ASFL-48.000MHZ Equivalent & Substitute Parts

Part Overview

The ASFL-48.000MHZ is a 48 MHz oscillator manufactured by Abracon LLC. This part is classified as Obsolete, necessitating identification of active equivalent components for continued system support and new designs. The oscillator functions as a standard XO (crystal oscillator) providing timing signals in electronic applications requiring 48 MHz frequency reference.

Due to its obsolete status, the ASFL-48.000MHZ requires substitution with active production equivalents that maintain functional and electrical compatibility with the original design specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASFL-48.000MHZ is based on the following critical parameters that must align between the original and substitute component:

Frequency Match: The substitute part must operate at 48.000 MHz to maintain system timing requirements.

Manufacturer Continuity: Abracon LLC manufactures both the original and substitute part, ensuring design consistency and supply chain reliability.

Compliance Alignment: Both parts must maintain ROHS3 compliance and REACH Unaffected status to satisfy regulatory requirements in target markets.

Moisture Sensitivity: MSL rating of 1 (Unlimited) must be preserved to ensure handling and storage compatibility with existing manufacturing processes.

The ASFL1-48.000MHZ-EC-T qualifies as a direct substitute based on these parameters. This part is in Active production status, addressing the obsolescence of the original component.
