Equivalent & Substitute Parts for 9310-36-RC

Part Overview

The Bourns 9310-36-RC is a 10 µH unshielded drum core wirewound inductor rated for 445 mA with a maximum DC resistance of 900 mOhm. This through-hole axial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance in compact form factors. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the 9310-36-RC is determined by the following critical parameters:

• Inductance Value: Must be 10 µH with ±10% tolerance
• Mounting Type: Through hole axial configuration required
• Package / Case: Axial form factor
• Core Material & Type: Ferrite or iron core construction acceptable
• Shielding: Unshielded configuration
• Current Rating: Must support minimum 445 mA operation
• DC Resistance: Maximum 900 mOhm acceptable
• Operating Temperature Range: Must cover -55°C to 105°C or equivalent

Two substitute parts meet these criteria with varying performance characteristics:

B78108S1103K000 (EPCOS - TDK Electronics): Direct functional equivalent with enhanced current rating (680 mA) and improved DC resistance (490 mOhm). Active product status with ROHS3 compliance.

1537R-36K (API Delevan Inc.): Mechanical and electrical equivalent with identical current rating (335 mA) and DC resistance (900 mOhm) to the original. Molded construction with iron core. Active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

B78108S1103K000 is suitable for applications where enhanced current handling (680 mA vs. 445 mA) and reduced DC resistance (490 mOhm vs. 900 mOhm) provide performance benefits. This part is active and ROHS3 compliant. Operating temperature range is not specified; verification against application requirements is necessary.

1537R-36K provides mechanical and electrical compatibility with identical DC resistance and operating temperature range (-55°C to 105°C). Current rating is 335 mA, which is below the original 445 mA specification. This part is active and ROHS3 compliant. Selection depends on whether the lower current rating is acceptable for the application.

Both substitutes are through-hole axial components with 10 µH inductance and ±10% tolerance, meeting core substitution criteria. Dimensional variations are minimal and within typical PCB layout tolerances.

Frequently Asked Questions (FAQ)

Q: Can B78108S1103K000 replace 9310-36-RC in all applications?

A: B78108S1103K000 meets the inductance, tolerance, mounting type, and package requirements. It provides superior current handling and lower DC resistance. Operating temperature range is not specified; confirm compatibility with your application's temperature requirements before selection.

Q: Is 1537R-36K suitable if my circuit requires 445 mA?

A: 1537R-36K is rated for 335 mA, which is below the original 445 mA specification. Selection depends on your actual circuit current requirements. If 445 mA is mandatory, B78108S1103K000 (680 mA rating) is the appropriate choice.

Q: Are there dimensional compatibility concerns?

A: B78108S1103K000 dimensions are 0.157" Dia x 0.362" L versus the original 0.156" Dia x 0.375" L. These differences are minimal and typically accommodated in standard through-hole PCB layouts. 1537R-36K has identical dimensions to the original part.

Q: Do all substitutes meet RoHS compliance?

A: Yes. Both B78108S1103K000 and 1537R-36K are ROHS3 compliant, matching the original part's compliance status.

Q: What is the difference between ferrite and iron core construction?

A: Both materials are acceptable for this inductance value and application class. Ferrite cores (used in B78108S1103K000) and iron cores (used in 1537R-36K) provide the required 10 µH inductance with ±10% tolerance. Core material selection does not affect substitution eligibility based on the specified parameters.
