Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TA-49.152MBE-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 49.152 MHz
• Output Configuration: CMOS
• Supply Voltage: 3.3V
• Enable/Disable Function: Required
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Maximum Supply Current: 25mA
• Package Type: 4-SMD, No Lead
• Physical Footprint: 7.00mm x 5.00mm

The two substitute parts identified—CPPC7L-A7BP-49.152TS and CPPLC7L-A7BP-49.152TS—both satisfy all mandatory matching parameters. The primary difference between the main part and substitutes is the resonator technology: the TA-49.152MBE-T uses MEMS technology, while the Cardinal Components substitutes employ crystal-based resonators. Both technologies deliver identical electrical performance within the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Both CPPC7L-A7BP-49.152TS and CPPLC7L-A7BP-49.152TS are functionally equivalent substitutes for the obsolete TA-49.152MBE-T. Selection between these two Cardinal Components options should be based on the following factors:

Product Status: Both substitute parts are classified as Active, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the main part.

Compliance Certifications: Both substitutes carry ROHS3 Compliance and REACH Unaffected designations, meeting current environmental and regulatory requirements. The main part does not specify these certifications.

Physical Clearance: The substitute parts have a maximum seated height of 1.90mm compared to 1.00mm for the main part. PCB layout and component clearance must be verified to ensure the increased height does not create mechanical conflicts in the assembly.

Disable Mode Performance: Both substitutes specify a maximum disable mode current of 50µA, providing defined low-power operation. The main part does not specify this parameter.

Packaging: Both substitutes are supplied in Tape & Reel format, standard for automated assembly operations.

Frequently Asked Questions (FAQ)

Q: Can CPPC7L-A7BP-49.152TS and CPPLC7L-A7BP-49.152TS be used interchangeably with TA-49.152MBE-T?

A: Yes. Both Cardinal Components parts meet all electrical and functional specifications of the TA-49.152MBE-T, including frequency, output type, supply voltage, enable/disable function, frequency stability, operating temperature range, and maximum supply current. The primary difference is resonator technology (crystal versus MEMS) and maximum seated height (1.90mm versus 1.00mm).

Q: What is the significance of the height difference between the main part and substitutes?

A: The TA-49.152MBE-T has a maximum seated height of 1.00mm, while both substitutes measure 1.90mm. This 0.90mm difference must be evaluated against PCB layout constraints, component stacking requirements, and enclosure clearances. If the original design has minimal vertical clearance, the taller substitute may require mechanical redesign.

Q: Are there differences in frequency stability between the main part and substitutes?

A: No. All three parts specify identical frequency stability of ±50ppm across the operating temperature range of -40°C to 85°C.

Q: What is the difference between CPPC7L-A7BP-49.152TS and CPPLC7L-A7BP-49.152TS?

A: Both parts are functionally identical in electrical performance and physical footprint. The designation difference (CPP versus CPPL series within the FIPO™ product line) reflects internal Cardinal Components product categorization. Electrical and mechanical parameters are equivalent.

Q: Does the resonator technology difference (MEMS versus crystal) affect circuit performance?

A: No. Within the specified electrical parameters, both MEMS and crystal-based oscillators deliver identical performance. The choice between technologies is transparent to the circuit design when all electrical specifications are met.

Q: Are the substitute parts available in the same packaging as the original?

A: The substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly. The original part packaging format is not specified in the available data. Verify that Tape & Reel format is compatible with your assembly process.

Q: What compliance advantages do the substitute parts offer?

A: Both CPPC7L-A7BP-49.152TS and CPPLC7L-A7BP-49.152TS carry ROHS3 Compliance and REACH Unaffected certifications. These designations confirm compliance with current environmental regulations. The original part does not specify these certifications.

Q: Is there a supply advantage to using the substitute parts?

A: Yes. Both substitute parts are classified as Active products with current manufacturing status, ensuring ongoing availability. The TA-49.152MBE-T is Obsolete, which may result in limited stock and eventual unavailability.
