Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TD-10.000MBD-T is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 10 MHz
• Output Type: CMOS
• Function: Enable/Disable
• Operating Temperature Range: -40°C ~ 85°C
• Frequency Stability: ±25ppm
• Package / Case: 4-SMD, No Lead
• Physical Dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm)
• Mounting Type: Surface Mount

Allowable Variation Parameters:

• Supply Voltage: 3.3V nominal (acceptable range: 2.25V ~ 3.6V for compatible designs)
• Current - Supply (Max): Variation acceptable if within circuit design limits
• Base Resonator Type: MEMS or Crystal technology both acceptable
• Height - Seated (Max): Minor variations acceptable within PCB assembly constraints
• Product Status: Active status preferred for long-term availability

Substitutes are classified as Direct (full electrical and mechanical compatibility) or Similar (compatible with minor parameter variations requiring design verification).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Preferred for Replacement):

8W-10.000MBD-T is the primary direct substitute. Manufactured by TXC CORPORATION, this part maintains identical electrical specifications and physical dimensions to the TD-10.000MBD-T. The 8W series is Active status, ensuring long-term availability. Current consumption is reduced to 10mA maximum, providing improved power efficiency. Height variation (0.035" vs. 0.031") is within standard PCB assembly tolerances. ROHS3 compliance provides regulatory advantage for new designs.

SXO22C3C481-10.000M is a secondary direct substitute from Suntsu Electronics, Inc. This crystal-based oscillator matches all critical electrical parameters and physical dimensions. Current consumption is further reduced to 7mA maximum, offering superior power efficiency. Active product status ensures supply continuity. Height is 0.039", requiring verification against PCB clearance specifications. ROHS3 compliance is confirmed.

Similar Substitute (Conditional Compatibility):

ASDMPC-10.000MHZ-LR-T from Abracon LLC is classified as a similar substitute due to extended supply voltage range (2.25V ~ 3.6V) and higher maximum current consumption (35mA). This MEMS-based oscillator maintains identical frequency, output type, function, and frequency stability. Physical dimensions and package are identical. Height is 0.035", matching the 8W series. Current - Supply (Disable) specification (95µA) is provided, offering additional design data. ROHS3 and REACH compliance are confirmed. Selection requires verification that the 3.3V nominal supply voltage operates within the acceptable 2.25V ~ 3.6V range for the application circuit.

Frequently Asked Questions (FAQ)

Q: Why is the TD-10.000MBD-T classified as Obsolete?

A: The TD-10.000MBD-T is no longer in active production. Direct substitutes from TXC CORPORATION (8W series) and alternative manufacturers (Suntsu, Abracon) provide equivalent functionality with Active product status, ensuring ongoing availability and support.

Q: Can the 8W-10.000MBD-T be used as a direct replacement without circuit modification?

A: Yes. The 8W-10.000MBD-T is a direct substitute with identical electrical specifications, frequency, output type, supply voltage, and package dimensions. The reduced current consumption (10mA vs. 25mA) is beneficial and requires no circuit changes. Height variation (0.035" vs. 0.031") is within standard PCB assembly tolerances.

Q: What is the difference between MEMS and Crystal-based oscillators in these substitutes?

A: The TD-10.000MBD-T and ASDMPC-10.000MHZ-LR-T use MEMS resonators, while the 8W-10.000MBD-T and SXO22C3C481-10.000M use crystal resonators. Both technologies deliver identical frequency stability (±25ppm) and operating characteristics for this application. Crystal-based oscillators typically offer lower current consumption.

Q: Are there any height clearance concerns when substituting these parts?

A: The TD-10.000MBD-T has a maximum seated height of 0.031" (0.80mm). Direct substitutes have heights of 0.035" (0.90mm) or 0.039" (1.00mm). Verify PCB assembly clearance specifications to confirm compatibility. Height differences are typically within standard PCB design tolerances.

Q: Is the ASDMPC-10.000MHZ-LR-T suitable for 3.3V applications?

A: Yes. The ASDMPC-10.000MHZ-LR-T operates across 2.25V ~ 3.6V, which includes the 3.3V nominal supply voltage of the TD-10.000MBD-T. Verify that the application circuit supply voltage remains within this range under all operating conditions.

Q: What is the significance of RoHS3 compliance for these substitutes?

A: ROHS3 compliance indicates conformance to Restriction of Hazardous Substances regulations. The 8W-10.000MBD-T, SXO22C3C481-10.000M, and ASDMPC-10.000MHZ-LR-T are all ROHS3 compliant, meeting environmental and regulatory requirements for new designs and production.

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

A: Direct substitutes (8W-10.000MBD-T and SXO22C3C481-10.000M) are fully interchangeable without design modification. The similar substitute (ASDMPC-10.000MHZ-LR-T) requires verification of supply voltage range compatibility and current consumption limits within the application circuit.

Q: What packaging options are available for these substitutes?

A: The 8W-10.000MBD-T and SXO22C3C481-10.000M are available in standard surface mount packaging. The SXO22C3C481-10.000M is specified as Bulk packaging. The ASDMPC-10.000MHZ-LR-T is available in Tape & Reel (TR) format. Confirm packaging requirements for production and assembly processes.
