Substitute Part Grouping Explanation

Substitution eligibility for the 7CA5672001 is determined by strict equivalence across the following critical parameters:

Frequency Specification: The substitute part must operate at exactly 156.25 MHz to maintain system timing requirements and signal integrity.

Output Configuration: CMOS output type is mandatory for voltage level compatibility with receiving circuits.

Supply Voltage: 3.3V supply voltage requirement must be matched to ensure proper oscillator operation and prevent circuit damage.

Enable/Disable Function: The substitute must provide identical enable/disable control functionality for power management applications.

Frequency Stability: ±50ppm stability tolerance must be maintained to meet system timing accuracy specifications.

Operating Temperature Range: The -40°C ~ 85°C operating range must be supported by the substitute part.

Package and Mechanical Compatibility: The 4-SMD, No Lead package with 5.00mm x 3.20mm dimensions and 1.40mm maximum height must be preserved for PCB layout compatibility.

Compliance Standards: RoHS compliance and MSL 1 rating must be maintained.

The substitute part 7C-156.250MBE-T meets all these criteria and is therefore a valid parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 7C-156.250MBE-T is a direct parametric equivalent to the obsolete 7CA5672001. Both parts are manufactured by TXC CORPORATION within the same 7C series and share identical electrical and mechanical specifications across all critical parameters.

Product Status Advantage: The 7C-156.250MBE-T carries an Active product status, ensuring ongoing availability and manufacturing support. This addresses the supply chain risk associated with the Obsolete 7CA5672001.

Compliance Alignment: Both parts maintain RoHS compliance and MSL 1 rating, satisfying regulatory and environmental requirements without modification to existing designs.

Packaging Consideration: The 7C-156.250MBE-T is supplied in Tape & Reel (TR) format, which differs from the standard packaging of the main part. This packaging format is standard for high-volume production environments and does not affect electrical or mechanical compatibility.

Current Specification: The 7C-156.250MBE-T provides a specified maximum supply current of 30mA, offering additional design documentation compared to the main part.

For applications requiring the 156.25 MHz CMOS oscillator with 3.3V supply and enable/disable functionality in a 4-SMD, No Lead package, the 7C-156.250MBE-T provides full electrical and mechanical compatibility with the obsolete 7CA5672001.
