Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance. Selection between parametric equivalents and similar equivalents depends on circuit load capacitance requirements.

Parametric Equivalents (LFXTAL082129REEL, 830108212909, C1E-32.000-8-1015-X-R, C1E-32.000-8-1015-X-M) are direct replacements with identical 8pF load capacitance specifications and are suitable for applications where the original 8pF load capacitance is a design requirement.

Similar Equivalent (C1E-32.000-10-1015-X-R) features 10pF load capacitance and is suitable only for applications where the circuit design accommodates 10pF load capacitance without performance degradation.

All parts share identical frequency, tolerance, ESR, package form factor, operating temperature range, and physical dimensions. REACH compliance status is consistent across all parts.

Frequently Asked Questions (FAQ)

Q: Can C1E-32.000-10-1015-X-R be used as a direct replacement for LFXTAL082129?

A: C1E-32.000-10-1015-X-R is electrically compatible in terms of frequency, tolerance, and ESR, but differs in load capacitance (10pF versus 8pF). Substitution is valid only if the circuit design accommodates 10pF load capacitance. Verify circuit schematic load capacitance specifications before selection.

Q: What is the difference between LFXTAL082129 and LFXTAL082129REEL?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. LFXTAL082129REEL indicates packaging in tape and reel format with higher inventory availability (4,224 pcs versus 1,100 pcs).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance. Würth Elektronik part 830108212909 does not specify MSL rating but maintains ROHS3 compliance and REACH unaffected status.
