Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TB-6.000MBD-T are qualified based on the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 6.0000 MHz
• Output Type: CMOS
• Function: Enable/Disable capability
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm
• Physical Dimensions: 5.00mm x 3.20mm (length x width)
• Mounting Type: Surface Mount

Voltage Compatibility:

• Primary supply voltage of 3.3V is required for direct substitution
• Parts supporting extended voltage ranges (1.8V ~ 3.3V) are compatible when operating at 3.3V

Package Considerations:

• Direct substitutes use 4-SMD, No Lead or 4-VDFN packages with equivalent footprints
• Height variations are acceptable within PCB assembly constraints

Two substitute parts meet these criteria: the 510CBA6M00000BAGR (Skyworks Solutions Inc., Crystal-based XO) and the DSC1001BI2-006.0000 (Microchip Technology, MEMS-based XO).

Parameter Comparison

Engineering Selection Recommendations

510CBA6M00000BAGR (Skyworks Solutions Inc.): This substitute is a direct functional equivalent with identical frequency, output type, supply voltage, and physical dimensions. The primary difference is the use of a Crystal-based resonator instead of MEMS technology. Both parts maintain ±25ppm frequency stability and Enable/Disable functionality. The 510CBA6M00000BAGR has an Active product status, ensuring long-term availability. Maximum supply current is 26mA, marginally higher than the original 25mA specification. Height is 1.28mm compared to 0.80mm for the original part; this difference must be evaluated against PCB assembly clearance requirements. Moisture sensitivity remains at MSL 1 (Unlimited).

DSC1001BI2-006.0000 (Microchip Technology): This substitute maintains MEMS resonator technology consistent with the original design. It supports an extended supply voltage range of 1.8V ~ 3.3V, providing greater flexibility in applications requiring lower voltage operation. The DSC1001BI2-006.0000 has an Active product status with AEC-Q100 automotive qualification. Maximum supply current is significantly lower at 6.3mA, offering power efficiency advantages. The package is 4-VDFN instead of 4-SMD, No Lead; footprint dimensions remain identical at 5.00mm x 3.20mm. Height is 0.90mm. Moisture sensitivity is MSL 3 (168 Hours), requiring controlled storage conditions. RoHS3 compliance and REACH Unaffected status are documented.

Both substitutes are suitable for applications requiring 6 MHz CMOS oscillators with Enable/Disable control. Selection between them depends on resonator technology preference, power consumption requirements, moisture handling capabilities, and package compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the 510CBA6M00000BAGR be used as a direct replacement for the TB-6.000MBD-T?

A: The 510CBA6M00000BAGR is functionally equivalent in frequency, output type, supply voltage, and Enable/Disable capability. The primary consideration is the height difference: 1.28mm versus 0.80mm. Verify that PCB assembly clearance accommodates the taller component. The Crystal-based resonator technology differs from the original MEMS design but maintains identical frequency stability (±25ppm).

Q: What are the key differences between the two substitute parts?

A: The 510CBA6M00000BAGR uses Crystal resonator technology with maximum supply current of 26mA and MSL 1 moisture sensitivity. The DSC1001BI2-006.0000 uses MEMS resonator technology with maximum supply current of 6.3mA, extended voltage range (1.8V ~ 3.3V), MSL 3 moisture sensitivity, and AEC-Q100 qualification. The DSC1001BI2-006.0000 offers lower power consumption and automotive-grade reliability.

Q: Is the package difference between 4-SMD, No Lead and 4-VDFN significant?

A: Both packages share identical footprint dimensions (5.00mm x 3.20mm). The 4-VDFN package used by the DSC1001BI2-006.0000 is a standard surface mount package compatible with automated assembly equipment. Verify that your PCB design accommodates the 4-VDFN land pattern; if the original design uses 4-SMD, No Lead pads, layout modification may be required.

Q: What is the impact of MSL 3 moisture sensitivity on the DSC1001BI2-006.0000?

A: MSL 3 (168 Hours) requires controlled storage conditions and limits the time the component can be exposed to ambient humidity before soldering. The original TB-6.000MBD-T has MSL 1 (Unlimited), allowing indefinite storage without moisture control. If your supply chain includes extended storage periods or high-humidity environments, the 510CBA6M00000BAGR with MSL 1 may be preferable.

Q: Are both substitutes compatible with the -40°C ~ 85°C operating temperature range?

A: Yes. Both the 510CBA6M00000BAGR and DSC1001BI2-006.0000 operate across the full -40°C ~ 85°C temperature range specified for the original TB-6.000MBD-T, with identical ±25ppm frequency stability maintained throughout this range.

Q: Which substitute offers better power efficiency?

A: The DSC1001BI2-006.0000 has maximum supply current of 6.3mA, significantly lower than the TB-6.000MBD-T (25mA) and 510CBA6M00000BAGR (26mA). For battery-powered or power-constrained applications, the DSC1001BI2-006.0000 is the preferred choice.

Q: Can the DSC1001BI2-006.0000 operate at voltages below 3.3V?

A: Yes. The DSC1001BI2-006.0000 supports supply voltages from 1.8V to 3.3V. When operating at 3.3V, it is fully compatible with the original TB-6.000MBD-T specification. Lower voltage operation (1.8V ~ 3.0V) is available if your application design permits.
