Parameter Comparison

Engineering Selection Recommendations

Both the LFXTAL072546 and 830072546 are active production components with full RoHS3 compliance and REACH unaffected status. The Würth Elektronik 830072546 substitute provides parametric equivalence across all electrical and mechanical specifications, enabling direct replacement in circuit designs. Selection between these components is based on availability, supply chain requirements, and procurement preferences, as both components satisfy identical functional and compliance requirements for 48 MHz crystal oscillator applications in the 4-SMD, No Lead package format.

Frequently Asked Questions (FAQ)

Q: Can the 830072546 be used as a direct replacement for the LFXTAL072546?

A: Yes. The 830072546 is a parametric equivalent with identical frequency, tolerance, stability, load capacitance, ESR, operating temperature range, and physical dimensions. Both components are housed in the same 4-SMD, No Lead package and maintain equivalent RoHS3 compliance.

Q: Are there any differences in the physical package between these two parts?

A: No. Both components share identical dimensions of 0.079" L x 0.063" W (2.00mm x 1.60mm) with a maximum seated height of 0.020" (0.50mm). The 4-SMD, No Lead package format is identical, ensuring compatibility with existing PCB layouts and assembly processes.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in frequency (48 MHz), frequency tolerance (±15ppm), frequency stability (±20ppm), load capacitance (10pF), ESR (60 Ohms), operating mode (Fundamental), operating temperature range (-40°C to 85°C), and package format (4-SMD, No Lead). All parameters must match exactly for direct interchangeability.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LFXTAL072546 and 830072546 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8541.60.0060).

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

A: Frequency tolerance (±15ppm) specifies the initial accuracy of the crystal at the time of manufacture. Frequency stability (±20ppm) defines the maximum frequency variation over the operating temperature range of -40°C to 85°C. Both parameters are identical for these substitute parts.
