Key Parameters

Substitute Part Grouping Explanation

Substitution of the Murata 24680C is determined by the following critical parameters:

• Inductance Value: 68 µH (exact match required)
• Current Rating: Minimum 610 mA continuous current capability
• DC Resistance: Maximum 460mOhm to 520mOhm acceptable range
• Mounting Type: Surface mount configuration
• Shielding: Unshielded construction
• Package Compatibility: Nonstandard form factor with physical dimensions within tolerance

The Bourns SDR0604-680KL meets these substitution criteria with equivalent inductance, higher current saturation capability, and compatible physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The Bourns SDR0604-680KL qualifies as a direct substitute for the Murata 24680C based on matching inductance value, equivalent current rating capability, and compatible surface mount package configuration. Both components maintain ROHS3 compliance and REACH unaffected status. The Bourns part provides extended operating temperature range to 125°C and higher saturation current specification, offering design margin in thermal and current stress conditions. Physical dimensions show minor variation in width and height; PCB layout verification is required to confirm mechanical fit within the application envelope.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SDR0604-680KL directly replace the Murata 24680C in existing designs?

A: Direct replacement is possible when the application accommodates the physical dimension differences. The Bourns part is 0.60mm wider and 0.30mm taller. Verify PCB footprint and clearance requirements before implementation.

Q: What is the significance of the higher saturation current in the Bourns part?

A: The Bourns SDR0604-680KL specifies 840 mA saturation current compared to the unspecified saturation rating of the Murata part. This parameter indicates the current level at which inductance begins to degrade. Higher saturation current provides additional design margin for transient current conditions.

Q: Are there temperature range considerations for substitution?

A: The Murata 24680C operates to 85°C maximum, while the Bourns SDR0604-680KL extends to 125°C. Applications operating near the upper temperature limit of the Murata part may benefit from the Bourns substitute. Verify thermal performance requirements for your specific circuit.

Q: How do the DC resistance values compare?

A: The Murata part specifies 460mOhm maximum DCR, while the Bourns part specifies 520mOhm maximum. The 60mOhm difference represents approximately 13% higher resistance in the Bourns component. For power dissipation-sensitive applications, calculate I²R losses to confirm acceptability.

Q: What packaging considerations apply to these inductors?

A: Both components are supplied in Tape & Reel (TR) packaging for automated assembly. Nonstandard package dimensions require verification against your pick-and-place equipment specifications and PCB design files.
