FR505-TP Equivalent & Substitute Parts

Part Overview

The FR505-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 5 A average rectified current in a DO-201AD axial through-hole package. This part is classified as obsolete, necessitating identification of active equivalent components for ongoing design support and procurement continuity. The FR505-TP remains functionally available through existing inventory but is no longer in active production status.

Engineering Selection Recommendations

The FR505GP-TP is a direct electrical and mechanical equivalent to the FR505-TP. Both components share identical electrical specifications, including voltage rating, current capacity, forward voltage drop, reverse recovery time, leakage current, and capacitance characteristics. Both are manufactured by Micro Commercial Co and packaged in the DO-201AD axial through-hole format with identical operating temperature ranges.

The primary distinction between these parts is product status and packaging format. The FR505-TP is classified as obsolete, while the FR505GP-TP maintains active production status. The FR505GP-TP is supplied in tape & reel packaging, whereas the FR505-TP is supplied in bulk format. This packaging difference does not affect electrical performance or circuit compatibility.

Both components comply with ROHS3 standards and carry identical ECCN and HTSUS classifications. The FR505GP-TP is the recommended selection for new designs and ongoing procurement due to its active product status and continued manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the FR505GP-TP be used as a direct replacement for the FR505-TP in existing circuits?

A: Yes. The FR505GP-TP is electrically and mechanically identical to the FR505-TP. All electrical parameters, including voltage rating, current capacity, forward voltage, reverse recovery time, and leakage current, are identical. The DO-201AD axial through-hole package is the same, enabling direct board-level substitution without circuit modification.

Q: What is the difference between the FR505-TP and FR505GP-TP?

A: The primary differences are product status and packaging format. The FR505-TP is obsolete and supplied in bulk packaging. The FR505GP-TP is in active production and supplied in tape & reel (TR) format. All electrical and mechanical specifications are identical.

Q: Does the tape & reel packaging of the FR505GP-TP affect its electrical performance?

A: No. Packaging format does not affect electrical performance or functional characteristics. Tape & reel packaging is a supply and handling format used for automated assembly processes. The component itself is identical to bulk-packaged versions.

Q: Are both parts RoHS compliant?

A: Yes. Both the FR505-TP and FR505GP-TP are ROHS3 compliant and carry identical environmental compliance certifications.

Q: Which part should be selected for new designs?

A: The FR505GP-TP should be selected for new designs. It is in active production status, ensuring long-term availability and manufacturing support. The FR505-TP is obsolete and should not be specified for new applications.

Q: Can these parts be used interchangeably in high-frequency or high-temperature applications?

A: Yes, within the specified operating parameters. Both parts are rated for junction temperatures from -55°C to 150°C and feature fast recovery characteristics (≤ 500 ns). They are suitable for applications within these thermal and frequency ranges.
