Substitute Part Grouping Explanation

Substitution of the LFXTAL059585 is determined by strict equivalence across the following critical parameters: frequency (20 MHz), frequency tolerance (±15ppm), load capacitance (10pF), ESR (120 Ohms), operating mode (Fundamental), package type (4-SMD, No Lead), physical dimensions (2.00mm x 1.60mm), and operating temperature range (-40°C to 85°C). All substitute parts must maintain identical electrical performance characteristics and mechanical compatibility to ensure direct replacement without circuit redesign or board layout modification. Regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification) is maintained across all identified equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both the LFXTAL059585 and 830059585 are active production components with identical electrical and mechanical specifications. Selection between these parts may be based on supply chain availability, lead time, or procurement preferences. The LFXTAL059585 (IQD Frequency Products) currently maintains 773 pieces in stock, while the 830059585 (Würth Elektronik) maintains 3265 pieces in stock. Both components satisfy ROHS3 compliance requirements and are classified as REACH Unaffected. Direct substitution is supported without circuit modification or performance degradation when electrical parameters, package dimensions, and operating conditions remain within specified limits.

Frequently Asked Questions (FAQ)

Q: Can the 830059585 directly replace the LFXTAL059585 in existing designs?

A: Yes. Both parts are parametrically equivalent across all critical specifications: 20 MHz frequency, ±15ppm tolerance, 10pF load capacitance, 120 Ohms ESR, 4-SMD package, and -40°C to 85°C operating range. No circuit redesign or board layout modification is required.

Q: Are there differences in package dimensions between these parts?

A: No. Both the LFXTAL059585 and 830059585 share identical package dimensions of 2.00mm x 1.60mm with a maximum seated height of 0.50mm, ensuring mechanical compatibility in surface mount applications.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99, meeting identical regulatory requirements for industrial and commercial applications.

Q: What is the significance of the ±15ppm frequency tolerance specification?

A: The ±15ppm frequency tolerance defines the maximum allowable deviation from the nominal 20 MHz frequency across the operating temperature range and component lifetime. This specification determines suitability for timing-critical applications and must be matched in substitute parts.

Q: Are there any differences in ESR (Equivalent Series Resistance) between the two parts?

A: No. Both the LFXTAL059585 and 830059585 specify 120 Ohms ESR, which directly affects circuit oscillation characteristics and must remain constant for equivalent performance.

Q: What load capacitance value should be used with these crystals?

A: Both parts are specified for 10pF load capacitance. The oscillator circuit design must match this load capacitance value to achieve the specified frequency tolerance and stability performance.
