Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7W-3.6864MBE-T are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Frequency: 3.6864 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Physical Dimensions: 7.00mm x 5.00mm
• Mounting Type: Surface Mount
• Base Resonator: Crystal

Both identified substitute parts (CPPC7L-A7BP-3.6864TS and CPPC7LZA7BP-3.68640TS) from Cardinal Components Inc. meet all critical electrical parameters and mechanical specifications. These parts are manufactured under the FIPO™ CPP series and maintain active product status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

Both Cardinal Components Inc. substitute parts (CPPC7L-A7BP-3.6864TS and CPPC7LZA7BP-3.68640TS) are direct functional equivalents to the obsolete 7W-3.6864MBE-T. Selection between these two Cardinal options is based on inventory availability and packaging requirements, as they are electrically and mechanically identical.

Compliance Advantages of Substitute Parts:

• Active product status ensures continued manufacturer support and long-term availability
• ROHS3 compliance exceeds the RoHS compliance of the original part
• REACH Unaffected status provides additional regulatory assurance
• Tape & Reel packaging supports automated assembly processes

Physical Consideration: The substitute parts have a maximum seated height of 1.90mm compared to the original part's 1.42mm. This 0.48mm height difference must be verified against PCB layout constraints and enclosure clearances in the target application.

Frequently Asked Questions (FAQ)

Q: Can CPPC7L-A7BP-3.6864TS and CPPC7LZA7BP-3.68640TS be used interchangeably with the 7W-3.6864MBE-T?

A: Yes. Both Cardinal Components parts meet all critical electrical and mechanical parameters: 3.6864 MHz frequency, CMOS output, 3.3V supply, enable/disable function, ±50ppm stability, -40°C to 85°C operating range, and 4-SMD No Lead package with 7.00mm x 5.00mm footprint. The parts are pin-compatible and functionally equivalent.

Q: What is the difference between CPPC7L-A7BP-3.6864TS and CPPC7LZA7BP-3.68640TS?

A: Both parts are electrically and mechanically identical. The difference lies in part number designation only. Both are manufactured by Cardinal Components Inc. under the FIPO™ CPP series, share identical specifications, and are available in Tape & Reel packaging.

Q: Does the increased maximum supply current (25mA vs. 20mA) affect compatibility?

A: No. The substitute parts' maximum supply current of 25mA is higher than the original part's 20mA specification. This represents a less stringent requirement and does not impact compatibility. Designs operating within the original 20mA specification will function correctly with the substitute parts.

Q: Is the 0.48mm height difference (1.90mm vs. 1.42mm) a concern?

A: The height difference must be evaluated against specific PCB layout and enclosure design constraints. Verify clearance above the component location and confirm compatibility with any mechanical assemblies or covers in the target application.

Q: Are the substitute parts available in the same packaging as the original?

A: The substitute parts are supplied in Tape & Reel (TR) packaging, which is standard for automated assembly. The original part's packaging format was not specified in the available data. Tape & Reel packaging is compatible with standard pick-and-place equipment.

Q: What is the significance of ROHS3 compliance on the substitute parts?

A: ROHS3 compliance indicates adherence to the latest Restriction of Hazardous Substances directive requirements. This exceeds the RoHS compliance of the original part and ensures the substitute parts meet current environmental and regulatory standards.

Q: Can I mix inventory of the original and substitute parts in production?

A: Yes. Both parts are functionally equivalent and pin-compatible. However, verify that your assembly process and quality control procedures account for the slight height difference (1.90mm vs. 1.42mm) if both parts are used in the same production run.
