Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7C-8.000MBA-T is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 8 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Package Type: 4-SMD, No Lead
• Package Dimensions: 5.00mm x 3.20mm (L x W)
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Frequency Stability: Substitute may have wider tolerance (±100ppm vs. ±25ppm)
• Operating Temperature Range: Substitute may have extended range (-55°C ~ 125°C vs. -10°C ~ 70°C)
• Current Supply (Max): Substitute may have lower maximum current (25mA vs. 30mA)
• Height - Seated (Max): Substitute may have different height within PCB assembly constraints (1.30mm vs. 1.40mm)

The CPPC5LZ-A3B6-8.0TS from Cardinal Components Inc. meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

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

Select 7C-8.000MBA-T when:

• Tighter frequency stability (±25ppm) is required
• Operating environment is limited to -10°C ~ 70°C
• Maximum supply current specification of 30mA is acceptable

Select CPPC5LZ-A3B6-8.0TS when:

• Extended operating temperature range (-55°C ~ 125°C) is required
• Lower maximum supply current (25mA) is beneficial for power-constrained applications
• Disable mode current specification (50µA) is a design requirement
• ROHS3 compliance is specifically mandated

Both parts are RoHS Compliant and REACH Unaffected, suitable for commercial and industrial applications. Identical package dimensions and mounting type ensure PCB-level compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can CPPC5LZ-A3B6-8.0TS replace 7C-8.000MBA-T in existing designs?

A: Yes. Both parts share identical frequency (8 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), and package dimensions (5.00mm x 3.20mm, 4-SMD No Lead). No PCB modifications are required. The substitute has a 0.10mm lower seated height (1.30mm vs. 1.40mm), which does not affect assembly or clearance in standard applications.

Q: What are the differences in frequency stability?

A: The 7C-8.000MBA-T specifies ±25ppm frequency stability, while the CPPC5LZ-A3B6-8.0TS specifies ±100ppm. Applications requiring tighter frequency tolerance should retain the original part. Applications with relaxed frequency tolerance requirements can use the substitute.

Q: Does the operating temperature range difference affect substitution?

A: The CPPC5LZ-A3B6-8.0TS operates across -55°C ~ 125°C, compared to -10°C ~ 70°C for the 7C-8.000MBA-T. If the application operates within -10°C ~ 70°C, both parts are functionally equivalent. If extended temperature operation is required, the substitute provides additional capability.

Q: Are there supply current differences?

A: The 7C-8.000MBA-T specifies 30mA maximum supply current. The CPPC5LZ-A3B6-8.0TS specifies 25mA maximum supply current. Both values are typical for 8 MHz CMOS oscillators. The substitute's lower maximum current may provide marginal power savings in battery-powered applications.

Q: What is the significance of the 50µA disable current specification?

A: The CPPC5LZ-A3B6-8.0TS specifies 50µA maximum current in Disable mode. This parameter is not provided for the 7C-8.000MBA-T. For applications requiring precise disable-mode power consumption calculations, the substitute provides explicit specification.

Q: Are both parts suitable for high-reliability applications?

A: Both parts are Active products with RoHS compliance and MSL 1 (Unlimited) moisture sensitivity rating. The 7C-8.000MBA-T is RoHS Compliant; the CPPC5LZ-A3B6-8.0TS is ROHS3 Compliant. Both are REACH Unaffected. Selection should be based on specific application reliability requirements and regulatory mandates.
