Key Parameters

Substitute Part Grouping Explanation

The DR124-1R0-R from Eaton - Electronics Division qualifies as a substitute based on the following electrical and mechanical alignment criteria:

Inductance Compatibility: The substitute part specifies 1 µH nominal inductance with ±20% tolerance, which encompasses the 1.05 µH specification of the original part within acceptable design margins for fixed inductor applications.

Current Rating: The substitute part is rated for 13.9 A continuous current, exceeding the original part's 12.2 A rating, ensuring adequate current-carrying capacity for the same application circuit.

DC Resistance: The substitute part exhibits a maximum DC resistance of 3.6 mOhm, which is lower than the original part's 5.5 mOhm specification, resulting in reduced power dissipation and improved thermal performance.

Compliance and Environmental: Both parts maintain RoHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

Packaging and Mounting: The substitute part is supplied in Tape & Reel (TR) packaging as a surface mount component, suitable for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The DR124-1R0-R is suitable for direct substitution of the obsolete P0648.102NL based on electrical parameter alignment and active product status. The substitute part maintains full RoHS3 and REACH compliance, ensuring regulatory continuity. The improved current rating and reduced DC resistance of the substitute part provide enhanced performance margins without introducing compatibility concerns. Active availability of the DR124-1R0-R through Eaton - Electronics Division ensures long-term procurement reliability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the DR124-1R0-R directly replace the P0648.102NL in existing designs?

A: Yes. The inductance values are compatible within standard tolerance ranges (1.05 µH original vs. 1 µH ±20% substitute), and the substitute part exceeds the current rating requirement. No circuit redesign is necessary.

Q: What is the impact of the lower DC resistance in the substitute part?

A: The 3.6 mOhm maximum DCR of the substitute part compared to the 5.5 mOhm of the original part results in lower resistive losses and reduced heat generation during operation, improving overall circuit efficiency.

Q: Are there any packaging differences between the original and substitute parts?

A: The original part packaging is not specified in the available data. The substitute part DR124-1R0-R is supplied in Tape & Reel (TR) packaging as a surface mount component with dimensions of 12.50 mm × 12.50 mm and a seated height of 4.50 mm maximum. Verify mechanical fit within your PCB layout.

Q: What is the saturation current of the substitute part?

A: The DR124-1R0-R has a saturation current (Isat) of 18 A, providing additional margin above the 13.9 A continuous rating.

Q: Are both parts equally suitable for high-temperature applications?

A: The substitute part specifies an operating temperature range of -40°C to 125°C. The original part's temperature range is not provided in the available documentation. Verify temperature requirements for your specific application.
