Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TD-24.000MBD-T are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

Mandatory Matching Parameters:

• Frequency: 24 MHz
• Output Type: CMOS
• Supply Voltage: 3.3V
• Function: Enable/Disable
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 4-SMD, No Lead
• Mounting Type: Surface Mount
• Size / Dimension: 0.098" L x 0.079" W (2.50mm x 2.00mm)

All identified substitute parts meet these mandatory parameters. Variations in current consumption and height-seated dimensions remain within acceptable tolerances for PCB layout and thermal management considerations.

Parameter Comparison

Engineering Selection Recommendations

8W-24.000MBD-T (TXC CORPORATION): This substitute maintains the same manufacturer lineage as the main part. It is classified as Active product status, ensuring long-term availability and supply chain continuity. The part is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. Current consumption is reduced to 15mA compared to the main part's 25mA, providing improved power efficiency. Height-seated dimension increases to 0.035" (0.90mm), which remains compatible with standard PCB assembly processes. This part is suitable for direct replacement in applications where the MEMS-to-Crystal resonator transition is acceptable.

SXO22C3C481-24.000M (Suntsu Electronics, Inc.): This substitute offers the lowest current consumption at 10mA, providing optimal power efficiency for battery-powered or power-constrained applications. The part is Active status with ROHS3 Compliance and REACH Unaffected certification. Height-seated dimension is 0.039" (1.00mm), representing the maximum height among the three options. This part is suitable for applications where power consumption optimization is a primary design consideration and PCB clearance permits the increased height.

Both substitute parts maintain identical electrical performance specifications (frequency, stability, output type, voltage, function, and temperature range) and mechanical compatibility (package, mounting type, footprint dimensions) with the obsolete TD-24.000MBD-T.

Frequently Asked Questions (FAQ)

Q: Can the 8W-24.000MBD-T directly replace the TD-24.000MBD-T without PCB modifications?

A: Yes. Both parts share identical footprint dimensions (0.098" L x 0.079" W / 2.50mm x 2.00mm), package type (4-SMD, No Lead), and mounting type (Surface Mount). The height difference (0.035" vs 0.031") is within standard PCB assembly tolerances and does not require layout changes.

Q: What is the primary difference between the TD-24.000MBD-T and its substitutes?

A: The main part uses a MEMS-based resonator, while both substitutes use crystal-based resonators. All three maintain identical frequency stability (±25ppm) and electrical performance. The substitutes offer reduced current consumption and Active product status.

Q: Which substitute should be selected for power-sensitive applications?

A: The SXO22C3C481-24.000M provides the lowest maximum supply current at 10mA, compared to 15mA for the 8W-24.000MBD-T and 25mA for the main part. Selection should be based on PCB clearance availability, as this part has the maximum height-seated dimension of 0.039" (1.00mm).

Q: Are both substitutes compliant with current environmental regulations?

A: Yes. Both the 8W-24.000MBD-T and SXO22C3C481-24.000M are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

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

A: Yes, provided that PCB layout accommodates the maximum height-seated dimension of the selected substitute (0.039" for SXO22C3C481-24.000M or 0.035" for 8W-24.000MBD-T). All electrical and mechanical parameters are compatible with the original TD-24.000MBD-T specification.

Q: What is the inventory status of these substitutes?

A: 8W-24.000MBD-T: 968 Pcs New Original In Stock. SXO22C3C481-24.000M: 17062 Pcs New Original In Stock. Both parts are readily available for immediate procurement.
