Equivalent & Substitute Parts Reference: FR3DB-TP

Part Overview

Manufacturer part number FR3DB-TP, produced by Micro Commercial Co, is classified within the Diodes, Rectifiers category. This device is a surface-mount, fast-recovery diode designed for 200 V DC reverse voltage and 3A average rectified current ratings, using the DO-214AA (SMB) package. Its product status is listed as "Not For New Designs," indicating it is being phased out and not recommended for incorporation into new products or designs. Therefore, identifying strictly compatible alternative models within the same electrical and mechanical specifications is necessary for both design continuity and supply chain assurance.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic is strictly defined by the matching or closely aligned electrical and mechanical parameters as documented. Key parameters for valid equivalency include: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), Voltage - Forward (Vf) (Max) @ If, Reverse Recovery Time (trr), Speed, Current - Reverse Leakage @ Vr, Capacitance @ Vr, Mounting Type, Package / Case, Supplier Device Package, and Operating Temperature - Junction. Only diodes within the DO-214AA (SMB) package that fulfill these thresholds and requirements can be considered suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

FR3DB-TP is designated as "Not For New Designs." The substitute part ES2D-M3/52T retains an active status. Both parts share equivalent environmental compliance, marked as REACH Unaffected, and identical ECCN and HTSUS code designations. Engineering selection between these should be based on current product status and compliance certifications as provided.

Frequently Asked Questions (FAQ)

Q: What key parameters must match when selecting a substitute for FR3DB-TP in the Diodes, Rectifiers category?
A: Required parameters for selection include Voltage - DC Reverse (Vr), Current - Average Rectified (Io), Voltage - Forward (Vf), Reverse Recovery Time (trr), Speed, Current - Reverse Leakage, Capacitance, Mounting Type, Package, and Operating Temperature.

Q: Is package compatibility important in substituting DO-214AA (SMB) diodes?
A: Yes, only substitutes in the DO-214AA (SMB) package and supplier device package may be considered compatible for direct replacement.

Q: Does the product status affect substitution suitability?
A: Yes, parts listed as "Not For New Designs" require alternatives with "Active" status for ongoing use in new designs.

Q: Are environmental compliance certifications relevant in substitution?
A: Environmental certifications such as REACH status must be equivalent for regulatory compliance continuity.

Q: Are there differences in ratings such as current and voltage between FR3DB-TP and ES2D-M3/52T?
A: Both have the same maximum reverse voltage (200 V), but the main part has a higher maximum average rectified current (3 A) compared to the substitute (2 A), which must be considered in applications where current rating is critical.
