Murata Power Solutions 23680C Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 23680C is a 68 µH unshielded wirewound surface mount inductor rated for 490 mA continuous current with a maximum DC resistance of 1.051Ohm. This component is part of the 2300 series and is classified as Active product status. The part is packaged in Tape & Reel format with nonstandard dimensions of 4.50mm x 4.00mm x 3.20mm (max height). Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific application parameters within acceptable tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 23680C is determined by the following critical parameters:

• Inductance Value: Must be 68 µH to maintain circuit functionality
• Current Rating: Substitute must support minimum 490 mA continuous current
• DC Resistance: Must not exceed 1.051Ohm to ensure acceptable power dissipation and circuit performance
• Mounting Type: Must be Surface Mount compatible
• Package Dimensions: Physical footprint must be compatible with 4.50mm x 4.00mm x 3.20mm (max) envelope
• Shielding Configuration: Unshielded topology must be maintained
• Compliance: RoHS3 compliance and MSL Level 1 required

The Bourns SDR0403-680KL meets these substitution criteria with equivalent inductance, compatible current rating (460 mA), acceptable DC resistance (1.12Ohm Max), matching surface mount configuration, and identical physical footprint dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 23680C and Bourns SDR0403-680KL are Active status components with full RoHS3 compliance and MSL Level 1 rating, confirming suitability for production applications. The Bourns substitute provides an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), which offers additional thermal margin in applications requiring elevated temperature performance. The SDR0403-680KL exhibits slightly higher DC resistance (1.12Ohm Max) and lower current rating (460 mA) compared to the primary part; these differences remain within acceptable substitution parameters for circuits designed to the 23680C specification. Physical compatibility is confirmed through identical footprint dimensions (4.50mm x 4.00mm), with a maximum height variance of 0.30mm (4.60mm versus 3.20mm) that must be evaluated against specific PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SDR0403-680KL be used as a direct replacement for the Murata 23680C?

A: The Bourns SDR0403-680KL qualifies as a substitute part based on matching inductance value (68 µH), compatible current rating (460 mA minimum versus 490 mA requirement), acceptable DC resistance (1.12Ohm Max versus 1.051Ohm Max), and identical surface mount footprint. The 0.30mm height difference must be verified against PCB assembly clearance requirements.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution is determined by inductance value (68 µH), current rating capability (minimum 490 mA), DC resistance (maximum 1.051Ohm), unshielded configuration, surface mount mounting type, and physical footprint compatibility (4.50mm x 4.00mm x 3.20mm max).

Q: Does the higher DC resistance of the Bourns part affect circuit performance?

A: The Bourns SDR0403-680KL exhibits 0.069Ohm higher maximum DC resistance (1.12Ohm versus 1.051Ohm). This difference results in increased power dissipation and must be evaluated within the specific application's thermal and current budget constraints.

Q: Are both parts compliant with industry standards?

A: Both components are ROHS3 compliant, carry MSL Level 1 rating (Unlimited moisture sensitivity), and maintain Active product status, confirming suitability for current production applications.

Q: What is the impact of the height difference between these parts?

A: The Bourns part has a maximum seated height of 4.60mm compared to 3.20mm for the Murata part, representing a 0.30mm increase. This variance must be assessed against PCB assembly specifications, component clearance requirements, and any height-constrained applications.
