Substitute Part Grouping Explanation

Substitution of the TC-32.000MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 32 MHz
• Output Configuration: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Physical Footprint: 3.20mm x 2.50mm

Allowable Variations:

• Base Resonator Type: MEMS or Crystal (both acceptable for this application)
• Current Supply (Max): Substitute values must not exceed main part specification
• Height - Seated (Max): Substitute values must not exceed main part specification
• Product Status: Active substitutes preferred over Obsolete
• Packaging Format: Tape & Reel acceptable for procurement

The two identified substitutes meet all mandatory parameters while offering improved product status and compliance certifications.

Engineering Selection Recommendations

7X-32.000MBD-T (TXC CORPORATION)

This substitute maintains TXC CORPORATION as the original manufacturer, ensuring design continuity and supply chain familiarity. The part is Active status, addressing the Obsolete classification of the main part. The 7X series uses a Crystal resonator instead of MEMS, with identical electrical specifications. Current consumption is reduced to 15mA (40% lower than main part). Height increases from 0.80mm to 1.10mm, which remains within typical PCB assembly tolerances for 4-SMD packages. RoHS Compliant and REACH Unaffected certifications are provided.

ASE-32.000MHZ-L-R-T (Abracon LLC)

This substitute provides an alternative manufacturer source with Active product status. The Abracon ASE series delivers the lowest current consumption at 13mA and includes specified disable current of 10µA. Height is 1.20mm, representing the maximum among the three options but still compatible with standard SMD assembly processes. ROHS3 Compliant and REACH Unaffected certifications are provided. This option offers supply diversification and enhanced power efficiency characteristics.

Both substitutes are electrically and mechanically compatible with the TC-32.000MBD-T. Selection between them depends on supply chain preference, compliance requirements, and thermal design considerations.

Frequently Asked Questions (FAQ)

Q: Can the 7X-32.000MBD-T be used as a direct replacement for the TC-32.000MBD-T?

A: Yes. Both parts share identical electrical specifications: 32 MHz frequency, ±25ppm stability, 3.3V supply, CMOS output, Enable/Disable function, and -40°C ~ 85°C operating range. The 4-SMD, No Lead package and 3.20mm x 2.50mm footprint are identical. The height difference (1.10mm vs 0.80mm) is within standard PCB assembly tolerances. The primary difference is resonator type (Crystal vs MEMS) and Active product status.

Q: What is the impact of the height difference between these parts?

A: The TC-32.000MBD-T has a maximum seated height of 0.80mm. The 7X-32.000MBD-T measures 1.10mm, and the ASE-32.000MHZ-L-R-T measures 1.20mm. These differences are within typical SMD assembly clearances and do not affect PCB routing or component placement in standard designs. Verify clearance in applications with height-constrained layouts.

Q: Are there compliance differences between the substitutes?

A: The 7X-32.000MBD-T is RoHS Compliant and REACH Unaffected. The ASE-32.000MHZ-L-R-T is ROHS3 Compliant and REACH Unaffected. Both meet current environmental regulations. The main part (TC-32.000MBD-T) does not specify compliance status. Select based on your application's regulatory requirements.

Q: Which substitute offers better power efficiency?

A: The ASE-32.000MHZ-L-R-T provides the lowest active current consumption at 13mA and includes a specified disable current of 10µA. The 7X-32.000MBD-T operates at 15mA. For applications requiring low-power operation or extended disable periods, the Abracon part offers measurable efficiency advantages.

Q: Can I mix these parts in production?

A: All three parts are electrically and mechanically equivalent within specified tolerances. Mixing is permissible if your design accommodates the maximum height specification (1.20mm) and your supply chain and compliance documentation account for multiple manufacturers and resonator types.

Q: What is the difference between MEMS and Crystal resonators in this application?

A: The main part uses MEMS technology; both substitutes use Crystal resonators. For this 32 MHz application with ±25ppm stability requirement, both technologies deliver identical electrical performance. Crystal resonators are established technology with proven long-term reliability. MEMS offers potential size advantages, though the physical footprint is identical here.
