• Operating Temperature: -10°C ~ 70°C (thermal operating range)

Mechanical Equivalence Requirements:

• Package Type: 4-SMD, No Lead (PCB footprint compatibility)
• Physical Dimensions: 5.00mm x 3.20mm (board layout fit)
• Seated Height: 1.40mm maximum (clearance compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)

Compliance Requirements:

• RoHS Status: Compliant (regulatory requirement)
• Base Resonator: Crystal (oscillator technology type)
• Oscillator Type: XO (Standard) (performance class)

The substitute part SXO53C3C171-20.000M meets all electrical, mechanical, and compliance criteria for direct substitution in applications utilizing the 7C-20.000MBA-T.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (7C-20.000MBA-T): The 7C-20.000MBA-T remains the primary component choice when TXC CORPORATION supply is available and design specifications allow for maximum supply current of 30mA. This part is RoHS Compliant and carries active product status with established supply chain presence.

Substitute Part Selection (SXO53C3C171-20.000M): The SXO53C3C171-20.000M from Suntsu Electronics, Inc. is a direct electrical and mechanical equivalent suitable for applications where the lower maximum supply current of 16mA is acceptable. This substitute part is ROHS3 Compliant and maintains active product status. The substitute part is appropriate for designs with reduced power consumption requirements or when TXC CORPORATION supply is constrained.

Compliance Considerations: Both parts satisfy EAR99 export classification and HTSUS code 8542.39.0001. The substitute part carries ROHS3 compliance, which exceeds the RoHS Compliant status of the primary part, ensuring regulatory compatibility in all applications requiring RoHS certification.

Supply Chain Flexibility: Selection between these parts should be based on availability, lead time, and supply chain requirements. Both parts maintain active production status and are suitable for new designs and production applications.

Frequently Asked Questions (FAQ)

Q: Can the SXO53C3C171-20.000M be used as a direct replacement for the 7C-20.000MBA-T?

A: Yes. The SXO53C3C171-20.000M meets all electrical and mechanical specifications required for direct substitution. Both parts operate at 20 MHz with 3.3V CMOS output, enable/disable functionality, ±25ppm frequency stability, and identical package dimensions (5.00mm x 3.20mm x 1.40mm). The substitute part has a lower maximum supply current (16mA versus 30mA), which is acceptable for applications not requiring the full 30mA specification.

Q: Are there any PCB layout changes required when switching between these parts?

A: No. Both the 7C-20.000MBA-T and SXO53C3C171-20.000M use identical 4-SMD, No Lead packages with matching physical dimensions of 5.00mm x 3.20mm and seated height of 1.40mm. PCB footprints, land patterns, and assembly processes remain unchanged.

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

A: The 7C-20.000MBA-T has a maximum supply current of 30mA, while the SXO53C3C171-20.000M has a maximum supply current of 16mA. The substitute part draws less current, which may provide power consumption benefits in battery-powered or power-constrained applications. Designs must verify that the lower current specification meets application requirements.

Q: Are both parts RoHS compliant?

A: Yes. The 7C-20.000MBA-T is RoHS Compliant, and the SXO53C3C171-20.000M is ROHS3 Compliant. Both parts satisfy RoHS requirements for new designs and production applications.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -10°C to 70°C. No thermal performance differences exist between the primary part and substitute part.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application does not require the full 30mA maximum supply current specification of the primary part. The substitute part is mechanically and electrically compatible with all designs using the 7C-20.000MBA-T, with the only consideration being the reduced maximum supply current rating.

Q: What is the frequency stability specification for both parts?

A: Both the 7C-20.000MBA-T and SXO53C3C171-20.000M maintain ±25ppm frequency stability across the operating temperature range. Timing accuracy is identical between both parts.

Q: Are there any packaging differences between these parts?

A: The 7C-20.000MBA-T is supplied in Tape & Reel (TR) packaging, while the SXO53C3C171-20.000M is supplied in Bulk packaging. Both use identical 4-SMD, No Lead component packages. Packaging format differences affect supply chain handling and inventory management but do not impact electrical or mechanical performance.
