Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7W50000006 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 50 MHz (exact match required)
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±50ppm
• Operating Temperature Range: -10°C ~ 70°C (minimum)
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 7.00mm x 5.00mm
• Base Resonator: Crystal
• Type: XO (Standard)

The SXO75C3A171-50.000M manufactured by Suntsu Electronics, Inc. satisfies all mandatory matching parameters and is classified as an Active product, providing improved supply chain availability compared to the Obsolete 7W50000006.

Parameter Comparison

Engineering Selection Recommendations

The SXO75C3A171-50.000M is a direct functional equivalent to the 7W50000006 based on electrical and mechanical parameter equivalence. Selection of the Suntsu substitute is supported by the following factors:

Product Status: The SXO75C3A171-50.000M maintains Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The 7W50000006 Obsolete status creates supply risk and limits long-term sourcing options.

Compliance Certifications: Both components maintain equivalent regulatory compliance. The SXO75C3A171-50.000M achieves ROHS3 Compliant status (an advancement over RoHS Compliant), and both components are REACH Unaffected and classified as EAR99 for export control purposes.

Physical and Electrical Compatibility: All critical electrical parameters (frequency, output type, supply voltage, function, stability, and temperature range) are identical. Physical dimensions are identical (7.00mm x 5.00mm), with maximum seated height of 1.60mm for the substitute compared to 1.42mm for the original, representing a 0.18mm increase that remains within standard PCB assembly tolerances for 4-SMD, No Lead packages.

Supply Availability: The SXO75C3A171-50.000M demonstrates significantly higher inventory availability (4347 Pcs) compared to the 7W50000006 (890 Pcs), supporting production continuity and reducing procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3A171-50.000M be used as a direct replacement for the 7W50000006 in existing designs?

A: Yes. The SXO75C3A171-50.000M meets all mandatory electrical and mechanical parameters required for direct substitution. Frequency, output type, supply voltage, enable/disable function, frequency stability, operating temperature range, package type, and physical dimensions are identical. The maximum seated height difference of 0.18mm is within standard PCB assembly tolerances for surface mount components.

Q: What is the significance of the Obsolete status for the 7W50000006?

A: Obsolete status indicates that TXC CORPORATION has discontinued manufacturing and support for this component. This creates supply chain risk, limits availability for future production runs, and may result in increased procurement costs or extended lead times. Transitioning to an Active substitute ensures long-term design sustainability.

Q: Are there any compliance or regulatory differences between the two parts?

A: Both components are REACH Unaffected and classified as EAR99 for export control. The SXO75C3A171-50.000M achieves ROHS3 Compliant status, which represents an advancement over the RoHS Compliant status of the 7W50000006. Both meet current regulatory requirements for electronic component manufacturing and use.

Q: How does the 0.18mm difference in maximum seated height affect PCB assembly?

A: The SXO75C3A171-50.000M has a maximum seated height of 1.60mm compared to 1.42mm for the 7W50000006. This 0.18mm increase is within standard PCB assembly tolerances for 4-SMD, No Lead surface mount packages and does not require PCB layout modifications. Standard reflow soldering processes accommodate this variation.

Q: Is the supply current specification important for substitution?

A: The SXO75C3A171-50.000M specifies a maximum supply current of 25mA. The 7W50000006 does not provide this specification. For applications where supply current is a design constraint, the 25mA specification for the substitute should be verified against circuit requirements. In most standard applications, this specification does not impact substitution feasibility.

Q: What packaging format is used for the SXO75C3A171-50.000M?

A: The SXO75C3A171-50.000M is supplied in Bulk packaging, compared to the 7W50000006 which uses standard packaging. Both components use identical 4-SMD, No Lead package types suitable for automated PCB assembly processes.
