Equivalent & Substitute Parts for Bourns 9310-07-RC

Part Overview

The Bourns 9310-07-RC is a 560 nH unshielded drum core wirewound inductor rated for 1.22 A with a maximum DC resistance of 135 mOhm. This through-hole axial component operates across a temperature range of -55°C to 105°C and is designed for applications requiring fixed inductance at 25 MHz. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new designs requiring compatible specifications.

• DC resistance: maximum 135 mOhm
• Quality factor: 50 @ 25 MHz
• Self resonant frequency: 280 MHz
• Operating temperature range: minimum -55°C to 105°C
• Mounting configuration: through-hole axial
• Physical dimensions: 0.156" Dia x 0.375" L
• Shielding classification: unshielded

The API Delevan 1537R-07K meets all substitution criteria while maintaining electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 1537R-07K is a direct functional equivalent for the obsolete Bourns 9310-07-RC. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute part exceeds the original specifications in current rating (1.29 A versus 1.22 A) and operating temperature range (-55°C to 125°C versus -55°C to 105°C), providing enhanced performance margins without compromising electrical characteristics. All critical parameters including inductance, tolerance, DC resistance, quality factor, and self resonant frequency are identical. Physical dimensions and mounting configuration are fully compatible, enabling direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 1537R-07K replace the Bourns 9310-07-RC in existing designs?

A: Yes. The substitute part meets all electrical and mechanical specifications of the original component. Identical inductance, tolerance, DC resistance, and frequency characteristics ensure functional equivalence. Physical dimensions and axial through-hole mounting are identical, permitting direct substitution without PCB modification.

Q: What are the key differences between these two inductors?

A: The primary differences are manufacturer, core material (ferrite versus phenolic), and construction type (drum core wirewound versus molded). The API Delevan part provides higher current rating (1.29 A versus 1.22 A) and extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). All electrical performance parameters remain equivalent.

Q: Are there packaging differences between these parts?

A: The Bourns 9310-07-RC is supplied in standard packaging, while the API Delevan 1537R-07K is supplied in Tape & Reel (TR) format. Both maintain identical component dimensions and axial configuration. Tape & Reel packaging is standard for active production components and does not affect electrical or mechanical compatibility.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the Bourns 9310-07-RC and API Delevan 1537R-07K are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the temperature operating range difference, and does it matter for my application?

A: The API Delevan 1537R-07K operates from -55°C to 125°C, while the Bourns part operates from -55°C to 105°C. If your application requires operation above 105°C, the substitute part provides additional thermal margin. For applications within the original -55°C to 105°C range, both parts are functionally equivalent.
