Würth Elektronik 744030004 Equivalent & Substitute Parts

Part Overview

The Würth Elektronik 744030004 is a 4.7 µH shielded drum core wirewound inductor rated for 480 mA continuous current with a maximum DC resistance of 290mOhm. This surface mount component operates across the temperature range of -40°C to 125°C and is designed for applications requiring compact, shielded inductive filtering in power conversion and signal conditioning circuits. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent inductance values, compatible current ratings, matching core material, and identical mounting technology are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Engineering Selection Recommendations

Both the Würth Elektronik 744030004 and Sumida CDRH2D11NP-4R7NC are active production components with ROHS3 compliance and MSL 1 rating, qualifying them for equivalent functional use in surface mount applications requiring 4.7 µH shielded ferrite inductors.

The Sumida substitute provides enhanced electrical performance with 880 mA current rating versus 480 mA, and reduced DC resistance of 170mOhm compared to 290mOhm. Selection between these parts depends on circuit current requirements and thermal dissipation constraints.

The Würth part supports operation to 125°C maximum, while the Sumida part is rated to 100°C maximum. Applications requiring the full 125°C operating range must use the Würth component.

Both parts are supplied in Tape & Reel packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between the Würth 744030004 and Sumida CDRH2D11NP-4R7NC?

A: Compatibility is established through matching inductance value (4.7 µH), identical tolerance (±30%), ferrite core material, shielded configuration, surface mount technology, and identical inductance test frequency (100 kHz). Both parts meet ROHS3 compliance and MSL 1 requirements.

Q: Can the Sumida CDRH2D11NP-4R7NC be used in all applications designed for the Würth 744030004?

A: The Sumida part is suitable for applications operating at or below 100°C. Applications requiring operation to 125°C must use the Würth component. The Sumida part's higher current rating (880 mA) and lower DC resistance (170mOhm) make it suitable for circuits designed for the Würth part's 480 mA rating.

Q: Are there physical size differences between these parts?

A: Yes. The Würth 744030004 measures 4.60mm L × 3.30mm W × 1.05mm H (seated). The Sumida CDRH2D11NP-4R7NC measures 3.00mm L × 3.00mm W × 1.10mm H (seated). PCB layout and component placement must accommodate these dimensional differences.

Q: Do both parts use the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging suitable for automated pick-and-place assembly.

Q: What is the saturation current for both parts?

A: Both the Würth 744030004 and Sumida CDRH2D11NP-4R7NC have identical saturation current (Isat) ratings of 500 mA.
