Bourns 9230-00 150nH Through-Hole Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9230-00 is a 150nH unshielded molded inductor rated for 1.1A continuous current with 100mOhm maximum DC resistance, designed for through-hole axial mounting. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The 9230-00-RC represents the active production equivalent from the same manufacturer, while alternative suppliers offer functionally compatible options with enhanced specifications or compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria (Must Match):

• Inductance value: 150 nH
• Inductance tolerance: ±10%
• Mounting type: Through Hole
• Package type: Axial
• DC Resistance: 100 mOhm maximum

Secondary Substitution Criteria (Must Equal or Exceed):

• Current rating: minimum 1.1 A
• Operating temperature range: must cover -55°C to 105°C minimum
• Self resonant frequency: 600 MHz or higher
• Q factor @ 25 MHz: 38 or higher

Acceptable Variations:

• Shielding type (unshielded to shielded acceptable; shielded to unshielded not acceptable for EMI-sensitive circuits)
• Physical dimensions (within axial through-hole form factor)
• Core material (phenolic or equivalent)
• RoHS and REACH compliance status

The 9230-00-RC qualifies as a direct equivalent with identical electrical specifications and improved compliance status. The 1025-00K and SC30R15KT qualify as similar substitutes with enhanced current ratings and maintained electrical performance.

Parameter Comparison

Engineering Selection Recommendations

9230-00-RC (Bourns Inc.): This is the recommended primary substitute. It maintains identical electrical specifications and physical form factor while offering active product status and ROHS3 compliance. Selection of this part eliminates obsolescence risk and aligns with modern environmental regulations.

1025-00K (API Delevan Inc.): This substitute provides enhanced current rating (1.23A versus 1.1A) and extended operating temperature range to 125°C. It qualifies as a military-grade component per MIL-PRF-M15305 and MS75083 specifications. Selection is appropriate for applications requiring higher current margin or military-specification compliance, though RoHS non-compliance must be evaluated against procurement requirements.

SC30R15KT (TE Connectivity): This substitute offers the highest current rating (1.33A) and includes shielding, which provides EMI rejection benefits. Physical dimensions are larger (0.165" diameter versus 0.095"), requiring PCB layout verification. ROHS3 compliance is provided. Selection is appropriate for noise-sensitive applications where shielding provides circuit performance advantages, provided board space accommodates the larger form factor.

Frequently Asked Questions (FAQ)

Q: Can the 9230-00-RC be used as a direct replacement for the obsolete 9230-00?

A: Yes. The 9230-00-RC is electrically and mechanically identical to the 9230-00, with the addition of ROHS3 compliance and active product status. No circuit modifications are required.

Q: What is the primary difference between the 1025-00K and the main part?

A: The 1025-00K provides 0.13A additional current rating (1.23A versus 1.1A) and extends the maximum operating temperature to 125°C. It is manufactured to military specifications. Electrical performance at nominal operating conditions is equivalent.

Q: Why is the SC30R15KT larger than the other options?

A: The SC30R15KT incorporates shielding to reduce electromagnetic interference. Shielded inductors require larger physical dimensions to accommodate the shielding structure. The 0.165" diameter and 0.394" length must be verified against PCB layout constraints before selection.

Q: Can the shielded SC30R15KT replace an unshielded inductor in any application?

A: Shielded inductors can replace unshielded inductors in most applications and provide additional EMI rejection. However, the larger physical dimensions must fit within available board space. Unshielded inductors cannot replace shielded inductors in applications where shielding is required for circuit performance.

Q: Which substitute offers the best compliance profile?

A: Both the 9230-00-RC and SC30R15KT offer ROHS3 compliance. The 9230-00-RC is recommended for standard applications, while the SC30R15KT is recommended when shielding provides additional circuit benefits.

Q: Are there packaging differences between these substitutes?

A: Yes. The 9230-00-RC is supplied in bulk packaging, the 1025-00K in cut tape, and the SC30R15KT in tape and box. Packaging selection depends on procurement volume and handling requirements.

Q: What is the temperature range limitation for the SC30R15KT?

A: The SC30R15KT operates from -55°C to 100°C, which is 5°C lower than the original 9230-00 specification of 105°C maximum. Applications requiring operation above 100°C must use the 9230-00-RC or 1025-00K.
