Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASD-12.000MHZ-LC-T is determined by strict equivalence across the following critical parameters:

• Frequency: 12 MHz (exact match required)
• Output Type: HCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm) (exact match required)
• Height - Seated (Max): 0.039" (1.00mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

The LFSPXO056289 from IQD Frequency Products meets all critical electrical and mechanical parameters, qualifying it as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ASD-12.000MHZ-LC-T and LFSPXO056289 are active production parts with ROHS3 compliance. The primary distinction is maximum supply current: the ASD-12.000MHZ-LC-T draws 5mA maximum, while the LFSPXO056289 draws 10mA maximum. Selection between these parts should be based on power budget constraints within the target application. Both parts meet identical electrical and mechanical specifications for frequency, output type, stability, temperature range, and package form factor, ensuring functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can LFSPXO056289 replace ASD-12.000MHZ-LC-T in existing designs?

A: Yes. Both parts meet identical specifications for frequency (12 MHz), output type (HCMOS), supply voltage (3.3V), enable/disable function, frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), and package dimensions (4-SMD, No Lead, 2.50mm x 2.00mm x 1.00mm max height). The LFSPXO056289 has a higher maximum supply current (10mA vs 5mA), which must be evaluated against circuit power requirements.

Q: Are there packaging differences between these parts?

A: No. Both parts use identical 4-SMD, No Lead surface mount packaging with matching physical dimensions of 0.098" L x 0.079" W (2.50mm x 2.00mm) and maximum seated height of 0.039" (1.00mm). PCB layout and reflow profiles remain unchanged.

Q: What compliance certifications apply to both parts?

A: Both the ASD-12.000MHZ-LC-T and LFSPXO056289 are ROHS3 compliant. The LFSPXO056289 is REACH Affected, while the ASD-12.000MHZ-LC-T is REACH Unaffected. Regulatory requirements for the target application determine which certification status is applicable.

Q: What is the primary substitution criterion?

A: Substitution is based on exact equivalence across electrical parameters (frequency, output type, supply voltage, function, stability, temperature range) and mechanical parameters (package type, dimensions, height). Current consumption differences do not prevent substitution but require power budget verification.
