RL206-TP General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The RL206-TP 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, which necessitates identification of active equivalent and substitute components for ongoing design support and procurement.

The RL206-TP operates across a junction temperature range of -55°C to 150°C and exhibits standard recovery characteristics with reverse recovery time exceeding 500 ns. The forward voltage drop is specified at 1 V maximum at 2 A forward current, with reverse leakage current of 5 µA at rated voltage.

Substitute Part Grouping Explanation

Substitution of the RL206-TP is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 800 V minimum
Mounting Type: Through Hole
Package / Case: DO-204AC, DO-15, or Axial equivalent
RoHS Compliance: ROHS3 Compliant preferred for regulatory alignment

Secondary Compatibility Factors:

Current - Average Rectified (Io): Equal to or greater than 2 A
Voltage - Forward (Vf): Acceptable within application circuit design margins
Recovery Speed: Standard or Fast recovery acceptable
Operating Temperature Range: Must encompass application requirements

Direct Equivalent: The RL206GP-TP from Micro Commercial Co is the direct active equivalent, maintaining identical electrical specifications while offering active product status and improved packaging options (Tape & Reel).

Functional Substitutes: Parts with 800 V reverse voltage rating and through-hole DO-15 packaging qualify as functional substitutes when current rating meets or exceeds 2 A. Lower current-rated parts (1 A or 1.5 A) function as substitutes only in applications where actual circuit current demand does not exceed their ratings.

Engineering Selection Recommendations

Recommended Primary Substitute: RL206GP-TP

The RL206GP-TP is the optimal replacement for the obsolete RL206-TP. This part maintains identical electrical specifications (800 V, 2 A, 1 V forward voltage) and operating temperature range (-55°C to 150°C). Both parts share the same base product number (RL206) and are manufactured by Micro Commercial Co. The RL206GP-TP carries active product status and ROHS3 compliance, eliminating obsolescence risk. Packaging is available in Tape & Reel format, supporting modern manufacturing workflows.

Recommended Secondary Substitutes: GPP20K-E3/73 or EGP20K

For applications requiring 2 A current capacity with 800 V reverse voltage rating, the GPP20K-E3/73 (Vishay General Semiconductor) provides active product status and ROHS3 compliance. This part specifies 1.1 V forward voltage at 2 A, representing improved performance over the RL206-TP. The GPP20K-E3/73 operates across -55°C to 150°C, matching the original part's temperature range.

The EGP20K (Nexperia USA Inc.) also provides 2 A at 800 V in DO-15 packaging but carries obsolete product status and non-compliant RoHS classification, limiting its suitability for new designs.

Alternative Substitutes for Current-Reduced Applications: GP15K-E3/54, GP15K-E3/73, 1N5398GP-E3/54

When circuit design permits operation at 1.5 A maximum current, the GP15K-E3/54 and GP15K-E3/73 (Vishay General Semiconductor, SUPERECTIFIER® series) offer active status and ROHS3 compliance. These parts specify 1.1 V forward voltage at 1.5 A and standard recovery characteristics. The 1N5398GP-E3/54 provides similar 1.5 A capability with 1.4 V forward voltage specification.

Lower Current Alternatives: 1N5621GP-E3/54, 1N5621GP-E3/73, BYV26DGP-E3/54, BYV26DGP-E3/73

For applications limited to 1 A maximum current, the 1N5621GP series (Vishay SUPERECTIFIER®) and BYV26DGP series provide fast recovery characteristics (≤500 ns) with 800 V reverse voltage rating. These parts carry active product status and ROHS3 compliance. The 1N5621 series specifies 1.2 V forward voltage at 1 A, while the BYV26DGP series specifies 2.5 V forward voltage at 1 A.

Frequently Asked Questions (FAQ)

Q: Can the RL206GP-TP directly replace the RL206-TP without circuit modification?

A: Yes. The RL206GP-TP is the direct active equivalent with identical electrical specifications, operating temperature range, and package type. No circuit modification is required.

Q: What is the primary difference between the RL206-TP and RL206GP-TP?

A: The RL206-TP is classified as obsolete, while the RL206GP-TP maintains active product status. Both parts share identical electrical ratings (800 V, 2 A, 1 V forward voltage). The RL206GP-TP is available in Tape & Reel packaging, supporting automated assembly processes.

Q: Can 1.5 A rated diodes substitute for the 2 A RL206-TP?

A: Substitution is possible only when circuit analysis confirms that actual forward current does not exceed 1.5 A under all operating conditions, including transient events. The 1N5398GP-E3/54 and GP15K series provide this current rating with 800 V reverse voltage and ROHS3 compliance.

Q: What is the difference between standard recovery and fast recovery diodes?

A: The RL206-TP specifies standard recovery with reverse recovery time exceeding 500 ns. Fast recovery diodes (1N5621GP, BYV26DGP series) exhibit reverse recovery time of 75-300 ns. Fast recovery diodes reduce switching losses in high-frequency applications but are not required for the RL206-TP's standard recovery specification.

Q: Are all substitute parts ROHS3 compliant?

A: All recommended substitutes carry ROHS3 compliance except the EGP20K, which is classified as RoHS non-compliant. For new designs and procurement, ROHS3-compliant parts are required to meet regulatory requirements.

Q: What is the significance of the DO-15 and DO-204AC package designations?

A: DO-15 and DO-204AC are equivalent package designations for the same axial through-hole diode form factor. Both support identical PCB mounting and lead spacing. Manufacturers may use either designation interchangeably.

Q: Can the BYV26DGP-E3/54 substitute for the RL206-TP in a 2 A application?

A: No. The BYV26DGP-E3/54 is rated for 1 A maximum average rectified current. Using this part in a 2 A application exceeds its current rating and creates reliability risk. The GPP20K-E3/73 or RL206GP-TP are appropriate for 2 A applications.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in Tape & Reel (TR), Cut Tape (CT), Bulk, and Tape & Box (TB) formats. The RL206GP-TP offers Tape & Reel packaging for automated assembly. Individual application requirements determine optimal packaging selection.

Q: How does forward voltage specification affect circuit performance?

A: Forward voltage drop directly impacts power dissipation and voltage regulation in rectifier circuits. The RL206-TP specifies 1 V at 2 A. Substitutes with lower forward voltage (GPP20K-E3/73 at 1.1 V, GP15K at 1.1 V) reduce power loss. Substitutes with higher forward voltage (BYV26DGP at 2.5 V) increase power dissipation and require thermal analysis verification.

Q: Is the RL206-TP suitable for new product designs?

A: No. The RL206-TP is classified as obsolete. New designs must specify active equivalent parts such as RL206GP-TP or GPP20K-E3/73 to ensure long-term component availability and supply chain continuity.
