Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7WA2570002 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

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

The substitute part SXO75C3A071-125.000M from Suntsu Electronics, Inc. meets all mandatory matching parameters and is therefore classified as a direct equivalent for the 7WA2570002.

Parameter Comparison

Engineering Selection Recommendations

The SXO75C3A071-125.000M from Suntsu Electronics, Inc. is a direct substitute for the obsolete 7WA2570002 from TXC CORPORATION based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status, ensuring ongoing availability and manufacturer support. The original 7WA2570002 is obsolete, making the SXO75C3A071-125.000M the appropriate replacement for continued supply chain operations.

Compliance and Certifications: Both parts maintain RoHS compliance. The substitute part carries ROHS3 Compliant certification, meeting current regulatory requirements. Both parts are classified under ECCN EAR99 and HTSUS 8542.39.0001, confirming equivalent trade classification.

Physical and Electrical Compatibility: All critical electrical parameters match exactly: 125 MHz frequency, CMOS output, 3.3V supply voltage, Enable/Disable function, and ±50ppm frequency stability. The physical footprint is identical at 7.00mm x 5.00mm. The maximum seated height difference (1.42mm vs. 1.60mm) is within acceptable PCB assembly tolerances for surface mount components.

Supply Chain Availability: The substitute part has 3315 pieces in new original stock, compared to 691 pieces for the obsolete part, providing superior long-term availability for production requirements.

Frequently Asked Questions (FAQ)

Q: Can the SXO75C3A071-125.000M directly replace the 7WA2570002 without PCB modifications?

A: Yes. Both parts share identical electrical specifications (125 MHz, CMOS output, 3.3V, Enable/Disable function, ±50ppm stability) and identical physical footprints (7.00mm x 5.00mm, 4-SMD No Lead package). No PCB layout changes are required.

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

A: The SXO75C3A071-125.000M has a maximum seated height of 1.60mm compared to 1.42mm for the 7WA2570002. This 0.18mm difference is within standard PCB assembly tolerances and does not affect component placement, solder reflow profiles, or board clearance in typical applications.

Q: Why is the 7WA2570002 listed as obsolete?

A: The 7WA2570002 has reached end-of-life status with TXC CORPORATION. The SXO75C3A071-125.000M from Suntsu Electronics maintains active product status and identical specifications, making it the recommended replacement for new designs and ongoing production.

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

A: Both parts are RoHS compliant. The substitute part carries ROHS3 Compliant certification, which represents the current regulatory standard. Both parts are REACH Unaffected and classified under identical trade codes (ECCN EAR99, HTSUS 8542.39.0001).

Q: What is the current consumption specification for the substitute part?

A: The SXO75C3A071-125.000M specifies a maximum supply current of 65mA. The original 7WA2570002 does not provide this specification in the available documentation.

Q: Is the packaging format identical between the two parts?

A: Both parts use 4-SMD, No Lead surface mount packaging with identical physical dimensions (7.00mm x 5.00mm). The substitute part is supplied in Bulk packaging, while the original part packaging format is not specified.
