Equivalent & Substitute Parts for 9310-30-RC

Part Overview

The Bourns 9310-30-RC is a 5.6 µH unshielded drum core wirewound inductor rated for 750 mA with a maximum DC resistance of 320mOhm. This through-hole axial component operates across -55°C to 105°C and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 9310-30-RC is determined by the following critical parameters:

• Inductance Value: 5.6 µH (exact match required)
• Tolerance: ±10% (standard tolerance maintained)
• Current Rating: Minimum 750 mA or higher
• DC Resistance: Maximum 320mOhm or lower
• Core Material & Shielding: Ferrite, unshielded configuration
• Mounting & Package: Through-hole axial components only
• Compliance: ROHS3 compliant

The substitute parts identified meet these electrical and mechanical criteria, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

B78108S1562K000 (EPCOS - TDK Electronics): This direct manufacturer substitute maintains ferrite core construction with active product status. Current rating of 780 mA exceeds the original 750 mA specification. DC resistance of 380mOhm is within acceptable tolerance for most applications. Higher self-resonant frequency (85MHz) provides improved high-frequency performance. ROHS3 compliance is confirmed.

1537R-30K (API Delevan Inc.): This substitute features identical DC resistance (320mOhm) and matching physical dimensions to the original part. Core material differs (iron vs. ferrite), resulting in identical Q factor and self-resonant frequency characteristics. Current rating of 565 mA is lower than the original specification and may not be suitable for applications requiring the full 750 mA rating. Active product status and ROHS3 compliance are confirmed.

Frequently Asked Questions (FAQ)

Q: Can B78108S1562K000 replace 9310-30-RC in all applications? A: B78108S1562K000 meets or exceeds all critical electrical parameters. The higher current rating (780 mA vs. 750 mA) and increased DC resistance (380mOhm vs. 320mOhm) are within acceptable substitution margins for standard inductor applications. Ferrite core construction is maintained.

Q: Is 1537R-30K suitable for high-current applications? A: 1537R-30K has a current rating of 565 mA, which is below the original 750 mA specification. This part is suitable only for applications requiring 565 mA or less. The identical DC resistance and physical dimensions make it compatible for lower-current circuit designs.

Q: What is the impact of core material differences between ferrite and iron? A: The 1537R-30K uses an iron core instead of ferrite. Both parts maintain identical inductance values, DC resistance, and self-resonant frequency at 60MHz. Core material selection affects magnetic saturation characteristics and temperature stability, which are not specified in the provided parameters.

Q: Are all substitute parts RoHS3 compliant? A: Yes, both B78108S1562K000 and 1537R-30K are ROHS3 compliant, matching the compliance status of the original 9310-30-RC.

Q: What are the physical dimension tolerances for board layout? A: B78108S1562K000 dimensions are 0.157" Dia x 0.362" L (4.00mm x 9.20mm), which differ slightly from the original 0.156" Dia x 0.375" L (3.96mm x 9.53mm). 1537R-30K maintains identical dimensions to the original part.
