RL202GP-AP Equivalent & Substitute Parts

Part Overview

The RL202GP-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 2 A average rectified current in a DO-15 through-hole package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original part is no longer readily available or where design flexibility permits component substitution within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RL202GP-AP is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 100 V
• Current - Average Rectified (Io): Must equal or exceed 2 A
• Mounting Type: Must be Through Hole
• Package / Case: Must be compatible with DO-15 or DO-204AC form factor
• Operating Temperature Range: Must encompass -55°C to 150°C junction temperature
• Recovery Speed: Must be Standard Recovery classification

Acceptable Variation Parameters:

• Forward Voltage (Vf): Substitute parts may have forward voltage specifications within standard rectifier diode tolerances
• Reverse Leakage Current: Substitute parts must not exceed specified leakage at rated voltage
• Capacitance: Substitute parts may vary within standard specifications

The substitute part 1N5392GHB0G meets the voltage and package requirements but operates at a reduced current rating of 1.5 A, which is below the 2 A specification of the main part. This part is suitable only for applications where the actual circuit current demand does not exceed 1.5 A.

Engineering Selection Recommendations

1N5392GHB0G Selection Criteria:

The 1N5392GHB0G is an active product manufactured by Taiwan Semiconductor Corporation and holds AEC-Q101 automotive qualification. This part is suitable as a substitute for the RL202GP-AP in applications where the circuit current requirement does not exceed 1.5 A at 100 V reverse voltage. The part maintains equivalent reverse voltage rating, recovery speed, reverse leakage characteristics, and operating temperature range.

The primary limitation of this substitute is the reduced average rectified current rating (1.5 A versus 2 A). Circuit analysis must confirm that actual operating current remains within the 1.5 A specification. The substitute part exhibits slightly higher forward voltage (1.1 V at 1.5 A versus 1 V at 2 A) and lower capacitance (15 pF versus 20 pF), both of which are within acceptable ranges for general-purpose rectifier applications.

The active product status of the 1N5392GHB0G provides supply chain continuity and availability advantages over the end-of-life RL202GP-AP. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 1N5392GHB0G directly replace the RL202GP-AP in all applications?

A: Direct replacement is possible only in applications where the circuit current does not exceed 1.5 A. The substitute part is rated for 1.5 A average rectified current, while the original part is rated for 2 A. Circuit analysis must verify that actual operating current remains within the substitute part's specification.

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

A: The DO-15 and DO-204AC designations refer to the same physical package form factor. Both the RL202GP-AP and 1N5392GHB0G use this axial through-hole package, ensuring mechanical compatibility in PCB layouts and breadboard applications.

Q: What is the significance of the AEC-Q101 qualification on the 1N5392GHB0G?

A: AEC-Q101 is an automotive industry qualification standard. The 1N5392GHB0G meets this qualification, indicating it has undergone automotive-grade reliability testing. This qualification does not affect general-purpose rectifier applications but indicates higher quality assurance standards.

Q: How do the forward voltage specifications differ between these parts?

A: The RL202GP-AP specifies 1 V maximum forward voltage at 2 A, while the 1N5392GHB0G specifies 1.1 V maximum at 1.5 A. The difference is within normal rectifier diode tolerances and does not affect circuit functionality in standard rectification applications. Forward voltage differences may introduce minor variations in power dissipation calculations.

Q: Is the reverse leakage current specification identical between both parts?

A: Yes, both parts specify 5 µA maximum reverse leakage current at 100 V. This parameter is equivalent and does not present a substitution concern.

Q: What does "Not For New Designs" mean for the RL202GP-AP?

A: This designation indicates the part has reached end-of-life status and the manufacturer no longer recommends its use in new product designs. Existing inventory may remain available, but long-term supply cannot be guaranteed. The 1N5392GHB0G, classified as "Active," is the recommended path for new designs and ongoing production.

Q: Are there any temperature-related differences between these parts?

A: Both parts operate across the identical junction temperature range of -55°C to 150°C. Temperature performance is equivalent, and no thermal derating adjustments are required when substituting between these parts.
