Parameter Comparison

Engineering Selection Recommendations

Both the 7C-8.000MBB-T and CPPC5LZ-A3B6-8.0TS are Active products with full regulatory compliance. Selection between these parts should be based on the following factors:

7C-8.000MBB-T (TXC CORPORATION):

• Tighter frequency stability specification (±50ppm)
• Narrower operating temperature range (-10°C ~ 70°C)
• Higher maximum supply current (30mA)
• RoHS Compliant certification

CPPC5LZ-A3B6-8.0TS (Cardinal Components Inc.):

• Wider operating temperature range (-55°C ~ 125°C)
• Lower maximum supply current (25mA)
• Specified disable mode current (50µA)
• Reduced seated height (1.30mm vs 1.40mm)
• ROHS3 Compliant certification

Both parts meet identical electrical and mechanical interface requirements. Selection depends on application-specific requirements for temperature range, power consumption, and regulatory compliance level.

Frequently Asked Questions (FAQ)

Q: Can the CPPC5LZ-A3B6-8.0TS directly replace the 7C-8.000MBB-T on an existing PCB?

A: Yes. Both parts share identical package type (4-SMD, No Lead), physical dimensions (5.00mm x 3.20mm), and mounting type (Surface Mount). The seated height difference (1.30mm vs 1.40mm) is within typical PCB assembly tolerances and does not affect placement or functionality.

Q: What are the key electrical differences between these oscillators?

A: The primary differences are frequency stability (±50ppm vs ±100ppm), operating temperature range (-10°C ~ 70°C vs -55°C ~ 125°C), and maximum supply current (30mA vs 25mA). The CPPC5LZ-A3B6-8.0TS provides specified disable mode current (50µA), while the 7C-8.000MBB-T does not specify this parameter.

Q: Are both parts RoHS compliant?

A: Yes. The 7C-8.000MBB-T is RoHS Compliant, and the CPPC5LZ-A3B6-8.0TS is ROHS3 Compliant. Both meet environmental compliance requirements.

Q: Which part should I select for applications requiring extended temperature operation?

A: The CPPC5LZ-A3B6-8.0TS supports -55°C ~ 125°C operating temperature, compared to -10°C ~ 70°C for the 7C-8.000MBB-T. Selection depends on your application's temperature requirements.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the 7C-8.000MBB-T and CPPC5LZ-A3B6-8.0TS have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the significance of the frequency stability specification difference?

A: The 7C-8.000MBB-T specifies ±50ppm frequency stability, while the CPPC5LZ-A3B6-8.0TS specifies ±100ppm. Applications requiring tighter frequency tolerance should use the 7C-8.000MBB-T. Applications with relaxed frequency tolerance requirements can use either part.
