Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LHLP10TB331KB are identified based on strict alignment with the following critical parameters:

Primary Matching Criteria:

• Inductance value: 330 µH (exact match required)
• Core material: Ferrite (shielded construction)
• Mounting type: Through hole
• Package configuration: Radial, vertical cylinder
• Shielding: Shielded design

Secondary Compatibility Factors:

• Current rating: Substitute must equal or exceed 580 mA
• DC resistance: Substitute must not exceed 880mOhm maximum
• Physical dimensions: Compatible with 0.433" (11.00mm) diameter footprint
• Environmental compliance: ROHS3 compliance maintained

The substitute part 7447471331 (Würth Elektronik WE-TIS series) satisfies all primary matching criteria and provides enhanced performance characteristics in current handling and operating temperature range, while maintaining ferrite core shielded construction and through-hole radial mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The 7447471331 (Würth Elektronik WE-TIS series) is a qualified substitute for the obsolete LHLP10TB331KB based on the following engineering factors:

Functional Equivalence: Both components maintain identical inductance values (330 µH) with ferrite core shielded construction and through-hole radial mounting. Physical footprint compatibility is confirmed through matching diameter specifications (11.00mm).

Performance Enhancement: The substitute part provides superior electrical performance with reduced DC resistance (480 mOhm versus 880 mOhm maximum) and increased current handling capacity (1 A versus 580 mA). These characteristics result in lower power dissipation and improved thermal performance in the application circuit.

Environmental and Compliance Alignment: Both components maintain ROHS3 compliance and are suitable for industrial temperature applications. The substitute part extends the operating temperature range to -40°C to 125°C, providing broader environmental coverage.

Product Status Consideration: The substitute part is classified as active product status, ensuring ongoing availability and supply chain support. This addresses the obsolescence constraint of the original LHLP10TB331KB.

Physical Integration: The maximum seated height difference of 0.020" (0.50mm) between components is negligible for standard through-hole PCB applications and does not present mechanical integration constraints.

Frequently Asked Questions (FAQ)

Q: Can the 7447471331 be used as a direct replacement for the LHLP10TB331KB in existing designs?

A: Yes. Both components share identical inductance values (330 µH), ferrite core material, shielding configuration, and through-hole radial mounting. Physical dimensions are compatible with negligible height variation (0.50mm). The substitute part meets or exceeds all electrical performance requirements of the original component.

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

A: The primary differences are: (1) DC resistance is lower in the substitute (480 mOhm versus 880 mOhm), resulting in reduced power loss; (2) current rating is higher (1 A versus 580 mA); (3) operating temperature range is extended (-40°C to 125°C versus -25°C to 105°C); (4) inductance tolerance is wider (±20% versus ±10%); (5) product status differs (active versus obsolete).

Q: Are there any circuit performance implications when substituting the 7447471331 for the LHLP10TB331KB?

A: The substitute part's lower DC resistance and higher current rating provide improved electrical performance with reduced power dissipation. The wider inductance tolerance (±20% versus ±10%) may require circuit validation in applications with tight inductance specifications. The extended operating temperature range supports broader environmental deployment.

Q: Is the physical package compatible with existing PCB layouts designed for the LHLP10TB331KB?

A: Yes. Both components use identical radial, vertical cylinder packages with 11.00mm diameter footprints. The maximum seated height difference of 0.50mm is within standard PCB design tolerances for through-hole components and does not require layout modifications.

Q: Do both components meet the same regulatory and compliance standards?

A: Yes. Both the LHLP10TB331KB and 7447471331 are ROHS3 compliant. Both components carry EAR99 ECCN classification and fall under the same HTSUS tariff code (8504.50.8000). The substitute part includes REACH Unaffected status, confirming regulatory alignment.

Q: What is the inductance frequency test specification for each component?

A: The LHLP10TB331KB is tested at 796 kHz, while the 7447471331 is tested at 1 kHz. Both test frequencies are within standard inductor characterization ranges. The inductance values remain equivalent across these test frequencies for ferrite core shielded inductors in this specification class.
