Substitute Part Grouping Explanation

Substitution is strictly determined by these parameters:

Schottky technology
Maximum DC reverse voltage (Vr): 40 V
Average rectified current (Io): 3A
Maximum forward voltage (Vf) at rated current
Reverse leakage current at Vr
Recovery speed
Surface mount type and package: DO-214AC (SMA) or mechanically/electrically equivalent
Compliance and certification: ROHS3, REACH, ECCN, MSL

Parts meeting all or closely matching these criteria are grouped as direct, parametric equivalents, or similar substitutes.

Engineering Selection Recommendations

Component selection must be based on product status and compliance. The main part, CD214A-B340LF, is Obsolete; parts with an Active status are preferred for designs requiring continued availability. All listed substitutes are ROHS3 Compliant and meet moisture sensitivity level requirements, supporting compliance with regulatory standards.

Frequently Asked Questions (FAQ)

Q: Which parameters must match to ensure a direct substitute for CD214A-B340LF?
A: Substitute parts must match Schottky technology, 40V maximum reverse voltage, 3A average rectified current, forward voltage at rated current, reverse leakage current at Vr, recovery speed, and have a compatible surface-mount package such as DO-214AC (SMA).

Q: Is package compatibility required for substitution?
A: Yes, mechanical compatibility in package type (DO-214AC, SMA) or equivalent surface-mount formats is required for interchangeability.

Q: Can parts with different forward voltage or reverse leakage ratings be substituted?
A: Only parts with parameters within the range specified for CD214A-B340LF can be substituted as equivalents.

Q: How does product status affect substitute selection?
A: Active status substitutes are required to maintain supply chain continuity when the main part is obsolete.

Q: Is RoHS3 compliance necessary for substitution?
A: All substitutes listed are ROHS3 Compliant, matching the main part’s compliance.

Q: Are parametric equivalents from other manufacturers acceptable?
A: Parametric equivalents are accepted if they strictly match the key parameters listed for CD214A-B340LF.

Q: Are moisture sensitivity level (MSL) and REACH/ECCN factors considered in selection?
A: Yes, substitutes provided reflect MSL 1 and comparable regulatory status for direct substitution.
