CD216A-B140LF Equivalent & Substitute Parts Reference

Part Overview

CD216A-B140LF is a surface mount Schottky diode specified for 40 V reverse voltage and 1A average rectified current, offered in a DO-216AA package by Bourns Inc. This device features fast recovery speed (≤500ns), low forward voltage, and ROHS3 compliance. As indicated, CD216A-B140LF is classified as obsolete, making it necessary for engineers to identify alternative or parametric equivalent parts that satisfy identical electrical, mechanical, and compliance criteria for continuity in diode, rectifier-based designs.

Substitute Part Grouping Explanation

Substitutes are identified by matching the following parameters:

Technology (Schottky)
Maximum DC reverse voltage (40 V)
Average rectified current (1A)
Maximum forward voltage at rated current
Recovery speed (Fast ≤500ns, >200mA Io)
Reverse leakage current threshold
Surface mount compatibility
Package/case type is considered for mechanical interchangeability
RoHS compliance
Operating junction temperature range

Parts are grouped as either parametric equivalents (with identical electrical performance and physical package) or as similar functional alternatives (with minor differences in package type or detailed electrical ratings).

Engineering Selection Recommendations

Selection of substitute parts for CD216A-B140LF is based on matching electrical parameters and ensuring regulatory compliance. Only components that are ROHS3 compliant, rated for -55°C to 125°C junction temperature, and supplied as surface mount devices are considered equivalent. Given the obsolete status of CD216A-B140LF, eligible substitutes include MBRM140T1G, MBRM140T3G, and NRVBM140T1G, which fully match case type (DO-216AA), and CD123D-B140R, which matches all principal electrical criteria but differs in package structure. All listed substitutes are documented with active product status and unrestricted MSL.

Frequently Asked Questions (FAQ)

Q1: How are equivalents for the Bourns CD216A-B140LF selected?
A1: Engineering equivalents are selected by verifying matching Schottky technology, 40 V reverse voltage, 1A average rectified current, fast recovery performance, maximum forward voltage, packaging style, and regulatory compliance parameters.

Q2: Are substitute diodes required to have the same package as CD216A-B140LF?
A2: Substitute diodes with DO-216AA package (MBRM140T1G, MBRM140T3G, NRVBM140T1G) maintain mechanical compatibility. CD123D-B140R provides an alternative case (Chip, Concave Terminals) while adhering to the same electrical ratings.

Q3: What is the significance of ROHS3 compliance in selection?
A3: ROHS3 compliance ensures environmental and material regulatory requirements are met for all listed equivalents, consistent with CD216A-B140LF.

Q4: Do electrical parameters affect direct substitution?
A4: Only substitutes that strictly match Schottky technology, voltage, current, forward voltage, speed, and leakage ratings are considered direct electrical equivalents for CD216A-B140LF.

Q5: What should be considered regarding moisture sensitivity and temperature range?
A5: All listed equivalents feature MSL 1 rating and identical -55°C ~ 125°C operating junction temperature ranges, ensuring interchangeability in standard surface mount applications.

Q6: Is the obsolete status of CD216A-B140LF the primary reason for substitution?
A6: Yes, the obsolete product classification necessitates sourcing active parts with identical electrical and mechanical parameters.
