Mandatory Matching Parameters:

• Frequency: 72 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
• Base Resonator: Crystal

The 510CBA72M0000AAGR manufactured by Skyworks Solutions Inc. meets all mandatory matching parameters and qualifies as a direct substitute. This part maintains electrical and mechanical compatibility while offering active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The 510CBA72M0000AAGR is a qualified substitute for the obsolete 7W-72.000MBD-T based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match exactly, including frequency (72 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±25ppm), and operating temperature range (-40°C ~ 85°C).

Mechanical Compatibility: Both parts share identical package type (4-SMD, No Lead) and footprint dimensions (7.00mm x 5.00mm), ensuring direct PCB layout compatibility. The substitute part has a maximum seated height of 1.80mm compared to 1.42mm for the original part; this 0.38mm difference must be evaluated against specific board clearance requirements.

Supply Current Consideration: The substitute part specifies a maximum supply current of 26mA during operation, compared to 20mA for the original part. This 6mA increase must be evaluated within the context of the system's power budget and supply rail capacity.

Product Status and Compliance: The substitute part maintains active product status with Skyworks Solutions Inc., ensuring ongoing availability and support. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, maintaining regulatory consistency.

Regulatory Alignment: The original part is RoHS Compliant. The substitute part's RoHS status is not specified in the provided data; compliance verification with the supplier is recommended prior to final design release.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA72M0000AAGR be used as a direct replacement for the 7W-72.000MBD-T on existing PCBs?

A: Yes, the 510CBA72M0000AAGR is electrically and mechanically compatible for direct substitution. Both parts use identical 4-SMD, No Lead packages with 7.00mm x 5.00mm footprints. However, the substitute part has a maximum seated height of 1.80mm versus 1.42mm for the original; verify that board clearance accommodates this 0.38mm height difference.

Q: What are the key electrical differences between these two parts?

A: The electrical specifications are equivalent across all critical parameters: frequency (72 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±25ppm), and operating temperature range (-40°C ~ 85°C). The substitute part specifies a maximum supply current of 26mA during operation and 18mA in disable mode, compared to 20mA maximum for the original part. Evaluate the 6mA increase against your system's power budget.

Q: Are there any compliance or regulatory differences?

A: Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The original part is specified as RoHS Compliant. The substitute part's RoHS compliance status is not provided in the available data; contact the supplier to confirm compliance status before final design release.

Q: What is the packaging format for the substitute part?

A: The 510CBA72M0000AAGR is supplied in Tape & Reel (TR) format, which is standard for high-volume production. The original part's packaging format is not specified in the available data.

Q: Why is the original 7W-72.000MBD-T classified as obsolete?

A: The 7W-72.000MBD-T is listed as obsolete by TXC CORPORATION. The 510CBA72M0000AAGR maintains active product status with Skyworks Solutions Inc., ensuring continued availability and technical support for new designs and production continuity.

Q: Are there any thermal or environmental considerations for substitution?

A: Both parts operate across the identical temperature range of -40°C ~ 85°C and share Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements. No additional thermal or environmental considerations apply to the substitution.
