Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24151C is determined by the following critical parameters:

• Inductance Value: 150 µH (exact match required)
• Current Rating: 400 mA minimum
• DC Resistance: 1.1Ohm maximum
• Shielding Configuration: Unshielded
• Mounting Technology: Surface Mount
• Operating Temperature Range: Must support -40°C minimum and 85°C maximum
• Regulatory Compliance: ROHS3 Compliant

The SDR0604-151KL from Bourns Inc. meets all substitution criteria. Both components share identical inductance, current rating, and DC resistance specifications. The substitute part maintains unshielded construction and surface mount packaging compatibility. Operating temperature range of the substitute (-40°C ~ 125°C) encompasses the primary part's range.

Parameter Comparison

Engineering Selection Recommendations

Both the 24151C and SDR0604-151KL are Active status products with full ROHS3 compliance and REACH Unaffected designation. Selection between these components is based on availability and supply chain requirements. The SDR0604-151KL provides an extended operating temperature ceiling of 125°C compared to the 24151C's 85°C maximum, offering additional thermal margin in applications where ambient conditions approach the upper specification limit. Both components carry MSL Level 1 (Unlimited) moisture sensitivity classification, indicating equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the SDR0604-151KL replace the 24151C in existing designs?

A: Yes. Both components share identical inductance (150 µH), current rating (400 mA), and DC resistance (1.1Ohm Max) specifications. Surface mount packaging and unshielded construction are equivalent. Operating temperature range compatibility is confirmed within the 24151C's specified -40°C to 85°C window.

Q: What are the physical dimension differences between these parts?

A: The 24151C measures 0.228" L x 0.205" W x 0.177" H (5.80mm x 5.20mm x 4.50mm). The SDR0604-151KL measures 0.228" L x 0.228" W x 0.189" H (5.80mm x 5.80mm x 4.80mm). Width and height variations are minor and do not affect PCB layout compatibility for standard surface mount applications.

Q: Are there differences in core material construction?

A: The 24151C uses wirewound construction with unspecified core material. The SDR0604-151KL uses drum core ferrite wirewound construction. Both achieve identical electrical specifications at the specified test frequency of 1 kHz.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are ROHS3 Compliant, REACH Unaffected, and carry EAR99 ECCN classification with identical HTSUS code 8504.50.4000.

Q: What is the saturation current difference?

A: The 24151C saturation current is not specified. The SDR0604-151KL specifies 540mA saturation current, which exceeds the 400mA rated current of both components.
