RL202GP-BP Equivalent & Substitute Parts

Part Overview

The RL202GP-BP is a through-hole rectifier diode rated for 100 V DC reverse voltage and 2 A average rectified current, packaged in DO-15 (DO-204AC) axial configuration. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identification of equivalent and substitute parts is necessary for ongoing maintenance, repair, and legacy system support where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RL202GP-BP is determined by electrical and mechanical compatibility within the following constraints:

Critical Matching 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 DO-204AC, DO-15, or Axial equivalent
• Operating Temperature Range: Must encompass -55°C to 150°C junction temperature

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max): Lower or equal values preferred for thermal efficiency
• Speed: Standard Recovery classification must be maintained
• Current - Reverse Leakage @ Vr: Lower or equal values preferred for leakage performance

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 RL202GP-BP. This part is suitable only for applications where the actual circuit current demand does not exceed 1.5 A.

Engineering Selection Recommendations

1N5392GHB0G Substitution Criteria:

The 1N5392GHB0G is electrically and mechanically compatible with the RL202GP-BP for applications where the circuit current requirement does not exceed 1.5 A. The substitute part carries Active product status and holds AEC-Q101 automotive qualification, providing higher reliability assurance than the end-of-life RL202GP-BP. The 1N5392GHB0G is RoHS3 compliant and carries Moisture Sensitivity Level 1 (Unlimited), indicating superior environmental robustness.

Voltage and Package Compatibility:

Both parts share identical 100 V reverse voltage rating and DO-15 axial through-hole packaging, ensuring direct mechanical and electrical fit in existing PCB layouts and circuit designs.

Current Rating Limitation:

The 1N5392GHB0G current rating of 1.5 A is 25% lower than the RL202GP-BP specification of 2 A. Substitution is valid only when circuit analysis confirms that peak and average rectified current does not exceed 1.5 A under all operating conditions, including transient and fault scenarios.

Forward Voltage Consideration:

The 1N5392GHB0G exhibits a forward voltage of 1.1 V at 1.5 A compared to 1 V at 2 A for the RL202GP-BP. This 0.1 V increase results in marginally higher power dissipation in the substitute part. Thermal design verification is required if the original circuit operates near thermal limits.

Frequently Asked Questions (FAQ)

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

A: Direct replacement is valid only for applications where the actual circuit current does not exceed 1.5 A. Circuit analysis must confirm that peak rectified current, including transient conditions, remains below the 1.5 A rating of the substitute part. If the application requires the full 2 A capability of the RL202GP-BP, the 1N5392GHB0G is not suitable.

Q: Are the packages physically identical?

A: Yes. Both the RL202GP-BP and 1N5392GHB0G use the DO-15 (DO-204AC) axial through-hole package. Physical dimensions and lead spacing are compatible, allowing direct PCB mounting without layout modification.

Q: What is the significance of the 1N5392GHB0G being AEC-Q101 qualified?

A: AEC-Q101 qualification indicates the part meets automotive-grade reliability standards for discrete semiconductors. This certification provides higher assurance of quality control, testing rigor, and long-term performance stability compared to standard commercial-grade components. The RL202GP-BP carries no stated automotive qualification.

Q: How does the forward voltage difference affect circuit performance?

A: The 0.1 V increase in forward voltage (1.1 V versus 1 V) results in approximately 10% higher power dissipation in the substitute part at rated current. For low-current applications, this difference is negligible. For applications operating near the 1.5 A limit, thermal analysis is required to ensure the substitute part does not exceed junction temperature limits.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts carry REACH Unaffected status and EAR99 export classification. The 1N5392GHB0G is RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), indicating superior environmental compliance and handling robustness. The RL202GP-BP carries no stated RoHS or MSL designation.

Q: What inventory status should influence the substitution decision?

A: The 1N5392GHB0G has 941 pieces in stock compared to 631 pieces for the RL202GP-BP. For long-term supply security in legacy system support, the higher inventory level of the substitute part provides greater availability assurance.
