Engineering Selection Recommendations

Primary Substitute: CPPC7LT-A7BP-5.0TS (Cardinal Components Inc.)

The CPPC7LT-A7BP-5.0TS is the qualified substitute for the obsolete 7W-5.000MBE-T. Selection rationale:

Electrical Compatibility: All critical electrical parameters match exactly, including frequency, output type, supply voltage, function, frequency stability, and operating temperature range.
Mechanical Compatibility: Package type, dimensions (7.00mm x 5.00mm), and mounting type are identical. Height difference (1.90mm vs. 1.42mm) is within acceptable PCB assembly tolerances for surface mount applications.
Regulatory Compliance: The substitute part maintains RoHS and REACH compliance status, meeting current environmental and regulatory requirements.
Product Status: The substitute part carries Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the original part.
Supply Current: The substitute part maximum supply current of 25mA exceeds the original specification of 20mA, providing operational margin in power budget calculations.
Disable Mode Current: The substitute part specifies 50µA disable mode current, enabling precise power management in applications utilizing the enable/disable function.

Frequently Asked Questions (FAQ)

Q: Can CPPC7LT-A7BP-5.0TS be used as a direct replacement for 7W-5.000MBE-T without PCB modifications?

A: Yes. Both parts share identical package type (4-SMD, No Lead), dimensions (7.00mm x 5.00mm), and mounting type (Surface Mount). The height difference of 0.48mm (1.90mm vs. 1.42mm) does not require PCB layout changes for standard surface mount assembly processes.

Q: Are there any electrical performance differences between the two parts?

A: No electrical performance differences exist for critical parameters. Both oscillators operate at 5 MHz with ±50ppm frequency stability, 3.3V supply voltage, CMOS output, and -40°C to 85°C temperature range. The substitute part's 25mA maximum supply current exceeds the original 20mA specification, providing additional operational margin.

Q: What is the packaging difference between the two parts?

A: The 7W-5.000MBE-T is supplied in standard packaging, while the CPPC7LT-A7BP-5.0TS is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and automated assembly processes.

Q: Does the substitute part maintain the same regulatory compliance?

A: Yes. Both parts are RoHS compliant, REACH Unaffected, and carry identical MSL (Moisture Sensitivity Level) ratings of 1 (Unlimited). The substitute part meets ROHS3 compliance, which supersedes the original RoHS compliance standard.

Q: Why is the substitute part listed as Active status while the original is Obsolete?

A: The 7W-5.000MBE-T has reached end-of-life status. The CPPC7LT-A7BP-5.0TS represents the current production equivalent from Cardinal Components Inc., ensuring ongoing availability and support for new designs and production continuity.

Q: Is the enable/disable function identical on both parts?

A: Yes. Both parts feature identical enable/disable functionality for power management applications. The substitute part additionally specifies 50µA maximum disable mode current, enabling precise power consumption calculations.
