Key Parameters

Substitute Part Grouping Explanation

The SXO75C3C481-20.000M from Suntsu Electronics, Inc. qualifies as a direct substitute based on the following critical parameters:

• Identical frequency: 20 MHz
• Identical output type: CMOS
• Identical supply voltage: 3.3V
• Identical function: Enable/Disable
• Identical frequency stability: ±25ppm
• Identical operating temperature range: -40°C ~ 85°C
• Identical package / case: 4-SMD, No Lead
• Identical physical dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Identical mounting type: Surface Mount
• Identical RoHS compliance: ROHS3 Compliant
• Identical REACH status: REACH Unaffected

All electrical and mechanical parameters align within the allowed substitution criteria for this oscillator category.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and full ROHS3 compliance with REACH unaffected designation. The SXO75C3C481-20.000M demonstrates lower maximum supply current (16mA versus 25mA) and reduced seated height (1.60mm versus 1.90mm), which may provide advantages in power-constrained or space-limited applications. The substitute part is suitable for direct replacement in designs requiring 20 MHz CMOS oscillator functionality with 3.3V supply and enable/disable control.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3C481-20.000M replace the CPPFXC7L-A7BR-20.0TS in existing designs?

A: Yes. Both parts share identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, and package specifications. The substitute part is mechanically and electrically compatible for direct replacement.

Q: What are the differences between these two parts?

A: The primary differences are maximum supply current (16mA for Suntsu versus 25mA for Cardinal) and seated height (1.60mm versus 1.90mm). Both differences favor the substitute part in terms of power efficiency and PCB clearance.

Q: Are both parts suitable for the same PCB layout?

A: Yes. Both parts use identical 4-SMD, No Lead packaging with matching footprint dimensions of 7.00mm x 5.00mm. The reduced height of the substitute part does not create compatibility issues.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. The SXO75C3C481-20.000M offers lower power consumption and reduced height. The CPPFXC7L-A7BR-20.0TS may be selected based on supply chain availability or established vendor relationships.
