Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7W20000025 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 20 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -10°C ~ 70°C (minimum)
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 0.276" L x 0.197" W (7.00mm x 5.00mm)
• Base Resonator: Crystal

The substitute part SXO75C3C171-20.000M from Suntsu Electronics, Inc. meets all mandatory matching parameters and is therefore classified as a direct equivalent. The substitute maintains identical electrical specifications and mechanical compatibility while offering Active product status and improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The SXO75C3C171-20.000M from Suntsu Electronics, Inc. is a direct functional and mechanical equivalent to the 7W20000025. Selection of this substitute part is supported by the following factors:

Compliance and Certification: Both parts maintain REACH Unaffected status. The substitute part carries ROHS3 Compliant certification, which supersedes the RoHS Compliant status of the original part, ensuring compliance with current regulatory requirements.

Product Status: The substitute part holds Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete status of the 7W20000025.

Electrical and Mechanical Compatibility: All critical electrical parameters—frequency, output type, supply voltage, function, frequency stability, and operating temperature range—are identical. Physical dimensions and package configuration are equivalent, enabling direct board-level substitution without design modification.

Height Consideration: The substitute part exhibits a maximum seated height of 0.063" (1.60mm) compared to 0.056" (1.42mm) for the original part. This 0.007" (0.18mm) difference remains within typical PCB assembly tolerances and does not preclude substitution in standard applications.

Supply Availability: The substitute part demonstrates significantly higher inventory availability (4791 Pcs) compared to the original part (2900 Pcs), supporting production continuity and cost optimization.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3C171-20.000M be used as a direct replacement for the 7W20000025 without PCB modification?

A: Yes. The SXO75C3C171-20.000M is mechanically and electrically equivalent. Both parts share identical package configuration (4-SMD, No Lead), physical dimensions (7.00mm x 5.00mm), and all critical electrical specifications. Direct substitution on existing PCBs is supported without design changes.

Q: What is the significance of the height difference between the two parts?

A: The substitute part (SXO75C3C171-20.000M) has a maximum seated height of 0.063" (1.60mm) versus 0.056" (1.42mm) for the original part. This 0.18mm difference is within standard PCB assembly tolerances and does not impact functionality or board-level compatibility in typical applications.

Q: Are there any differences in supply current specifications?

A: The original part (7W20000025) does not specify maximum supply current. The substitute part (SXO75C3C171-20.000M) specifies 16mA maximum supply current. This documented specification provides additional design margin information and does not indicate incompatibility.

Q: How do the RoHS certifications compare?

A: The original part carries RoHS Compliant certification. The substitute part carries ROHS3 Compliant certification, which represents a more current regulatory standard. Both certifications confirm lead-free and hazardous substance compliance, with ROHS3 reflecting updated requirements.

Q: Is the substitute part suitable for new designs?

A: Yes. The SXO75C3C171-20.000M holds Active product status, ensuring ongoing manufacturer support, documentation availability, and supply chain reliability. This part is appropriate for both legacy system maintenance and new design implementations.

Q: What packaging options are available for the substitute part?

A: The substitute part (SXO75C3C171-20.000M) is available in Bulk packaging, suitable for production quantities and automated assembly processes.
