Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LHL10TB820KB is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 82 µH (±10% tolerance)
• Inductance tolerance: ±10%
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through Hole
• Package configuration: Radial, Vertical Cylinder
• Physical footprint compatibility: 0.433" diameter

Secondary Compatibility Factors:

• Current rating: Substitute must equal or exceed 1.4 A
• DC resistance: Substitute must not exceed 130mOhm significantly
• Operating temperature range: Substitute must support minimum -25°C to 105°C
• RoHS compliance: ROHS3 Compliant status required

The Bourns 6100-820K-RC satisfies all primary matching criteria and exceeds secondary compatibility requirements through higher current rating (2.18 A) and extended temperature range (-40°C to 125°C), while maintaining identical inductance, tolerance, core material, shielding, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The Bourns 6100-820K-RC is a direct functional substitute for the obsolete Taiyo Yuden LHL10TB820KB. Both components maintain identical inductance specifications, tolerance bands, core materials, and physical form factors required for through-hole PCB mounting.

Compliance and Support Status: The LHL10TB820KB is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The 6100-820K-RC maintains active product status with Bourns Inc., ensuring continued supply chain support, technical documentation, and manufacturing consistency.

Electrical Performance: The 6100-820K-RC provides enhanced electrical performance margins through 55.7% higher current rating (2.18 A versus 1.4 A) and extended operating temperature range (-40°C to 125°C versus -25°C to 105°C). DC resistance remains within acceptable tolerance at 150mOhm maximum, representing a 15.4% increase from the original specification.

Regulatory Compliance: Both components maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity in design transitions.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 6100-820K-RC directly replace the Taiyo Yuden LHL10TB820KB in existing designs?

A: Yes. Both components share identical inductance (82 µH), tolerance (±10%), core material (ferrite), shielding configuration (unshielded), mounting type (through-hole), and physical package dimensions (0.433" diameter radial cylinder). PCB footprints and lead spacing are compatible.

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

A: The primary differences are current rating (2.18 A versus 1.4 A), DC resistance (150mOhm versus 130mOhm), operating temperature range (-40°C to 125°C versus -25°C to 105°C), and product status (active versus obsolete). The 6100-820K-RC features a drum core wirewound construction compared to the LHL10TB820KB design.

Q: Is the higher DC resistance of the 6100-820K-RC acceptable?

A: The 20mOhm increase (130mOhm to 150mOhm) represents a 15.4% rise in DC resistance. This remains within acceptable engineering tolerance for most applications. Circuit designers must verify power dissipation and thermal performance at the specified 1.4 A operating current to confirm suitability for their specific application.

Q: Does the substitute part require PCB layout modifications?

A: No. Both inductors maintain identical physical dimensions (0.433" diameter, radial vertical cylinder configuration). Existing through-hole PCB layouts require no modification for component substitution.

Q: What is the product status difference, and why does it matter?

A: The LHL10TB820KB is obsolete, indicating Taiyo Yuden has discontinued production. The 6100-820K-RC maintains active status with Bourns Inc., ensuring continued availability, technical support, and manufacturing consistency for future production runs and design revisions.

Q: Are both components RoHS compliant?

A: Yes. Both the LHL10TB820KB and 6100-820K-RC maintain ROHS3 compliance, ensuring regulatory compatibility in applications requiring lead-free component specifications.
