Parameter Comparison

Engineering Selection Recommendations

The SXO75C3A171-50.000M from Suntsu Electronics, Inc. is a direct functional equivalent to the obsolete 7W50000034. Selection of this substitute part is supported by the following engineering factors:

Product Status: The substitute part maintains active product status with Suntsu Electronics, ensuring ongoing availability and supply chain continuity compared to the obsolete TXC part.

Compliance Certifications: Both parts maintain equivalent regulatory compliance. The substitute achieves ROHS3 Compliant status, which supersedes the RoHS Compliant designation of the original part. Both parts carry REACH Unaffected and EAR99 ECCN classifications, indicating equivalent export and environmental compliance profiles.

Electrical and Mechanical Equivalence: All critical electrical parameters—frequency, output type, supply voltage, function, frequency stability, and operating temperature range—are identical between the two parts. Physical dimensions and package type are identical, ensuring direct PCB footprint compatibility.

Height Variance: The seated height of the substitute part (1.60mm) exceeds the original part (1.42mm) by 0.18mm. This variance remains within typical PCB assembly tolerances and does not affect electrical performance or standard assembly processes.

Supply Availability: The substitute part is available in significantly higher inventory (4347 Pcs) compared to the original part (1032 Pcs), providing improved procurement reliability.
