Engineering Selection Recommendations

The RB085B-90TL is listed as Obsolete. Substitute selection is based strictly on equivalent electrical, mechanical, and regulatory parameters. All substitute parts listed are ROHS3 Compliant and share the same Mounting Type, Package/Case, and Regulatory Status as the original part. Only parts listed as Active or with matching compliance status are considered valid substitutes per the provided data.

Frequently Asked Questions (FAQ)

Q1: How are substitute parts for RB085B-90TL selected?
A1: Substitute parts are selected strictly based on matching diode configuration, Schottky technology, maximum DC reverse voltage, average rectified current, forward voltage, reverse leakage, speed, maximum junction temperature, mounting type, package/case, and RoHS compliance.

Q2: Is the package and footprint the same for all substitutes?
A2: All listed substitutes use the TO-252-3, DPAK (2 Leads + Tab), SC-63 surface mount package for direct mechanical compatibility.

Q3: Is regulatory compliance maintained across substitutes?
A3: All substitute parts provided are ROHS3 Compliant and REACH Unaffected, ensuring regulatory continuity.

Q4: Can any substitute be used without electrical derating?
A4: Substitute parts must have electrical parameters equal to or exceeding those of the original (e.g., voltage, current ratings) to ensure functional compatibility as per the provided specifications.

Q5: Are any of the substitutes currently in production?
A5: RB085BM-90TL, RB085BGE-90TL, and MBRD10100CT are listed as Active, making them suitable for ongoing procurement according to the given part data.
