FR602-TP Equivalent & Substitute Parts

Part Overview

The FR602-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100V DC reverse voltage and 6A average rectified current in an R-6 axial through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing design support and procurement continuity. The FR602-TP operates across a junction temperature range of -55°C to 150°C and features fast recovery characteristics with a reverse recovery time of 150 nanoseconds.

Substitute Part Grouping Explanation

Substitution of the FR602-TP is determined by strict equivalence across the following critical parameters:

Voltage Rating: DC reverse voltage of 100V maximum
Current Rating: Average rectified current of 6A
Forward Voltage Drop: 1.3V maximum at 6A forward current
Recovery Characteristics: Fast recovery classification with 150ns reverse recovery time
Reverse Leakage: 10µA maximum at 100V reverse bias
Package Configuration: R-6 axial through-hole form factor

Engineering Selection Recommendations

The FR602T-G from Comchip Technology is the direct parametric equivalent for the obsolete FR602-TP. Both components share identical electrical ratings across voltage, current, forward drop, and recovery characteristics. The FR602T-G maintains active product status, ensuring long-term availability and supply chain continuity.

The capacitance specification of the FR602T-G (100pF @ 4V, 1MHz) is lower than the FR602-TP (150pF @ 4V, 1MHz). This difference does not affect substitution eligibility for standard rectification applications, as capacitance at reverse bias is not a primary selection criterion for general-purpose rectifier diodes in most circuit topologies.

Both components carry ROHS3 compliance certification and EAR99 export classification, meeting regulatory requirements for industrial and commercial applications. The FR602T-G is supplied in Tape & Reel packaging format, whereas the FR602-TP was available in bulk form. This packaging difference reflects standard industry practice for active components and does not affect electrical performance or mechanical compatibility in through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the FR602T-G replace the FR602-TP in existing designs?

A: Yes. The FR602T-G meets all electrical and mechanical specifications of the FR602-TP. Both components are rated for 100V reverse voltage, 6A average rectified current, and feature identical forward voltage drop and recovery time characteristics. The R-6 axial through-hole package is identical between both parts.

Q: What is the significance of the capacitance difference between these parts?

A: The FR602T-G has a capacitance rating of 100pF compared to the FR602-TP at 150pF, both measured at 4V and 1MHz. For general-purpose rectification applications, this difference is not functionally significant. Capacitance at reverse bias does not affect rectification performance in standard power supply and signal conditioning circuits.

Q: Why is the FR602-TP listed as obsolete?

A: The FR602-TP is classified as obsolete by the original manufacturer, Micro Commercial Co. The FR602T-G from Comchip Technology is the active equivalent, ensuring continued availability for new designs and replacement applications.

Q: Are there packaging considerations when substituting these parts?

A: The FR602-TP was supplied in bulk packaging, while the FR602T-G is supplied in Tape & Reel (TR) format. Both use the same R-6 axial through-hole package configuration. Tape & Reel packaging is standard for active components and does not affect electrical performance or mechanical fit in through-hole PCB applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the FR602-TP and FR602T-G are ROHS3 compliant and classified under EAR99 export regulations. They meet identical regulatory requirements for industrial and commercial applications.

Q: What is the operating temperature range for these diodes?

A: Both components operate across a junction temperature range of -55°C to 150°C, providing equivalent thermal performance across industrial and extended temperature applications.
