Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 24120C is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 12 µH (exact match required)
• Current rating: minimum 1.36 A
• DC resistance: maximum 100mOhm
• Mounting type: Surface Mount
• Shielding configuration: Unshielded

Secondary Compatibility Factors:

• Operating temperature range: minimum -40°C ~ 85°C coverage
• Package footprint: compatible nonstandard dimensions
• Self resonant frequency: 22 MHz or higher
• RoHS3 compliance status

The Bourns SDR0604-120ML meets all primary matching criteria with equivalent inductance, higher current rating (1.4 A), and compatible DC resistance specification (120mOhm Max). Both components share identical mounting technology, shielding type, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 24120C and Bourns SDR0604-120ML are active products with full RoHS3 compliance and REACH unaffected status, making either suitable for regulated applications. The Bourns SDR0604-120ML provides extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C) and higher current saturation rating (1.9A), offering additional thermal and performance margin in demanding applications. The Murata 24120C maintains lower DC resistance (100mOhm Max) and higher self resonant frequency (26 MHz), which may be advantageous in high-frequency or low-loss circuit designs. Footprint compatibility requires verification due to minor dimensional differences in width (5.20mm versus 5.80mm) and height (4.50mm versus 4.80mm).

Frequently Asked Questions (FAQ)

Q: Can the Bourns SDR0604-120ML directly replace the Murata 24120C?

A: Direct replacement is possible from an electrical standpoint. Both components share identical 12 µH inductance, unshielded configuration, and surface mount technology. However, PCB layout verification is required due to footprint differences: the Bourns part is 0.228" x 0.228" (5.80mm x 5.80mm) versus the Murata part at 0.228" x 0.205" (5.80mm x 5.20mm), with height differences of 4.80mm versus 4.50mm respectively.

Q: What are the key electrical differences between these parts?

A: The Bourns SDR0604-120ML has a slightly higher maximum DC resistance (120mOhm versus 100mOhm) and lower self resonant frequency (22 MHz versus 26 MHz). The Bourns part offers higher current rating (1.4 A versus 1.36 A) and extended temperature range (-40°C ~ 125°C versus -40°C ~ 85°C).

Q: Are both parts suitable for high-frequency applications?

A: Both components operate at frequencies suitable for most power conversion applications. The Murata 24120C has a higher self resonant frequency (26 MHz), which may provide better performance in circuits operating near or above 20 MHz. The Bourns SDR0604-120ML at 22 MHz remains suitable for standard switching power supply frequencies.

Q: What compliance certifications apply to both parts?

A: Both the Murata 24120C and Bourns SDR0604-120ML are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry HTSUS code 8504.50.4000 and maintain Moisture Sensitivity Level 1 (Unlimited).

Q: How do the core materials differ?

A: The Murata 24120C uses a standard wirewound construction, while the Bourns SDR0604-120ML employs a drum core ferrite wirewound design. This construction difference contributes to the Bourns part's extended temperature rating and higher saturation current.
