Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC11D562F is determined by the following critical parameters:

• Inductance Value: 5.6 mH with ±10% tolerance
• Current Rating: Minimum 230 mA capability
• DC Resistance: Acceptable range based on circuit design requirements
• Core Material: Ferrite drum core construction
• Shielding Configuration: Unshielded
• Mounting Interface: Through-hole radial leads
• Package Geometry: Radial, vertical cylinder form factor

The RLB9012-562KL from Bourns Inc. meets these substitution criteria, maintaining identical inductance value, equivalent tolerance, compatible current rating, and matching core type and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The RLB9012-562KL serves as a functional equivalent for the obsolete ELC11D562F based on the following factors:

Electrical Compatibility: Both components maintain 5.6 mH inductance with ±10% tolerance. The RLB9012-562KL current rating of 220 mA is within 4.3% of the original 230 mA specification, providing adequate margin for most applications. The higher DC resistance of 14.9 Ohm in the substitute requires circuit-level evaluation to confirm acceptable power dissipation and impedance characteristics.

Mechanical Fit: The RLB9012-562KL features a smaller physical footprint (0.354" diameter, 0.480" height) compared to the original (0.453" diameter, 0.547" height). PCB layout verification is necessary to confirm mounting compatibility within existing through-hole pad patterns.

Compliance Status: The RLB9012-562KL holds active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The original ELC11D562F, marked obsolete, presents supply chain risk.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-562KL directly replace the ELC11D562F without circuit modification?

A: Both components share identical inductance value and tolerance, matching core type, and equivalent mounting configuration. However, the 14.9 Ohm DC resistance of the substitute versus 6.9 Ohm of the original represents a 2.16x increase. Circuit analysis is required to confirm acceptable voltage drop and thermal performance at the specified 220 mA current level.

Q: What are the physical installation considerations?

A: The RLB9012-562KL is physically smaller in both diameter and height. Existing through-hole pad patterns must accommodate the smaller lead geometry. Mechanical clearance around the component should be verified to prevent interference with adjacent board-level components.

Q: Are there compliance or regulatory differences between these parts?

A: The ELC11D562F carries RoHS Compliant status, while the RLB9012-562KL is ROHS3 Compliant. Both meet RoHS requirements. The RLB9012-562KL includes REACH Unaffected designation, providing additional regulatory documentation.

Q: What is the current rating difference impact?

A: The RLB9012-562KL is rated for 220 mA versus the original 230 mA. This 10 mA reduction represents a 4.3% margin reduction. Applications operating near the original current limit require thermal and saturation analysis to confirm the substitute remains within safe operating parameters.

Q: How do the inductance test frequencies differ?

A: The ELC11D562F specifies inductance measurement at 10 kHz, while the RLB9012-562KL uses 1 kHz. Both measurements reflect the same nominal 5.6 mH value with ±10% tolerance. Frequency-dependent behavior should be evaluated for applications with critical frequency response requirements.
