SC30R12KT Equivalent & Substitute Parts

Part Overview

The SC30R12KT is a 120 nH shielded inductor manufactured by TE Connectivity Passive Product, designed for through-hole axial mounting applications. This component operates at 1.4 A maximum current with 90 mOhm DC resistance and is rated for temperatures from -55°C to 100°C. The part is actively produced and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent inductance values, tolerance specifications, and mounting configurations are required for design flexibility, inventory management, or supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the SC30R12KT are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Inductance value: 120 nH
• Inductance tolerance: ±10%
• Mounting type: Through hole axial configuration
• Frequency test point: 25 MHz
• RoHS compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Current rating: Minimum 1.1 A (substitute may have lower rating if application permits)
• DC resistance: Maximum 90 mOhm (substitute may have lower DCR)
• Operating temperature range: Minimum -55°C to 100°C coverage
• Self-resonant frequency: Minimum 640 MHz

The substitute part 9230-96-RC from Bourns Inc. matches the primary criteria with identical inductance, tolerance, mounting type, and frequency test specifications. Differences in shielding configuration, current rating, and physical dimensions are noted for application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

Both the SC30R12KT and 9230-96-RC are active products with ROHS3 compliance and identical inductance specifications at the 25 MHz test frequency. Selection between these parts depends on application-specific requirements:

SC30R12KT Selection Criteria:

• Applications requiring shielded inductor configuration to minimize electromagnetic interference
• Circuits requiring 1.4 A current capacity
• Designs with thermal requirements up to 100°C maximum operating temperature
• Applications where the larger physical footprint (4.20mm x 10.00mm) is acceptable

9230-96-RC Selection Criteria:

• Applications where unshielded inductor configuration is acceptable
• Circuits with maximum current requirements of 1.1 A
• Designs benefiting from lower DC resistance (80 mOhm vs. 90 mOhm)
• Designs with thermal requirements up to 105°C maximum operating temperature
• Space-constrained applications where the smaller physical footprint (2.41mm x 6.35mm) provides advantage
• Applications where phenolic core material is compatible with design requirements

Both parts maintain identical Q factor (40 @ 25 MHz) and self-resonant frequency characteristics within specified tolerances.

Frequently Asked Questions (FAQ)

Q: Can the 9230-96-RC directly replace the SC30R12KT in all applications?

A: Direct substitution is possible only when the application does not require shielded inductor characteristics and the maximum current requirement does not exceed 1.1 A. The unshielded configuration of the 9230-96-RC may introduce electromagnetic coupling in sensitive circuits where the SC30R12KT shielding is necessary.

Q: What is the impact of the different current ratings (1.4 A vs. 1.1 A)?

A: The SC30R12KT supports 1.4 A maximum current, while the 9230-96-RC supports 1.1 A maximum current. If the circuit design requires current levels between 1.1 A and 1.4 A, the SC30R12KT must be used. For circuits operating below 1.1 A, both parts are suitable.

Q: How do the physical dimensions affect PCB layout?

A: The SC30R12KT measures 0.165" diameter by 0.394" length (4.20mm x 10.00mm), while the 9230-96-RC measures 0.095" diameter by 0.250" length (2.41mm x 6.35mm). The 9230-96-RC is significantly smaller and may be preferred in space-constrained designs. However, PCB footprint compatibility must be verified before substitution.

Q: Are both parts suitable for high-temperature applications?

A: The SC30R12KT operates from -55°C to 100°C, while the 9230-96-RC operates from -55°C to 105°C. For applications requiring operation above 100°C, the 9230-96-RC provides 5°C additional thermal margin. For applications below 100°C, both parts are suitable.

Q: What is the significance of the shielding difference?

A: The SC30R12KT is shielded, reducing electromagnetic radiation and susceptibility to external interference. The 9230-96-RC is unshielded, which may result in increased electromagnetic coupling with adjacent components. Shielding selection depends on circuit layout, signal integrity requirements, and EMI/EMC compliance needs.

Q: Do both parts have identical inductance specifications?

A: Yes, both parts specify 120 nH inductance with ±10% tolerance, tested at 25 MHz. The Q factor is identical at 40 @ 25 MHz. Self-resonant frequencies are within 10 MHz of each other (640 MHz vs. 650 MHz), indicating equivalent high-frequency performance characteristics.

Q: What is the difference in DC resistance between these parts?

A: The SC30R12KT has a maximum DC resistance of 90 mOhm, while the 9230-96-RC has a maximum DC resistance of 80 mOhm. The lower DCR of the 9230-96-RC results in reduced resistive losses and lower heat generation at equivalent current levels.

Q: Are both parts RoHS compliant?

A: Yes, both the SC30R12KT and 9230-96-RC are ROHS3 compliant, meeting current environmental and hazardous substance restrictions for electronic components.
