Engineering Selection Recommendations

The 510CAA33M0000AAGR from Skyworks Solutions Inc. is a direct functional equivalent to the obsolete 7W33000039. Selection of this substitute is based on the following engineering criteria:

Product Status Consideration: The 7W33000039 is classified as Obsolete, whereas the 510CAA33M0000AAGR maintains Active product status. This ensures continued availability and manufacturer support for new production runs and field replacements.

Electrical Equivalence: Both parts operate identically across all specified electrical parameters: 33 MHz frequency, CMOS output, 3.3V supply voltage, Enable/Disable function, ±50ppm frequency stability, and -40°C to 85°C operating temperature range.

Mechanical Compatibility: Both components utilize identical 4-SMD, No Lead package footprints with 7.00mm x 5.00mm dimensions. The 510CAA33M0000AAGR seated height is 0.071" (1.80mm) compared to 0.056" (1.42mm) for the 7W33000039, a difference of 0.015" (0.38mm). This height differential must be evaluated within the context of specific PCB assembly clearance requirements and component placement constraints.

Compliance Alignment: Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The 7W33000039 is RoHS Compliant; RoHS status for the 510CAA33M0000AAGR is not specified in available data. Both components feature MSL 1 (Unlimited) moisture sensitivity rating.

Supply Chain Availability: The 510CAA33M0000AAGR is available in Tape & Reel (TR) packaging format, supporting automated assembly processes. The 7W33000039 is available in bulk packaging with 815 pieces in stock; the 510CAA33M0000AAGR has 673 pieces in stock.

Frequently Asked Questions (FAQ)

Q: Can the 510CAA33M0000AAGR be used as a direct replacement for the 7W33000039 in existing designs?

A: Yes. The 510CAA33M0000AAGR meets all electrical and mechanical specifications of the 7W33000039. Both components share identical frequency (33 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), frequency stability (±50ppm), operating temperature range (-40°C to 85°C), and package footprint (4-SMD, No Lead, 7.00mm x 5.00mm). The seated height difference of 0.015" (0.38mm) must be evaluated for PCB clearance compatibility in specific applications.

Q: What is the significance of the seated height difference between these two parts?

A: The 7W33000039 has a maximum seated height of 0.056" (1.42mm), while the 510CAA33M0000AAGR has a maximum seated height of 0.071" (1.80mm). This 0.015" (0.38mm) difference may impact designs with tight vertical clearance constraints, such as applications with low-profile enclosures or densely stacked component arrangements. PCB layout and assembly clearance must be verified for the specific application.

Q: Are there any differences in supply current specifications between these oscillators?

A: The 7W33000039 does not specify maximum supply current in available documentation. The 510CAA33M0000AAGR specifies a maximum supply current of 26mA during normal operation and 18mA during disable mode. These specifications should be incorporated into power budget calculations for the 510CAA33M0000AAGR.

Q: What is the difference between bulk and Tape & Reel packaging for these components?

A: The 7W33000039 is supplied in bulk packaging format, suitable for manual handling and small-quantity applications. The 510CAA33M0000AAGR is supplied in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly equipment and high-volume production environments. Selection between these packaging formats depends on manufacturing process requirements and production volume.

Q: Are both parts RoHS compliant?

A: The 7W33000039 is explicitly marked as RoHS Compliant. RoHS compliance status for the 510CAA33M0000AAGR is not specified in available technical documentation.
