Substitute Part Grouping Explanation

Substitution of the 6000-100K-RC is determined by strict equivalence across the following critical parameters:

Inductance value: 10 µH with ±10% tolerance
Current rating: 3.4 A minimum
DC resistance: 45 mOhm maximum
Core material and shielding: Ferrite, unshielded
Physical form factor: Radial, vertical cylinder through-hole package
Mechanical dimensions: 0.354" diameter, 0.480" maximum seated height
Electrical performance: Q factor of 50 @ 2.52 MHz and 14 MHz self-resonant frequency

The RLB9012-100KL meets all these electrical and mechanical requirements, providing a direct functional equivalent with identical inductance, current handling, and DC resistance specifications. Both components share the same core construction, package geometry, and thermal operating envelope within their respective temperature ranges.

Engineering Selection Recommendations

The RLB9012-100KL is the direct equivalent for the 6000-100K-RC. Both components are manufactured by Bourns Inc. and share identical electrical specifications, mechanical form factors, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The primary distinction is product lifecycle status: the 6000-100K-RC is designated "Not For New Designs," while the RLB9012-100KL maintains active production status. For applications currently using the 6000-100K-RC, the RLB9012-100KL provides a direct replacement with no circuit redesign required. The RLB9012-100KL's extended operating temperature range to 125°C offers additional thermal margin compared to the 105°C limit of the legacy part.

Both components meet identical regulatory and compliance requirements, ensuring no changes to supply chain documentation or certification status.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-100KL directly replace the 6000-100K-RC in existing designs?

A: Yes. The RLB9012-100KL is electrically and mechanically equivalent. All critical parameters—inductance, current rating, DC resistance, core type, package geometry, and operating temperature range—are identical or superior. No circuit modifications are required.

Q: What is the difference in packaging between these parts?

A: The 6000-100K-RC is supplied in Bulk packaging, while the RLB9012-100KL is supplied in Tray packaging. Both components have identical physical dimensions and through-hole radial, vertical cylinder form factors. Packaging differences do not affect component performance or PCB mounting.

Q: Are there temperature range differences?

A: The RLB9012-100KL operates from -55°C to 125°C, while the 6000-100K-RC operates from -55°C to 105°C. The RLB9012-100KL provides 20°C additional upper temperature capability, making it suitable for higher thermal environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 6000-100K-RC and RLB9012-100KL are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: Why is the 6000-100K-RC marked "Not For New Designs"?

A: This designation indicates the part is in legacy status. Bourns Inc. recommends the RLB9012-100KL for new applications. Existing designs using the 6000-100K-RC can transition to the RLB9012-100KL without technical modifications.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts exhibit Q factor of 50 @ 2.52 MHz and self-resonant frequency of 14 MHz. DC resistance, inductance tolerance, and current ratings are identical.
