Bourns 9310-14 Equivalent & Substitute Parts

Part Overview

The Bourns 9310-14 is a 1.2 µH unshielded drum core wirewound inductor rated for 650 mA with a maximum DC resistance of 420mOhm. This through-hole axial component operates across the temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance with tight tolerance specifications.

The 9310-14 has reached obsolete product status. Identifying qualified substitute parts ensures design continuity and maintains supply chain reliability for existing applications and new production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 9310-14 are qualified based on the following electrical and mechanical parameters:

• Inductance Value: 1.2 µH (exact match required)
• Inductance Tolerance: ±10% (exact match required)
• DC Resistance: 420mOhm maximum (exact match required)
• Current Rating: Minimum 650 mA (equal or higher acceptable)
• Q Factor: 33 @ 7.9MHz (exact match required)
• Self Resonant Frequency: 180MHz (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Physical Dimensions: 0.156" Dia x 0.375" L (exact match required)

All substitute parts are manufactured by API Delevan Inc. and feature molded construction with phenolic core material, compared to the original drum core ferrite design. All substitutes maintain identical electrical performance at the specified test frequency and operating temperature ranges compatible with the original application.

Parameter Comparison

Engineering Selection Recommendations

All four API Delevan substitute parts maintain active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Bourns 9310-14.

API Delevan 1537-14K provides the highest current rating at 730 mA and extends the operating temperature range to 125°C, offering enhanced thermal margin for applications requiring higher current capacity or wider temperature operation.

API Delevan ER1537-14KM, ER1537-14KP, and ER1537-14KR are functionally equivalent to the original 9310-14, each rated for 650 mA with identical electrical specifications and operating temperature range of -55°C to 105°C. These three variants differ only in packaging designation and are available in Tape & Reel format for automated assembly processes.

All substitute parts share identical inductance, tolerance, DC resistance, Q factor, self-resonant frequency, and physical dimensions with the original component. The transition from drum core ferrite to molded phenolic core construction maintains electrical performance while supporting active manufacturing and distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-14K be used as a direct replacement for the Bourns 9310-14?

A: Yes. The 1537-14K meets all electrical specifications of the 9310-14 and provides additional current capacity at 730 mA versus 650 mA. The higher current rating does not affect circuit operation in applications designed for the original 650 mA rating. The extended operating temperature range to 125°C provides additional thermal margin.

Q: What is the difference between ER1537-14KM, ER1537-14KP, and ER1537-14KR?

A: These three parts are electrically and mechanically identical. The letter suffix designates different packaging configurations or manufacturing batches within the ER1537 series. All three are available in Tape & Reel format and are suitable for automated assembly.

Q: Are the substitute parts physically compatible with the original PCB layout?

A: Yes. All substitute parts maintain the identical axial package dimensions of 0.156" diameter by 0.375" length (3.96mm x 9.53mm). Through-hole lead spacing and component footprint are unchanged, allowing direct board-level substitution without layout modifications.

Q: What is the impact of the core material change from ferrite to phenolic?

A: The electrical performance at the specified test frequency of 7.9MHz remains identical. Both core materials achieve the same inductance value, Q factor, and self-resonant frequency. The phenolic core construction in the API Delevan parts supports active manufacturing and maintains long-term supply availability.

Q: Are all substitute parts available in the same packaging format?

A: The original Bourns 9310-14 packaging format is not specified in the technical data. All API Delevan substitutes are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes and provides improved handling and storage compared to bulk packaging.

Q: Do the substitute parts meet the same compliance standards as the original?

A: All substitute parts share identical RoHS non-compliance status, REACH unaffected classification, and EAR99 ECCN designation with the original Bourns 9310-14. Compliance profiles are equivalent across all parts in this substitution group.
