Key Parameters

Substitute Part Grouping Explanation

Substitution of oscillator components is determined by the following critical parameters:

Frequency Compatibility: The substitute part must operate at the same or functionally equivalent frequency to maintain circuit timing specifications.

Output Type: The substitute must provide compatible output signaling (HCMOS, TTL, or equivalent logic families).

Supply Voltage: The substitute must operate within the same or compatible supply voltage range.

Frequency Stability: The substitute must meet or exceed the frequency stability requirements of the original design.

Operating Temperature Range: The substitute must function across the same or broader temperature operating window.

Mounting Type: The substitute must use compatible surface mount or through-hole packaging.

Compliance Standards: The substitute must maintain RoHS and REACH compliance status equivalent to the original part.

The identified substitute part ASFL1-11.0592MHZ-L-T shares the same manufacturer (Abracon LLC), operates in the same frequency band, maintains identical RoHS3 and REACH compliance, and provides compatible oscillator functionality with enhanced availability through active production status.

Engineering Selection Recommendations

Primary Substitute: ASFL1-11.0592MHZ-L-T

The ASFL1-11.0592MHZ-L-T is the recommended substitute for the obsolete ASFL-11.059MHZ-LJS. Both parts are manufactured by Abracon LLC and maintain identical RoHS3 and REACH compliance certifications. The substitute operates at 11.0592 MHz, which is functionally equivalent to the original 11.059 MHz specification within standard oscillator tolerance bands. The substitute part is in active production status with substantial inventory availability (1844 Pcs), ensuring reliable supply chain access.

The substitute provides documented electrical specifications including HCMOS/TTL output compatibility, 3.3V supply voltage operation, ±100ppm frequency stability, and -40°C to 85°C operating temperature range. The 4-SMD surface mount package with no lead configuration is standard for modern oscillator designs and maintains compatibility with contemporary PCB assembly processes.

Both parts share MSL 1 (Unlimited) moisture sensitivity classification, eliminating special handling requirements during storage and assembly.

Frequently Asked Questions (FAQ)

Q: What is the frequency difference between the original ASFL-11.059MHZ-LJS and the substitute ASFL1-11.0592MHZ-L-T?

A: The original part operates at 11.059 MHz while the substitute operates at 11.0592 MHz. This represents a difference of 0.0002 MHz (0.2 kHz), which falls within standard oscillator tolerance specifications and is functionally equivalent for most timing applications.

Q: Why is the original part classified as obsolete?

A: The ASFL-11.059MHZ-LJS has been discontinued by Abracon LLC and is no longer manufactured. The ASFL1 series represents the current production line for equivalent oscillator functionality.

Q: Are the RoHS and REACH compliance statuses identical between the original and substitute parts?

A: Yes. Both the ASFL-11.059MHZ-LJS and ASFL1-11.0592MHZ-L-T are ROHS3 Compliant and REACH Unaffected, maintaining equivalent environmental compliance standards.

Q: What is the moisture sensitivity level for both parts?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures are sufficient without requiring dry-pack storage or baking procedures.

Q: Is the substitute part available in the same packaging format?

A: The substitute ASFL1-11.0592MHZ-L-T is supplied in Tape & Reel (TR) packaging, which is standard for surface mount oscillators. The original part packaging format is not specified in available documentation.

Q: What are the supply voltage requirements for the substitute part?

A: The ASFL1-11.0592MHZ-L-T operates at 3.3V supply voltage with a maximum supply current of 15mA under normal operation and 10µA during disable mode.

Q: Can the substitute part be used as a direct replacement in existing designs?

A: The substitute part is functionally equivalent for oscillator applications requiring 11.059 MHz operation. PCB layout compatibility should be verified based on the 4-SMD, No Lead package dimensions (5.00mm x 3.20mm) and maximum seated height of 1.30mm.
