Parameter Comparison

Engineering Selection Recommendations

The 9250A-184-RC qualifies as a direct substitute for the IMS05EB181K based on electrical and mechanical parameter equivalence. The Bourns component carries active product status and meets ROHS3 compliance and REACH unaffected designation, supporting long-term supply chain reliability. Both components share identical inductance, current rating, and DC resistance specifications within the same through-hole axial package format. Selection between these parts may be determined by availability, lead time, packaging quantity requirements, or existing supplier relationships, as electrical performance characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-184-RC replace the IMS05EB181K in existing designs?

A: Yes. Both components meet identical electrical specifications for inductance (180 µH), current rating (135 mA), and DC resistance (4.4Ohm Max). Both are shielded molded inductors in through-hole axial packages, confirming mechanical and electrical compatibility.

Q: Are there differences in physical dimensions between these parts?

A: The 9250A-184-RC is specified at 0.162" diameter by 0.410" length (4.11mm x 10.41mm). Dimension data for the IMS05EB181K is not provided in the reference specifications. Verify PCB layout compatibility if space constraints are critical.

Q: What compliance certifications apply to the substitute part?

A: The 9250A-184-RC is ROHS3 compliant and REACH unaffected, supporting regulatory requirements for electronics manufacturing and distribution in restricted substance environments.

Q: How do saturation current specifications affect substitution?

A: The 9250A-184-RC specifies saturation current (Isat) at 85mA. This parameter indicates the current level at which inductance begins to degrade. Verify that circuit operating conditions remain below this threshold to maintain specified inductance performance.

Q: What is the significance of the self-resonant frequency specification?

A: The 9250A-184-RC self-resonant frequency is specified at 8MHz. This parameter defines the frequency above which the component exhibits capacitive rather than inductive behavior. Confirm that circuit operating frequencies remain below this limit for intended inductive performance.
