Key Parameters

Substitute Part Grouping Explanation

Substitution of the XM-1-012.0M is permissible when the following criteria are met:

Frequency equivalence at 12 MHz with matching frequency stability of ±50ppm ensures circuit timing requirements are preserved. Surface mount packaging in 4-SMD, No Lead configuration maintains PCB layout compatibility. Operating temperature range of -10°C to 60°C must be supported by the substitute part. Fundamental operating mode is required for direct functional replacement.

Load capacitance and ESR values may vary within acceptable design tolerances when the circuit design accommodates component parameter ranges. RoHS3 compliance and REACH Unaffected status ensure regulatory alignment with current environmental standards.

Parameter Comparison

Engineering Selection Recommendations

Both the XM-1-012.0M and LFXTAL032878 maintain Active product status with full RoHS3 compliance and REACH Unaffected designation, ensuring regulatory compliance for current and future applications.

The XM-1-012.0M features a lower ESR of 50 Ohms compared to the LFXTAL032878 at 90 Ohms. The load capacitance difference of 16pF versus 18pF requires circuit design verification to confirm compatibility with oscillator tank circuit parameters.

The LFXTAL032878 offers a smaller physical footprint (5.00mm x 3.20mm versus 7.50mm x 5.00mm) and lower seated height (1.00mm versus 1.30mm), providing advantages for space-constrained PCB layouts.

Selection between these parts should be based on circuit design requirements for load capacitance and ESR tolerance, as well as physical space availability on the target PCB.

Frequently Asked Questions (FAQ)

Q: Can the LFXTAL032878 directly replace the XM-1-012.0M without circuit modification?

A: Direct replacement requires verification that the circuit design accommodates the LFXTAL032878 load capacitance of 18pF and ESR of 90 Ohms. The oscillator tank circuit must be evaluated to confirm these parameter variations remain within acceptable operating margins.

Q: Are there physical mounting differences between these parts?

A: Both parts use 4-SMD, No Lead surface mount packaging. The LFXTAL032878 has a smaller footprint and lower profile, which may require PCB layout adjustment if the original design was optimized for the XM-1-012.0M dimensions.

Q: Do both parts meet the same environmental and regulatory standards?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, with identical operating temperature ranges of -10°C to 60°C and Moisture Sensitivity Level 1 (or equivalent).

Q: What is the primary difference in electrical characteristics?

A: The XM-1-012.0M has lower ESR (50 Ohms) and lower load capacitance (16pF), while the LFXTAL032878 has higher ESR (90 Ohms) and higher load capacitance (18pF). Both maintain identical frequency and stability specifications of 12 MHz at ±50ppm.
