ASFL1-10.000MHZ-EC-T Equivalent & Substitute Parts

Part Overview

The ASFL1-10.000MHZ-EC-T is a 10 MHz crystal oscillator manufactured by Abracon LLC, designed for applications requiring HCMOS and TTL compatible output signals. This surface mount oscillator operates at 3.3V with enable/disable functionality, housed in a compact 4-SMD, No Lead package measuring 5.00mm x 3.20mm. The part is currently active in production and maintains full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements allow for variations in frequency stability, operating temperature range, or other non-critical electrical parameters while maintaining core functionality, package compatibility, and supply voltage specifications.

The ASFL1-10.000MHZ-EC-T has two qualified substitutes within the ASFL1 series, both manufactured by Abracon LLC and sharing identical physical and electrical core specifications while differing in frequency stability and operating temperature performance.

Parameter Comparison

Engineering Selection Recommendations

ASFL1-10.000MHZ-EK-T (Upgrade Substitute): This variant offers improved frequency stability at ±30ppm compared to the main part's ±50ppm specification, while maintaining identical operating temperature range (-20°C ~ 70°C), supply voltage, and package configuration. Selection of this part is appropriate for applications where tighter frequency tolerance is required without extending the operating temperature envelope. All compliance certifications remain equivalent.

ASFL1-10.000MHZ-L-T (MFR Recommended Substitute): This variant extends the operating temperature range to -40°C ~ 85°C, accommodating industrial and extended-temperature applications. The frequency stability specification is ±100ppm, representing a relaxation from the main part's ±50ppm. This part is suitable for designs requiring wider temperature operation where frequency stability requirements are less stringent. All compliance certifications and package specifications remain identical.

Selection between these substitutes depends solely on application requirements for frequency stability and operating temperature range. All three parts maintain identical supply voltage, output type, package dimensions, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can ASFL1-10.000MHZ-EK-T be used as a direct replacement for ASFL1-10.000MHZ-EC-T?

A: Yes. Both parts share identical frequency (10 MHz), output type (HCMOS, TTL), supply voltage (3.3V), enable/disable function, package configuration (4-SMD, No Lead), and physical dimensions (5.00mm x 3.20mm x 1.30mm max height). The EK-T variant provides superior frequency stability (±30ppm vs. ±50ppm) and operates within the same temperature range (-20°C ~ 70°C).

Q: What is the primary difference between ASFL1-10.000MHZ-L-T and the main part?

A: The L-T variant extends the operating temperature range from -20°C ~ 70°C to -40°C ~ 85°C, enabling use in industrial and extreme temperature environments. Frequency stability is relaxed to ±100ppm. All other electrical and physical specifications remain identical.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 4-SMD, No Lead package with identical footprint dimensions (5.00mm x 3.20mm) and maximum seated height (1.30mm). PCB layout and reflow profiles remain unchanged across all variants.

Q: Do these substitutes maintain the same compliance certifications?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. ECCN and HTSUS classifications are identical.

Q: Which substitute should be selected for a design with strict frequency tolerance requirements?

A: ASFL1-10.000MHZ-EK-T provides the tightest frequency stability at ±30ppm. Selection of this variant is appropriate when application specifications demand superior frequency accuracy within the standard operating temperature range.

Q: Which substitute is recommended for industrial temperature applications?

A: ASFL1-10.000MHZ-L-T is the manufacturer-recommended option for applications requiring extended temperature operation (-40°C ~ 85°C). This part is suitable when frequency stability requirements are less stringent than the main part specification.
