Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IMS05ER151K are qualified based on the following electrical and mechanical parameters:

• Inductance Value: 150 µH (exact match required)
• Current Rating: 140 mA (minimum threshold)
• DC Resistance: 4.1 Ohm maximum (electrical performance criterion)
• Shielding Type: Shielded (electromagnetic containment requirement)
• Mounting Configuration: Through Hole, Axial package (mechanical compatibility)
• Operating Temperature Range: -55°C to 125°C (environmental specification)

The 9250A-154-RC from Bourns Inc. meets all specified parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The 9250A-154-RC qualifies as a direct substitute for the IMS05ER151K based on matching electrical specifications (inductance, current rating, and DC resistance) and identical mechanical configuration (through-hole axial package). The Bourns component carries ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for modern applications. Selection between these parts may be determined by availability, packaging format (Bulk for 9250A-154-RC), or supply chain considerations.

Frequently Asked Questions (FAQ)

Q: What makes the 9250A-154-RC a valid substitute for the IMS05ER151K?

A: Both components share identical inductance (150 µH), current rating (140 mA), DC resistance (4.1 Ohm maximum), shielding type (shielded), and mechanical package (through-hole axial). These parameters define functional equivalence for inductor substitution.

Q: Are there any differences in performance between these parts?

A: The 9250A-154-RC provides additional documented specifications including inductance tolerance (±10%), saturation current (90 mA), quality factor (55 @ 790 kHz), and self-resonant frequency (8.5 MHz). These parameters do not affect substitutability but may be relevant for detailed circuit analysis.

Q: Can the 9250A-154-RC be used in all applications where the IMS05ER151K is specified?

A: Yes, provided the application operates within the specified electrical and temperature parameters. Both components are rated for -55°C to 125°C operation and support 140 mA maximum current.

Q: What packaging differences exist between these parts?

A: The IMS05ER151K is available in standard packaging, while the 9250A-154-RC is supplied in Bulk packaging. Both use identical through-hole axial mechanical configuration suitable for PCB assembly.

Q: Are there regulatory compliance considerations?

A: The 9250A-154-RC is ROHS3 compliant and REACH unaffected. Regulatory status for the IMS05ER151K was not provided in the reference data.
