Substitute Part Grouping Explanation

Substitution of the 830003099B is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following specifications without deviation:

• Frequency: 4.433619 MHz (exact match required)
• Frequency Tolerance: ±20ppm
• Frequency Stability: ±30ppm
• Load Capacitance: 20pF
• ESR: 100 Ohms
• Operating Mode: Fundamental
• Operating Temperature Range: -10°C to 60°C
• Package / Case: HC-49/U
• Mounting Type: Through Hole
• Physical Dimensions: 0.435" L x 0.183" W (11.05mm x 4.65mm)
• Height - Seated (Max): 0.530" (13.46mm)

The identified substitute part meets all these parameters and maintains active product status, ensuring functional and mechanical compatibility in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the primary part (830003099B) and the substitute part (LFXTAL003099BULK) are active products with RoHS3 compliance status. The selection between these components is based on availability, supply chain requirements, and inventory levels rather than technical performance differences.

The Würth Elektronik 830003099B maintains REACH Unaffected status, while the IQD Frequency Products LFXTAL003099BULK carries REACH Affected designation. Both components are classified under ECCN EAR99 and HTSUS 8541.60.0030.

Direct substitution is permissible in applications where the 830003099B is specified, provided that regulatory compliance requirements for the end application are satisfied. The identical electrical characteristics, mechanical dimensions, and operating parameters ensure functional equivalence in circuit operation.

Frequently Asked Questions (FAQ)

Q: Can LFXTAL003099BULK be used as a direct replacement for 830003099B?
