Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the 7W-64.000MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 64 MHz (exact match required)
• Output Configuration: CMOS
• Supply Voltage: 3.3V
• Enable/Disable Function: Present
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Physical Footprint: 7.00mm x 5.00mm

Allowable Variations:

• Supply Current (Max): Substitute may exceed main part specification (20mA) provided it does not exceed system power budget constraints
• Height (Seated): Substitute may vary within PCB assembly clearance limits
• Disable Mode Current: Substitute specifications may differ
• Product Status: Active substitutes are preferred for obsolete main parts
• Packaging Format: Tape & Reel acceptable for manufacturing environments

The identified substitute parts (510CBA64M0000AAGR and CPPLC7L-A7BR-64.0TS) satisfy all mandatory matching parameters and are classified as active products, providing long-term availability for production and field replacement applications.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

Both 510CBA64M0000AAGR (Skyworks Solutions) and CPPLC7L-A7BR-64.0TS (Cardinal Components) are active products suitable for replacing the obsolete 7W-64.000MBD-T. Selection between these two substitutes should be based on the following factors:

510CBA64M0000AAGR Selection Criteria:

• Active product status with established supply chain
• Maximum supply current of 26mA (6mA higher than original)
• Height of 1.80mm (0.38mm taller than original)
• Disable mode current specification of 18mA provided
• Compliance certifications not specified in available data

CPPLC7L-A7BR-64.0TS Selection Criteria:

• Active product status with established supply chain
• Maximum supply current of 25mA (5mA higher than original)
• Height of 1.90mm (0.48mm taller than original)
• ROHS3 compliance certification
• REACH Unaffected status confirmed
• Disable mode current of 50µA (lower power consumption in disabled state)

Compatibility Verification: Both substitutes maintain identical electrical specifications (frequency, output type, supply voltage, enable/disable function, frequency stability, and operating temperature range). Physical footprint compatibility (7.00mm x 5.00mm) is preserved. Height variations must be evaluated against specific PCB assembly clearance requirements. Supply current increases are acceptable provided system power budgets accommodate the additional current draw.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA64M0000AAGR directly replace the 7W-64.000MBD-T without PCB modifications?

A: Direct replacement is possible if PCB clearance accommodates the 1.80mm seated height (compared to 1.42mm original). The identical 7.00mm x 5.00mm footprint and 4-SMD, No Lead package ensure mechanical compatibility. Electrical compatibility is confirmed across all critical parameters.

Q: What is the impact of increased supply current in the substitute parts?

A: The 510CBA64M0000AAGR draws 26mA maximum and the CPPLC7L-A7BR-64.0TS draws 25mA maximum, compared to 20mA for the original part. This 5-6mA increase must be evaluated against system power supply capacity and thermal design. If the original design operated at or near the 20mA specification, power budget verification is required.

Q: Are there differences in disable mode power consumption?

A: Yes. The 510CBA64M0000AAGR specifies 18mA disable current, while the CPPLC7L-A7BR-64.0TS specifies 50µA disable current. For applications where the oscillator is frequently disabled, the Cardinal component offers significantly lower standby power consumption.

Q: Do the substitute parts meet the same compliance standards as the original?

A: Both substitutes share EAR99 ECCN classification and MSL 1 (Unlimited) moisture sensitivity rating with the original. The CPPLC7L-A7BR-64.0TS provides explicit ROHS3 and REACH Unaffected certifications. The 510CBA64M0000AAGR compliance status is not specified in available documentation.

Q: What is the frequency stability tolerance, and is it identical across all three parts?

A: All three parts (original and both substitutes) specify ±25ppm frequency stability across the -40°C to 85°C operating temperature range. This parameter is identical and does not differentiate the parts.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability is confirmed for electrical function and frequency specification. Physical height variations (1.42mm original vs. 1.80mm or 1.90mm substitutes) must be verified against PCB assembly clearance. Supply current increases must be evaluated against system power budgets. Once these mechanical and electrical constraints are confirmed, the parts are functionally interchangeable.

Q: Which substitute should be selected for new production designs?

A: Selection depends on specific application requirements. For standard applications with adequate power budget and clearance, either part is suitable. For power-constrained applications or designs with tight vertical clearance, evaluate the specific height and current requirements against your design constraints. For applications requiring explicit RoHS3 compliance documentation, the CPPLC7L-A7BR-64.0TS is the preferred choice.
