No successor part number is provided in the available documentation, so a direct pin-compatible replacement is not confirmed from the original manufacturer. For existing designs already using this oscillator, independent distribution channels can source remaining stock on a quoted-to-order basis.

User-Programmable Frequency – Plan for Programming
This part ships as a blank device (user must program) — the target frequency between 1 MHz and 80 MHz is set by the buyer during manufacturing, not at the factory. Factor in a programming step and the required Microchip programming tooling when planning the assembly flow.
