Substitute Part Grouping Explanation

Substitution of the 830002995B is determined by strict equivalence across the following critical parameters:

Frequency matching at 32.768 kHz with identical frequency tolerance of ±20ppm ensures timing accuracy in RTC and clock applications. Load capacitance of 12.5pF and ESR of 50 kOhms must be maintained to preserve circuit oscillation characteristics and startup behavior. Operating temperature range of -40°C ~ 85°C defines the thermal envelope for industrial and consumer applications. Through-hole mounting with cylindrical can, radial package configuration ensures mechanical fit and PCB compatibility. Fundamental operating mode confirms the crystal operates at its base frequency without harmonic multiplication.

The substitute part LFXTAL002995BULK from IQD Frequency Products meets all these electrical and mechanical criteria, providing functional equivalence for direct replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

The LFXTAL002995BULK (IQD Frequency Products) carries REACH Unaffected status. Both components are ROHS3 Compliant and classified under ECCN EAR99 for export control purposes.

Current inventory levels show 1,817 pieces available for the 830002995B and 10,152 pieces for the LFXTAL002995BULK. Component selection should account for project timelines, regulatory requirements specific to end-use applications, and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can the LFXTAL002995BULK directly replace the 830002995B in existing circuit designs?

A: Yes. Both components share identical electrical specifications (32.768 kHz, ±20ppm tolerance, 12.5pF load capacitance, 50 kOhms ESR) and mechanical packaging (cylindrical can, radial through-hole, 3.00mm x 8.20mm dimensions). Direct substitution is supported without circuit modification.

Q: What is the significance of the frequency tolerance ±20ppm?

A: Frequency tolerance of ±20ppm defines the maximum deviation from the nominal 32.768 kHz frequency across the operating temperature range and component lifetime. This specification is critical for real-time clock accuracy and timing applications. Both parts maintain identical tolerance, ensuring equivalent performance.

Q: Are there differences in regulatory compliance between these parts?

A: Both components are ROHS3 Compliant and classified as EAR99 for export control. The primary difference is REACH status: the 830002995B is REACH Affected, while the LFXTAL002995BULK is REACH Unaffected. Applications subject to REACH regulations may require specific part selection based on end-use location and regulatory jurisdiction.

Q: Does load capacitance affect circuit design?

A: Load capacitance of 12.5pF is a design parameter that must match the oscillator circuit's capacitive load specification. Both substitute parts maintain this specification, ensuring compatibility with circuits designed for 12.5pF load capacitance. Mismatched load capacitance would result in frequency deviation outside tolerance limits.

Q: What does ESR of 50 kOhms indicate?

A: Equivalent Series Resistance (ESR) of 50 kOhms represents the internal resistance of the crystal element. This specification affects oscillator startup behavior and power consumption. Both parts maintain identical ESR, ensuring equivalent circuit performance and startup characteristics.

Q: Are these components suitable for industrial temperature applications?

A: Yes. Both components operate across the temperature range of -40°C ~ 85°C, which covers industrial and extended commercial temperature requirements. Frequency tolerance of ±20ppm is maintained throughout this operating range.

Q: What is the difference between Fundamental and Harmonic operating modes?

A: Fundamental mode indicates the crystal oscillates at its base frequency (32.768 kHz) without harmonic multiplication. Both substitute parts operate in Fundamental mode, confirming direct frequency equivalence without frequency multiplication circuits.
