CCR30.0MXC7T Ceramic Resonator Equivalent & Substitute Parts

Part Overview

The CCR30.0MXC7T is a 30 MHz ceramic resonator manufactured by TDK Corporation with built-in 8 pF capacitor, designed for surface mount applications. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. The part operates across -40°C to 85°C with ±0.2% frequency stability and 40 Ohms impedance in a compact 3-SMD non-standard package measuring 2.50mm × 2.00mm.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for ceramic resonators is determined by matching the following critical parameters: operating frequency, frequency stability specification, built-in capacitance value, impedance rating, package form factor, and physical dimensions. The AWSCR-30.00CW-T from Abracon LLC meets the primary functional requirements of 30 MHz operation with ±0.2% frequency stability and identical package dimensions (2.50mm × 2.00mm). However, this substitute introduces variations in secondary parameters: capacitance is reduced to 5 pF, impedance increases to 50 Ohms, and the operating temperature range is narrowed to -25°C to 85°C. These differences must be evaluated against specific circuit requirements before implementation.

Parameter Comparison

Engineering Selection Recommendations

The AWSCR-30.00CW-T represents the primary equivalent substitute for the obsolete CCR30.0MXC7T. Both components share identical 30 MHz frequency specification, ±0.2% stability, and compatible 3-SMD package footprint. The Abracon part carries active product status with ROHS3 compliance and REACH affected designation, supporting long-term supply chain availability.

Selection of the AWSCR-30.00CW-T requires circuit-level validation of three parameter deviations: the 3 pF capacitance reduction (8 pF to 5 pF), 10 Ohm impedance increase (40 Ohms to 50 Ohms), and 15°C lower temperature floor (-40°C to -25°C). Applications operating exclusively within -25°C to 85°C temperature bounds and tolerating the specified impedance and capacitance variations are suitable for direct substitution. Applications requiring the full -40°C to 85°C range or dependent on the original 8 pF capacitance value require additional circuit analysis or alternative sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can the AWSCR-30.00CW-T directly replace the CCR30.0MXC7T in all applications?

A: Direct replacement is possible only when circuit design tolerates the parameter differences: 5 pF built-in capacitance instead of 8 pF, 50 Ohms impedance instead of 40 Ohms, and operating temperature range limited to -25°C to 85°C. Applications with strict temperature or impedance requirements require circuit validation.

Q: What is the impact of the capacitance difference between 8 pF and 5 pF?

A: The 3 pF reduction affects resonator load capacitance and frequency response characteristics. Circuit designers must verify that the 5 pF value maintains acceptable frequency accuracy and stability within the application's oscillator circuit topology.

Q: Are the physical packages identical between these parts?

A: Both components use 3-SMD non-standard packages with identical footprint dimensions of 2.50mm × 2.00mm. Height differs slightly: CCR30.0MXC7T is 1.09mm while AWSCR-30.00CW-T is 1.19mm. This 0.10mm difference is typically accommodated in standard PCB assembly processes.

Q: What compliance certifications differ between the two parts?

A: The CCR30.0MXC7T carries REACH Unaffected status, while the AWSCR-30.00CW-T is REACH Affected and ROHS3 Compliant. Applications subject to REACH or RoHS regulations should verify the AWSCR-30.00CW-T compliance status against specific requirements.

Q: Why is the operating temperature range narrower for the substitute part?

A: The AWSCR-30.00CW-T operates from -25°C to 85°C compared to the original -40°C to 85°C. Applications requiring operation below -25°C cannot use this substitute without additional thermal management or alternative component selection.
