Parameter Comparison

Engineering Selection Recommendations

The 9250A-334-RC qualifies as a direct substitute for the IMS05ER331K based on matching electrical specifications: identical inductance (330 µH), current rating (110 mA), and maximum DC resistance (6.4Ohm). Both components feature shielded molded construction in through-hole axial packages, ensuring mechanical and electrical compatibility.

The Bourns 9250A-334-RC carries active product status with ROHS3 compliance and REACH unaffected certification, confirming regulatory alignment for current manufacturing and deployment. The component is available in higher inventory volume (2270 pieces) compared to the Vishay Dale part, providing supply chain flexibility.

Selection between these parts should be based on availability, lead time, and procurement cost, as electrical performance and mechanical fit are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-334-RC replace the IMS05ER331K in existing designs?

A: Yes. Both inductors share identical inductance (330 µH), current rating (110 mA), and DC resistance (6.4Ohm Max). The through-hole axial package and shielded molded construction are identical, enabling direct board-level substitution without circuit modification.

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

A: The 9250A-334-RC is specified at 0.162" diameter by 0.410" length (4.11mm x 10.41mm). The IMS05ER331K dimensions are not provided in the available data. Verify board layout compatibility if space constraints are critical.

Q: What is the inductance tolerance for each part?

A: The 9250A-334-RC specifies ±10% tolerance. The IMS05ER331K tolerance is not provided in available documentation. If tolerance specifications are required for circuit performance, consult the Vishay Dale datasheet.

Q: Are both parts compliant with current regulatory standards?

A: The 9250A-334-RC is ROHS3 compliant and REACH unaffected. Regulatory status for the IMS05ER331K is not specified in available data. Confirm compliance requirements with your procurement or quality department.

Q: What is the saturation current for these inductors?

A: The 9250A-334-RC specifies saturation current (Isat) at 65 mA. The IMS05ER331K saturation current is not provided. For applications operating near maximum current ratings, consult detailed datasheets.
