Substitute Part Grouping Explanation

Substitute parts for the LFXTAL059597 are identified through parametric equivalence matching. The substitution criteria are based on the following critical parameters that must remain constant across all equivalent components:

Mandatory Matching Parameters:

• Frequency: 32.0000 MHz (exact match required)
• Frequency Tolerance: ±15 ppm (exact match required)
• Load Capacitance: 10 pF (exact match required)
• ESR: 80 Ohms (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 2.00mm L x 1.60mm W x 0.50mm H max (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Operating Mode: Fundamental (exact match required)
• Regulatory Compliance: ROHS3 Compliant (exact match required)

The Würth Elektronik part 830059597 meets all mandatory matching parameters and is classified as a parametric equivalent suitable for direct substitution in applications utilizing the LFXTAL059597.

Parameter Comparison

Engineering Selection Recommendations

Both the LFXTAL059597 and 830059597 are active production components with full regulatory compliance. Selection between these parts should be based on the following engineering considerations:

Availability and Lead Time: The Würth Elektronik 830059597 maintains higher inventory levels (6755 pcs) compared to the IQD LFXTAL059597 (864 pcs), which may influence procurement timelines for high-volume production requirements.

Regulatory Compliance: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance directives applicable to electronic components in the European Union and equivalent markets.

Packaging and Logistics: Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes. The identical physical dimensions and 4-SMD, No Lead package configuration ensure mechanical compatibility with existing PCB layouts and pick-and-place equipment.

Electrical Performance: Complete parametric equivalence across frequency, tolerance, load capacitance, ESR, and operating temperature range ensures functional interchangeability without circuit redesign or recalibration requirements.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 830059597 be used as a direct replacement for the IQD LFXTAL059597 without PCB modifications?

A: Yes. Both components share identical electrical specifications, physical dimensions, and package configuration. No PCB layout changes or circuit modifications are required for substitution.

Q: Are there any differences in frequency accuracy between these two parts?

A: No. Both components are specified with ±15 ppm frequency tolerance and ±20 ppm frequency stability, ensuring equivalent timing accuracy in applications.

Q: What is the significance of the 10 pF load capacitance specification?

A: The 10 pF load capacitance is the capacitive load for which the crystal frequency is calibrated. Both substitute parts are calibrated to this identical specification, ensuring that oscillator circuits designed for one part will operate at the correct frequency with the other.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the LFXTAL059597 and 830059597 are rated for -40°C to 85°C operation, covering industrial temperature applications.

Q: What does the 80 Ohm ESR specification mean for circuit design?

A: ESR (Equivalent Series Resistance) is the internal resistance of the crystal. The 80 Ohm specification is identical for both parts and must be matched to the oscillator circuit design. Both components are suitable for circuits designed around this ESR value.

Q: Are there any moisture sensitivity concerns with these components?

A: No. Both parts are specified as Not Applicable for Moisture Sensitivity Level (MSL), indicating they do not require special moisture control during storage or handling.

Q: Can these crystals be used interchangeably in real-time clock (RTC) applications?

A: Yes. The 32 MHz frequency with ±15 ppm tolerance is standard for RTC and microcontroller timing applications. Both components are suitable for such applications without modification.

Q: What is the difference between frequency tolerance and frequency stability?

A: Frequency tolerance (±15 ppm) specifies the initial accuracy at calibration. Frequency stability (±20 ppm) accounts for frequency variation over the operating temperature range. Both specifications are identical for both parts.
