23S330C Equivalent & Substitute Parts

Part Overview

The 23S330C is a 33 µH shielded wirewound inductor manufactured by Murata Power Solutions Inc., rated for 650 mA continuous current with a maximum DC resistance of 241mOhm. This surface mount component operates across the temperature range of -40°C to 85°C and is classified as Active product status with full RoHS3 compliance. Substitute parts are identified when equivalent inductance values, current ratings, and shielding characteristics align within acceptable electrical and mechanical tolerances for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 23S330C is determined by the following critical parameters:

• Inductance Value: Must be 33 µH to maintain circuit performance
• Current Rating: Substitute must support minimum 650 mA; lower ratings are not acceptable
• DC Resistance: Must not exceed 241mOhm to preserve power efficiency characteristics
• Shielding: Must be shielded to maintain electromagnetic compatibility
• Mounting Type: Must be surface mount compatible
• RoHS Compliance: Must meet ROHS3 requirements for regulatory alignment

The SRR6603-330ML from Bourns Inc. qualifies as a substitute based on matching inductance (33 µH), shielded construction, surface mount configuration, and RoHS3 compliance. However, the current rating differential (600 mA vs. 650 mA) and DC resistance improvement (190mOhm vs. 241mOhm) must be evaluated within specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 23S330C and SRR6603-330ML maintain Active product status and full RoHS3 compliance. The SRR6603-330ML offers superior DC resistance performance (190mOhm vs. 241mOhm), which reduces power dissipation. The extended operating temperature range of the Bourns component (-55°C ~ 125°C vs. -40°C ~ 85°C) provides additional thermal margin. The primary consideration is the current rating differential: the SRR6603-330ML is rated for 600 mA versus the 23S330C's 650 mA. Selection between these components depends on whether the application circuit operates at or near the 650 mA threshold. Both components are packaged in Tape & Reel format and maintain shielded construction suitable for noise-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the SRR6603-330ML replace the 23S330C in all applications?

A: Substitution is valid when circuit current requirements do not exceed 600 mA. The SRR6603-330ML's lower current rating (600 mA vs. 650 mA) must be verified against actual application load conditions. Both components share identical inductance values and shielding characteristics.

Q: What is the significance of the DC resistance difference?

A: The SRR6603-330ML exhibits lower DC resistance (190mOhm vs. 241mOhm), resulting in reduced power dissipation and improved efficiency. This represents a performance advantage in power-sensitive applications.

Q: Are there physical compatibility concerns?

A: Both components are surface mount with nonstandard packages. The SRR6603-330ML is slightly larger in length (6.60mm vs. 6.20mm) and narrower in width (4.40mm vs. 5.60mm), with a lower profile (3.00mm vs. 3.20mm). PCB layout verification is required to confirm mechanical fit.

Q: Do both parts meet regulatory requirements?

A: Both the 23S330C and SRR6603-330ML are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8504.50.4000).

Q: What is the inductance tolerance specification?

A: The 23S330C tolerance is not specified in the provided data. The SRR6603-330ML carries ±20% tolerance. Tolerance matching should be verified against circuit design requirements.
