Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6000-102K-RC is determined by strict equivalence across the following critical parameters:

• Inductance value: 1 mH with ±10% tolerance
• Current rating: 510 mA minimum
• DC resistance: 2.9 Ohm maximum
• Core material and shielding: Ferrite, unshielded
• Mounting configuration: Through-hole, radial vertical cylinder
• Physical footprint: 0.354" diameter, 0.480" maximum height
• Electrical performance: Q factor and self-resonant frequency characteristics

The RLB9012-102KL meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The RLB9012-102KL is the direct substitute for the 6000-102K-RC. Both components are manufactured by Bourns Inc. and share identical electrical and mechanical specifications across all critical parameters. The RLB9012-102KL offers the following advantages:

• Active product status ensures continued availability and manufacturing support
• Extended operating temperature range (-55°C to 125°C versus -55°C to 105°C) provides additional thermal margin
• Both parts maintain ROHS3 compliance and REACH unaffected status
• Identical inductance, current rating, DC resistance, and physical dimensions ensure direct PCB compatibility without layout modifications

Selection of the RLB9012-102KL is appropriate for new designs, production continuity, and replacement applications where the 6000-102K-RC is currently specified.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-102KL be used as a direct replacement for the 6000-102K-RC on existing PCBs?

A: Yes. Both components have identical physical dimensions (0.354" diameter, 0.480" maximum height), radial vertical cylinder package configuration, and through-hole mounting. No PCB layout modifications are required.

Q: Are there electrical performance differences between these parts?

A: No. Both inductors provide 1 mH inductance with ±10% tolerance, 510 mA current rating, 2.9 Ohm maximum DC resistance, and identical Q factor (20 @ 252 kHz) and self-resonant frequency (1.3 MHz) characteristics.

Q: What is the difference in operating temperature range?

A: The 6000-102K-RC operates from -55°C to 105°C, while the RLB9012-102KL extends to 125°C. For applications operating near the upper temperature limit of the legacy part, the RLB9012-102KL provides additional thermal headroom.

Q: Why is the 6000-102K-RC marked "Not For New Designs"?

A: This designation indicates the part has been superseded by the RLB9012-102KL in Bourns' product portfolio. The RLB9012 series represents the current active product line for this inductor specification.

Q: Are packaging differences significant?

A: The 6000-102K-RC is supplied in bulk packaging, while the RLB9012-102KL is supplied in tray packaging. Both are suitable for through-hole assembly; packaging selection depends on production volume and handling requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, classified as EAR99, and share the same HTSUS code (8504.50.8000).
