Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7WA2502008 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Frequency: 125 MHz (exact match required)
• Output Type: CMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm × 5.00mm (exact match required)

The SXO75C3A071-125.000M from Suntsu Electronics, Inc. meets all critical electrical and mechanical parameters, making it a direct functional equivalent for the obsolete 7WA2502008.

Parameter Comparison

Engineering Selection Recommendations

The SXO75C3A071-125.000M is the direct equivalent substitute for the obsolete 7WA2502008. Selection is based on the following engineering factors:

Electrical Compatibility: Both parts operate at identical frequency (125 MHz), output type (CMOS), supply voltage (3.3V), and frequency stability (±50ppm). Enable/Disable functionality is preserved across both components.

Mechanical Compatibility: Physical dimensions and package type are identical (7.00mm × 5.00mm, 4-SMD No Lead). The maximum seated height difference (1.42mm vs. 1.60mm) is within typical PCB assembly tolerances and does not affect board-level compatibility.

Compliance Status: The SXO75C3A071-125.000M carries ROHS3 Compliant certification, representing an enhanced compliance level compared to the original RoHS Compliant designation. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Supply Chain Advantage: The substitute part is currently in active production status with 3315 pieces in stock, compared to the obsolete status of the original part with limited remaining inventory (825 pieces).

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3A071-125.000M be used as a direct replacement for the 7WA2502008 without circuit modifications?

A: Yes. The SXO75C3A071-125.000M is electrically and mechanically equivalent. All critical parameters including frequency, output type, supply voltage, function, and package dimensions are identical. No circuit modifications are required.

Q: What is the significance of the 0.18mm difference in maximum seated height?

A: The height difference (1.42mm vs. 1.60mm) is within standard PCB assembly tolerances and does not affect component placement, solder reflow profiles, or board-level clearances. This difference is not a limiting factor for substitution.

Q: Does the SXO75C3A071-125.000M meet the same compliance requirements as the original part?

A: Yes. The substitute part meets or exceeds compliance requirements. It carries ROHS3 Compliant certification (enhanced over RoHS Compliant) and shares identical ECCN and HTSUS classifications with the original part.

Q: Is the maximum supply current specification relevant to substitution?

A: The SXO75C3A071-125.000M specifies 65mA maximum supply current, while the original part does not provide this specification. This additional specification does not affect substitution eligibility. The specified current value ensures adequate power supply design margins.

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

A: ROHS3 Compliant represents compliance with the latest RoHS 3 directive, which includes additional restricted substances compared to earlier RoHS versions. The substitute part's ROHS3 status indicates enhanced environmental compliance and regulatory alignment.

Q: Are there any packaging differences between the two parts?

A: Both parts use identical 4-SMD, No Lead packaging in bulk form. No packaging conversion or handling procedure changes are required when transitioning from the 7WA2502008 to the SXO75C3A071-125.000M.
