Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TA-49.152MDD-T are identified based on strict parameter matching across electrical and mechanical specifications. The primary substitution criteria are:

Critical Matching Parameters:

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

Substitution Categories:

Direct Substitute (Electrical Equivalent): 510KBA49M1520AAGR by Skyworks Solutions Inc. maintains identical electrical specifications including 1.8V supply voltage, matching all critical parameters without functional deviation.

Similar Substitute (Voltage Variant): CPPC7LZ-A7BR-49.152TS by Cardinal Components Inc. provides functional equivalence with identical frequency, output type, package, and temperature range. This part operates at 3.3V supply voltage, requiring circuit-level voltage compatibility assessment before implementation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Option):

The 510KBA49M1520AAGR from Skyworks Solutions Inc. is the preferred direct substitute. This part maintains identical electrical specifications including 1.8V supply voltage, CMOS output, Enable/Disable function, and ±25ppm frequency stability. The component is currently in Active product status with 684 units available in inventory. Physical compatibility is confirmed through matching package type (4-SMD, No Lead) and footprint dimensions (7.00mm x 5.00mm). The increased seated height (1.80mm versus 1.00mm) requires PCB clearance verification but does not affect electrical performance. Both parts share identical ECCN (EAR99) and HTSUS classifications.

For Voltage-Compatible Applications:

The CPPC7LZ-A7BR-49.152TS from Cardinal Components Inc. serves as a functional equivalent for applications where 3.3V supply voltage is available or can be accommodated. This part maintains all critical frequency, output type, package, and temperature specifications. The component is Active with 642 units in inventory. Implementation requires confirmation that the 3.3V supply voltage is compatible with the circuit design. This part includes RoHS3 compliance and REACH Unaffected status certifications. The seated height of 1.90mm requires PCB clearance assessment.

Compliance Considerations:

All three parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring consistent export and tariff treatment. The Cardinal Components part provides additional RoHS3 and REACH documentation for applications with enhanced environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 510KBA49M1520AAGR directly replace the TA-49.152MDD-T without circuit modifications?

A: Yes. The 510KBA49M1520AAGR maintains identical electrical specifications including 1.8V supply voltage, CMOS output, Enable/Disable function, and ±25ppm frequency stability. Physical compatibility is confirmed through matching package type and footprint dimensions. The increased seated height (1.80mm) requires PCB clearance verification but does not affect electrical functionality.

Q: What is the key difference between the Skyworks and Cardinal substitute parts?

A: The primary difference is supply voltage. The Skyworks 510KBA49M1520AAGR operates at 1.8V (matching the original part), while the Cardinal CPPC7LZ-A7BR-49.152TS operates at 3.3V. All other electrical parameters including frequency, output type, function, and frequency stability are identical. Selection depends on circuit voltage availability.

Q: Are there any physical compatibility concerns with the substitute parts?

A: The substitute parts maintain identical footprint dimensions (7.00mm x 5.00mm) and package type (4-SMD, No Lead), ensuring PCB layout compatibility. However, seated heights differ: the original part measures 1.00mm maximum, the Skyworks part 1.80mm, and the Cardinal part 1.90mm. Verify adequate PCB clearance above the component before implementation.

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

A: The original TA-49.152MDD-T uses a MEMS-based resonator, while both substitute parts use crystal-based resonators. Both technologies deliver identical frequency stability (±25ppm) and operating characteristics for this application. The resonator type does not affect electrical compatibility or performance in this frequency and stability class.

Q: Are the substitute parts currently available?

A: Yes. The Skyworks 510KBA49M1520AAGR has 684 units in inventory with Active product status. The Cardinal CPPC7LZ-A7BR-49.152TS has 642 units in inventory with Active product status. Both parts are available for immediate procurement.

Q: Do the substitute parts have the same environmental compliance certifications?

A: All three parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The Cardinal Components part provides additional RoHS3 Compliant and REACH Unaffected certifications. The Skyworks part does not list these additional certifications in the provided specifications.

Q: What is the Moisture Sensitivity Level (MSL) for the substitute parts?

A: All three parts, including both substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
