FR606GP-TP Equivalent & Substitute Parts

Part Overview

The FR606GP-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 800V DC reverse voltage and 6A average rectified current in an R-6 axial through-hole package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent substitute parts is necessary for maintenance, repair, and legacy system support where continued availability of the original part number cannot be guaranteed.

Substitute Part Grouping Explanation

Substitution of the FR606GP-TP is determined by strict equivalence across the following critical parameters:

Voltage Rating: DC reverse voltage must equal 800V
Current Rating: Average rectified current must equal 6A
Forward Voltage Drop: Maximum forward voltage at rated current must equal 1.3V @ 6A
Recovery Characteristics: Reverse recovery time must equal 500ns with fast recovery classification
Reverse Leakage: Maximum reverse leakage current must equal 10µA @ 800V
Package Configuration: Through-hole mounting in R-6 axial package required
Temperature Range: Operating junction temperature range must span -55°C to 150°C
Technology Type: Standard rectifier diode technology

The FR606T-G manufactured by Comchip Technology meets all these criteria and qualifies as a parametric equivalent substitute.

Engineering Selection Recommendations

The FR606T-G is a direct parametric equivalent to the FR606GP-TP across all critical electrical and mechanical specifications. The substitute part is manufactured by Comchip Technology and maintains active product status, ensuring continued availability and supply chain reliability.

Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications, confirming regulatory and trade compliance equivalence. The FR606T-G operates within the same temperature range and maintains identical voltage, current, and recovery time specifications required for circuit-level compatibility.

The minor difference in capacitance (100pF versus 150pF at 4V, 1MHz) does not affect substitution eligibility, as this parameter remains within acceptable tolerance for general-purpose rectifier applications and does not alter the functional performance in standard power supply and rectification circuits.

Selection of the FR606T-G is appropriate for replacement applications where the FR606GP-TP is no longer available due to end-of-life status.

Frequently Asked Questions (FAQ)

Q: Can the FR606T-G replace the FR606GP-TP in existing circuit designs?

A: Yes. The FR606T-G meets all electrical and mechanical specifications of the FR606GP-TP, including voltage rating, current rating, forward voltage drop, recovery time, reverse leakage, and package configuration. Direct substitution is supported without circuit modification.

Q: What is the significance of the "Not For New Designs" status on the FR606GP-TP?

A: This designation indicates the part has reached end-of-life and is no longer recommended for new product development. Existing inventory may be available, but long-term supply cannot be guaranteed. The FR606T-G, with active product status, provides a sustainable alternative for both legacy support and new applications.

Q: Are there differences in thermal performance between these parts?

A: Both parts operate across the identical junction temperature range of -55°C to 150°C. No thermal performance differences exist between the FR606GP-TP and FR606T-G.

Q: Does the capacitance difference affect circuit operation?

A: The capacitance difference (150pF versus 100pF) is minor and does not impact substitution suitability for general-purpose rectifier applications. Both values are within acceptable ranges for standard power supply circuits.

Q: Are both parts RoHS compliant?

A: Yes. Both the FR606GP-TP and FR606T-G are ROHS3 compliant, confirming equivalent environmental and regulatory status.

Q: Can the FR606T-G be used in high-frequency switching applications?

A: Both parts are classified as fast recovery diodes with 500ns reverse recovery time and are suitable for applications requiring recovery speeds in this range. Application suitability depends on specific circuit requirements beyond the scope of parametric equivalence.

Q: Is the R-6 axial package identical between manufacturers?

A: Yes. Both parts use the R-6 axial through-hole package, ensuring mechanical and electrical compatibility in PCB layouts and circuit board designs.
