Bourns 9250A-336-RC Equivalent & Substitute Parts

Part Overview

The Bourns 9250A-336-RC is a 33 mH shielded molded inductor rated for 15 mA maximum current with 343 Ohm DC resistance. This through-hole axial component operates across the temperature range of -55°C to 125°C and is designed for applications requiring ferrite-core inductance with electromagnetic shielding.

The 9250A-336-RC is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and redesign applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9250A-336-RC is determined by the following critical parameters:

• Inductance Value: 33 mH (±10% tolerance)
• DC Resistance: 343 Ohm Max
• Current Rating: Minimum 15 mA (equal or greater)
• Saturation Current (Isat): 7.5 mA
• Shielding: Shielded construction required
• Core Material: Ferrite
• Operating Temperature: -55°C to 125°C minimum
• Mounting Type: Through Hole
• Package: Axial

The API Delevan 4307R-336K meets all substitution criteria. It maintains identical inductance, tolerance, DC resistance, saturation current, shielding, core material, operating temperature range, and mounting configuration. The 4307R-336K provides a higher current rating (29 mA versus 15 mA), which is compatible with applications designed for the 9250A-336-RC.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan 4307R-336K is the qualified substitute for the obsolete Bourns 9250A-336-RC. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The 4307R-336K is an active product with confirmed inventory availability, eliminating supply chain risk associated with the obsolete 9250A-336-RC. The substitute maintains electrical equivalence across all critical parameters: inductance value, tolerance, DC resistance, saturation current, quality factor, operating temperature range, and shielding characteristics.

Physical dimensions differ slightly; the 4307R-336K is marginally larger (0.197" diameter versus 0.162" diameter). PCB layout verification is required to confirm fit within existing mechanical constraints. The higher current rating (29 mA) of the substitute provides additional design margin without affecting circuit performance in applications rated for 15 mA operation.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan 4307R-336K replace the Bourns 9250A-336-RC in existing designs?

A: Yes. The 4307R-336K meets all electrical specifications of the 9250A-336-RC, including inductance, tolerance, DC resistance, saturation current, and operating temperature range. Physical dimensions require verification for PCB fit.

Q: What is the primary difference between these two inductors?

A: The 4307R-336K has a higher current rating (29 mA versus 15 mA) and a higher self-resonant frequency (400 kHz versus 190 kHz). Both are functionally equivalent for applications designed for the 9250A-336-RC.

Q: Are there packaging differences?

A: The Bourns 9250A-336-RC is supplied as individual components. The API Delevan 4307R-336K is supplied in Tape & Reel (TR) packaging. Both use through-hole axial mounting.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the 9250A-336-RC and 4307R-336K are ROHS3 compliant and REACH unaffected.

Q: What should be verified before implementing the substitute?

A: Confirm PCB layout accommodates the slightly larger physical dimensions of the 4307R-336K (0.197" diameter versus 0.162" diameter). Verify that the higher self-resonant frequency (400 kHz) does not introduce unintended circuit behavior in the target application frequency range.
