LFXTAL059596 30 MHz Crystal Equivalent & Substitute Parts

Part Overview

The LFXTAL059596 is a 30 MHz fundamental mode crystal oscillator manufactured by IQD Frequency Products, designed for surface mount applications requiring precise frequency control. This component operates across the industrial temperature range of -40°C to 85°C and is specified with ±15ppm frequency tolerance and 10pF load capacitance. The part is currently in active production status with ROHS3 compliance and is available in high volume inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to supply constraints, design flexibility, or procurement optimization.

Engineering Selection Recommendations

Both the LFXTAL059596 and 830059596 are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on procurement availability and supply chain requirements rather than technical performance differentiation.

The LFXTAL059596 (IQD Frequency Products, IQXC-42 series) is available with 847 pieces in current inventory. The 830059596 (Würth Elektronik, WE-XTAL series) is available with 4008 pieces in current inventory, providing greater stock availability for high-volume applications.

Both components are classified under ECCN EAR99 and HTSUS 8541.60.0060, indicating equivalent regulatory treatment for export and tariff purposes. No technical performance advantage exists between the two parts; selection should be driven by supply chain logistics and cost considerations.

Frequently Asked Questions (FAQ)

Q: Can the 830059596 be used as a direct replacement for the LFXTAL059596 in existing designs?

A: Yes. The 830059596 is a parametric equivalent with identical electrical specifications (30 MHz, ±15 ppm tolerance, 10 pF load capacitance, 80 Ohms ESR), identical mechanical package (4-SMD, No Lead, 2.00 x 1.60 mm), and identical operating temperature range (-40°C to 85°C). No circuit modifications or PCB layout changes are required.

Q: Are there any differences in RoHS or environmental compliance between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under the same ECCN and HTSUS codes. Environmental and regulatory compliance is identical.

Q: What is the significance of the 4-SMD, No Lead package specification?

A: This package designation indicates a surface mount crystal in a 4-pad configuration without external leads. Both parts use this identical package type, ensuring compatibility with the same PCB footprint and reflow soldering process.

Q: Does frequency stability (±20 ppm) differ from frequency tolerance (±15 ppm)?

A: Frequency tolerance (±15 ppm) specifies the initial accuracy at room temperature upon delivery. Frequency stability (±20 ppm) specifies the maximum frequency variation across the full operating temperature range (-40°C to 85°C). Both parameters are identical between the LFXTAL059596 and 830059596.

Q: Can these crystals be used interchangeably in applications requiring precise timing?

A: Yes. Both parts meet the same frequency tolerance and stability specifications. Circuit performance is determined by these electrical parameters, which are identical. The choice between manufacturers does not affect timing accuracy or circuit functionality.
