Parameter Comparison

Engineering Selection Recommendations

Primary Selection (7C-12.000MBE-T): The TXC CORPORATION 7C-12.000MBE-T is the original specification part. It carries RoHS Compliant status and MSL Level 1 rating, indicating unlimited shelf life under controlled storage conditions. This part is suitable for all applications requiring the specified electrical and mechanical parameters.

Substitute Selection (SXO53C3A481-12.000M): The Suntsu Electronics SXO53C3A481-12.000M is electrically and mechanically equivalent to the 7C-12.000MBE-T. The substitute part carries ROHS3 Compliant status, meeting current RoHS requirements. A notable difference is the maximum supply current specification: the substitute part specifies 16mA maximum compared to 30mA for the original part. This lower current specification indicates improved power efficiency and does not restrict compatibility in applications designed for the original 30mA specification.

Both parts share identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, dimensions, and mounting characteristics. Both are classified under ECCN EAR99 for export control purposes.

Selection between these parts should be based on availability, lead time, packaging requirements (Tape & Reel versus Bulk), and supply chain considerations. The substitute part is suitable for direct replacement in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the SXO53C3A481-12.000M directly replace the 7C-12.000MBE-T on a PCB?

A: Yes. Both parts are identical in package type (4-SMD, No Lead), dimensions (5.00mm x 3.20mm), and maximum height (1.40mm). The footprint and solder pad layout are compatible, enabling direct PCB substitution without layout modification.

Q: What is the significance of the different maximum supply current specifications (30mA vs. 16mA)?

A: The substitute part's lower maximum supply current specification (16mA) indicates improved power efficiency. This does not restrict compatibility. Circuits designed for the original 30mA specification will operate correctly with the substitute part, which will draw less current during operation.

Q: Are there differences in RoHS compliance between these parts?

A: Both parts are RoHS compliant. The original part carries RoHS Compliant status, while the substitute carries ROHS3 Compliant status. ROHS3 represents the current RoHS directive revision and is fully compatible with applications requiring RoHS compliance.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: The original part is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The substitute part is supplied in Bulk packaging. Tape & Reel packaging provides component protection and automated handling capability, while Bulk packaging is typically used for manual assembly or smaller quantity requirements. Packaging choice does not affect electrical or mechanical performance.

Q: Are the frequency stability specifications identical?

A: Yes. Both parts specify ±50ppm frequency stability across the operating temperature range of -40°C to 85°C. This ensures equivalent timing accuracy for applications requiring this oscillator frequency.

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

A: Yes. Both parts meet identical electrical and mechanical specifications for the 12 MHz CMOS oscillator category with enable/disable functionality. Either part is suitable for new designs requiring these specifications.

Q: What is MSL Level 1 rating?

A: MSL (Moisture Sensitivity Level) Level 1 indicates unlimited shelf life under controlled storage conditions (typically 30°C/85% RH). The original part carries this rating. Components with MSL Level 1 do not require special moisture control during storage or handling.
