Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7W-10.000MBA-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 10 MHz (exact match required)
• Output Type: CMOS (electrical interface compatibility)
• Supply Voltage: 3.3V (circuit integration requirement)
• Function: Enable/Disable (operational feature requirement)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature Range: -10°C ~ 70°C (environmental operating window)
• Package Type: 4-SMD, No Lead (PCB footprint compatibility)
• Physical Dimensions: 7.00mm x 5.00mm (mechanical fit requirement)

The SXO75C3C171-10.000M from Suntsu Electronics, Inc. satisfies all mandatory matching parameters and qualifies as a direct substitute. This part maintains identical electrical performance specifications and physical form factor while offering active product status and improved supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The SXO75C3C171-10.000M is a qualified substitute for the obsolete 7W-10.000MBA-T based on the following engineering criteria:

Product Status Consideration: The 7W-10.000MBA-T is classified as obsolete. The SXO75C3C171-10.000M maintains active product status, ensuring long-term availability and continued manufacturer support.

Electrical Equivalence: All critical electrical parameters are identical: 10 MHz frequency, CMOS output, 3.3V supply voltage, enable/disable function, and ±25ppm frequency stability. The substitute part draws 16mA maximum supply current compared to 20mA for the original, representing improved power efficiency without functional compromise.

Compliance Alignment: Both parts maintain RoHS compliance (original: RoHS Compliant; substitute: ROHS3 Compliant), REACH unaffected status, and identical export classification (EAR99) and tariff codes (8542.39.0001).

Physical Compatibility: The substitute maintains identical footprint dimensions (7.00mm x 5.00mm) and package type (4-SMD, No Lead). The seated height difference of 0.18mm (1.42mm original vs. 1.60mm substitute) falls within typical PCB assembly tolerances and does not affect mechanical clearance in standard applications.

Operating Environment: Both parts operate across the identical temperature range (-10°C ~ 70°C), ensuring functional equivalence across all specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3C171-10.000M be used as a direct replacement for the 7W-10.000MBA-T without circuit modifications?

A: Yes. The substitute part maintains identical electrical specifications (frequency, output type, supply voltage, function, and frequency stability) and physical form factor. No circuit modifications are required for direct substitution.

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

A: The seated height difference (1.42mm vs. 1.60mm) is within standard PCB assembly tolerances and does not affect mechanical clearance in typical surface mount applications. This difference does not impact electrical performance or mechanical fit.

Q: Why is the substitute part drawing less current (16mA vs. 20mA)?

A: The lower maximum supply current of the substitute part represents improved power efficiency in the oscillator design. This does not affect functional compatibility and provides a secondary benefit of reduced power consumption in the application circuit.

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

A: Both parts maintain equivalent compliance status. The original is RoHS Compliant; the substitute is ROHS3 Compliant (an updated standard). Both are REACH unaffected, share identical export classification (EAR99), and carry the same tariff code (8542.39.0001).

Q: Is the SXO75C3C171-10.000M available for immediate procurement?

A: The substitute part is classified as active product status with 3235 pieces in new original stock, ensuring availability for procurement and ongoing system support.

Q: What parameters must remain identical for substitution to be valid?

A: Frequency (10 MHz), output type (CMOS), supply voltage (3.3V), function (enable/disable), frequency stability (±25ppm), operating temperature range (-10°C ~ 70°C), and package type (4-SMD, No Lead) must all match exactly. These parameters determine electrical and mechanical compatibility.
