Engineering Selection Recommendations

Substitution Feasibility:

The 7X-32.350MBD-T is a direct functional substitute for the TC-32.350MBD-T based on electrical parameter equivalence. Both components share identical frequency, output type, supply voltage, function, frequency stability, and operating temperature range.

Product Status Consideration:

The TC-32.350MBD-T is classified as Obsolete, while the 7X-32.350MBD-T is Active. The substitute part is currently manufactured and available in inventory (1072 Pcs New Original In Stock), ensuring supply chain continuity.

Compliance and Certification:

The 7X-32.350MBD-T carries RoHS Compliance and REACH Unaffected certifications. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Physical Dimension Consideration:

The substitute part exhibits a maximum seated height of 0.043" (1.10mm), which exceeds the main part specification of 0.031" (0.80mm). This dimensional difference must be evaluated against PCB layout constraints and available clearance in the target application.

Current Consumption:

The substitute part operates at a maximum supply current of 15mA, which is lower than the main part specification of 25mA. This represents an improvement in power efficiency and does not present a compatibility issue.

Frequently Asked Questions (FAQ)

Q: Can the 7X-32.350MBD-T directly replace the TC-32.350MBD-T in existing designs?

A: Electrical substitution is valid based on frequency, output type, supply voltage, function, and frequency stability equivalence. Physical substitution requires verification of PCB clearance due to the increased seated height of the substitute part (0.043" vs. 0.031").

Q: What is the primary difference between the TC and 7X series oscillators?

A: The TC-32.350MBD-T uses a MEMS resonator, while the 7X-32.350MBD-T uses a Crystal resonator. Both deliver identical electrical performance at the specified frequency and operating conditions.

Q: Is the 7X-32.350MBD-T suitable for new production designs?

A: Yes. The 7X-32.350MBD-T is classified as Active and carries RoHS Compliance certification, making it suitable for new production applications. Current inventory is 1072 Pcs New Original In Stock.

Q: Does the lower current consumption of the 7X-32.350MBD-T affect circuit design?

A: No. The substitute part operates at 15mA maximum, which is lower than the main part specification of 25mA. This does not create compatibility issues and may reduce overall system power consumption.

Q: What must be verified before implementing the 7X-32.350MBD-T as a substitute?

A: PCB layout clearance must be verified to accommodate the increased seated height of 0.043" (1.10mm). All other electrical and mechanical parameters are equivalent or superior to the main part specification.

Q: Are both parts manufactured by the same company?

A: Yes. Both the TC-32.350MBD-T and 7X-32.350MBD-T are manufactured by TXC CORPORATION.
