Frequently Asked Questions (FAQ)

Q: Why is the ASFL-25.000MHZ classified as obsolete?

A: The ASFL-25.000MHZ has reached end-of-life status with Abracon LLC. The manufacturer has transitioned to the ASFL1 series for 25 MHz oscillator applications. The substitute part ASFL1-25.000MHZ-L-T represents the active product line continuation.

Q: Are the ASFL-25.000MHZ and ASFL1-25.000MHZ-L-T electrically compatible?

A: Both components operate at 25 MHz and share identical compliance certifications (ROHS3, REACH unaffected) and moisture sensitivity levels (MSL 1). The substitute provides HCMOS and TTL output options with 3.3V supply voltage and operates across -40°C to 85°C temperature range.

Q: What is the package difference between these parts?

A: The ASFL1-25.000MHZ-L-T uses a 4-SMD, No Lead surface mount package with dimensions of 5.00mm L x 3.20mm W x 1.30mm height (seated). The original ASFL-25.000MHZ packaging specifications are not detailed in available documentation.

Q: Does the substitute part require different handling or storage procedures?

A: No. Both components share MSL 1 (Unlimited) classification, indicating identical moisture sensitivity levels and storage requirements. No changes to handling procedures are necessary.

Q: Is the ASFL1-25.000MHZ-L-T available in the same packaging format?

A: The ASFL1-25.000MHZ-L-T is supplied in Cut Tape (CT) and Digi-Reel® packaging formats. Current inventory includes 17,736 pieces in stock, ensuring availability for production requirements.

Q: What certifications does the substitute part carry?

A: The ASFL1-25.000MHZ-L-T maintains ROHS3 compliance, REACH unaffected status, and carries ECCN classification EAR99 with HTSUS code 8542.39.0001.
