Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7W-32.000MBD-T is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 32 MHz
• Output: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±25ppm
• Operating Temperature: -40°C ~ 85°C
• Package/Case: 4-SMD, No Lead
• Physical Dimensions: 7.00mm x 5.00mm
• Moisture Sensitivity Level: MSL 1

All identified substitute parts meet these criteria. Variations in maximum supply current, disabled-state current consumption, and seated height do not preclude substitution, as these parameters fall within acceptable operational tolerances for this oscillator category. All substitute parts are classified as active products with current manufacturing status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CPPC7L-A7BR-32.0TS (Cardinal Components Inc.)

The CPPC7L-A7BR-32.0TS is the recommended primary substitute. This part maintains full electrical and mechanical compatibility with the 7W-32.000MBD-T while offering active product status and ROHS3 compliance. The part features superior disabled-state current consumption (50µA versus unspecified on the original), reducing power draw during standby operation. Inventory availability of 1055 units ensures supply continuity.

Secondary Substitutes: CPPC7LT-A7BR-32.0TS and CPPC7LZ-A7BR-32.0TS (Cardinal Components Inc.)

Both CPPC7LT-A7BR-32.0TS and CPPC7LZ-A7BR-32.0TS are functionally equivalent alternatives within the FIPO™ CPP series. These parts share identical electrical specifications and physical dimensions with CPPC7L-A7BR-32.0TS. Selection between these variants should be based on specific application requirements and internal design documentation.

Tertiary Substitute: CPPLC7L-A7BR-32.0TS (Cardinal Components Inc.)

The CPPLC7L-A7BR-32.0TS represents the FIPO™ CPPL series variant. This part maintains full compatibility and offers 992 units in inventory. The CPPL designation indicates a different internal design variant within Cardinal's product line.

Alternative Substitute: 510CBA32M0000AAGR (Skyworks Solutions Inc.)

The 510CBA32M0000AAGR from Skyworks Solutions Inc. (Si510 series) provides a cross-manufacturer alternative. This part meets all electrical and mechanical requirements. The maximum supply current specification of 26mA exceeds the original 20mA rating; however, this represents a conservative design margin and does not preclude substitution. Disabled-state current consumption is specified at 18mA.

All substitute parts are classified as active products with current manufacturing status, ensuring availability for both new production and field replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 7W-32.000MBD-T be directly replaced with any of these substitute parts?

A: Yes. All identified substitute parts meet the mandatory electrical and mechanical parameters: 32 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±25ppm stability, -40°C to 85°C operating range, 4-SMD no-lead package, and 7.00mm x 5.00mm footprint. Direct pin-for-pin and footprint compatibility is confirmed.

Q: What is the significance of the height difference between the original part (1.42mm) and substitute parts (1.80mm to 1.90mm)?

A: The seated height variation falls within acceptable tolerances for surface mount assembly processes. The substitute parts' increased height does not affect electrical performance or PCB layout compatibility. Verification with assembly equipment specifications is recommended for high-volume production environments.

Q: Are there compliance differences between the original and substitute parts?

A: The original 7W-32.000MBD-T is RoHS Compliant. All Cardinal Components substitutes (CPPC7L-A7BR-32.0TS, CPPC7LT-A7BR-32.0TS, CPPC7LZ-A7BR-32.0TS, CPPLC7L-A7BR-32.0TS) are ROHS3 Compliant, representing enhanced environmental compliance. The Skyworks 510CBA32M0000AAGR compliance status is not specified in available documentation.

Q: What is the difference between the Cardinal Components variants (CPPC7L, CPPC7LT, CPPC7LZ, CPPLC7L)?

A: All variants maintain identical electrical specifications and physical dimensions. The designations reflect different internal design implementations within Cardinal's FIPO™ product families. Selection should be based on application-specific requirements and design validation protocols.

Q: Which substitute part offers the best power efficiency in disabled mode?

A: The Cardinal Components parts (CPPC7L-A7BR-32.0TS, CPPC7LT-A7BR-32.0TS, CPPC7LZ-A7BR-32.0TS, CPPLC7L-A7BR-32.0TS) offer superior disabled-state current consumption at 50µA. The Skyworks 510CBA32M0000AAGR specifies 18mA in disabled mode. For applications requiring minimal standby power consumption, Cardinal Components variants are preferred.

Q: Is the increased maximum supply current (25-26mA) of substitute parts a concern?

A: No. The substitute parts' maximum supply current specifications (25mA for Cardinal variants, 26mA for Skyworks) represent conservative design margins above the original 20mA specification. These values indicate the maximum current the device will draw under worst-case conditions and do not indicate higher typical operating current. Circuit design should accommodate these maximum ratings.

Q: What packaging format is available for these substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) format, standard for high-volume surface mount assembly. The original part's packaging format is not specified in available documentation.

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

A: Yes, for designs currently using the 7W-32.000MBD-T. All substitute parts are pin-compatible and footprint-compatible. No PCB layout modifications are required. Thermal and electrical performance characteristics remain within the original design envelope.
