Engineering Selection Recommendations

When selecting an equivalent or substitute for the Bourns Inc. CD214A-B180LF, consider product lifecycle status and environmental compliance:

CD214A-B1100R, B180-13-F, and B170-13-F are classified as Active and ROHS3 Compliant with MSL 1 ratings, providing ongoing availability with similar or extended electrical parameters.
SS18 and SS18-LTP are Not For New Designs. These parts maintain comparable electrical and mechanical characteristics, but their product status should be evaluated regarding supply chain and design-in strategies.
REACH and RoHS compliance differ between models; CD214A-B180LF and CD214A-B1100R are REACH Affected, while B180-13-F, B170-13-F, SS18, and SS18-LTP are REACH Unaffected.
Package, MSL, and mounting style are consistent across parts except for the 2-SMD, No Lead variant in CD214A-B1100R, which should be assessed for mechanical fit.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for selecting a substitute for CD214A-B180LF?
A1: Substitutes must match on key parameters including diode type (Schottky), maximum DC reverse voltage, average rectified current, forward voltage characteristics, reverse leakage current, speed, mounting type, package/footprint, RoHS and REACH status, and operating temperature range.

Q2: Are the packages and footprints of substitute parts always identical?
A2: Most substitutes share the DO-214AC (SMA) package. CD214A-B1100R utilizes a 2-SMD, No Lead package, requiring verification of PCB footprint compatibility.

Q3: How does product status affect selection?
A3: Prefer Active or ongoing production models for long-term supply assurance. Parts Not For New Designs may have limited future availability.

Q4: Are all listed substitutes compliant with RoHS and MSL requirements?
A4: All substitutes are ROHS3 Compliant and rated MSL 1 (Unlimited). REACH status varies and should be matched to regulatory requirements of the final application.

Q5: Are there performance differences beyond basic parameters?
A5: Substitutes provided match all explicitly listed key parameters including voltage, current, Vf, reverse leakage, speed, and basic capacitance. Only parameters provided were used for comparison.
