RL0607-100-R Equivalent & Substitute Parts
Part Overview
The RL0607-100-R is a 10 µH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This through-hole component is rated for 1.82 A continuous current with a maximum DC resistance of 58 mOhm and operates across the temperature range of -40°C to 125°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation
Substitution of the RL0607-100-R is determined by the following critical parameters:
Primary Matching Criteria:
- Inductance value: 10 µH with ±10% tolerance
- Core type: Ferrite drum core, unshielded
- Mounting configuration: Through-hole radial, vertical cylinder
- Package footprint compatibility: Physical dimensions must accommodate board layout constraints
Secondary Compatibility Factors:
- Current rating must equal or exceed 1.82 A
- DC resistance must not exceed 58 mOhm to maintain circuit performance
- Operating temperature range must encompass or exceed -40°C to 125°C
- Self-resonant frequency characteristics must support intended application frequency
The RL824-100K-RC from Bourns Inc. satisfies these substitution criteria through matching inductance, core material, shielding configuration, and mounting type, while providing enhanced current handling and lower DC resistance.

Engineering Selection Recommendations
RL824-100K-RC Substitution Basis:
The RL824-100K-RC is an active product from Bourns Inc. with ROHS3 compliance and REACH unaffected status, providing long-term availability and regulatory alignment. This substitute meets all primary electrical specifications: matching 10 µH inductance with ±10% tolerance, ferrite drum core construction, and through-hole radial mounting configuration.
The RL824-100K-RC provides performance advantages over the obsolete RL0607-100-R through higher current rating (2.2 A versus 1.82 A) and lower DC resistance (52 mOhm versus 58 mOhm maximum). The elevated self-resonant frequency (44 MHz versus 21 MHz) extends high-frequency performance capability.
Physical Dimension Consideration:
The RL824-100K-RC exhibits larger physical dimensions (0.413" diameter, 0.610" height) compared to the RL0607-100-R (0.224" diameter, 0.287" height). Board layout verification is required to confirm footprint accommodation before implementation.
Temperature Range Note:
The RL824-100K-RC operating range (-55°C to 105°C) does not extend to the upper limit of the original specification (125°C). Application thermal requirements must be evaluated to confirm suitability.
Frequently Asked Questions (FAQ)
Q: Can the RL824-100K-RC directly replace the RL0607-100-R in existing designs?
A: Electrical substitution is valid based on matching inductance, tolerance, core material, and mounting type. Physical board layout must be verified due to larger component dimensions. Thermal operating range must be confirmed for applications requiring operation above 105°C.
Q: What are the key differences between these inductors?
A: Both components share identical inductance (10 µH), tolerance (±10%), core material (ferrite), and mounting configuration (through-hole radial). The RL824-100K-RC provides higher current capacity (2.2 A versus 1.82 A), lower DC resistance (52 mOhm versus 58 mOhm), and higher self-resonant frequency (44 MHz versus 21 MHz). Physical size is significantly larger.
Q: Why is the RL0607-100-R classified as obsolete?
A: Product status reflects manufacturer discontinuation. The RL824-100K-RC from Bourns represents an active equivalent with superior electrical performance and regulatory compliance.
Q: Are there packaging differences between these parts?
A: The RL0607-100-R is supplied in standard packaging. The RL824-100K-RC is supplied in bulk packaging. Both use identical through-hole radial, vertical cylinder package configuration.
Q: What compliance certifications apply to the substitute?
A: The RL824-100K-RC is ROHS3 compliant and REACH unaffected. Both parts carry EAR99 ECCN classification and 8504.50.4000 HTSUS code.
