| FFF Compatibility | Both devices are unidirectional axial-leaded TVS diodes in the DO-201 / DO-201AA package with the same footprint and installation polarity.Direct standard axial form factor with identical body dimensions and wire lead specifications.The standoff voltage is 5.8V (vs 5.0V), breakdown voltage is 6.45V (vs 6.0V), and max clamping voltage is 10.5V (vs 9.4V), which represents a minor degradation in tight-tolerance 5V line clamping. | Identical unidirectional axial-leaded diode outline with same pin configuration (cathode band indication).Exact physical dimensions of the DO-201 package.Standoff voltage is 5.8V (vs 5.0V) and clamping voltage is 10.5V (vs 9.4V), which may allow slightly higher transient voltages onto protected lines. | ||
 AI Summary | ICTE-5 by Littelfuse: ESD Protection Diodes / TVS Diodes. | This is the manufacturer's closest active through-hole alternative in the same DO-201 package. While it shifts the standoff and clamping voltages slightly higher, it remains the standard drop-in industry replacement.
| Vishay's equivalent to the 1.5KE6.8A series is a highly reliable, active through-hole replacement recommended by major distributors for obsolete 5V low-clamping TVS diodes.

You searched one part. Parter watches your whole BOM.
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-5 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-5 are the 1.5KE6.8A (Littelfuse Inc.) and the 1.5KE6.8A-E3/54 (Vishay Semiconductors), out of 5 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-5 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-5 (Littelfuse) is a part in the ESD Protection Diodes / TVS Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
