Engineering Selection Recommendations

Primary Substitute: SXO75C3C171-24.000M (Suntsu Electronics, Inc.)

The SXO75C3C171-24.000M is the direct functional equivalent for the obsolete 7W-24.000MBA-T. Selection of this substitute is supported by the following engineering factors:

Product Status: The substitute part is classified as active product status, ensuring long-term availability, continued manufacturing support, and stable supply chain access compared to the obsolete 7W-24.000MBA-T.

Electrical Equivalence: All critical electrical parameters match exactly: 24 MHz frequency, CMOS output with enable/disable function, 3.3V supply voltage, ±25ppm frequency stability, and -10°C to 70°C operating temperature range.

Current Consumption: The SXO75C3C171-24.000M operates at a maximum supply current of 16mA, which is lower than the 7W-24.000MBA-T specification of 20mA. This represents improved power efficiency and is compatible with existing circuit designs.

Package and Footprint: Both parts utilize identical 4-SMD, No Lead surface mount packages with matching 7.00mm x 5.00mm footprint dimensions, enabling direct PCB layout compatibility.

Physical Height: The SXO75C3C171-24.000M maximum seated height is 1.60mm compared to 1.42mm for the original part. This 0.18mm difference is within typical PCB assembly tolerances and does not impact board-level clearance or component placement.

Regulatory Compliance: Both parts maintain RoHS compliance (ROHS3 for the substitute represents the current standard) and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3C171-24.000M be used as a direct replacement for the 7W-24.000MBA-T without PCB modifications?

A: Yes. Both parts share identical footprint dimensions (7.00mm x 5.00mm) and 4-SMD, No Lead package configuration. No PCB layout changes are required for component substitution.

Q: What is the significance of the 0.18mm height difference between the two parts?

A: The SXO75C3C171-24.000M has a maximum seated height of 1.60mm versus 1.42mm for the 7W-24.000MBA-T. This difference is within standard PCB assembly process tolerances and does not affect component clearance, solder reflow profiles, or board-level functionality.

Q: Does the lower supply current of the SXO75C3C171-24.000M (16mA vs. 20mA) affect circuit design?

A: No. The substitute part's lower maximum supply current is compatible with existing designs. Circuits designed for the 20mA specification will operate correctly with the 16mA part, resulting in improved power efficiency.

Q: Are the frequency stability and operating temperature specifications identical?

A: Yes. Both parts specify ±25ppm frequency stability and operate across the -10°C to 70°C temperature range. Electrical performance characteristics are equivalent.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the current RoHS 3 directive standard (2011/65/EU as amended), which supersedes earlier RoHS versions. Both designations indicate full lead-free and hazardous substance compliance. The substitute part meets the current regulatory standard.

Q: Is the enable/disable function identical on both parts?

A: Yes. Both the 7W-24.000MBA-T and SXO75C3C171-24.000M provide enable/disable functionality with 3.3V supply voltage operation. Pin configuration and functional behavior are equivalent.

Q: Why is the 7W-24.000MBA-T classified as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions. The active status of the SXO75C3C171-24.000M provides a viable long-term alternative for continued design support and production requirements.
