ASFL-25.000MHZ-LC Equivalent & Substitute Parts

Part Overview

The ASFL-25.000MHZ-LC is a 25 MHz oscillator manufactured by Abracon LLC. This component is classified as obsolete and is no longer in active production. The ASFL-25.000MHZ-LC remains available in limited inventory (709 pieces) as new original stock. Due to its obsolete status, identifying equivalent substitute parts is necessary for ongoing system maintenance, repair, and new design implementations where this frequency and oscillator type are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASFL-25.000MHZ-LC is determined by the following critical parameters:

Frequency Match: The substitute part must operate at 25.000 MHz to maintain system timing requirements and signal integrity.

Oscillator Type: Both the main part and substitute must function as XO (Standard) oscillators to ensure equivalent operational characteristics.

Manufacturer Consistency: Abracon LLC manufactures both the obsolete part and its substitute, ensuring design continuity and reliability standards.

Compliance Certifications: Both parts maintain ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components.

Moisture Sensitivity: Both parts share MSL 1 (Unlimited) rating, indicating identical moisture handling and storage requirements.

The ASFL1-25.000MHZ-L-T is identified as the direct substitute for the ASFL-25.000MHZ-LC based on these matching parameters.

Engineering Selection Recommendations

The ASFL1-25.000MHZ-L-T serves as the direct substitute for the obsolete ASFL-25.000MHZ-LC. Selection of this substitute is supported by the following factors:

Product Status: The ASFL1-25.000MHZ-L-T maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete ASFL-25.000MHZ-LC.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements without modification to existing designs.

Moisture Handling: Identical MSL 1 (Unlimited) ratings ensure equivalent moisture sensitivity characteristics, requiring no changes to packaging, storage, or handling procedures.

Inventory Availability: The substitute part is available in significantly higher quantities (17736 pieces versus 709 pieces), providing improved supply security for production and maintenance applications.

Manufacturer Continuity: Both parts originate from Abracon LLC, maintaining design philosophy and quality standards across the substitution.

Frequently Asked Questions (FAQ)

Q: Can the ASFL1-25.000MHZ-L-T directly replace the ASFL-25.000MHZ-LC in existing designs?

A: The ASFL1-25.000MHZ-L-T is the designated substitute for the ASFL-25.000MHZ-LC. Both parts operate at 25.000 MHz and share identical compliance certifications (ROHS3, REACH Unaffected) and moisture sensitivity ratings (MSL 1). Verification of circuit-level compatibility with the specific output type (HCMOS, TTL) and supply voltage (3.3V) of the substitute is required based on your application schematic.

Q: What are the key differences between the main part and the substitute?

A: The primary differences are product status and packaging specifications. The ASFL-25.000MHZ-LC is obsolete with limited inventory, while the ASFL1-25.000MHZ-L-T is in active production with substantially higher availability. The substitute provides detailed specifications including 3.3V supply voltage, HCMOS/TTL output, ±100ppm frequency stability, and 4-SMD surface mount packaging with dimensions of 5.00mm x 3.20mm.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the ASFL-25.000MHZ-LC and ASFL1-25.000MHZ-L-T maintain identical RoHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity ratings. No additional compliance documentation or design modifications are required when substituting between these parts.

Q: What is the package type of the substitute part?

A: The ASFL1-25.000MHZ-L-T uses a 4-SMD, No Lead surface mount package with dimensions of 5.00mm length x 3.20mm width and a maximum seated height of 1.30mm. This is a standard surface mount oscillator package suitable for automated assembly processes.

Q: How does the frequency stability of the substitute compare to the main part?

A: The ASFL1-25.000MHZ-L-T specifies ±100ppm frequency stability. The ASFL-25.000MHZ-LC does not provide frequency stability specifications in the available documentation. Confirm that ±100ppm stability meets your application requirements before implementation.

Q: What supply voltage does the substitute part require?

A: The ASFL1-25.000MHZ-L-T operates at 3.3V supply voltage with a maximum supply current of 15mA during normal operation and 10µA during disable mode. Verify that your circuit design accommodates 3.3V operation before substitution.
