Engineering Selection Recommendations

The 510CBB3M68640AAGR from Skyworks Solutions Inc. is a direct functional equivalent to the obsolete 7W03670004. Selection of this substitute part is based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with Skyworks Solutions Inc., ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Electrical Equivalence: All critical electrical parameters match exactly: 3.6864 MHz frequency, CMOS output, 3.3V supply voltage, ±25ppm frequency stability, and -40°C to 85°C operating temperature range.

Mechanical Compatibility: The 4-SMD, no-lead package with 7.00mm x 5.00mm footprint ensures direct PCB compatibility. The maximum seated height of 0.071" (1.80mm) for the substitute is within acceptable tolerance relative to the original 0.056" (1.42mm), presenting no clearance or assembly issues.

Compliance Status: Both parts maintain RoHS compliance and MSL 1 moisture sensitivity rating, supporting equivalent handling and storage requirements.

Supply Availability: The substitute part is available in active inventory (1081 pcs) with standard tape & reel packaging, supporting both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 510CBB3M68640AAGR directly replace the 7W03670004 without PCB modifications?

A: Yes. The substitute part maintains identical electrical specifications and mechanical footprint (7.00mm x 5.00mm, 4-SMD no-lead package). Direct PCB replacement is possible without circuit redesign or layout changes.

Q: What is the significance of the height difference (1.42mm vs. 1.80mm)?

A: The 0.38mm height difference falls within standard PCB assembly tolerances and clearance margins. This variation does not affect component placement, solder reflow, or board-level clearance in typical applications.

Q: Why is the original 7W03670004 classified as obsolete?

A: Obsolete status indicates that TXC CORPORATION has discontinued production and support for this part. Substitute parts ensure design continuity and system support for existing applications.

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

A: No functional differences exist. Both parts provide identical CMOS output, enable/disable control, frequency stability, and operating temperature range. The substitute part includes specified maximum supply current (26mA), which was not provided for the original part.

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

A: The 510CBB3M68640AAGR is supplied in tape & reel (TR) format, the standard packaging for surface mount oscillators in production environments.

Q: Do both parts require identical handling and storage procedures?

A: Yes. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating and RoHS compliance, requiring identical moisture control, storage temperature, and handling protocols.

Q: Is the substitute part suitable for new designs?

A: Yes. The 510CBB3M68640AAGR is an active product with ongoing manufacturer support, making it suitable for both replacement applications and new design implementations.
