FR506-TP Equivalent & Substitute Parts

Part Overview

The FR506-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 5 A average rectified current in a DO-201AD axial through-hole package. This part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support, maintenance, and production continuity. The FR506-TP operates across a junction temperature range of -55°C to 150°C and features fast recovery characteristics with a reverse recovery time of 500 ns, suitable for standard rectification applications requiring moderate voltage and current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR506-TP is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part FR506GP-TP maintains identical specifications for voltage rating (800 V DC reverse), current rating (5 A average rectified), forward voltage drop (1.35 V @ 5 A), reverse recovery time (500 ns), reverse leakage current (10 µA @ 800 V), junction capacitance (65 pF @ 4V, 1MHz), and package type (DO-201AD axial through-hole). Both parts operate across the same temperature range (-55°C to 150°C) and employ standard rectifier technology with fast recovery characteristics.

The primary distinction between the main part and its substitute is packaging format and product status. The FR506-TP is supplied in standard packaging and carries obsolete status, while FR506GP-TP is supplied in Tape & Reel (TR) format and maintains active product status. This substitution is valid for applications where the electrical performance and mechanical fit are the determining factors, with packaging format adjustment required during procurement and assembly planning.

Parameter Comparison

Engineering Selection Recommendations

The FR506GP-TP is the direct electrical and mechanical equivalent of the FR506-TP. Selection of FR506GP-TP is appropriate for new designs, production restocking, and replacement applications where the FR506-TP is no longer available due to its obsolete status. Both parts are ROHS3 compliant and carry identical electrical specifications, ensuring functional interchangeability in circuit applications.

The FR506GP-TP maintains active product status with Micro Commercial Co, providing supply chain continuity and long-term availability. The Tape & Reel (TR) packaging format of FR506GP-TP is standard for high-volume manufacturing and automated assembly processes, whereas the FR506-TP standard packaging may be more suitable for manual assembly or low-volume applications. Procurement planning should account for packaging format differences when transitioning from FR506-TP to FR506GP-TP.

Both parts carry REACH Unaffected or equivalent compliance status and are classified under ECCN EAR99 with HTSUS code 8541.10.0080, meeting regulatory requirements for general commercial distribution.

Frequently Asked Questions (FAQ)

Q: Can FR506GP-TP be used as a direct replacement for FR506-TP in existing circuit designs?

A: Yes. The FR506GP-TP is electrically and mechanically identical to the FR506-TP across all specified parameters, including voltage rating, current rating, forward voltage drop, reverse recovery time, and package type (DO-201AD axial through-hole). Direct substitution is valid for circuit applications without design modification.

Q: What is the difference between FR506-TP and FR506GP-TP?

A: The primary differences are product status and packaging format. The FR506-TP is obsolete and supplied in standard packaging, while FR506GP-TP is active and supplied in Tape & Reel (TR) format. All electrical and mechanical specifications are identical.

Q: Does the Tape & Reel (TR) packaging of FR506GP-TP affect circuit performance?

A: No. Tape & Reel packaging is a supply and assembly format only. The diode component itself is identical to standard packaging. TR format is optimized for automated pick-and-place assembly equipment and high-volume production environments.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited). Both carry ECCN EAR99 classification and HTSUS code 8541.10.0080. The FR506GP-TP includes REACH Unaffected status. No functional compliance differences exist.

Q: What is the reverse recovery time specification, and why is it important?

A: Both parts have a reverse recovery time (trr) of 500 ns, classifying them as fast recovery diodes. This parameter defines the time required for the diode to switch from forward conduction to reverse blocking state. Fast recovery characteristics are essential for switching power supplies and high-frequency rectification applications.

Q: Can FR506GP-TP be used in applications rated for -55°C to 150°C junction temperature?

A: Yes. The FR506GP-TP is rated for the same operating temperature range (-55°C to 150°C) as the FR506-TP, ensuring equivalent thermal performance across all specified operating conditions.

Q: Is the 5 A current rating the peak or average rectified current?

A: The 5 A specification is the average rectified current (Io), not peak current. This is the continuous DC current the diode can conduct under specified conditions. Circuit design must account for this rating when calculating thermal dissipation and component stress.
