Parameter Comparison

Engineering Selection Recommendations

The SXO75C3C171-50.000M from Suntsu Electronics, Inc. is a direct substitute for the obsolete 7W-50.000MBA-T. Selection is based on the following engineering criteria:

Product Status: The SXO75C3C171-50.000M is classified as Active, ensuring ongoing availability and supply chain support, whereas the 7W-50.000MBA-T is Obsolete.

Compliance & Certifications: Both parts maintain equivalent regulatory compliance with REACH Unaffected status and EAR99 export classification. The SXO75C3C171-50.000M carries ROHS3 Compliant certification, which supersedes the RoHS Compliant status of the original part, providing enhanced environmental compliance.

Electrical & Mechanical Compatibility: All critical electrical parameters (frequency, output type, supply voltage, function, frequency stability, and operating temperature range) are identical. Package type, dimensions, and mounting configuration are equivalent, enabling direct PCB-level substitution without layout modifications.

Parameter Variations: The SXO75C3C171-50.000M exhibits a maximum supply current of 25mA compared to 20mA for the original part, and a maximum seated height of 1.60mm compared to 1.42mm. These variations remain within acceptable tolerances for standard surface mount assembly processes and do not impact functional performance in typical applications.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3C171-50.000M be used as a direct replacement for the 7W-50.000MBA-T without PCB modifications?

A: Yes. The SXO75C3C171-50.000M is mechanically and electrically compatible with the 7W-50.000MBA-T. Both parts share identical package dimensions (7.00mm x 5.00mm), 4-SMD No Lead configuration, and surface mount footprint. No PCB layout changes are required.

Q: What are the differences in supply current between these parts?

A: The 7W-50.000MBA-T specifies a maximum supply current of 20mA, while the SXO75C3C171-50.000M specifies 25mA. The Suntsu part has a higher maximum current specification. Designs must accommodate this higher current draw in power supply calculations.

Q: Are there height clearance considerations when substituting these parts?

A: The 7W-50.000MBA-T has a maximum seated height of 1.42mm, while the SXO75C3C171-50.000M has a maximum seated height of 1.60mm. The difference of 0.18mm must be verified against PCB assembly clearance requirements, particularly in applications with height-constrained enclosures or stacked component arrangements.

Q: Do both parts support Enable/Disable functionality?

A: Yes. Both the 7W-50.000MBA-T and SXO75C3C171-50.000M include Enable/Disable function, providing equivalent control capability for power management and clock gating applications.

Q: What is the frequency stability specification for both parts?

A: Both parts specify a frequency stability of ±25ppm across the operating temperature range of -10°C to 70°C, ensuring equivalent timing accuracy for applications requiring this stability level.

Q: Are there any compliance or certification differences?

A: Both parts are REACH Unaffected and carry EAR99 export classification. The SXO75C3C171-50.000M carries ROHS3 Compliant certification, which represents an enhanced environmental compliance standard compared to the RoHS Compliant status of the original part.

Q: What is the inventory status for these parts?

A: The 7W-50.000MBA-T is Obsolete with 707 pieces in stock. The SXO75C3C171-50.000M is Active with 6358 pieces in stock, providing reliable long-term supply availability.
