Bourns 9230-70 Fixed Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 9230-70 is a 120 µH unshielded molded inductor rated for 97 mA with 13Ohm maximum DC resistance, designed for through-hole axial mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The 9230 series represents a legacy product line that requires substitution planning for new production runs or field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-70 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 120 µH ±10%
• Inductance tolerance: ±10%
• Core material: Ferrite
• Shielding configuration: Unshielded
• Package type: Axial through-hole
• Physical dimensions: 0.095" Dia × 0.250" L
• Q factor @ 790kHz: 30
• Self resonant frequency: 12MHz
• DC resistance: 13Ohm maximum

Secondary Compatibility Factors:

• Current rating must meet or exceed application requirements
• Operating temperature range must encompass application environment
• Mounting footprint must be identical for direct PCB replacement

The API Delevan 1025-70K meets all primary matching criteria and maintains dimensional and electrical parameter equivalence, with the exception of current rating and maximum operating temperature, which are application-dependent considerations.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1025-70K is an active product with equivalent electrical and mechanical specifications to the obsolete Bourns 9230-70. Both components share identical inductance, tolerance, DC resistance, core material, shielding, Q factor, self-resonant frequency, and physical dimensions.

Selection of the 1025-70K requires verification that application current requirements do not exceed 66 mA, as this represents a reduction from the original 97 mA rating. Additionally, if the application operates at temperatures above 105°C, the narrower operating range of the 1025-70K must be evaluated against actual thermal requirements.

Both components carry identical RoHS non-compliance status, REACH unaffected classification, and EAR99 ECCN designation, ensuring regulatory consistency in substitution.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-70K directly replace the Bourns 9230-70 in existing designs?

A: Direct replacement is possible if application current does not exceed 66 mA and operating temperature remains within -55°C to 105°C. Physical footprint and electrical parameters are identical, enabling direct PCB substitution without layout modification.

Q: What is the significance of the lower current rating on the 1025-70K?

A: The 1025-70K is rated for 66 mA versus the original 97 mA. This parameter must be verified against actual circuit current draw. If circuit current exceeds 66 mA, the substitute component will not meet design specifications.

Q: Are there temperature considerations for substitution?

A: The 1025-70K operates to 105°C maximum, compared to 125°C for the 9230-70. Applications requiring operation above 105°C must retain the original specification or identify alternative sources.

Q: Do both components have identical regulatory compliance?

A: Both components are RoHS non-compliant and REACH unaffected. Regulatory status is identical, and no compliance risk is introduced through substitution.

Q: Is the axial through-hole package identical between both parts?

A: Yes. Both components use identical 0.095" diameter × 0.250" length axial packaging, enabling direct mechanical and electrical substitution without PCB redesign.
