Frequently Asked Questions (FAQ)

Q: Can the ASFL1-100.000MHZ-EC-T be used as a direct replacement for the ASFL-100.000MHZ-EC-T?

A: Yes. The ASFL1-100.000MHZ-EC-T is the direct substitute for the obsolete ASFL-100.000MHZ-EC-T. Both parts share identical frequency, output type, supply voltage, function, package configuration, and compliance certifications.

Q: What is the primary difference between these two parts?

A: The primary difference is the series designation change from ASFL to ASFL1, reflecting the manufacturer's product line evolution. The ASFL-100.000MHZ-EC-T is obsolete, while the ASFL1-100.000MHZ-EC-T is in active production.

Q: Are the physical dimensions identical?

A: Both parts use the same 4-SMD, No Lead surface mount package. The ASFL1-100.000MHZ-EC-T specifies dimensions of 0.197" L x 0.126" W (5.00mm x 3.20mm) with a maximum seated height of 0.051" (1.30mm). These dimensions are consistent with the package type used by both parts.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the ASFL-100.000MHZ-EC-T and ASFL1-100.000MHZ-EC-T are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: What is the packaging format for the substitute part?

A: The ASFL1-100.000MHZ-EC-T is supplied in Tape & Reel (TR) packaging, which is standard for surface mount components in production environments.

Q: Are there any functional differences in enable/disable operation?

A: No. Both parts feature identical enable/disable functionality. The ASFL1-100.000MHZ-EC-T specifies a maximum disable current of 10µA, providing low-power standby operation.

Q: What is the frequency stability specification?

A: The ASFL1-100.000MHZ-EC-T specifies frequency stability of ±50ppm across its operating temperature range of -20°C to 70°C.
