A average rectified current (Io)
Forward Voltage: 1 V maximum at 2 A forward current
Reverse Leakage: 5 µA at 800 V
Recovery Speed: Standard recovery >500 ns at >200 mA
Package Type: DO-15 or DO-204AC (equivalent axial through-hole packages)
Temperature Range: -55°C to 150°C junction operating range
Compliance: ROHS3 compliant

Substitute parts are grouped into two categories:

Direct Manufacturer Substitute: Parts from the same manufacturer (Micro Commercial Co) with identical electrical specifications and active product status.

Parametric Equivalent Substitutes: Parts from alternative manufacturers (Taiwan Semiconductor Corporation) that meet all electrical and mechanical parameters, including standard and automotive-grade variants with AEC-Q101 qualification.

Engineering Selection Recommendations

RL206GP-AP is the primary substitute for the obsolete RL206-AP. Both parts are manufactured by Micro Commercial Co and share identical electrical specifications, voltage ratings, current ratings, and temperature operating ranges. The RL206GP-AP maintains active product status and ROHS3 compliance. The packaging difference (Tape & Box versus standard packaging) does not affect electrical or mechanical compatibility. This part is suitable for direct replacement in all applications where the RL206-AP was originally specified.

2A06G A0G and 2A06GHA0G are parametric equivalents manufactured by Taiwan Semiconductor Corporation. Both parts meet all critical electrical parameters: 800 V reverse voltage, 2 A average rectified current, 1 V forward voltage at 2 A, and 5 µA reverse leakage at 800 V. Both maintain the -55°C to 150°C operating temperature range and ROHS3 compliance. The capacitance specification is slightly lower (15 pF versus 20 pF), which remains within acceptable tolerance for general-purpose rectification applications. The 2A06GHA0G variant includes automotive-grade qualification (AEC-Q101), making it suitable for applications requiring automotive-level reliability and traceability.

Selection between these substitutes depends on supply chain availability, procurement lead times, and application-specific requirements. All three substitute parts are electrically and mechanically compatible with the RL206-AP.

Frequently Asked Questions (FAQ)

Q: Can RL206GP-AP be used as a direct replacement for RL206-AP?

A: Yes. The RL206GP-AP is a direct manufacturer substitute with identical electrical specifications, voltage ratings, current ratings, forward voltage characteristics, reverse leakage, recovery speed, and operating temperature range. The only difference is packaging format (Tape & Box) and active product status versus obsolete status.

Q: What is the difference between 2A06G A0G and 2A06GHA0G?

A: Both parts are parametrically equivalent to the RL206-AP with identical voltage, current, and temperature specifications. The 2A06GHA0G includes automotive-grade qualification (AEC-Q101) and is designated for automotive applications. The 2A06G A0G is the standard industrial variant. Electrical performance is equivalent.

Q: Are the DO-15 and DO-204AC packages interchangeable?

A: Yes. DO-15 and DO-204AC are equivalent axial through-hole package designations for the same physical form factor. All substitute parts listed use these equivalent package types and are mechanically compatible with RL206-AP footprints.

Q: Does the lower capacitance (15 pF) of the Taiwan Semiconductor parts affect performance?

A: The capacitance difference (15 pF versus 20 pF at 4V, 1MHz) is within acceptable tolerance for general-purpose rectifier applications. Both values meet the electrical requirements for standard recovery rectification. Application-specific circuit analysis is not required for this parameter variance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (RL206GP-AP, 2A06G A0G, and 2A06GHA0G) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the RL206-AP.

Q: Which substitute should be selected for new designs?

A: For new designs, RL206GP-AP is recommended as the primary choice due to manufacturer continuity with the original RL206-AP. For automotive applications, 2A06GHA0G with AEC-Q101 qualification is appropriate. For general industrial applications, 2A06G A0G provides equivalent performance at potentially lower cost.
