Bourns 9230-94 100nH Axial Inductor Equivalent & Substitute Parts

Part Overview

The Bourns 9230-94 is a 100nH unshielded molded inductor rated for 1.1A continuous current with 70mOhm maximum DC resistance. This through-hole axial component operates across -55°C to 105°C and is designed for high-frequency applications up to 690MHz self-resonant frequency.

The 9230-94 carries obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 9230-94 are classified based on strict electrical and mechanical parameter alignment:

Direct Equivalent (Identical Specifications): The 9230-94-RC maintains all core electrical parameters: 100nH inductance, ±10% tolerance, 1.1A current rating, 70mOhm DCR, unshielded construction, and identical physical dimensions. This part qualifies as a direct substitute with no performance trade-offs. The primary distinction is packaging format (Bulk vs. standard) and product status (Active vs. Obsolete).

Similar Substitute (Parameter Variance Allowed): The 1025-94K shares the same inductance value (100nH), tolerance (±10%), shielding type (unshielded), mounting configuration (through-hole axial), and physical dimensions (0.095" Dia x 0.250" L). Acceptable parameter variations include higher current rating (1.38A vs. 1.1A), increased DCR (80mOhm vs. 70mOhm), and extended operating temperature range (-55°C to 125°C vs. -55°C to 105°C). These variations represent performance enhancements or equivalent capability within the same functional class.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required): The 9230-94-RC is the primary substitute for the obsolete 9230-94. Both parts are manufactured by Bourns Inc. and share identical electrical and mechanical specifications. The 9230-94-RC is currently in active production status with 3133 units in stock. Selection of the 9230-94-RC eliminates obsolescence risk while maintaining full design compatibility. The 9230-94-RC achieves ROHS3 compliance, providing regulatory advantage over the original non-compliant part.

For Applications Requiring Extended Temperature Range or Higher Current Margin: The 1025-94K from API Delevan Inc. qualifies as a functional substitute when design parameters permit the noted variations. This part offers 1.38A current rating (25.5% higher than the 1.1A original specification), extended operating temperature to 125°C (versus 105°C), and maintains the same 100nH inductance and ±10% tolerance. The 1025-94K carries military qualification (MIL-PRF-M15305, MS75083) and is actively produced with 1457 units in stock. The 80mOhm DCR represents a 14.3% increase over the 70mOhm specification; this variance is acceptable in applications where the original 70mOhm DCR was not a critical design constraint. The 680MHz self-resonant frequency is 1.4% lower than the 690MHz original value and remains suitable for the same frequency range applications.

Frequently Asked Questions (FAQ)

Q: Can the 9230-94-RC be used as a direct drop-in replacement for the 9230-94?

A: Yes. The 9230-94-RC is electrically and mechanically identical to the 9230-94. Both parts feature 100nH inductance, ±10% tolerance, 1.1A current rating, 70mOhm DCR, unshielded construction, and identical axial package dimensions (0.095" Dia x 0.250" L). No circuit modifications or board layout changes are required. The primary advantage is active production status and ROHS3 compliance.

Q: What are the key differences between the 9230-94-RC and the 1025-94K?

A: Both parts maintain 100nH inductance, ±10% tolerance, unshielded axial configuration, and identical physical dimensions. The 1025-94K offers higher current rating (1.38A vs. 1.1A), extended temperature range (-55°C to 125°C vs. -55°C to 105°C), and slightly higher DCR (80mOhm vs. 70mOhm). The 1025-94K is manufactured by API Delevan Inc. and carries military qualification. The 9230-94-RC is manufactured by Bourns Inc. and achieves ROHS3 compliance.

Q: Is the 1025-94K suitable for applications originally designed for the 9230-94?

A: The 1025-94K is suitable when the application does not require the original 70mOhm DCR specification as a hard limit. The 80mOhm DCR represents acceptable performance variance for most general-purpose RF and high-frequency applications. The higher current rating (1.38A) and extended temperature range provide design margin. If the original design specifically required 70mOhm DCR or operated at the upper temperature limit of 105°C, the 9230-94-RC is the preferred choice.

Q: Are there packaging format differences between these parts?

A: The 9230-94-RC is supplied in Bulk packaging, while the 1025-94K is supplied in Cut Tape (CT) format. Both formats are compatible with standard through-hole assembly processes. Packaging selection depends on production volume and assembly equipment compatibility.

Q: What is the compliance status of each substitute part?

A: The 9230-94-RC achieves ROHS3 compliance. Both the original 9230-94 and the 1025-94K are RoHS non-compliant. All three parts are REACH Unaffected and classified as EAR99 for export control purposes.
