Key Parameters

Substitute Part Grouping Explanation

Substitution of the TA-49.152MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 49.152 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Package Dimensions: 7.00mm x 5.00mm
• Moisture Sensitivity Level: MSL 1

The CPPC7LZ-A7BR-49.152TS from Cardinal Components Inc. meets all mandatory matching parameters and qualifies as a direct substitute. While the base resonator technology differs (Crystal vs. MEMS), both implementations deliver identical electrical performance within the specified operating envelope.

Parameter Comparison

*Note: The CPPC7LZ-A7BR-49.152TS seated height of 1.90mm exceeds the TA-49.152MBD-T specification of 1.00mm. PCB layout clearance must be verified before substitution.

Engineering Selection Recommendations

Primary Substitute: CPPC7LZ-A7BR-49.152TS

The CPPC7LZ-A7BR-49.152TS is the qualified substitute for the obsolete TA-49.152MBD-T. Selection is based on:

1. Product Status: The TA-49.152MBD-T is Obsolete. The CPPC7LZ-A7BR-49.152TS maintains Active status, ensuring long-term availability and manufacturing support.

2. Electrical Equivalence: All critical electrical parameters match exactly, including frequency, output type, supply voltage, function, stability, temperature range, and current specifications.

3. Package Compatibility: Both components use identical 4-SMD, No Lead packages with matching 7.00mm x 5.00mm footprints, enabling direct PCB footprint compatibility.

4. Compliance: The CPPC7LZ-A7BR-49.152TS carries ROHS3 Compliance and REACH Unaffected certifications, meeting modern regulatory requirements.

5. Physical Consideration: The substitute part has a maximum seated height of 1.90mm compared to the original 1.00mm. Verify PCB clearance in the component mounting area before implementation.

6. Resonator Technology: While the substitute uses Crystal-based resonance versus the original MEMS technology, both deliver identical performance within the specified operating envelope and frequency stability.

Frequently Asked Questions (FAQ)

Q: Can the CPPC7LZ-A7BR-49.152TS be used as a direct replacement for the TA-49.152MBD-T?

A: Yes. The CPPC7LZ-A7BR-49.152TS meets all mandatory electrical and mechanical parameters. The primary consideration is the increased seated height (1.90mm vs. 1.00mm), which requires verification of PCB clearance in the component mounting area.

Q: What is the difference between MEMS and Crystal-based oscillators in this application?

A: Both technologies deliver identical electrical performance for this 49.152 MHz application. The MEMS-based TA-49.152MBD-T and Crystal-based CPPC7LZ-A7BR-49.152TS provide the same frequency stability (±25ppm), output type (CMOS), and operating characteristics within the specified temperature range.

Q: Are there any compliance differences between the two parts?

A: The CPPC7LZ-A7BR-49.152TS includes ROHS3 Compliance and REACH Unaffected certifications. The original TA-49.152MBD-T compliance documentation is not provided in the available data. Verify compliance requirements for your specific application.

Q: What is the impact of the height difference on PCB design?

A: The CPPC7LZ-A7BR-49.152TS has a maximum seated height of 1.90mm, compared to 1.00mm for the TA-49.152MBD-T. If the original design has minimal clearance above the component, the additional 0.90mm height may require PCB layout modification or component repositioning.

Q: Is the packaging format the same for both parts?

A: The TA-49.152MBD-T uses standard packaging (not specified in detail). The CPPC7LZ-A7BR-49.152TS is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.

Q: What is the disable current specification for the TA-49.152MBD-T?

A: The disable current specification for the TA-49.152MBD-T is not provided in the available technical data. The CPPC7LZ-A7BR-49.152TS specifies 50µA maximum disable current. If disable current is critical for your application, contact the component manufacturer for TA-49.152MBD-T specifications.

Q: Can I use inventory of the TA-49.152MBD-T alongside the CPPC7LZ-A7BR-49.152TS in production?

A: Yes. Both parts are electrically equivalent and use identical PCB footprints. However, verify that PCB clearance accommodates the taller CPPC7LZ-A7BR-49.152TS component if mixed inventory is used in the same design revision.
