RL110S-151L-RC Equivalent & Substitute Parts

Part Overview

The RL110S-151L-RC is a 150 µH shielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1 A continuous current with a maximum DC resistance of 230mOhm. This component is designed for through-hole mounting in radial, vertical cylinder configuration with 4 leads. The part is currently obsolete, making identification of suitable substitute components essential for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RL110S-151L-RC is determined by the following critical parameters:

• Inductance value: 150 µH with ±15% tolerance
• DC resistance: 230mOhm maximum
• Current rating: minimum 1 A
• Shielding requirement: shielded construction
• Package configuration: radial, vertical cylinder, 4 leads through-hole mounting
• Physical compatibility: footprint and height constraints

The substitute part 12RS154C from Murata Power Solutions Inc. meets these core electrical and mechanical requirements, enabling direct functional replacement in applications where the RL110S-151L-RC is specified.

Parameter Comparison

Engineering Selection Recommendations

The 12RS154C from Murata Power Solutions Inc. is an active product suitable for replacing the obsolete RL110S-151L-RC. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

The substitute part provides equivalent electrical performance with a higher current rating (1.25 A versus 1 A), offering improved thermal margin in the application. Physical dimensions are compatible with PCB layouts designed for the original part, with the substitute featuring a slightly larger diameter and reduced height.

Temperature range consideration is required: the substitute operates to 85°C maximum versus the original 100°C maximum. Applications requiring operation above 85°C must evaluate thermal performance independently.

Frequently Asked Questions (FAQ)

Q: Can the 12RS154C directly replace the RL110S-151L-RC on existing PCBs?

A: Yes. Both components share identical package configuration (radial, vertical cylinder, 4 leads through-hole), inductance value (150 µH ±15%), and DC resistance (230mOhm max). Physical dimensions are compatible with standard PCB footprints designed for the original part.

Q: What is the impact of the higher current rating on the 12RS154C?

A: The substitute's 1.25 A rating exceeds the original 1 A specification, providing additional thermal headroom. This does not create compatibility issues; the component will perform safely in applications rated for 1 A operation.

Q: Are there temperature range limitations when substituting?

A: The 12RS154C operates from -40°C to 85°C, compared to the original -30°C to 100°C range. Applications requiring sustained operation above 85°C should verify thermal performance independently. The overlap range (-30°C to 85°C) covers most standard industrial and commercial applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RL110S-151L-RC and 12RS154C are ROHS3 compliant and REACH unaffected, maintaining equivalent regulatory status for procurement and deployment.

Q: What are the physical dimension differences?

A: The 12RS154C has a slightly larger diameter (0.413" versus 0.394") and reduced height (0.335" versus 0.413"). These variations are within standard PCB layout tolerances and do not affect mechanical compatibility.
