Product details

Lifecycle reality — obsolete, but sourced here

Littelfuse lists the 1.5KE9.1C as obsolete. No official successor order code is recorded — the 1.5KE series is broad, and replacement requires matching the breakdown voltage (8.17 V min) and bidirectional configuration. Available through independent distribution on a quoted-to-order basis. Reel quantities (Tape & Reel, TR) are typical; date codes and lot traceability confirmed at RFQ. This is a last-time-buy / surplus channel — no manufacturer lead time applies.

Frequently asked questions

How can I order the 1.5KE9.1C or check stock?

The 1.5KE9.1C is obsolete but sourced through independent distribution. Submit an RFQ — current pricing, reel quantities, and date codes are confirmed at quote time. No stock-holding claim; availability verified per inquiry.

What compliance documentation does Littelfuse provide for the 1.5KE9.1C?

The evidence does not specify RoHS, REACH, UL, or IEC certifications for this specific order code. Typical for the 1.5KE series, Littelfuse publishes a datasheet with electrical characteristics and package dimensions; compliance status should be verified against the manufacturer's official documentation.
