Parameter Comparison

Engineering Selection Recommendations

The SXO22C3A171-20.000M from Suntsu Electronics, Inc. is a direct substitute for the 8W-20.000MBB-T. Both parts are Active status products with ROHS3 compliance and identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).

Electrical Compatibility: All critical electrical parameters match exactly, including frequency, output type, supply voltage, function, frequency stability, and operating temperature range. The SXO22C3A171-20.000M operates at a lower maximum supply current (10mA versus 15mA), which represents an operational advantage in power consumption.

Mechanical Compatibility: Package type, dimensions, and mounting type are identical. The seated height difference (0.039" versus 0.035") is within acceptable PCB assembly tolerances for surface mount components and does not affect board-level compatibility.

Regulatory Compliance: Both parts meet ROHS3 requirements and share identical export classification codes, ensuring compliance with applicable regulations.

Frequently Asked Questions (FAQ)

Q: Can the SXO22C3A171-20.000M replace the 8W-20.000MBB-T in existing designs?

A: Yes. The SXO22C3A171-20.000M is electrically and mechanically compatible with the 8W-20.000MBB-T. All critical parameters including frequency, output type, supply voltage, function, frequency stability, and operating temperature range are identical. Package dimensions and mounting type match exactly.

Q: What is the difference in supply current between these parts?

A: The 8W-20.000MBB-T has a maximum supply current of 15mA, while the SXO22C3A171-20.000M has a maximum supply current of 10mA. The lower current consumption of the substitute part does not affect compatibility and may provide power efficiency benefits.

Q: Are there differences in package height?

A: The seated height of the 8W-20.000MBB-T is 0.035" (0.90mm), while the SXO22C3A171-20.000M is 0.039" (1.00mm). This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not impact board-level compatibility or functionality.

Q: Do both parts have the same regulatory compliance?

A: Yes. Both the 8W-20.000MBB-T and SXO22C3A171-20.000M are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What packaging formats are available for these parts?

A: The 8W-20.000MBB-T is supplied in Tape & Reel (TR) packaging. The SXO22C3A171-20.000M is supplied in Bulk packaging. Packaging format selection depends on procurement volume and assembly process requirements.
