FR6DR02 Equivalent & Substitute Parts Reference

Part Overview

GeneSiC Semiconductor FR6DR02 is a fast recovery, general-purpose reverse polarity diode in the DO-203AA (DO-4, stud) package. It is rated for 200 V maximum DC reverse voltage and 6A average rectified current with a chassis, stud mount. The product is currently active with RoHS compliance. Sourcing equivalent and substitute parts is necessary for ensuring continuous supply, qualifying alternate vendors, or aligning with specific compliance needs while maintaining performance and form factor.

Substitute Part Grouping Explanation

Substitute and equivalent part selection for diodes in this category is strictly based on the following provided parameters:

Maximum DC reverse voltage (Vr)
Average rectified current (Io)
Forward voltage (Vf) at specified current
Reverse recovery time (trr)
Mounting style and package (DO-203AA, DO-4, Stud)
Operating junction temperature range
Product status
RoHS/compliance status

These ensure functional equivalence and mechanical compatibility in replacement scenarios.

Engineering Selection Recommendations

The main part, FR6DR02, is active and RoHS compliant. The parametric equivalent, 1N3881R, is also active but is RoHS non-compliant. Selection should be based on product status and required compliance. If RoHS compliance is mandatory, FR6DR02 is appropriate. For applications without RoHS restriction, 1N3881R offers a substitute with common electrical and mechanical characteristics.

Frequently Asked Questions (FAQ)

Q1. What determines substitution compatibility for FR6DR02 equivalents?
Compatibility is determined by matching voltage rating, current rating, forward voltage, reverse recovery time, mounting type, package, and operating temperature range.

Q2. Are the package and mounting type identical between FR6DR02 and 1N3881R?
Both devices feature stud mount in the DO-203AA, DO-4 package, ensuring mechanical interchangeability.

Q3. Is RoHS compliance different for FR6DR02 and its substitute?
FR6DR02 is RoHS compliant, while 1N3881R is RoHS non-compliant. Compliance should be verified based on application requirements.

Q4. Do electrical parameters differ between FR6DR02 and 1N3881R?
Maximum DC Reverse Voltage, Average Rectified Current, and Reverse Recovery Time are matched. Forward voltage is specified at different currents (1.4 V @ 6A for FR6DR02, 1.4 V @ 20A for 1N3881R).

Q5. Is the substitute part active and readily available?
Both FR6DR02 and 1N3881R are active, with inventory reported in bulk packaging.

Q6. Is there a difference in operating temperature specification?
FR6DR02 has an operating temperature range of -65°C ~ 150°C, while 1N3881R supports -65°C ~ 175°C, both suitable for high-reliability environments.
