Equivalent & Substitute Parts for Bourns 9310-16-RC

Part Overview

The Bourns 9310-16-RC is a 1.5 µH unshielded drum core wirewound inductor rated for 600 mA with a maximum DC resistance of 500mOhm. This through-hole axial component operates across a temperature range of -55°C to 105°C and is ROHS3 compliant. The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Engineering Selection Recommendations

For applications requiring ROHS3 compliance, the API Delevan 1537R-16K is the primary substitute for the Bourns 9310-16-RC. This part maintains identical electrical specifications, meets all mechanical compatibility requirements, and provides an extended operating temperature range to 125°C. The 1537R-16K is currently in active production status with 685 units available in inventory.

The API Delevan ER1537-16KM and ER1537-16KP are functionally equivalent alternatives with identical inductance, tolerance, current rating, and DC resistance specifications. However, both parts are RoHS non-compliant. These options are suitable only for applications where RoHS compliance is not required. Both are in active production status with 997 and 843 units available respectively.

All three substitute parts are packaged in Tape & Reel format and maintain the same axial through-hole configuration as the original component.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537R-16K directly replace the Bourns 9310-16-RC?

A: Yes. The 1537R-16K meets all critical electrical parameters (1.5 µH inductance, ±10% tolerance, 600 mA minimum current rating, 500mOhm maximum DC resistance) and maintains identical physical dimensions and mounting configuration. The extended temperature range to 125°C provides additional operational margin.

Q: What is the difference between the three API Delevan substitute parts?

A: The 1537R-16K is ROHS3 compliant with a 670 mA current rating and -55°C to 125°C operating range. The ER1537-16KM and ER1537-16KP are RoHS non-compliant variants with 600 mA current ratings and -55°C to 105°C operating ranges. All three share identical inductance, tolerance, DC resistance, and physical dimensions.

Q: Are there packaging differences between the original and substitute parts?

A: The Bourns 9310-16-RC packaging format is not specified in the available data. The API Delevan substitutes are supplied in Tape & Reel packaging. Verify packaging compatibility with your procurement and assembly requirements.

Q: Which substitute should I select for new designs?

A: For new designs, the API Delevan 1537R-16K is the recommended choice due to its ROHS3 compliance status and active production status. This part meets all electrical and mechanical requirements of the original component.

Q: Can I use the ER1537-16KM or ER1537-16KP if RoHS compliance is not required?

A: Yes. Both parts are electrically and mechanically compatible with the original specification. Selection between these two variants should be based on your specific procurement and supply chain requirements, as both are in active production.
