Engineering Selection Recommendations
The 6000-2R2M-RC provides electrical and mechanical equivalence to the RLB9012-2R2ML across all critical inductance, current, and resistance parameters. Both components share identical physical dimensions, core construction, and mounting configuration, enabling direct board-level substitution.
The primary distinction between these parts is product lifecycle status. The RLB9012-2R2ML carries Active status, indicating ongoing manufacturer support and long-term availability. The 6000-2R2M-RC is designated Not For New Designs, reflecting its position in the Bourns product portfolio transition.
For applications operating at temperatures exceeding 105°C, the RLB9012-2R2ML is the required selection, as the 6000-2R2M-RC maximum operating temperature is limited to 105°C. Both components maintain full RoHS3 and REACH compliance, supporting regulatory requirements across global markets.
Frequently Asked Questions (FAQ)
Q: Can the 6000-2R2M-RC replace the RLB9012-2R2ML in existing designs?
A: The 6000-2R2M-RC provides electrical and mechanical compatibility for applications operating within the temperature range of -55°C to 105°C. Applications requiring operation above 105°C must use the RLB9012-2R2ML.
Q: What is the significance of the "Not For New Designs" status on the 6000-2R2M-RC?
A: This designation indicates the 6000-2R2M-RC is in the mature phase of its product lifecycle. New designs should prioritize the RLB9012-2R2ML to ensure long-term supply chain stability and manufacturer support.
Q: Are the physical dimensions identical between these parts?
A: Yes. Both the RLB9012-2R2ML and 6000-2R2M-RC share identical dimensions of 0.354" diameter and 0.480" maximum seated height, enabling direct board-level substitution without layout modifications.
Q: Do both parts meet the same regulatory compliance standards?
A: Both components are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for global deployment.
Q: What is the difference in packaging between these parts?
A: The RLB9012-2R2ML is supplied in Tray packaging, while the 6000-2R2M-RC is supplied in Bulk packaging. This distinction affects handling and inventory management but does not impact electrical or mechanical performance.
