| FFF Compatibility | Both the ICTE-15 and LCE15A are 2-pin axial through-hole components with identical anode and cathode assignments.The DO-201 package is a direct physical replacement for the DO-201AD package with matching overall dimensions.The LCE15A provides active low-capacitance TVS protection with matching 15V standoff. However, the clamping voltage is higher (24.4V vs. 20.6V) and the minimum breakdown voltage is slightly lower (16.7V vs. 17.6V). | The 1.5KE18A utilizes the same 2-pin axial through-hole configuration.The DO-201AA/DO-27 package directly matches the physical footprint of the original DO-201AD.Features a slightly higher reverse standoff voltage (15.3V vs. 15V) and breakdown voltage (17.1V vs. 17.6V), but has a significantly higher clamping voltage of 25.2V compared to the ICTE-15's 20.6V. | ||
 AI Summary | ICTE-15 by Littelfuse: 20.6V Clamp Ipp Tvs Diode Through Hole DO-201AD. | The LCE15A is an active low-capacitance TVS diode that perfectly matches the 15V reverse standoff voltage of the obsolete ICTE-15. It utilizes the same axial DO-201 package, providing a direct drop-in mechanical replacement. Due to its modern design, it has a slightly higher clamping voltage of 24.4V, which must be evaluated against the maximum voltage limit of the protected IC.
| The 1.5KE18A is a widely used general-purpose TVS diode that serves as a highly robust replacement. It offers a slightly higher reverse standoff of 15.3V, ensuring it will not clip normal signal voltages on a 15V line. However, it exhibits a higher peak clamping voltage of 25.2V compared to the specialized low-clamping factor of the ICTE-15.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Littelfuse ICTE-15 is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Littelfuse ICTE-15 are the LCE15A (Littelfuse Inc.) and the 1.5KE18A (Littelfuse Inc.), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the ICTE-15 are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The ICTE-15 (Littelfuse) is a part in the Transient Voltage Suppressors (TVS) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
