Key Parameters

Substitute Part Grouping Explanation

Substitution of the RL110S-220M-RC is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 22 µH with ±20% tolerance
• DC resistance: 42 mOhm maximum
• Current rating: minimum 2.6 A (equal or higher acceptable)
• Shielding: shielded configuration required
• Package configuration: radial, vertical cylinder, 4 leads
• Mounting type: through-hole

The substitute part 12RS223C from Murata Power Solutions Inc. meets all critical electrical specifications and maintains mechanical compatibility with the original RL110S-220M-RC footprint and lead configuration.

Parameter Comparison

Engineering Selection Recommendations

The 12RS223C from Murata Power Solutions Inc. is a direct functional equivalent to the obsolete RL110S-220M-RC. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Murata part offers a higher current rating of 3.3 A compared to the original 2.6 A specification, providing additional design margin without compromising electrical performance. The operating temperature range of the substitute (-40°C ~ 85°C) overlaps the critical operating window of the original part, with the lower temperature limit extended to -40°C. Both components maintain identical inductance, DC resistance, shielding configuration, and mechanical footprint, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 12RS223C be used as a direct replacement for the RL110S-220M-RC in existing designs?

A: Yes. The 12RS223C maintains identical inductance (22 µH), DC resistance (42 mOhm max), shielding, and mechanical package configuration. The radial, vertical cylinder, 4-lead through-hole footprint is identical, allowing direct PCB substitution without layout modifications.

Q: What is the significance of the higher current rating on the substitute part?

A: The 12RS223C is rated for 3.3 A compared to the original 2.6 A. This higher rating provides additional thermal and electrical margin in the application without introducing incompatibility. The component will operate safely at or below the original 2.6 A specification.

Q: Are there temperature range considerations when substituting?

A: The original RL110S-220M-RC operates from -30°C to 100°C, while the 12RS223C operates from -40°C to 85°C. The substitute has a lower minimum temperature (-40°C vs -30°C) but a lower maximum temperature (85°C vs 100°C). Applications operating above 85°C require verification that the original upper temperature limit is not a critical design requirement.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the RL110S-220M-RC and 12RS223C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What parameters must remain constant for substitution to be valid?

A: Inductance value (22 µH ±20%), DC resistance (42 mOhm maximum), shielding configuration, package type (radial, vertical cylinder, 4 leads), and mounting method (through-hole) must all match. The current rating of the substitute must equal or exceed the original specification.
