Substitute Part Grouping Explanation

Substitution of the 830003110B is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part LFXTAL003110BULK from IQD Frequency Products matches the main part across the following key criteria:

Frequency specification of 4.9152 MHz with identical tolerance of ±20ppm and stability of ±50ppm ensures timing accuracy in target applications. Load capacitance of 30pF and ESR of 100 Ohms must remain constant to maintain circuit performance and oscillation characteristics. The HC-49/U package format and through-hole mounting type provide mechanical and board-level compatibility. Physical dimensions of 11.05mm × 4.65mm with maximum seated height of 13.46mm ensure fit within existing PCB layouts and component spacing. Operating temperature range of -10°C to 60°C defines the thermal operating envelope. Both parts maintain RoHS3 compliance and fundamental mode operation.

Parameter Comparison

Engineering Selection Recommendations

Both the 830003110B and LFXTAL003110BULK are active production parts with full RoHS3 compliance. Selection between these parts is based on availability, supply chain considerations, and inventory status rather than technical performance differences.

Both parts carry identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. The LFXTAL003110BULK carries REACH Affected status, while the 830003110B carries REACH Unaffected status. Both parts are classified under ECCN EAR99 and HTSUS 8541.60.0030. Direct substitution is supported for applications requiring 4.9152 MHz timing with the specified load capacitance and ESR characteristics.

Frequently Asked Questions (FAQ)

Q: Can the LFXTAL003110BULK directly replace the 830003110B in an existing circuit?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The frequency, tolerance, load capacitance, ESR, package format, and mounting type are identical, enabling direct board-level substitution without circuit modification.

Q: Are there differences in operating temperature performance between these parts?

A: No. Both parts operate across the identical temperature range of -10°C to 60°C with the same frequency stability specification of ±50ppm.

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts use the HC-49/U package with identical physical dimensions of 11.05mm length × 4.65mm width and maximum seated height of 13.46mm. PCB layout and component spacing remain unchanged.

Q: What is the significance of the REACH status difference?

A: The 830003110B carries REACH Unaffected status, while the LFXTAL003110BULK carries REACH Affected status. This distinction relates to regulatory substance tracking but does not affect electrical performance or substitution eligibility. Selection should be based on specific regulatory requirements of the end application or region.

Q: Are both parts RoHS compliant?

A: Yes. Both the 830003110B and LFXTAL003110BULK maintain full RoHS3 compliance.

Q: What load capacitance value should be used with either part?

A: Both parts are specified for 30pF load capacitance. The oscillator circuit must be designed to present this load capacitance to the crystal for proper frequency accuracy and startup characteristics.

Q: Is the 100 Ohms ESR specification critical for circuit design?

A: Yes. The 100 Ohms ESR specification is a key parameter that affects oscillator circuit design, particularly in the selection of load capacitors and amplifier gain. Both substitute parts maintain this specification identically.
