Bourns 9250-685-RC Equivalent & Substitute Parts

Part Overview

The Bourns 9250-685-RC is a 6.8 mH shielded drum core wirewound inductor rated for 27 mA maximum current with 111 Ohm DC resistance. This through-hole axial component operates across -55°C to 105°C and is designed for applications requiring fixed inductance with ferrite core shielding. The 9250-685-RC has reached obsolete product status, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 9250-685-RC is determined by the following critical parameters:

  • Inductance Value: 6.8 mH (±10% tolerance)
  • Current Rating: 27 mA minimum
  • DC Resistance: 111 Ohm maximum
  • Shielding Type: Shielded ferrite core
  • Mounting Configuration: Through-hole axial
  • Physical Envelope: 0.162" Dia x 0.410" L (4.11mm x 10.41mm)
  • Q Factor: 40 @ 250 kHz
  • Self-Resonant Frequency: 660 kHz

The Bourns 9250A-685-RC qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is the transition from drum core to molded construction and active product status, which provides improved long-term availability.

Engineering Selection Recommendations

The Bourns 9250A-685-RC is the direct substitute for the obsolete 9250-685-RC. Both components maintain identical electrical specifications including inductance, current rating, DC resistance, and frequency characteristics. The 9250A-685-RC offers an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) and active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and REACH unaffected status. The transition from drum core to molded construction in the 9250A series does not affect electrical performance or mechanical compatibility within the specified axial through-hole footprint.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-685-RC be used as a direct replacement for the 9250-685-RC?

A: Yes. The 9250A-685-RC matches all critical electrical parameters: 6.8 mH inductance, 27 mA current rating, 111 Ohm maximum DC resistance, and identical physical dimensions (0.162" Dia x 0.410" L). Both components are shielded ferrite core inductors with axial through-hole mounting.

Q: What is the difference between the drum core and molded construction?

A: The 9250-685-RC uses drum core construction while the 9250A-685-RC uses molded construction. Both achieve identical electrical performance and maintain the same physical envelope and mounting compatibility.

Q: Does the extended temperature range of the 9250A-685-RC affect compatibility?

A: No. The 9250A-685-RC operating range of -55°C to 125°C encompasses the original -55°C to 105°C specification. Extended temperature capability does not impact circuit compatibility.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 9250-685-RC and 9250A-685-RC are ROHS3 compliant and REACH unaffected.

Q: What is the primary reason to transition from the 9250-685-RC to the 9250A-685-RC?

A: The 9250-685-RC is obsolete. The 9250A-685-RC is an active product with ongoing manufacturing support and availability, making it the recommended choice for new designs and ongoing procurement.
