CDLL485B Equivalent & Substitute Parts Reference

Part Overview

CDLL485B is a general purpose rectifier diode from Microchip Technology, categorized under Diodes, Rectifiers. It features a 180 V maximum DC reverse voltage, 200 mA average rectified current, and a DO-213AA surface-mount package. The part is currently active and available in new original inventory. Engineering teams may need to identify alternative or parametric equivalent models for reasons including inventory management, lead time optimization, or system compatibility—to ensure uninterrupted design and production flow.

Key Parameters

Substitute Part Grouping Explanation

Substitutes for the CDLL485B are selected strictly by matching the following key parameters: maximum DC reverse voltage (Vr), average rectified current (Io), voltage forward (Vf) at specified current, reverse leakage current at maximum Vr, package/case type, mounting style, operating temperature range, and compliance status (RoHS, REACH, MSL). Only parts that exactly match these electrical and mechanical attributes, as explicitly listed, are eligible as direct substitutes in the specified product category.

Parameter Comparison

Engineering Selection Recommendations

Both CDLL485B and the parametric equivalent CDLL5195 are active and share identical compliance attributes, including RoHS non-compliance, REACH unaffected status, and an MSL rating of 1 (unlimited). Selection between these models can be made based exclusively on inventory, lead time, or supply chain factors, as their regulatory status and certifications are equivalent.

Frequently Asked Questions (FAQ)

Q1: What are the precise criteria for substituting CDLL485B with another part?
A1: Substitution requires an identical match for maximum DC reverse voltage, average rectified current, forward voltage at the specified test current, reverse leakage current at specified voltage, package/case, mounting type, and regulatory/compliance status.

Q2: Are CDLL485B and CDLL5195 mechanically and electrically identical?
A2: Both parts share the same key electrical parameters and mechanical DO-213AA surface mount package based on the provided data.

Q3: Does the RoHS or REACH status affect substitution for regulatory-constrained applications?
A3: Both parts are RoHS non-compliant and REACH unaffected, so there is no difference in compliance impacts for substitution based on these standards.

Q4: Is any difference in Moisture Sensitivity Level (MSL) relevant in this case?
A4: No, both diodes have an MSL rating of 1 (unlimited), indicating identical moisture sensitivity handling requirements.

Q5: Are there considerations regarding inventory or stock when selecting between CDLL485B and its substitute?
A5: Selection may be based on inventory availability as both parts are otherwise functionally and mechanically equivalent per the provided specifications.
