Key Parameters

Substitute Part Grouping Explanation

Substitution of the TA-8.000MBE-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 8 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Package Dimensions: 7.00mm x 5.00mm
• Maximum Supply Current: 25mA

The CPPC7L-A7BP-8.0TS from Cardinal Components Inc. satisfies all mandatory matching parameters. While the base resonator differs (Crystal vs. MEMS), both technologies deliver equivalent electrical performance within the specified parameters. The substitute part maintains identical frequency, output characteristics, voltage supply, enable/disable function, frequency stability, temperature range, and package footprint.

Engineering Selection Recommendations

The CPPC7L-A7BP-8.0TS is a direct functional substitute for the obsolete TA-8.000MBE-T. Selection of this substitute is supported by the following factors:

Product Status: The substitute part maintains Active product status, ensuring long-term availability and manufacturing support compared to the Obsolete main part.

Electrical Equivalence: All critical electrical parameters match exactly: 8 MHz frequency, CMOS output, 3.3V supply, Enable/Disable function, ±50ppm frequency stability, 25mA maximum supply current, and -40°C to 85°C operating temperature range.

Package Compatibility: Both parts use identical 4-SMD, No Lead packaging with 7.00mm x 5.00mm footprint, enabling direct PCB layout compatibility.

Compliance: The substitute part carries ROHS3 and REACH compliance certifications, meeting modern regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Physical Consideration: The substitute part has a maximum seated height of 1.90mm compared to 1.00mm for the main part. PCB clearance verification is required for applications with height constraints.

Resonator Technology: While the main part uses MEMS resonator technology and the substitute uses Crystal resonator technology, both deliver equivalent performance within the specified electrical parameters and frequency stability.

Frequently Asked Questions (FAQ)

Q: Can the CPPC7L-A7BP-8.0TS be used as a direct replacement for the TA-8.000MBE-T?

A: Yes. The substitute part meets all mandatory electrical and mechanical parameters: identical 8 MHz frequency, CMOS output, 3.3V supply voltage, Enable/Disable function, ±50ppm frequency stability, operating temperature range of -40°C to 85°C, 25mA maximum supply current, and 4-SMD, No Lead package with 7.00mm x 5.00mm footprint. PCB layout compatibility is maintained.

Q: What is the difference between MEMS and Crystal resonator technology in these parts?

A: The TA-8.000MBE-T uses MEMS (Micro-Electro-Mechanical Systems) resonator technology, while the CPPC7L-A7BP-8.0TS uses Crystal resonator technology. Both technologies deliver equivalent electrical performance within the specified parameters for this application. The choice between them is determined by the specific design requirements and availability.

Q: Are there any physical dimension differences that affect PCB design?

A: Both parts share identical footprint dimensions of 7.00mm x 5.00mm and use the same 4-SMD, No Lead package. However, the substitute part has a maximum seated height of 1.90mm compared to 1.00mm for the main part. Designs with height constraints must verify clearance above the substitute component.

Q: Does the substitute part meet current regulatory compliance standards?

A: Yes. The CPPC7L-A7BP-8.0TS carries ROHS3 and REACH compliance certifications, meeting current regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) export classifications.

Q: What is the availability status of each part?

A: The TA-8.000MBE-T is classified as Obsolete with 637 pieces in current inventory. The CPPC7L-A7BP-8.0TS is classified as Active with 1021 pieces in current inventory, providing superior long-term availability and manufacturing support.

Q: Are the frequency stability specifications identical?

A: Yes. Both parts specify ±50ppm frequency stability across the -40°C to 85°C operating temperature range, ensuring equivalent timing accuracy for applications requiring this specification.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided that PCB clearance above the component is verified. The substitute part's maximum seated height of 1.90mm (versus 1.00mm for the main part) must be confirmed against design constraints. All other electrical and mechanical parameters are equivalent.
