Bourns 9310-34 Fixed Inductor: Equivalent & Substitute Parts

Part Overview

The Bourns 9310-34 is an 8.2 µH unshielded drum core wirewound inductor rated for 545 mA with a maximum DC resistance of 600mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors.

The 9310-34 is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 9310-34 is determined by the following critical parameters:

• Inductance Value: Must be 8.2 µH with ±10% tolerance
• DC Resistance: Must not exceed 600mOhm
• Current Rating: Substitute must support minimum 545 mA operation
• Shielding Configuration: Must be unshielded
• Frequency Characteristics: Q factor of 50 @ 7.9MHz and self-resonant frequency of 50MHz
• Operating Temperature: Must support -55°C to 105°C range
• Mounting and Package: Through-hole axial configuration with matching physical dimensions (0.156" Dia x 0.375" L)

The API Delevan 1537-34K meets these substitution criteria with equivalent electrical performance across all critical parameters, despite differences in core material and current rating specification.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-34K is an active product suitable for replacing the obsolete Bourns 9310-34 in applications where the specified electrical parameters are met. Both components share identical inductance values, tolerance, DC resistance, frequency characteristics, and operating temperature range.

The primary design consideration is the current rating differential: the 1537-34K is rated for 410 mA versus the 9310-34's 545 mA specification. Circuit designs operating at or below 410 mA continuous current are directly compatible. Designs requiring the full 545 mA rating must be evaluated for thermal and performance impact with the substitute part.

Both components carry identical RoHS non-compliance and REACH unaffected status. No compliance advantage exists between the two parts.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-34K directly replace the Bourns 9310-34 in all applications?

A: Direct replacement is valid for circuits operating at 410 mA or below. Applications requiring continuous current above 410 mA require circuit re-evaluation with the substitute part's lower current rating.

Q: What is the significance of the core material difference between drum core (ferrite) and molded (iron)?

A: Both configurations deliver the specified inductance value, DC resistance, and frequency characteristics. The core material difference does not affect electrical substitution criteria for this application.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both components measure 0.156" diameter by 0.375" length (3.96mm x 9.53mm), ensuring mechanical compatibility in through-hole axial mounting configurations.

Q: Does the API Delevan part offer any compliance advantages?

A: No. Both parts carry identical RoHS non-compliance and REACH unaffected designations.

Q: What is the inventory status for these components?

A: The Bourns 9310-34 has 1079 pieces in stock as new original inventory. The API Delevan 1537-34K has 1028 pieces in stock as new original inventory, supplied in tape and reel packaging.
