Key Parameters

Substitute Part Grouping Explanation

The LFSPXO018045 from IQD Frequency Products qualifies as a direct substitute for the C3392-8.000 based on the following critical parameters:

• Identical frequency: 8 MHz
• Identical output type: HCMOS
• Identical supply voltage: 3.3V
• Identical function: Enable/Disable capability
• Identical package: 4-SMD, No Lead
• Identical frequency stability: ±50ppm
• Identical operating temperature range: 0°C ~ 70°C
• Identical mounting type: Surface Mount
• Identical RoHS compliance: ROHS3 Compliant

Both parts are classified as XO (Standard) oscillators with crystal base resonators and are suitable for direct PCB-level substitution without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Both the C3392-8.000 and LFSPXO018045 are active production parts with full RoHS3 and REACH compliance. The LFSPXO018045 offers a secondary advantage in reduced maximum supply current (7mA versus 18mA) and lower seated height (1.40mm versus 1.80mm), which may benefit power-constrained or space-limited applications. Selection between these parts should be based on availability, lead time, and specific application constraints. Both parts are suitable for direct substitution in 8 MHz HCMOS oscillator applications requiring 3.3V enable/disable functionality.

Frequently Asked Questions (FAQ)

Q: Can the LFSPXO018045 replace the C3392-8.000 in existing designs?

A: Yes. Both parts share identical electrical specifications (8 MHz, HCMOS output, 3.3V supply, enable/disable function, ±50ppm stability) and mechanical compatibility (4-SMD, No Lead package, identical footprint dimensions). No circuit modifications are required.

Q: What are the differences between these two parts?

A: The primary differences are maximum supply current (C3392-8.000: 18mA; LFSPXO018045: 7mA) and seated height (C3392-8.000: 1.80mm; LFSPXO018045: 1.40mm). Both differences favor the LFSPXO018045 for power efficiency and compact PCB designs.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the C3392-8.000 and LFSPXO018045 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the frequency stability specification for these oscillators?

A: Both parts maintain ±50ppm frequency stability across the 0°C to 70°C operating temperature range.

Q: Are the package dimensions identical?

A: Yes. Both parts use a 4-SMD, No Lead package with identical footprint dimensions of 0.283" L x 0.205" W (7.20mm x 5.20mm). The LFSPXO018045 has a lower maximum seated height of 1.40mm compared to 1.80mm for the C3392-8.000.
