Engineering Selection Recommendations

The 510CBA6M00000AAGR from Skyworks Solutions Inc. is a direct functional equivalent to the obsolete 7W-6.000MBD-T. Selection of this substitute is supported by the following factors:

Compliance & Certification:

Both parts maintain RoHS Compliant status
Both parts carry REACH Unaffected designation
Both parts are classified under ECCN EAR99 and HTSUS 8542.39.0001

Product Status:

The substitute part (510CBA6M00000AAGR) holds Active product status, ensuring ongoing availability and manufacturer support
The original part (7W-6.000MBD-T) is Obsolete, making substitution necessary for continued supply

Electrical Equivalence:

All critical electrical parameters match exactly: frequency, output type, supply voltage, function, frequency stability, and operating temperature range
The substitute exhibits slightly higher maximum supply current (26mA vs. 20mA) and seated height (1.80mm vs. 1.42mm), both within acceptable design margins for standard applications

Physical Compatibility:

Identical package type, dimensions, and mounting method ensure PCB-level compatibility without layout modifications

The 510CBA6M00000AAGR is suitable for direct replacement in applications currently using the 7W-6.000MBD-T, provided that the higher current draw and increased height do not conflict with specific system constraints.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA6M00000AAGR be used as a direct drop-in replacement for the 7W-6.000MBD-T?

A: Yes. Both parts share identical frequency (6 MHz), output type (CMOS), supply voltage (3.3V), enable/disable function, frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and package dimensions (7.00mm x 5.00mm, 4-SMD No Lead). PCB layout and schematic connections require no modification.

Q: What are the differences between these two parts?

A: The primary differences are: (1) Manufacturer (TXC vs. Skyworks), (2) Product Status (Obsolete vs. Active), (3) Maximum supply current (20mA vs. 26mA), (4) Seated height (1.42mm vs. 1.80mm), and (5) Packaging format (Bulk vs. Tape & Reel). All differences are non-critical for standard applications.

Q: Does the higher current draw of the 510CBA6M00000AAGR affect system design?

A: The substitute draws a maximum of 26mA compared to 20mA for the original part. This 6mA difference is typically negligible in most 3.3V supply designs. Verify that your power supply and current distribution network can accommodate this specification.

Q: Is the increased seated height (1.80mm vs. 1.42mm) a concern?

A: The 0.38mm height increase is minimal and unlikely to cause clearance issues in standard PCB designs. Verify clearance in your specific application, particularly if the oscillator is located near other tall components or under a shielding enclosure.

Q: Are both parts RoHS compliant?

A: Yes. Both the 7W-6.000MBD-T and 510CBA6M00000AAGR are RoHS Compliant and REACH Unaffected, meeting environmental and regulatory requirements for most markets.

Q: What is the difference between Bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for small quantities and manual assembly. Tape & Reel (TR) packaging is designed for automated pick-and-place assembly and high-volume production. The component itself is identical; only the delivery format differs.

Q: Can I use the 510CBA6M00000AAGR in a design originally specified for the 7W-6.000MBD-T?

A: Yes. All electrical and mechanical parameters that determine functional compatibility are matched. No design changes are required.
