Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LPWI201610SR24T is determined by strict alignment across the following critical parameters:

Inductance value must match at 240 nH with the same ±20% tolerance specification. Current rating must be maintained at 4.7 A minimum with saturation current (Isat) at 5.1 A. The package format must be identical: 0806 (2016 Metric) surface mount. DC resistance must not exceed the original specification of 23 mOhm maximum. Shielding type must be shielded construction. Core material must be metal composite. Operating temperature range must span -40°C to 125°C. RoHS3 compliance and MSL 1 rating are required for regulatory and environmental compatibility.

The CIGT201610UMR24MNE from Samsung Electro-Mechanics meets all substitution criteria and is classified as an active product, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

The CIGT201610UMR24MNE is a direct functional equivalent to the LPWI201610SR24T. Both components are ROHS3 compliant and carry MSL 1 rating, ensuring regulatory and environmental compatibility. The Samsung part offers superior DC resistance performance at 21 mOhm maximum compared to the Littelfuse specification of 23 mOhm maximum, representing a performance advantage within the same tolerance band. The critical distinction is product status: the LPWI201610SR24T is obsolete, while the CIGT201610UMR24MNE maintains active status, ensuring continued availability and manufacturing support. For new designs or ongoing production requiring this inductance value and current rating in the 0806 package format, the Samsung part provides equivalent electrical performance with enhanced supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the CIGT201610UMR24MNE be used as a direct replacement for the LPWI201610SR24T?

A: Yes. Both components share identical inductance (240 nH), current rating (4.7 A), saturation current (5.1 A), package format (0806 / 2016 Metric), operating temperature range (-40°C to 125°C), shielding type (shielded), and core material (metal composite). The Samsung part meets or exceeds all electrical specifications of the Littelfuse part.

Q: What is the significance of the DC resistance difference between these parts?

A: The LPWI201610SR24T specifies 23 mOhm maximum DC resistance, while the CIGT201610UMR24MNE specifies 21 mOhm maximum. Both values fall within acceptable operating parameters for this inductance class. The lower resistance of the Samsung part represents improved efficiency characteristics with no compatibility concerns.

Q: Are there any package or footprint compatibility issues?

A: No. Both components use the identical 0806 (2016 Metric) surface mount package with matching physical dimensions (0.079" L x 0.063" W / 2.00mm x 1.60mm) and maximum seated height (0.039" / 1.00mm). PCB footprints and assembly processes are fully compatible.

Q: What is the impact of the product status difference?

A: The LPWI201610SR24T is classified as obsolete, indicating discontinued manufacturing and limited future availability. The CIGT201610UMR24MNE maintains active status, ensuring ongoing production, consistent supply, and manufacturer support for technical documentation and quality assurance.

Q: Are both parts RoHS compliant?

A: Yes. Both the LPWI201610SR24T and CIGT201610UMR24MNE are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and regulatory requirements.
