Bourns 9310-48 Equivalent & Substitute Parts

Part Overview

The Bourns 9310-48 is a 27 µH unshielded drum core wirewound inductor rated for 260 mA with a maximum DC resistance of 2.6Ω. This through-hole axial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance values in compact form factors.

The 9310-48 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 eligibility for the Bourns 9310-48 is determined by the following critical parameters:

• Inductance Value: Must match 27 µH within the specified ±10% tolerance band
• DC Resistance: Must not exceed 2.6Ω maximum
• Current Rating: Substitute must support minimum 260 mA operation
• Q Factor & Self Resonant Frequency: Must maintain 60 @ 2.5 MHz and 25 MHz respectively
• Operating Temperature Range: Must cover -55°C to 105°C
• Physical Form Factor: Axial through-hole mounting with compatible dimensions (0.156" Dia × 0.375" L)
• Shielding Configuration: Unshielded topology

The API Delevan 1537-47K meets these substitution criteria with equivalent electrical performance across all specified parameters, despite differences in core material (iron vs. ferrite) and construction type (molded vs. drum core).

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537-47K serves as a functional equivalent to the obsolete Bourns 9310-48 based on the following engineering criteria:

Electrical Equivalence: Both components deliver identical inductance (27 µH ±10%), DC resistance (2.6Ω max), Q factor (60 @ 2.5 MHz), and self-resonant frequency (25 MHz). Operating temperature ranges are identical (-55°C to 105°C).

Current Rating Consideration: The 1537-47K is rated for 198 mA, which is lower than the 9310-48's 260 mA rating. This difference must be evaluated against actual circuit current requirements. If circuit operation demands exceed 198 mA, the 1537-47K is not suitable.

Product Status & Availability: The 1537-47K maintains active product status with confirmed inventory availability, whereas the 9310-48 is obsolete. This availability advantage supports long-term supply chain continuity.

Compliance & Certifications: Both components share identical RoHS non-compliance status, REACH unaffected classification, and EAR99 ECCN designation.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-47K directly replace the Bourns 9310-48 in all applications?

A: Direct replacement is possible only if circuit current requirements do not exceed 198 mA. The 1537-47K's lower current rating (198 mA vs. 260 mA) is the primary limiting factor. All other electrical parameters—inductance, DC resistance, Q factor, and frequency response—are equivalent.

Q: What is the significance of the different core materials (ferrite vs. iron)?

A: Core material differences affect inductor construction and thermal characteristics but do not alter the specified electrical parameters provided for these components. Both materials deliver the same inductance value, DC resistance, and Q factor at the specified test frequency.

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

A: Yes. Both components share identical axial form factors: 0.156" diameter × 0.375" length (3.96mm × 9.53mm). They are mechanically interchangeable in through-hole PCB layouts.

Q: What packaging options are available for the substitute part?

A: The API Delevan 1537-47K is supplied in Tape & Reel (TR) packaging, whereas the original Bourns 9310-48 packaging specification is not detailed in the provided data. Verify packaging compatibility with your procurement and assembly processes.

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

A: Both components share identical compliance profiles: RoHS non-compliant, REACH unaffected, and EAR99 ECCN classification. No regulatory advantage exists between the two parts.
