The 830003056B (Würth Elektronik) is RoHS3 compliant with REACH Unaffected status, providing regulatory clarity for applications with strict material composition requirements.

The LFXTAL003056BULK (IQD Frequency Products) is RoHS3 compliant with REACH Affected status, indicating potential substance of concern declarations under REACH regulations. This part is suitable for applications where REACH-affected components are acceptable.

Both parts are classified under ECCN EAR99 and HTSUS 8541.60.0030, indicating identical export control and tariff classifications. Selection should be based on supply availability, cost considerations, and specific regulatory requirements of the end application or geographic market.

Frequently Asked Questions (FAQ)

Q: Can LFXTAL003056BULK replace 830003056B in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The LFXTAL003056BULK operates at the same 3.579545 MHz frequency with identical tolerance (±20ppm), stability (±50ppm), load capacitance (20pF), and ESR (150 Ohms). Both use HC-49/U through-hole packaging with identical physical dimensions and height specifications. Direct substitution is supported without circuit modification.

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

A: Both parts are RoHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.60.0030) classifications. The primary difference is REACH status: the 830003056B is REACH Unaffected, while the LFXTAL003056BULK is REACH Affected. Applications subject to REACH regulations should confirm acceptability of REACH-affected components before selecting the IQD part.

Q: Do these crystals require different circuit design considerations?

A: No. Both crystals operate in fundamental mode with identical electrical specifications. Circuit design parameters including load capacitance (20pF), ESR (150 Ohms), frequency tolerance (±20ppm), and operating temperature range (-10°C to 60°C) are identical. Existing circuit designs require no modification for substitution.

Q: Are the physical dimensions identical for PCB layout purposes?

A: Yes. Both parts share identical HC-49/U package specifications: 0.435" length x 0.183" width (11.05mm x 4.65mm) with maximum seated height of 0.530" (13.46mm). PCB footprints and through-hole spacing are identical, requiring no layout changes for substitution.

Q: What is the operating temperature range for both parts?

A: Both the 830003056B and LFXTAL003056BULK operate across the identical temperature range of -10°C to 60°C. Frequency stability of ±50ppm is maintained throughout this range.
