Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC-13.513MBD-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 13.513 MHz (exact match required)
• Output Type: 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
• Package Dimensions: 3.20mm × 2.50mm
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: MSL 1

The substitute part 7X-13.513MBD-T meets all mandatory matching parameters. The primary technical difference is the base resonator technology (Crystal vs. MEMS) and maximum supply current specification, which do not affect functional compatibility in applications designed for the original part.

Engineering Selection Recommendations

The 7X-13.513MBD-T is the direct substitute for the obsolete TC-13.513MBD-T. Selection of this substitute is supported by the following engineering factors:

Product Status: The 7X-13.513MBD-T maintains Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete TC-13.513MBD-T.

Compliance & Certifications: The substitute part carries RoHS Compliance and REACH Unaffected certifications, meeting modern regulatory requirements for electronic components in regulated industries.

Electrical Equivalence: Both parts deliver identical electrical performance across frequency, output type, supply voltage, stability, and operating temperature specifications. The 10mA reduction in maximum supply current (15mA vs. 25mA) represents improved efficiency and does not impact compatibility with designs specified for the original part.

Mechanical Compatibility: Package type, footprint dimensions (3.20mm × 2.50mm), and mounting type are identical. The 0.30mm increase in seated height (1.10mm vs. 0.80mm) must be verified against PCB clearance requirements in height-constrained applications.

Resonator Technology: The shift from MEMS to Crystal-based resonator does not affect functional compatibility. Both technologies deliver the specified frequency stability and operating characteristics required for this application class.

Frequently Asked Questions (FAQ)

Q: Can the 7X-13.513MBD-T be used as a direct replacement for the TC-13.513MBD-T without circuit modifications?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. No circuit modifications are required. Verify PCB clearance for the 0.30mm height difference.

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

A: The base resonator technology differs, but both deliver identical frequency stability (±25ppm) and operating characteristics. This difference does not affect functional compatibility in applications designed for the TC-13.513MBD-T.

Q: Why is the maximum supply current lower in the substitute part?

A: The 7X-13.513MBD-T draws a maximum of 15mA compared to 25mA for the TC-13.513MBD-T. This represents improved power efficiency and does not impact compatibility. Designs specified for 25mA operation will function correctly with the lower current draw.

Q: Are there any compliance or regulatory differences between the two parts?

A: The 7X-13.513MBD-T carries explicit RoHS Compliance and REACH Unaffected certifications. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What is the impact of the 0.30mm height difference on PCB design?

A: The substitute part has a maximum seated height of 1.10mm compared to 0.80mm for the original. Verify that PCB clearance, component placement, and any height-constrained enclosure requirements accommodate this dimension. No redesign is typically required unless height constraints are critical.

Q: Is the 7X-13.513MBD-T available in the same packaging and quantity as the original?

A: Both parts use identical 4-SMD, No Lead packaging. Current inventory for the 7X-13.513MBD-T is 842 pieces. Verify availability with your supplier for production quantities.

Q: Can I use the 7X-13.513MBD-T in new designs, or is it only for replacement of obsolete parts?

A: The 7X-13.513MBD-T is an Active product suitable for both new designs and obsolescence replacement. Its Active status ensures long-term supply chain support.
