Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 9230-36-RC is determined by the following critical parameters:

Inductance Value: 4.7 µH (exact match required)
Tolerance: ±10% (exact match required)
DC Resistance: 1.2 Ohm Max (exact match required)
Q @ Frequency: 45 @ 7.9 MHz (exact match required)
Self Resonant Frequency: 75 MHz (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Axial (exact match required)
Size / Dimension: 0.095" Dia x 0.250" L (2.41mm x 6.35mm) (exact match required)

The substitute parts API Delevan 1025-36K and 1025R-36K meet all critical electrical and mechanical parameters. Both are available in axial through-hole configuration with identical inductance, tolerance, DC resistance, Q factor, and self-resonant frequency specifications. Physical dimensions are identical. Differences exist in current rating, core material, operating temperature range, packaging format, and compliance certifications.

Engineering Selection Recommendations

API Delevan 1025R-36K is the preferred substitute for the Bourns 9230-36-RC. Both parts are ROHS3 compliant and active in production. The 1025R-36K is available in bulk packaging, matching the original part's packaging format. Both parts are molded inductors with identical electrical specifications across all critical parameters.

API Delevan 1025-36K is an alternative substitute with identical electrical specifications. This part is available in Tape & Reel packaging format and is not ROHS3 compliant. Selection of this part requires confirmation that RoHS non-compliance is acceptable for the application.

Both substitute parts have a maximum operating temperature of 105°C, which is 20°C lower than the Bourns 9230-36-RC. Applications requiring operation above 105°C must use the original Bourns part. Both substitute parts have a current rating of 239 mA, which is 81 mA lower than the original part's 320 mA rating. Applications requiring current levels above 239 mA must use the original Bourns part.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1025R-36K be used as a direct replacement for the Bourns 9230-36-RC?

A: Yes, for applications operating at or below 105°C and requiring current levels at or below 239 mA. Both parts share identical inductance, tolerance, DC resistance, Q factor, self-resonant frequency, and physical dimensions. Verify that your application's current and temperature requirements do not exceed the 1025R-36K specifications.

Q: What is the difference between the API Delevan 1025-36K and 1025R-36K?

A: Both parts have identical electrical specifications. The primary differences are packaging format (1025-36K is Tape & Reel; 1025R-36K is Bulk) and RoHS compliance status (1025-36K is non-compliant; 1025R-36K is ROHS3 compliant). Select based on your packaging requirements and compliance obligations.

Q: Why does the Bourns 9230-36-RC have a higher current rating than the substitute parts?

A: The Bourns part uses a ferrite core, while the API Delevan substitutes use iron cores. This core material difference results in different current handling capabilities while maintaining identical inductance and DC resistance values.

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

A: Yes. All three parts are 0.095" diameter by 0.250" length (2.41mm x 6.35mm) axial through-hole components. They are mechanically interchangeable on PCBs designed for the original part.

Q: What is the impact of the 20°C lower maximum operating temperature on the substitute parts?

A: The API Delevan substitutes operate to 105°C maximum, compared to 125°C for the Bourns part. Applications with maximum operating temperatures above 105°C require the original Bourns 9230-36-RC.

Q: Can I use the 1025-36K in a RoHS-compliant application?

A: No. The 1025-36K is RoHS non-compliant. For RoHS-compliant applications, use either the original Bourns 9230-36-RC or the API Delevan 1025R-36K, both of which are ROHS3 compliant.
