Parameter Comparison

Engineering Selection Recommendations

Both the ASD-12.000MHZ-LCS-T and LFSPXO056289 are active production parts with ROHS3 compliance and identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Abracon ASD-12.000MHZ-LCS-T:

• Preferred when Cut Tape or Digi-Reel® packaging is required
• Lower maximum supply current specification (5mA vs 10mA)
• Current inventory: 1838 units

IQD LFSPXO056289:

• Preferred when Tape & Reel (TR) packaging is required for high-volume production
• Higher maximum supply current specification (10mA)
• Current inventory: 2842 units
• REACH Affected status (vs. REACH Unaffected for Abracon part)

Both parts share identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, and physical dimensions. The substitute part is electrically and mechanically compatible for direct PCB footprint replacement.

Frequently Asked Questions (FAQ)

Q: Can the LFSPXO056289 be used as a direct replacement for the ASD-12.000MHZ-LCS-T?

A: Yes. Both parts share identical electrical specifications (12 MHz, HCMOS output, 3.3V supply, ±50ppm stability, -40°C to 85°C operating range) and mechanical specifications (4-SMD No Lead package, 2.50mm x 2.00mm footprint, 1.00mm maximum height). The parts are pin-compatible and footprint-compatible for direct substitution on PCBs.

Q: What is the difference in packaging between these two parts?

A: The ASD-12.000MHZ-LCS-T is supplied in Cut Tape (CT) and Digi-Reel® formats, while the LFSPXO056289 is supplied in Tape & Reel (TR) format. Both formats are standard surface mount packaging; selection depends on assembly process requirements and volume needs.

Q: Are there differences in power consumption between these parts?

A: The maximum supply current differs: ASD-12.000MHZ-LCS-T specifies 5mA maximum, while LFSPXO056289 specifies 10mA maximum. Both values are within typical operating ranges for 12 MHz HCMOS oscillators. The disable mode current for the IQD part is not specified in available data.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and share the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The Abracon part has REACH Unaffected status, while the IQD part has REACH Affected status. Compliance requirements should be verified against specific application and regional regulations.

Q: What is the frequency stability specification for both parts?

A: Both parts specify ±50ppm frequency stability across the -40°C to 85°C operating temperature range. This specification is identical for both the ASD-12.000MHZ-LCS-T and LFSPXO056289.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that the packaging format (Cut Tape vs. Tape & Reel) is compatible with your assembly process. The electrical and mechanical specifications are identical, allowing for direct substitution without circuit design modifications or PCB layout changes.
