R1500F-AP Equivalent & Substitute Parts

Part Overview

The R1500F-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1500 V DC reverse voltage with 500 mA average rectified current in a DO-41 through-hole 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 and mechanical compatibility across voltage, current, and thermal specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the R1500F-AP is determined by the following critical electrical and mechanical parameters:

Voltage Rating: Substitute parts must maintain a DC reverse voltage (Vr) rating of 1500 V or greater to ensure equivalent reverse bias protection.

Current Rating: Substitute parts must support an average rectified current (Io) of 500 mA or greater to handle the same load conditions.

Speed Classification: Substitute parts must be classified as fast recovery diodes with reverse recovery time (trr) of 500 ns or less to maintain switching performance characteristics.

Reverse Leakage: Substitute parts must exhibit reverse leakage current of 5 µA or less at 1500 V to ensure equivalent blocking performance.

Package and Mounting: Substitute parts must use through-hole mounting in DO-204AL or DO-41 axial packages to ensure mechanical and electrical compatibility with existing PCB designs.

Compliance: Substitute parts must maintain ROHS3 compliance and equivalent moisture sensitivity levels (MSL 1 - Unlimited).

The RGP02-15E-E3/54 meets all substitution criteria and is classified as an active product.

Parameter Comparison

Engineering Selection Recommendations

The RGP02-15E-E3/54 is the qualified substitute for the obsolete R1500F-AP based on the following factors:

Product Status: The RGP02-15E-E3/54 is classified as an active product with current manufacturing and distribution support, whereas the R1500F-AP is obsolete. Selection of the active substitute ensures long-term availability and supply chain continuity.

Electrical Equivalence: Both parts maintain identical voltage (1500 V), current (500 mA), and reverse leakage (5 µA @ 1500 V) specifications. The substitute exhibits improved reverse recovery time (300 ns versus 500 ns), which provides superior switching performance without introducing incompatibility.

Compliance Certification: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance.

Thermal Performance: The RGP02-15E-E3/54 provides an extended operating temperature range (-65 to 175°C versus -55 to 150°C), offering improved thermal margin for demanding applications.

Package Compatibility: Both parts use identical DO-204AL/DO-41 axial through-hole packages, ensuring direct mechanical and electrical compatibility with existing PCB layouts without design modification.

Frequently Asked Questions (FAQ)

Q: Can the RGP02-15E-E3/54 directly replace the R1500F-AP in existing designs?

A: Yes. Both parts share identical voltage (1500 V), current (500 mA), reverse leakage (5 µA @ 1500 V), and package specifications (DO-204AL/DO-41 axial through-hole). No PCB layout or schematic modifications are required.

Q: What is the significance of the lower forward voltage (Vf) in the RGP02-15E-E3/54?

A: The RGP02-15E-E3/54 exhibits a forward voltage of 1.8 V at 100 mA compared to 2.4 V at 500 mA for the R1500F-AP. Lower forward voltage reduces power dissipation and heat generation during conduction, improving overall circuit efficiency without affecting substitution compatibility.

Q: Does the faster reverse recovery time (trr) of the RGP02-15E-E3/54 affect circuit operation?

A: The RGP02-15E-E3/54 provides a reverse recovery time of 300 ns compared to 500 ns for the R1500F-AP. Faster recovery time improves switching performance and reduces switching losses, particularly in high-frequency applications. This represents an enhancement rather than a compatibility concern.

Q: Are there packaging differences between the two parts?

A: Both parts use identical DO-204AL/DO-41 axial through-hole packages. The RGP02-15E-E3/54 is supplied in cut tape (CT) packaging, which is standard for active production parts. No mechanical or electrical differences exist between the packages.

Q: What is the impact of the extended temperature range in the RGP02-15E-E3/54?

A: The RGP02-15E-E3/54 operates from -65 to 175°C compared to -55 to 150°C for the R1500F-AP. The extended range provides additional thermal margin and allows operation in more demanding temperature environments without performance degradation.

Q: Why is the R1500F-AP classified as obsolete?

A: Obsolescence indicates that the manufacturer has discontinued production and distribution of this part. The RGP02-15E-E3/54 is an active equivalent that provides identical electrical and mechanical performance with current manufacturing support.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the R1500F-AP and RGP02-15E-E3/54 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance for all applications.
