TC-25.000MCD-T MEMS Oscillator Equivalent & Substitute Parts

Part Overview

The TC-25.000MCD-T is a 25 MHz MEMS-based XO (Standard) oscillator manufactured by TXC CORPORATION. This component operates at 2.5V supply voltage with Enable/Disable functionality and CMOS output configuration. The device is housed in a 4-SMD, No Lead package measuring 3.20mm × 2.50mm with a maximum seated height of 0.80mm.

The TC-25.000MCD-T is classified as Obsolete. Equivalent substitute parts are necessary for ongoing production, maintenance, and design continuity where original components are no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC-25.000MCD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 25 MHz
• Output Configuration: CMOS
• Supply Voltage: 2.5V
• Function: Enable/Disable capability
• Frequency Stability: ±25ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead
• Physical Footprint: 3.20mm × 2.50mm

The OXJTDLJANF-25.000000 manufactured by Taitien meets all mandatory matching parameters. The primary distinction is the base resonator technology: the original part uses MEMS resonator technology, while the substitute uses Crystal resonator technology. Both technologies deliver identical electrical performance within the specified parameters and are functionally interchangeable at the circuit level.

Parameter Comparison

*The substitute part has a maximum seated height of 1.10mm compared to 0.80mm for the original. PCB layout clearance must be verified for applications with height constraints.

Engineering Selection Recommendations

The OXJTDLJANF-25.000000 is a direct functional equivalent for the obsolete TC-25.000MCD-T based on electrical parameter equivalence. Selection of this substitute is supported by the following factors:

Product Status: The substitute part is classified as Active, ensuring ongoing availability and supply chain continuity.

Compliance Certifications: The OXJTDLJANF-25.000000 carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components in regulated markets.

Electrical Equivalence: All critical electrical parameters—frequency, output type, supply voltage, function, stability, and operating temperature range—are identical between the original and substitute parts.

Physical Compatibility: Both parts share identical footprint dimensions (3.20mm × 2.50mm) and package type (4-SMD, No Lead), enabling direct PCB layout compatibility. The height difference (1.10mm vs. 0.80mm) requires verification only in applications with strict vertical clearance constraints.

Resonator Technology Difference: The substitute uses Crystal resonator technology instead of MEMS. Both technologies deliver equivalent performance within the specified ±25ppm frequency stability and operating temperature range. This difference does not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the OXJTDLJANF-25.000000 be used as a direct replacement for the TC-25.000MCD-T without circuit modifications?

A: Yes. The substitute part is electrically equivalent across all specified parameters: frequency, output type, supply voltage, function, stability, and operating temperature range. No circuit modifications are required. PCB layout compatibility is maintained due to identical footprint and package type.

Q: What is the significance of the resonator technology difference (MEMS vs. Crystal)?

A: Both MEMS and Crystal resonator technologies deliver identical electrical performance within the specified parameters for this application. The frequency stability (±25ppm), operating temperature range (-40°C ~ 85°C), and all other electrical characteristics are equivalent. The technology difference does not affect functional compatibility.

Q: Are there any height clearance concerns when substituting the OXJTDLJANF-25.000000?

A: The substitute part has a maximum seated height of 1.10mm compared to 0.80mm for the original. This 0.30mm difference must be verified against PCB layout clearance requirements. In most standard applications, this difference is not problematic. Applications with strict vertical space constraints require clearance verification.

Q: Is the OXJTDLJANF-25.000000 compliant with current regulatory standards?

A: Yes. The substitute part is ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic components in regulated markets.

Q: What is the packaging difference between the original and substitute parts?

A: The original TC-25.000MCD-T is supplied in standard packaging. The OXJTDLJANF-25.000000 is supplied in Tape & Reel (TR) format. Both parts use identical 4-SMD, No Lead package type and footprint. Tape & Reel packaging is standard for high-volume production and does not affect component performance or compatibility.

Q: Are both parts available in current inventory?

A: The TC-25.000MCD-T (Obsolete status) has 703 pieces in stock. The OXJTDLJANF-25.000000 (Active status) has 978 pieces in stock. The substitute part's Active status ensures continued availability for future production requirements.
