Parameter Comparison

Engineering Selection Recommendations

The 510CBA70M0000AAGR from Skyworks Solutions Inc. is a direct functional equivalent for the obsolete 7W-70.000MBD-T. Both parts share identical electrical specifications across frequency, output type, supply voltage, enable/disable functionality, frequency stability, and operating temperature range. Both parts are housed in the same 4-SMD, no-lead package with matching 7.00mm x 5.00mm footprint dimensions.

The substitute part carries active product status from Skyworks Solutions Inc., ensuring continued manufacturing support, availability, and technical documentation. Both parts maintain RoHS compliance and MSL 1 moisture sensitivity rating, satisfying environmental and reliability requirements.

The substitute part exhibits a maximum supply current of 26mA compared to the original part's 20mA specification. This represents a higher current draw and must be evaluated within the context of the application's power budget and thermal management design. The substitute part's maximum seated height of 1.80mm exceeds the original part's 1.42mm specification by 0.38mm. PCB layout and enclosure clearance must be verified to accommodate this dimensional difference.

The substitute part is available in Tape & Reel packaging format, suitable for automated assembly processes. Selection of the 510CBA70M0000AAGR supports long-term supply chain continuity for designs currently utilizing the obsolete 7W-70.000MBD-T.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA70M0000AAGR directly replace the 7W-70.000MBD-T without circuit modification?

A: The 510CBA70M0000AAGR meets all critical electrical parameters required for direct substitution: 70 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±25ppm stability, and -40°C to 85°C operating range. The package footprint is identical at 7.00mm x 5.00mm. No circuit modification is required from an electrical standpoint. However, the substitute part's maximum seated height of 1.80mm versus 1.42mm for the original part must be verified against PCB layout and enclosure clearance constraints.

Q: What is the significance of the higher maximum supply current in the substitute part?

A: The 510CBA70M0000AAGR specifies a maximum supply current of 26mA compared to the 7W-70.000MBD-T's 20mA. This 6mA difference represents the upper limit of current consumption under specified operating conditions. The actual operating current may be lower. Applications with tight power budgets or thermal constraints must evaluate whether this higher specification impacts system performance, power dissipation, or battery life.

Q: Are both parts RoHS compliant?

A: Both the 7W-70.000MBD-T and 510CBA70M0000AAGR are RoHS compliant. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage, handling, or assembly.

Q: What packaging formats are available for the substitute part?

A: The 510CBA70M0000AAGR is supplied in Tape & Reel (TR) packaging format, standard for automated surface mount assembly processes. The original 7W-70.000MBD-T packaging format is not specified in the provided data.

Q: Is the substitute part actively manufactured?

A: The 510CBA70M0000AAGR carries active product status from Skyworks Solutions Inc., indicating ongoing manufacturing support and availability. The original 7W-70.000MBD-T is classified as obsolete, making the active substitute part the recommended choice for new designs and ongoing production support.

Q: What is the physical footprint compatibility between these parts?

A: Both parts utilize identical 4-SMD, no-lead package geometry with 7.00mm length and 5.00mm width dimensions. PCB land patterns and solder pad layouts are compatible. The substitute part's maximum seated height of 1.80mm is 0.38mm taller than the original part's 1.42mm specification. Verify clearance above the component to ensure compatibility with enclosure design, shielding, or adjacent components.
