FR2K-TP Equivalent & Substitute Parts

Part Overview

The FR2K-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design requirements and procurement needs. Active alternatives with identical or enhanced electrical characteristics are available from the same manufacturer and qualified suppliers.

Substitute Part Grouping Explanation

Substitution of the FR2K-TP is determined by equivalence in the following critical parameters:

Voltage Rating: 800 V DC reverse voltage (Vr) maximum
Current Rating: 2 A average rectified current (Io) minimum
Package Type: DO-214AA (SMB) surface mount configuration
Temperature Range: Operating junction temperature -50°C to 150°C
Compliance: ROHS3 compliance and moisture sensitivity level 1

Substitute parts are classified into two categories:

Direct Equivalent (FR2K-LTP): Identical electrical specifications and ratings from the same manufacturer base product series (FR2K). Differs only in packaging format (Tape & Reel) and product status (Active).

Similar Substitute (S3KBH): Meets or exceeds voltage and package requirements with higher current rating (3 A). Introduces differences in recovery speed, reverse leakage, and temperature range. Includes automotive qualification (AEC-Q101).

Engineering Selection Recommendations

FR2K-LTP is the primary substitute for FR2K-TP applications. This part maintains identical electrical specifications and operating parameters while offering active product status and improved availability. The FR2K-LTP differs only in packaging format (Tape & Reel versus bulk) and represents a direct functional replacement. Both parts share the same base product number (FR2K) and comply with ROHS3 requirements.

S3KBH serves as an alternative substitute where circuit design permits higher current capacity (3 A versus 2 A). This part is qualified to automotive standards (AEC-Q101) and extends the lower operating temperature limit to -55°C. The S3KBH exhibits slower reverse recovery time (1.5 µs versus 500 ns) and higher reverse leakage current (10 µA versus 5 µA), which may affect performance in high-frequency switching applications. Selection of S3KBH requires confirmation that the application circuit tolerates these electrical differences.

Both substitute parts maintain DO-214AA (SMB) package compatibility, ROHS3 compliance, and moisture sensitivity level 1 classification.

Frequently Asked Questions (FAQ)

Q: Can FR2K-LTP directly replace FR2K-TP without circuit modification?

A: Yes. The FR2K-LTP maintains identical voltage rating (800 V), current rating (2 A), reverse recovery time (500 ns), reverse leakage current (5 µA @ 800 V), and operating temperature range (-50°C to 150°C). The only difference is packaging format (Tape & Reel). No circuit modification is required.

Q: What are the limitations of using S3KBH as a substitute?

A: The S3KBH introduces three electrical differences: reverse recovery time increases from 500 ns to 1.5 µs, reverse leakage current increases from 5 µA to 10 µA at 800 V, and the lower operating temperature extends to -55°C. These differences are acceptable in applications where switching speed is not critical and leakage current tolerance is adequate. The higher current rating (3 A) provides design margin but does not affect compatibility in 2 A circuits.

Q: Are all substitute parts available in the same DO-214AA (SMB) package?

A: Yes. FR2K-TP, FR2K-LTP, and S3KBH are all manufactured in the DO-214AA (SMB) surface mount package. No PCB layout or footprint changes are required when substituting between these parts.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant and carry moisture sensitivity level 1 (unlimited). The S3KBH additionally holds AEC-Q101 automotive qualification. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Why is FR2K-TP classified as obsolete?

A: FR2K-TP is marked obsolete by the manufacturer. The FR2K-LTP, sharing the same base product number (FR2K), represents the active continuation of this product line and is the recommended replacement for procurement and new designs.
