FR501-AP Equivalent & Substitute Parts

Part Overview

The FR501-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 50 V DC reverse voltage and 5 A average rectified current in a DO-201AD axial through-hole package. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The FR501GP-AP serves as the direct active substitute, offering identical electrical and mechanical specifications with current manufacturing status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR501-AP with the FR501GP-AP is based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical performance criteria: reverse voltage rating (50 V), average rectified current (5 A), forward voltage drop (1.35 V @ 5 A), reverse recovery time (150 ns), reverse leakage current (10 µA @ 50 V), junction capacitance (65 pF @ 4V, 1MHz), and package configuration (DO-201AD axial through-hole). The substitution is valid because all allowed electrical parameters, thermal operating range (-55°C to 150°C), and mechanical mounting characteristics are identical between the two part numbers. The primary distinction is product status: FR501-AP is obsolete while FR501GP-AP is active, making the latter the appropriate selection for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

The FR501GP-AP is the direct equivalent substitute for the FR501-AP. Selection of FR501GP-AP is based on the following factors:

Product Status: FR501-AP is classified as obsolete, whereas FR501GP-AP maintains active manufacturing status. For new designs, production builds, and long-term supply chain planning, FR501GP-AP is the appropriate choice.

Compliance and Certifications: Both parts carry identical RoHS3 compliance and Moisture Sensitivity Level (MSL) 1 ratings, ensuring equivalent environmental and regulatory standing. Both are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Electrical and Mechanical Equivalence: All electrical parameters, thermal operating range, and package specifications are identical. Direct pin-for-pin and functional substitution is valid without circuit modification.

Inventory Availability: FR501GP-AP is currently in stock (848 pcs), providing immediate procurement availability compared to the obsolete FR501-AP.

Frequently Asked Questions (FAQ)

Q: Can FR501GP-AP be used as a direct replacement for FR501-AP in existing designs?

A: Yes. FR501GP-AP is electrically and mechanically identical to FR501-AP across all specified parameters. Direct substitution is valid without circuit redesign or board layout modification.

Q: Are there any differences in electrical performance between FR501-AP and FR501GP-AP?

A: No. Both parts share identical specifications for reverse voltage (50 V), forward current (5 A), forward voltage drop (1.35 V @ 5 A), reverse recovery time (150 ns), reverse leakage current (10 µA @ 50 V), and junction capacitance (65 pF @ 4V, 1MHz).

Q: Why is FR501-AP listed as obsolete?

A: FR501-AP has been discontinued by the manufacturer. FR501GP-AP is the active production equivalent and should be used for all new procurement and design activities.

Q: Is the DO-201AD package identical between both parts?

A: Yes. Both FR501-AP and FR501GP-AP use the DO-201AD axial through-hole package. PCB footprints and mechanical mounting are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN and HTSUS classifications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across a junction temperature range of -55°C to 150°C.

Q: Are there any supply chain advantages to using FR501GP-AP over FR501-AP?

A: Yes. FR501GP-AP is actively manufactured and currently in stock (848 pcs), whereas FR501-AP is obsolete with limited remaining inventory (1003 pcs). FR501GP-AP provides superior long-term supply chain continuity.
