R1500-AP Equivalent & Substitute Parts

Part Overview

The R1500-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1500 V DC reverse voltage and 500 mA average rectified current in a through-hole DO-41 package. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating the through-hole axial package format.

Substitute Part Grouping Explanation

Substitution of the obsolete R1500-AP is based on electrical parameter equivalence and package compatibility. The primary substitute, RGP02-15E-E3/54, satisfies substitution criteria through the following matched parameters:

Matched Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 1500 V (identical)
• Current - Average Rectified (Io): 500 mA (identical)
• Current - Reverse Leakage @ Vr: 5 µA @ 1500 V (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: DO-204AL, DO-41, Axial (identical)
• RoHS Status: ROHS3 Compliant (identical)

Acceptable Parameter Variations:

• Voltage - Forward (Vf) (Max): 1.8 V @ 100 mA (substitute) versus 2 V @ 500 mA (main part) — lower forward voltage represents improved performance
• Operating Temperature - Junction: -65°C to 175°C (substitute) versus -55°C to 150°C (main part) — extended temperature range provides broader operational capability
• Recovery Speed: Fast Recovery ≤ 500 ns (substitute) versus Standard Recovery > 500 ns (main part) — faster recovery represents enhanced switching characteristics

The RGP02-15E-E3/54 is an active product with current inventory availability, eliminating obsolescence constraints.

Engineering Selection Recommendations

The RGP02-15E-E3/54 manufactured by Vishay General Semiconductor - Diodes Division is the direct substitute for the obsolete R1500-AP. Selection is based on the following engineering criteria:

Compliance and Certification: Both parts maintain ROHS3 compliance and carry identical ECCN (EAR99) and HTSUS (8541.10.0070) classifications, ensuring regulatory equivalence for procurement and export documentation.

Product Status: The R1500-AP is classified as obsolete with no active manufacturing. The RGP02-15E-E3/54 is an active product with 11,609 units in current inventory, providing supply chain continuity and long-term availability.

Electrical Equivalence: Critical parameters—reverse voltage (1500 V), average rectified current (500 mA), and reverse leakage current (5 µA @ 1500 V)—are identical between both parts. The substitute exhibits improved forward voltage characteristics and faster recovery speed, representing performance enhancement rather than degradation.

Thermal Performance: The substitute's extended operating temperature range (-65°C to 175°C versus -55°C to 150°C) accommodates broader environmental conditions without additional thermal management requirements.

Package Compatibility: Both parts utilize identical through-hole axial packaging (DO-204AL, DO-41), ensuring direct mechanical and electrical compatibility in existing PCB layouts without redesign.

Frequently Asked Questions (FAQ)

Q: Can the RGP02-15E-E3/54 directly replace the R1500-AP in existing designs?

A: Yes. The RGP02-15E-E3/54 is electrically and mechanically equivalent to the R1500-AP across all critical parameters. Reverse voltage, average rectified current, reverse leakage current, and package format are identical. The substitute exhibits improved forward voltage and recovery speed characteristics, representing performance enhancement.

Q: What is the significance of the faster recovery speed in the RGP02-15E-E3/54?

A: The RGP02-15E-E3/54 features fast recovery (≤ 500 ns) compared to the R1500-AP's standard recovery (> 500 ns). Faster recovery reduces switching losses and improves efficiency in high-frequency rectification applications. This represents a performance improvement and does not introduce compatibility issues.

Q: Are there package differences between the R1500-AP and RGP02-15E-E3/54?

A: No. Both parts use identical through-hole axial packaging designated as DO-204AL and DO-41. Physical dimensions, lead spacing, and PCB mounting requirements are equivalent. No layout modifications are required.

Q: How do the forward voltage specifications compare?

A: The R1500-AP specifies 2 V maximum forward voltage at 500 mA. The RGP02-15E-E3/54 specifies 1.8 V maximum forward voltage at 100 mA. The substitute's lower forward voltage reduces power dissipation and heat generation, providing operational advantage in thermal-constrained applications.

Q: What is the temperature operating range difference?

A: The R1500-AP operates from -55°C to 150°C junction temperature. The RGP02-15E-E3/54 operates from -65°C to 175°C. The substitute's extended range accommodates both lower and higher temperature extremes, providing greater design flexibility without performance compromise.

Q: Are both parts RoHS compliant?

A: Yes. Both the R1500-AP and RGP02-15E-E3/54 are ROHS3 compliant. Regulatory and environmental requirements are equivalent.

Q: What is the availability status of each part?

A: The R1500-AP is obsolete with no active manufacturing. The RGP02-15E-E3/54 is an active product with 11,609 units currently in stock, ensuring supply chain continuity and procurement reliability.

Q: Are there any reverse leakage current differences?

A: No. Both parts specify identical reverse leakage current of 5 µA at 1500 V reverse voltage. Leakage performance is equivalent.
