Electrical Equivalence Criteria:

• Frequency: 20.0000 MHz (exact match required)
• Output: CMOS (logic family compatibility)
• Supply Voltage: 3.3V (operating voltage compatibility)
• Frequency Stability: ±25ppm (timing accuracy specification)
• Operating Temperature: -10°C to 70°C (thermal operating range)
• Function: Enable/Disable (control functionality)

Mechanical Equivalence Criteria:

• Package: 4-SMD, No Lead (PCB footprint compatibility)
• Mounting: Surface Mount (assembly process compatibility)
• Dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm) (board layout compatibility)

Compliance Criteria:

• RoHS3 Compliant (regulatory requirement)
• ECCN: EAR99 (export classification)
• HTSUS: 8542.39.0001 (tariff classification)

The substitute part SXO22C3C171-20.000M meets all electrical, mechanical, and compliance criteria for direct substitution.

Engineering Selection Recommendations

Primary Substitute: SXO22C3C171-20.000M

The SXO22C3C171-20.000M from Suntsu Electronics, Inc. is a direct electrical and mechanical equivalent to the 8W-20.000MBA-T. Both devices are Active status products with ROHS3 compliance and identical frequency, output type, supply voltage, and frequency stability specifications.

Compatibility Assessment:

The substitute part maintains full compatibility across all critical electrical parameters. The maximum supply current of the substitute (10mA) is lower than the main part (15mA), which is advantageous for power consumption. The seated height difference (0.039" versus 0.035") is within typical PCB assembly tolerances for surface mount components and does not affect footprint compatibility.

Both parts share identical package dimensions (2.50mm x 2.00mm) and 4-SMD, No Lead configuration, ensuring direct PCB layout compatibility without redesign requirements.

Compliance Verification:

Both the main part and substitute are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, confirming regulatory and export equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SXO22C3C171-20.000M replace the 8W-20.000MBA-T in existing designs?

A: Yes. The substitute part meets all electrical and mechanical specifications. Identical frequency (20 MHz), output type (CMOS), supply voltage (3.3V), frequency stability (±25ppm), operating temperature range (-10°C to 70°C), and package configuration (4-SMD, No Lead, 2.50mm x 2.00mm) ensure direct compatibility without circuit modification.

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

A: The 8W-20.000MBA-T specifies a maximum supply current of 15mA, while the SXO22C3C171-20.000M specifies 10mA. The lower current consumption of the substitute is compatible with designs rated for the higher specification.

Q: Are there packaging differences between these oscillators?

A: The main part is supplied in Tape & Reel (TR) packaging, while the substitute is supplied in Bulk packaging. Both use identical 4-SMD, No Lead surface mount packages with the same footprint dimensions (2.50mm x 2.00mm). Packaging format does not affect component performance or PCB assembly compatibility.

Q: Is the height difference between these parts significant?

A: The seated height difference (0.035" for the main part versus 0.039" for the substitute) is 0.004 inches (0.10mm). This variation is within standard PCB assembly tolerances for surface mount components and does not affect board-level clearance or functionality in typical applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 8W-20.000MBA-T and SXO22C3C171-20.000M are ROHS3 compliant with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, confirming equivalent regulatory and export status.

Q: What is the moisture sensitivity level for these oscillators?

A: The 8W-20.000MBA-T specifies MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. This specification is not provided for the substitute part in the available data.
