Key Parameters

Substitute Part Grouping Explanation

Substitution of the LHLP10NB471KB is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 470 µH
• Inductance tolerance: ±10%
• DC resistance: 1.3 Ohm maximum
• Shielding: Shielded configuration
• Core material: Ferrite
• Mounting type: Through hole
• Package configuration: Radial, vertical cylinder

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 460 mA
• Operating temperature range: Substitute must support the application's thermal requirements
• Physical dimensions: Substitute must fit within the mechanical constraints of the target application

The Würth Elektronik 744731471 meets all critical matching parameters and provides enhanced current handling capability (600 mA versus 460 mA), making it a valid substitute for applications where the original component is no longer available.

Engineering Selection Recommendations

LHLP10NB471KB (Taiyo Yuden): This component is classified as obsolete and is not recommended for new designs. However, it remains suitable for maintenance and repair of existing systems where original component specifications are required. The part is ROHS3 compliant and carries EAR99 classification.

744731471 (Würth Elektronik): This substitute component is classified as active and is the recommended selection for applications requiring a 470 µH shielded inductor with through-hole mounting. The 744731471 provides electrical equivalence to the LHLP10NB471KB while offering enhanced current handling (600 mA versus 460 mA) and an extended operating temperature range (-40°C ~ 125°C versus -25°C ~ 105°C). Both components are ROHS3 compliant and carry EAR99 classification. The substitute is suitable for direct replacement in existing designs and for new applications.

Physical dimensions differ between the two components. The 744731471 features a smaller footprint (0.307" diameter, 0.295" height) compared to the LHLP10NB471KB (0.433" diameter, 0.433" height). Verification of mechanical fit within the target application is required before implementation.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744731471 be used as a direct replacement for the Taiyo Yuden LHLP10NB471KB?

A: The 744731471 is electrically equivalent to the LHLP10NB471KB in terms of inductance value, tolerance, DC resistance, and shielding. Both components are ferrite-core, through-hole mounted, radial vertical cylinders with ROHS3 compliance. However, the 744731471 has a smaller physical footprint. Direct replacement is possible only if the smaller dimensions fit within the mechanical constraints of the target application.

Q: What are the key differences between these two inductors?

A: The primary differences are: (1) Current rating—744731471 supports 600 mA versus 460 mA for the LHLP10NB471KB; (2) Operating temperature range—744731471 operates from -40°C to 125°C versus -25°C to 105°C for the LHLP10NB471KB; (3) Physical dimensions—744731471 is smaller; (4) Product status—LHLP10NB471KB is obsolete while 744731471 is active; (5) Manufacturer—Taiyo Yuden versus Würth Elektronik.

Q: Are there any compliance or certification concerns when substituting the 744731471 for the LHLP10NB471KB?

A: Both components are ROHS3 compliant and carry EAR99 classification. No compliance barriers exist for substitution. The 744731471 carries additional REACH Unaffected status.

Q: What should be verified before implementing the 744731471 as a substitute?

A: Mechanical fit must be verified. The 744731471 has a diameter of 0.307" (7.80 mm) and height of 0.295" (7.50 mm), compared to the LHLP10NB471KB dimensions of 0.433" (11.00 mm) diameter and 0.433" (11.00 mm) height. Confirm that the smaller footprint accommodates the target application's PCB layout and component spacing requirements.

Q: Is the higher current rating of the 744731471 a concern for applications designed for the LHLP10NB471KB?

A: No. The 744731471's higher current rating (600 mA) provides additional design margin and does not create compatibility issues. Applications operating at or below 460 mA will function correctly with the substitute component.

Q: Can the LHLP10NB471KB be sourced for new designs?

A: The LHLP10NB471KB is classified as obsolete. New designs should specify the Würth Elektronik 744731471 or equivalent active components. The LHLP10NB471KB may be available from inventory sources for maintenance and repair applications only.
