Substitute Part Grouping Explanation

Substitution eligibility for the CSX-750FBB12000000T is determined by strict equivalence across the following parameters:

• Frequency: 12 MHz (exact match required)
• Output: CMOS (electrical interface compatibility)
• Supply Voltage: 3.3V (power supply compatibility)
• Function: Enable/Disable (functional feature match)
• Frequency Stability: ±50ppm (timing accuracy specification)
• Operating Temperature: -20°C ~ 70°C (thermal operating range)
• Package: 4-SMD, No Lead (mechanical and electrical footprint compatibility)
• Dimensions: 7.00mm x 5.00mm (board layout compatibility)
• Height: 1.60mm maximum (clearance and assembly compatibility)
• RoHS Compliance: ROHS3 (regulatory requirement)

The SXO75C3A271-12.000M from Suntsu Electronics, Inc. meets all substitution criteria across these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the CSX-750FBB12000000T and SXO75C3A271-12.000M are Active status products with ROHS3 compliance and EAR99 export classification. The parts are electrically and mechanically equivalent across all critical substitution parameters. Maximum supply current differs by 1mA (15mA vs 16mA), which remains within acceptable tolerance for 3.3V CMOS oscillator applications. Both parts maintain identical frequency stability, operating temperature range, and physical footprint specifications required for direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3A271-12.000M directly replace the CSX-750FBB12000000T on a PCB?

A: Yes. Both parts share identical package type (4-SMD, No Lead), dimensions (7.00mm x 5.00mm), and maximum height (1.60mm). The electrical interface is equivalent: 12 MHz CMOS output, 3.3V supply, and enable/disable functionality. No PCB layout modifications are required.

Q: Are there differences in power consumption between these parts?

A: Maximum supply current is 15mA for the CSX-750FBB12000000T and 16mA for the SXO75C3A271-12.000M. This 1mA difference is negligible for 3.3V CMOS oscillator applications and does not affect system-level power budget calculations.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and classified as EAR99 for export purposes. Both carry the same HTSUS code (8542.39.0001).

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

A: Both parts maintain ±50ppm frequency stability across the operating temperature range of -20°C to 70°C.

Q: Are there packaging differences between these parts?

A: The CSX-750FBB12000000T is supplied in Tape & Reel (TR) packaging, while the SXO75C3A271-12.000M is supplied in Bulk packaging. The component itself is identical; packaging format differs only for inventory and handling purposes.
