Engineering Selection Recommendations

7X-8.192MBD-T (TXC CORPORATION)

This substitute is manufactured by the same supplier as the main part and maintains identical electrical specifications across all critical parameters. The 7X series uses crystal-based resonator technology instead of MEMS, with Active product status ensuring long-term availability. Current consumption is reduced to 15mA maximum, providing improved power efficiency. The component carries RoHS Compliance and REACH Unaffected certifications. Height increase from 0.80mm to 1.10mm requires PCB assembly clearance verification. Operating temperature range remains -40°C ~ 85°C, matching the main part specification.

FK0810002 (Diodes Incorporated)

This substitute provides the lowest current consumption at 10mA maximum, with additional disable-state current specification of 10µA. The SaRonix-eCera™ FK series maintains identical electrical performance for frequency, stability, and output characteristics. ROHS3 Compliance and REACH Unaffected certifications are provided. Operating temperature range is narrower at -20°C ~ 70°C, which may limit applicability in systems requiring full -40°C ~ 85°C operation. Height is 1.15mm, requiring PCB assembly clearance verification. Active product status ensures supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the TC-8.192MBD-T be directly replaced with the 7X-8.192MBD-T?

A: Yes. Both parts share identical electrical specifications for frequency, output type, supply voltage, function, frequency stability, package, and dimensions. The primary difference is resonator technology (MEMS vs. Crystal) and reduced current consumption in the 7X series. PCB assembly height clearance must be verified due to the 0.30mm increase in seated height.

Q: What is the key difference between the 7X-8.192MBD-T and FK0810002?

A: Both are crystal-based oscillators with identical core electrical specifications. The FK0810002 offers lower current consumption (10mA vs. 15mA) and includes disable-state current specification (10µA). The FK0810002 has a narrower operating temperature range (-20°C ~ 70°C vs. -40°C ~ 85°C), which may restrict use in extended temperature applications.

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

A: The 7X-8.192MBD-T carries RoHS Compliance certification. The FK0810002 carries ROHS3 Compliance certification, representing a more recent regulatory standard. Both parts are REACH Unaffected. All three parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Does the increase in seated height affect PCB assembly?

A: The main part has a maximum seated height of 0.80mm. Both substitutes are taller: 7X-8.192MBD-T at 1.10mm and FK0810002 at 1.15mm. PCB layout and component placement must be reviewed to ensure adequate clearance above the oscillator. This is particularly critical in applications with height-constrained assemblies or stacked components.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For systems requiring the full -40°C ~ 85°C operating range, the 7X-8.192MBD-T is appropriate. For applications operating within -20°C ~ 70°C with power consumption optimization priority, the FK0810002 offers superior efficiency. Both parts have Active product status, ensuring long-term supply availability.

Q: Is the MEMS-based TC-8.192MBD-T fundamentally different from the crystal-based substitutes?

A: Yes. MEMS oscillators use microelectromechanical systems for frequency generation, while crystal oscillators use piezoelectric crystals. Both technologies achieve the specified ±25ppm frequency stability and identical electrical output characteristics. The substitutes use crystal technology, which is widely established in production environments.

Q: Can the FK0810002 be used in applications requiring -40°C operation?

A: No. The FK0810002 operating temperature range is -20°C ~ 70°C. Applications requiring operation at -40°C must use either the main part (TC-8.192MBD-T) or the 7X-8.192MBD-T substitute, both of which support -40°C ~ 85°C operation.
