48330SC Equivalent & Substitute Parts

Part Overview

The Murata Power Solutions 48330SC is a 33 µH shielded wirewound inductor rated for 2.8 A continuous current with a maximum DC resistance of 73 mOhm. This surface mount component operates across the -40°C to 85°C temperature range and is designed for applications requiring fixed inductance in compact form factors. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Substitute Part Grouping Explanation

The Bourns SRR1260-330M qualifies as a direct substitute based on the following alignment of critical parameters:

Inductance value matches at 33 µH with identical ±20% tolerance. Both parts are shielded surface mount inductors designed for similar circuit applications. The SRR1260-330M provides a higher current rating of 3 A compared to the 48330SC's 2.8 A, ensuring compatibility in applications operating at or below the original part's current specification. DC resistance of 60 mOhm on the substitute is lower than the 73 mOhm maximum of the main part, resulting in reduced power dissipation. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Operating temperature range of the substitute extends to 125°C, exceeding the main part's 85°C upper limit.

Engineering Selection Recommendations

Both the 48330SC and SRR1260-330M maintain active product status with full ROHS3 compliance and REACH unaffected designation. The SRR1260-330M is suitable for direct substitution in applications where the 48330SC is specified, provided that physical package dimensions are verified for PCB layout compatibility. The substitute part's improved current rating and extended temperature range present no compatibility constraints for circuits designed around the original part's specifications. Selection between these parts should be based on availability, packaging format preference (Tape & Reel versus Cut Tape & Digi-Reel), and supplier lead times.

Frequently Asked Questions (FAQ)

Q: Can the SRR1260-330M replace the 48330SC in all applications? A: Yes, provided PCB layout accommodates the substitute's physical dimensions. The SRR1260-330M's higher current rating and lower DC resistance make it functionally compatible with circuits designed for the 48330SC.

Q: What are the physical dimension differences between these parts? A: The 48330SC measures 0.480" × 0.480" × 0.236" (12.20mm × 12.20mm × 6.00mm). The SRR1260-330M measures 0.492" × 0.492" × 0.256" (12.50mm × 12.50mm × 6.50mm). Verify PCB footprint clearance before substitution.

Q: Are there differences in packaging that affect handling or assembly? A: The 48330SC is supplied in Tape & Reel format, while the SRR1260-330M is available in Cut Tape & Digi-Reel format. Both are surface mount components with identical moisture sensitivity levels and require standard SMD assembly processes.

Q: Does the lower DC resistance of the SRR1260-330M affect circuit performance? A: Lower DC resistance (60 mOhm versus 73 mOhm) reduces power dissipation and heat generation, which is beneficial for thermal management. No negative circuit effects result from this parameter difference.

Q: What compliance certifications apply to both parts? A: Both the 48330SC and SRR1260-330M are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8504.50.4000.
