Würth Elektronik 744053002 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 744053002 is a 2.6 µH shielded drum core wirewound inductor rated for 3 A continuous current with a maximum DC resistance of 30 mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is housed in a 2323 (5858 Metric) package. The part is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same inductance value, current rating, and package dimensions.

Substitute Part Grouping Explanation

The Bourns Inc. SRR5028-2R6Y qualifies as a direct substitute for the Würth Elektronik 744053002 based on the following critical parameters:

Electrical equivalence is established through matching inductance value (2.6 µH), inductance tolerance (±30%), current rating (3 A), saturation current (2.7 A), and maximum DC resistance (30 mOhm). Both components utilize ferrite core material with shielding and operate across the identical temperature range (-40°C to 125°C).

Mechanical compatibility is confirmed through identical footprint dimensions (0.228" L x 0.228" W / 5.80 mm x 5.80 mm) and seated height (0.118" / 3.00 mm), enabling direct board-level replacement. Both components are surface mount devices packaged in tape and reel format.

Compliance alignment includes ROHS3 certification and MSL 1 rating for both parts, ensuring regulatory and environmental compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Würth Elektronik 744053002 and Bourns SRR5028-2R6Y maintain active production status with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these components may be based on availability, lead time, or supply chain requirements, as electrical and mechanical specifications are equivalent. Both parts satisfy the same regulatory and environmental compliance frameworks for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the Bourns SRR5028-2R6Y be used as a direct replacement for the Würth Elektronik 744053002?

A: Yes. Both components share identical inductance (2.6 µH), current rating (3 A), DC resistance (30 mOhm max), core material (ferrite), shielding, package dimensions (2323 / 5858 Metric), and operating temperature range (-40°C to 125°C). Board-level substitution is mechanically and electrically compatible.

Q: Are there differences in self-resonant frequency between these parts?

A: The Würth Elektronik 744053002 has a self-resonant frequency of 55 MHz, while the Bourns SRR5028-2R6Y operates at 77 MHz. This difference does not affect substitution eligibility for applications within the specified inductance and current parameters.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. Both carry EAR99 ECCN classification and are REACH unaffected.

Q: What is the package compatibility between these inductors?

A: Both parts use identical surface mount package dimensions of 0.228" L x 0.228" W (5.80 mm x 5.80 mm) with a maximum seated height of 0.118" (3.00 mm). Both are supplied in tape and reel packaging for automated assembly.

Q: Are there any performance differences in Q factor?

A: The Bourns SRR5028-2R6Y specifies Q of 7 at 7.96 MHz. The Würth Elektronik 744053002 does not provide Q factor specification. This parameter difference does not affect substitution for applications requiring the specified inductance and current ratings.
