RL205-TP General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The RL205-TP 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 axial package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The RL205-TP operates across a junction temperature range of -55°C to 150°C and exhibits standard recovery characteristics with forward voltage of 1 V at 2 A. Substitution is required to access active product status alternatives while maintaining electrical and mechanical compatibility within specified application parameters.

Engineering Selection Recommendations

Primary Direct Substitute:

RL205GP-TP is the recommended primary substitute. This part is manufactured by the same supplier (Micro Commercial Co) as the obsolete RL205-TP and provides identical electrical specifications: 600 V reverse voltage, 2 A average rectified current, 1 V forward voltage at 2 A, and standard recovery characteristics. The RL205GP-TP maintains the same DO-15 package and operating temperature range (-55°C to 150°C). Product status is active, ensuring long-term availability. RoHS3 compliance and REACH unaffected status match the original part.

Secondary Direct Substitutes (600 V, 2 A Rating):

EGP20J (Fairchild Semiconductor) meets the full 2 A current requirement and 600 V voltage specification in DO-15 package. This part features fast recovery characteristics (≤500ns) compared to the standard recovery of RL205-TP, providing improved switching performance. Operating temperature range extends to -65°C to 150°C. Forward voltage is 1.7 V @ 2 A, which is higher than RL205-TP but within acceptable rectifier diode parameters. Product status is active with RoHS3 compliance.

BYW36-TR and BYW54-TR (Vishay General Semiconductor) both provide 600 V, 2 A ratings in SOD-57 axial package. BYW36-TR features fast recovery (200 ns) with forward voltage of 1.1 V @ 1 A. BYW54-TR provides standard recovery with forward voltage of 1 V @ 1 A. Both parts are active products with extended temperature ranges (-55°C to 175°C) and RoHS3 compliance. Package change from DO-15 to SOD-57 requires mechanical board layout verification.

Functional Equivalents (600 V, Reduced Current Rating):

1N6628 (Microchip Technology) provides 1.75 A average rectified current at 600 V in A-package axial format. This part features fast recovery (45 ns) and is suitable for applications where 2 A is not required. Product status is active with RoHS3 compliance and operating temperature range of -65°C to 150°C.

1N5397GP-E3/54 and 1N5397GP-E3/73 (Vishay General Semiconductor) provide 1.5 A at 600 V in DO-204AC package with standard recovery characteristics. Both are active products with extended temperature range (-65°C to 175°C) and RoHS3 compliance.

GP15J-E3/54 and GP15J-E3/73 (Vishay General Semiconductor) provide 1.5 A at 600 V in DO-204AC package with forward voltage of 1.1 V @ 1.5 A. Both are active products with RoHS3 compliance and extended temperature range.

1N5619GP-E3/54 (Vishay General Semiconductor) provides 1 A at 600 V with fast recovery characteristics (250 ns) in DO-204AC package. This part is suitable for lower current applications and is an active product with RoHS3 compliance.

All substitute parts maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original RL205-TP specification.

Frequently Asked Questions (FAQ)

Q: Can RL205GP-TP be used as a direct replacement for RL205-TP?

A: Yes. RL205GP-TP is a direct substitute manufactured by Micro Commercial Co with identical electrical specifications (600 V, 2 A), same forward voltage (1 V @ 2 A), identical recovery characteristics, and the same DO-15 package. The primary difference is product status: RL205GP-TP is active while RL205-TP is obsolete. Packaging format differs (Tape & Reel vs. standard), but electrical and mechanical compatibility is complete.

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

A: DO-15 and DO-204AC are equivalent designations for the same axial through-hole package. Both refer to a cylindrical diode package with leads at each end, suitable for through-hole PCB mounting. Parts specified as DO-204AC (DO-15) or DO-15 are mechanically and electrically interchangeable in board layout.

Q: Can I use a 1.5 A rated diode in place of a 2 A rated diode?

A: Substitution with lower current-rated parts (1.5 A, 1.75 A) is permissible only if the application circuit does not require the full 2 A capability. The 600 V voltage rating and package compatibility must be maintained. Forward voltage and recovery characteristics may differ; verify that these parameters are acceptable for the specific application. Parts such as 1N5397GP-E3/54, GP15J-E3/54, and 1N6628 are suitable for reduced-current applications.

Q: What is the significance of recovery speed (Standard vs. Fast)?

A: Recovery speed indicates the time required for the diode to transition from conducting to blocking state. Standard recovery (>500ns) is suitable for general purpose rectification applications. Fast recovery (≤500ns) provides improved switching performance and reduced switching losses, beneficial in high-frequency or switching power supply applications. The RL205-TP specifies standard recovery; substitutes with fast recovery (EGP20J, BYW36-TR, 1N5619GP-E3/54) provide enhanced performance without compromising compatibility.

Q: Are BYW36-TR and BYW54-TR suitable replacements despite the SOD-57 package change?

A: BYW36-TR and BYW54-TR provide electrical equivalence (600 V, 2 A) but require mechanical board layout modification due to SOD-57 package format. SOD-57 is an axial through-hole package similar to DO-15 in function but with different physical dimensions. Substitution is permissible if PCB layout can accommodate the different package geometry. Both parts are active products with RoHS3 compliance and extended temperature ranges.

Q: What compliance certifications should I verify when selecting a substitute?

A: All listed substitute parts maintain RoHS3 compliance and REACH unaffected status, matching the original RL205-TP specification. ECCN classification (EAR99) and HTSUS code (8541.10.0080) are consistent across all parts. Verify that the selected substitute meets your specific regulatory requirements for the target application and geographic market.

Q: Can EGP20J be used despite higher forward voltage (1.7 V vs. 1 V)?

A: EGP20J forward voltage of 1.7 V @ 2 A is higher than RL205-TP at 1 V @ 2 A. This difference results in increased power dissipation and heat generation in the diode. Substitution is permissible if thermal design and circuit performance remain acceptable with the higher forward voltage drop. Applications with tight voltage regulation or high current density may require thermal analysis before substitution.

Q: What is the advantage of Vishay SUPERECTIFIER® series parts?

A: Vishay SUPERECTIFIER® series parts (1N5397GP, GP15J, 1N5619GP) are optimized general purpose rectifier diodes with controlled recovery characteristics and low leakage current. These parts provide consistent performance across temperature ranges and are available in multiple current ratings (1 A, 1.5 A). Extended operating temperature range (-65°C to 175°C) provides design margin compared to RL205-TP (-55°C to 150°C).

Q: Is Microchip 1N6628 suitable for 2 A applications?

A: 1N6628 is rated for 1.75 A average rectified current, which is below the 2 A specification of RL205-TP. This part is suitable for applications where sustained current does not exceed 1.75 A. The part features fast recovery (45 ns) and is available in A-package axial format. Verify application current requirements before substitution.
