Murata 482R2SC Equivalent & Substitute Parts

Part Overview

The Murata 482R2SC is a 2.2 µH shielded wirewound inductor rated for 8.2 A continuous current with a maximum DC resistance of 10mOhm. This surface mount component is designed for applications requiring low-inductance, high-current filtering and energy storage in compact form factors. The part is Active status and ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Murata 482R2SC is permissible when the alternative component meets the following criteria:

Inductance value of 2.2 µH within the ±30% tolerance band (1.54 µH to 2.86 µH)

Current rating of 8.2 A or greater

DC resistance not exceeding 10.5 mOhm (allowing minimal variance from the 10 mOhm specification)

Shielded construction to maintain electromagnetic isolation

Surface mount configuration with compatible lead count and footprint dimensions

Operating temperature range encompassing -40°C to 85°C minimum

ROHS3 compliance and equivalent regulatory certifications

The Bourns SRR1260-2R2Y meets these substitution criteria through equivalent electrical specifications and compatible mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 482R2SC and Bourns SRR1260-2R2Y are Active status components with ROHS3 compliance and REACH unaffected certifications. The Bourns substitute provides an extended operating temperature range (-40°C to 125°C versus -40°C to 85°C), which offers additional thermal margin in applications approaching the upper temperature limit. The DC resistance variance of 0.5 mOhm is negligible for most power delivery applications. Both components carry unlimited moisture sensitivity classification, eliminating special handling requirements. Selection between these parts should be based on availability, lead time, and specific thermal operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SRR1260-2R2Y be used as a direct replacement for the Murata 482R2SC?

A: Yes. Both components share identical inductance (2.2 µH), current rating (8.2 A), tolerance (±30%), shielding, and mounting type. The DC resistance difference of 0.5 mOhm is within acceptable engineering variance for most applications.

Q: What is the significance of the extended temperature range in the Bourns part?

A: The Bourns SRR1260-2R2Y operates to 125°C versus 85°C for the Murata part. This provides additional thermal headroom in applications where ambient or self-heating conditions approach the upper operating limit.

Q: Are there mechanical footprint differences between these parts?

A: Both components are nonstandard, 4-lead surface mount inductors with similar dimensions. The Murata measures 12.20mm × 12.20mm × 6.00mm (max height), while the Bourns measures 12.50mm × 12.50mm × 6.50mm (max height). PCB layout verification is recommended to confirm clearance compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the Murata 482R2SC and Bourns SRR1260-2R2Y are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes.

Q: What is the difference between wirewound and drum core construction?

A: The Murata 482R2SC uses wirewound construction, while the Bourns SRR1260-2R2Y uses drum core wirewound construction with ferrite material. Both achieve equivalent electrical performance at the specified inductance and current ratings.
