Murata Power Solutions 17333C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 17333C is a 33 µH unshielded wirewound inductor rated for 1 A continuous current with a maximum DC resistance of 130 mOhm. This through-hole radial component operates across a temperature range of 0°C to 70°C and is designed for applications requiring fixed inductance values in compact radial configurations. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent inductance values, similar current ratings, compatible package geometries, and matching compliance certifications are available from alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the 17333C is determined by the following critical parameters:

  • Inductance Value: Must be 33 µH with ±10% tolerance
  • Package Configuration: Must be radial, vertical cylinder through-hole mounting
  • Shielding Type: Must be unshielded
  • Compliance: Must maintain RoHS3 compliance and REACH unaffected status
  • Current Handling: Substitute must support minimum current requirements for the application

The Bourns Inc. RLB0712-330KL meets these substitution criteria with matching inductance, package type, shielding classification, and regulatory compliance. Differences in current rating, DC resistance, and operating temperature range reflect design variations between manufacturers but do not preclude functional substitution when application requirements permit.

Engineering Selection Recommendations

Both the Murata 17333C and Bourns RLB0712-330KL maintain Active product status and satisfy RoHS3 and REACH compliance requirements. Selection between these parts depends on application-specific current demands and operating temperature constraints. The 17333C supports 1 A continuous current within a 0°C to 70°C operating window, while the RLB0712-330KL is rated for 600 mA with an extended temperature range of -40°C to 105°C. DC resistance values differ by 20 mOhm, which may impact thermal performance in high-current applications. Both components are through-hole radial configurations suitable for PCB integration without mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the Bourns RLB0712-330KL directly replace the Murata 17333C in all applications?

A: Direct substitution is valid when application current requirements do not exceed 600 mA. If the circuit demands the full 1 A rating of the 17333C, the Bourns substitute is not appropriate without circuit redesign or thermal management modifications.

Q: What is the significance of the 20 mOhm difference in DC resistance?

A: The RLB0712-330KL exhibits 150 mOhm maximum DCR compared to the 17333C at 130 mOhm maximum. This 15% increase in resistance results in proportionally higher resistive losses at equivalent current levels. For applications sensitive to power dissipation, this difference must be evaluated against thermal budgets.

Q: Are the physical dimensions compatible for PCB layout?

A: Both components are radial, vertical cylinder packages with similar footprints. The 17333C measures 0.283" diameter by 0.413" height, while the RLB0712-330KL measures 0.264" diameter by 0.433" height. These dimensional variations are within typical PCB layout tolerances for radial through-hole components.

Q: Do both parts support the same operating temperature range?

A: No. The 17333C operates from 0°C to 70°C, while the RLB0712-330KL operates from -40°C to 105°C. Applications requiring operation below 0°C or above 70°C must use the Bourns component or identify alternative suppliers.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No regulatory differentiation exists between the two components.
