Bourns 9230-92-RC Fixed Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9230-92-RC is a 1 mH unshielded molded inductor rated for 38 mA maximum current with 72 Ohm maximum DC resistance. This through-hole axial component operates across the temperature range of -55°C to 125°C and is designed for applications requiring ferrite core inductors with tight tolerance specifications. The part is currently active in production and RoHS3 compliant. Substitute parts may be required due to inventory constraints, regional availability, or specific compliance requirements for legacy or military-grade applications.

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-92-RC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1 mH (exact match required)
• Inductance tolerance: ±10% (exact match required)
• Core material: Ferrite (exact match required)
• DC resistance: 72 Ohm maximum (exact match required)
• Q factor @ 790 kHz: 30 (exact match required)
• Self-resonant frequency: 3.4 MHz (exact match required)
• Shielding: Unshielded (exact match required)
• Package type: Axial (exact match required)
• Mounting type: Through Hole (exact match required)
• Physical dimensions: 0.095" Dia × 0.250" L (exact match required)

Secondary Consideration:

• Current rating: The main part is rated for 38 mA. Substitute parts with lower current ratings (28 mA) may be used in applications where the circuit current does not exceed the substitute part's rating.

The identified substitute parts (1025-92K and ER1025-92KR) meet all primary matching criteria. Both are API Delevan Inc. manufactured inductors with identical electrical and mechanical specifications to the main part, with the exception of current rating and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Bourns 9230-92-RC (Primary Part): Use this part for applications requiring RoHS3 compliance and operating temperatures up to 125°C. The 38 mA current rating provides margin for higher-current circuit designs. This part is the preferred choice for commercial and industrial applications with modern compliance requirements.

API Delevan 1025-92K (Substitute - Bulk Packaging): This substitute is suitable for applications where RoHS compliance is not required and operating temperature does not exceed 105°C. The 28 mA current rating limits use to lower-current circuit designs. This part is available in bulk packaging and carries military series designation (MIL-PRF-M15305, MS75085), making it appropriate for legacy or military-specification applications.

API Delevan ER1025-92KR (Substitute - Cut Tape Packaging): This substitute is functionally equivalent to the 1025-92K but is supplied in cut tape packaging format. It carries military series designation (MIL-PRF-39010/10, ER1025) and is suitable for the same applications as the 1025-92K, with the added benefit of tape packaging for automated assembly processes. RoHS non-compliance and 105°C maximum operating temperature apply.

Compliance Considerations: Substitution from the RoHS3-compliant Bourns 9230-92-RC to either API Delevan part represents a change in compliance status. This substitution is only permissible in designs where RoHS compliance is not a contractual or regulatory requirement.

Temperature Considerations: The Bourns 9230-92-RC operates to 125°C, while both API Delevan substitutes are limited to 105°C. Substitution is only valid for applications where the maximum operating temperature does not exceed 105°C.

Current Rating Considerations: The Bourns 9230-92-RC is rated for 38 mA, while both API Delevan substitutes are rated for 28 mA. Substitution is only valid for applications where the maximum circuit current does not exceed 28 mA.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025-92K be used as a direct replacement for the Bourns 9230-92-RC?

A: The API Delevan 1025-92K is electrically and mechanically compatible with the Bourns 9230-92-RC for applications where three conditions are met: (1) the circuit current does not exceed 28 mA, (2) the operating temperature does not exceed 105°C, and (3) RoHS3 compliance is not required. If any of these conditions cannot be met, the Bourns part must be used.

Q: What is the difference between the API Delevan 1025-92K and ER1025-92KR?

A: Both parts are electrically and mechanically identical. The primary difference is packaging format: the 1025-92K is supplied in bulk packaging, while the ER1025-92KR is supplied in cut tape (CT) format. The ER1025-92KR is designed for automated assembly processes, while the 1025-92K is suitable for manual assembly or bulk component storage.

Q: Why do the API Delevan substitutes have a lower current rating than the Bourns part?

A: The current rating difference (38 mA vs. 28 mA) reflects design variations between manufacturers. The lower rating on the API Delevan parts indicates a more conservative thermal design margin. Substitution is valid only when the application current requirement does not exceed 28 mA.

Q: Are the API Delevan parts RoHS compliant?

A: No. Both API Delevan parts (1025-92K and ER1025-92KR) are RoHS non-compliant. The Bourns 9230-92-RC is RoHS3 compliant. Substitution to either API Delevan part is only permissible in applications where RoHS compliance is not required.

Q: What is the maximum operating temperature for each part?

A: The Bourns 9230-92-RC operates from -55°C to 125°C. Both API Delevan substitutes (1025-92K and ER1025-92KR) operate from -55°C to 105°C. Substitution is valid only for applications where the maximum operating temperature does not exceed 105°C.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical physical dimensions of 0.095" diameter × 0.250" length (2.41 mm × 6.35 mm). They are all axial through-hole components and are mechanically interchangeable in terms of board layout and mounting.

Q: Can I use the ER1025-92KR in manual assembly applications?

A: Yes. Although the ER1025-92KR is supplied in cut tape packaging optimized for automated assembly, it can be used in manual assembly applications. The cut tape format does not prevent manual handling or insertion.
