Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 9220-12 is determined by the following critical parameters:

• Inductance Value: 470 µH with ±5% tolerance
• Current Rating: Minimum 95 mA capability
• DC Resistance: Maximum 11.1 Ohm
• Mounting Configuration: Through-hole axial package
• Physical Dimensions: 0.190" diameter x 0.440" length
• Operating Temperature Range: -55°C to 105°C
• Shielding Classification: Unshielded

The API Delevan 2500-12J meets these substitution criteria with equivalent inductance, tolerance, and operating temperature specifications. While the substitute features an iron core molded construction versus the ferrite drum core design, both configurations deliver the required electrical performance within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 2500-12J provides functional equivalence to the obsolete Bourns 9220-12 across all critical electrical and mechanical parameters. The substitute component offers improved current rating capacity (108 mA versus 95 mA) and maintains equivalent DC resistance specifications. Both components share identical operating temperature ranges, physical dimensions, and axial through-hole mounting configuration, enabling direct board-level substitution.

The API Delevan part maintains active product status, ensuring ongoing availability and supply chain continuity. Both components carry identical RoHS and REACH compliance classifications. The molded iron core construction of the substitute provides equivalent performance to the ferrite drum core design within the specified parameter tolerances.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 2500-12J directly replace the Bourns 9220-12 on existing circuit boards?

A: Yes. Both components share identical physical dimensions (0.190" diameter x 0.440" length), axial through-hole mounting configuration, and footprint requirements. No board layout modifications are necessary.

Q: What is the difference between the ferrite drum core and iron molded core designs?

A: The Bourns 9220-12 uses ferrite drum core wirewound construction, while the API Delevan 2500-12J employs molded iron core technology. Both deliver equivalent inductance values, tolerance specifications, and DC resistance within the defined parameter envelope.

Q: Does the higher current rating of the substitute part affect circuit operation?

A: No. The API Delevan 2500-12J current rating of 108 mA exceeds the original 95 mA specification, providing additional design margin. This represents an improvement in component capability without altering circuit behavior.

Q: Are there compliance or certification differences between these components?

A: Both components share identical RoHS non-compliance and REACH unaffected classifications. No compliance advantages or disadvantages exist between the two parts.

Q: What packaging format is available for the API Delevan substitute?

A: The API Delevan 2500-12J is supplied in Cut Tape (CT) packaging format, suitable for both manual and automated assembly processes.
