Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMS05ST3R3J are qualified based on the following critical parameters that must match or exceed the original specification:

• Inductance Value: 3.3 µH (exact match required)
• Current Rating: 480 mA minimum
• DC Resistance: 350 mOhm maximum
• Shielding Type: Shielded construction
• Core Material: Ferrite
• Mounting Configuration: Through-hole axial package
• Operating Temperature Range: -55°C to 125°C minimum

The 9250A-332-RC from Bourns Inc. meets all these criteria and is classified as a direct equivalent substitute. Both components share identical electrical performance characteristics and mechanical compatibility for board-level integration.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-332-RC qualifies as a direct substitute for the IMS05ST3R3J based on matching electrical specifications across all critical parameters: inductance value, current rating, and DC resistance. The Bourns component carries Active product status and maintains full compliance with ROHS3 and REACH regulations, ensuring long-term availability and regulatory alignment. Both components are shielded ferrite-core inductors in through-hole axial configuration, suitable for identical circuit applications. Selection between these parts may be determined by inventory availability, lead time, or established supplier relationships, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 9250A-332-RC be used as a direct replacement for the IMS05ST3R3J?

A: Yes. Both components share identical inductance (3.3 µH), current rating (480 mA), and DC resistance (350 mOhm Max) specifications. The shielded ferrite-core construction and through-hole axial package are identical, making them electrically and mechanically interchangeable.

Q: Are there any physical dimension differences between these parts?

A: The 9250A-332-RC is specified at 0.162" diameter by 0.410" length (4.11mm x 10.41mm). Physical dimensions for the IMS05ST3R3J are not provided in the available data. Verify board layout compatibility if space constraints are critical.

Q: What compliance certifications apply to the substitute part?

A: The 9250A-332-RC is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Does inductance tolerance affect substitution suitability?

A: The 9250A-332-RC carries a ±10% inductance tolerance. If the original design requires tighter tolerance specifications, confirm that the ±10% tolerance band is acceptable for circuit performance before substitution.

Q: What is the operating temperature range for these inductors?

A: The 9250A-332-RC operates across -55°C to 125°C. This range is standard for industrial and commercial applications. Confirm this range meets your specific application requirements.
