26S150C Equivalent & Substitute Parts

Part Overview

The 26S150C is a 15 µH shielded wirewound inductor manufactured by Murata Power Solutions Inc., rated for 2.45 A continuous current with a maximum DC resistance of 60mOhm. 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 application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 26S150C is determined by the following critical parameters:

• Inductance Value: Must be 15 µH to maintain circuit performance
• Shielding Type: Must be shielded to preserve electromagnetic isolation
• Mounting Configuration: Must be surface mount compatible
• Current Rating: Must meet or exceed 2.45 A to handle application load
• DC Resistance: Lower or equal DCR values are acceptable; higher values may increase power dissipation
• Operating Temperature Range: Must support minimum -40°C to 85°C operation
• Compliance: RoHS3 compliance required for regulatory alignment

The SRR1240-150M from Bourns Inc. qualifies as a substitute based on matching inductance (15 µH), shielded construction, surface mount packaging, and superior current rating (4.6 A), with acceptable DC resistance (47mOhm Max) and extended temperature range support.

Parameter Comparison

Engineering Selection Recommendations

Both the 26S150C and SRR1240-150M maintain Active product status and full RoHS3 compliance. The SRR1240-150M provides performance advantages including higher current rating (4.6 A versus 2.45 A), lower DC resistance (47mOhm versus 60mOhm), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). Physical dimensions differ between the two components; the 26S150C measures 0.496" L x 0.181" W x 0.232" H, while the SRR1240-150M measures 0.492" L x 0.492" W x 0.177" H. Both components carry ECCN EAR99 classification and identical HTSUS coding, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SRR1240-150M directly replace the 26S150C in all applications?

A: Substitution is valid when the application requires 15 µH inductance with shielded construction and surface mount packaging. The SRR1240-150M's higher current rating and lower DC resistance provide operational margin. Physical footprint differences must be verified against PCB layout constraints, as the SRR1240-150M has a larger lateral dimension (0.492" x 0.492" versus 0.496" x 0.181").

Q: What are the key electrical differences between these parts?

A: The SRR1240-150M offers superior electrical performance with 4.6 A current rating (versus 2.45 A), 47mOhm maximum DCR (versus 60mOhm), and higher self-resonant frequency (22 MHz versus 19.7 MHz). Both maintain identical 15 µH inductance and shielded characteristics.

Q: Are there temperature range considerations for substitution?

A: The SRR1240-150M supports -40°C to 125°C operation, exceeding the 26S150C's -40°C to 85°C range. Applications operating within the 26S150C's original temperature specification remain fully compatible with the substitute.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both components are RoHS3 compliant, REACH unaffected, carry MSL 1 (Unlimited) moisture sensitivity rating, and share identical ECCN and HTSUS classifications.

Q: What should be evaluated before implementing the SRR1240-150M as a substitute?

A: Verify PCB layout accommodation for the larger footprint (0.492" x 0.492" versus 0.496" x 0.181"), confirm that the lower DCR does not introduce unintended circuit behavior, and validate that the higher self-resonant frequency aligns with application frequency response requirements.
