Bourns 9310-00 Equivalent & Substitute Parts

Part Overview

The Bourns 9310-00 is a 150 nH unshielded drum core wirewound inductor rated for 2.45 A with a maximum DC resistance of 30 mOhm. This through-hole axial component operates across -55°C to 105°C and is designed for applications requiring low inductance values with moderate current handling. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the Bourns 9310-00 is determined by strict equivalence across the following critical parameters:

Inductance value: 150 nH with ±20% tolerance
Current rating: minimum 2.45 A
DC resistance: maximum 30 mOhm
Shielding configuration: unshielded
Electrical performance: Q factor of 50 @ 25 MHz and self-resonant frequency of 525 MHz
Physical form factor: through-hole axial mounting with 0.156" diameter x 0.375" length
Operating temperature range: minimum -55°C to 105°C

The API Delevan 1537-00M and 1537R-00M meet all electrical and mechanical substitution criteria. Both parts maintain identical inductance, tolerance, DC resistance, Q factor, and self-resonant frequency specifications. The 1537-00M and 1537R-00M exceed the current rating requirement at 2.74 A and extend the upper operating temperature to 125°C, providing enhanced performance margins.

Engineering Selection Recommendations

The Bourns 9310-00 is obsolete and no longer in active production. Both API Delevan substitutes are active products with current availability.

The API Delevan 1537-00M is supplied in cut tape packaging and is RoHS non-compliant, matching the compliance status of the original Bourns part.

The API Delevan 1537R-00M is supplied in tape and reel packaging and is RoHS3 compliant, providing regulatory advantage for new designs and applications with RoHS requirements.

Both substitutes provide superior current handling capacity (2.74 A versus 2.45 A) and extended upper operating temperature (125°C versus 105°C), ensuring compatibility with the original design specifications while offering improved performance margins.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537-00M and 1537R-00M be used interchangeably with the Bourns 9310-00?

A: Yes. Both parts meet all electrical and mechanical specifications required for direct substitution. The primary difference is packaging format: 1537-00M is supplied in cut tape, while 1537R-00M is supplied in tape and reel.

Q: What is the difference between the 1537-00M and 1537R-00M?

A: Both parts are electrically and mechanically identical. The 1537-00M is packaged in cut tape format and is RoHS non-compliant. The 1537R-00M is packaged in tape and reel format and is RoHS3 compliant. Selection depends on packaging requirements and regulatory compliance needs.

Q: Are there any performance differences between the Bourns 9310-00 and the API Delevan substitutes?

A: The API Delevan parts exceed the original specifications. They provide 0.29 A additional current capacity and 20°C higher maximum operating temperature, while maintaining identical inductance, DC resistance, Q factor, and self-resonant frequency.

Q: Will the physical dimensions of the substitute parts fit existing PCB layouts?

A: Yes. All three parts share identical physical dimensions of 0.156" diameter x 0.375" length and use the same through-hole axial mounting configuration.

Q: Which substitute should be selected for new designs?

A: Selection is based on packaging and compliance requirements. For applications requiring RoHS3 compliance, use the 1537R-00M. For applications without RoHS requirements or where cut tape packaging is preferred, use the 1537-00M.
