FP3-100-R Equivalent & Substitute Parts Reference

Part Overview

The FP3-100-R is a 10 µH shielded drum core wirewound inductor manufactured by Eaton Electronics Division, rated for 2.3 A continuous current with a maximum DC resistance of 101 mOhm. This component operates across the temperature range of -40°C to 155°C and is classified as Active product status with RoHS compliance. Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while accommodating different packaging formats or inventory availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FP3-100-R is determined by the following critical parameters: inductance value (10 µH), shielding requirement (shielded), surface mount configuration, and operating temperature compatibility. Substitute parts must maintain the 10 µH inductance specification and shielded construction. Current rating and DC resistance are secondary selection criteria; substitute parts with equal or higher current ratings and equal or lower DC resistance values provide equivalent or improved performance. Tolerance variations within ±20% are acceptable for this inductor category. All substitute candidates must be Active status products with RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

IHLP2525CZER100M01 (Vishay Dale): This substitute maintains the 10 µH inductance and shielded construction with a higher current rating of 3 A and saturation current of 7 A. DC resistance of 105 mOhm is marginally higher than the FP3-100-R specification. Operating temperature range is -55°C to 125°C, which covers the lower temperature extreme but does not extend to the upper 155°C limit of the original part. ROHS3 compliance is confirmed. This part is suitable for applications where the upper temperature limit does not exceed 125°C.

SRP7028A-100M (Bourns Inc.): This substitute provides superior electrical performance with a 3.5 A current rating, 6 A saturation current, and lower DC resistance of 85 mOhm. Operating temperature range of -40°C to 150°C aligns closely with the FP3-100-R specification. AEC-Q200 automotive qualification and ROHS3 compliance are documented. Q factor of 20 at 100 kHz and self-resonant frequency of 14 MHz are provided. This part is suitable for applications requiring the full temperature range up to 150°C and offers improved electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can IHLP2525CZER100M01 replace FP3-100-R in all applications?

A: IHLP2525CZER100M01 is suitable for applications where the maximum operating temperature does not exceed 125°C. The FP3-100-R operates to 155°C; therefore, this substitute is not appropriate for high-temperature applications approaching the upper limit of the original specification.

Q: What is the primary advantage of SRP7028A-100M over FP3-100-R?

A: SRP7028A-100M provides lower DC resistance (85 mOhm versus 101 mOhm), higher current rating (3.5 A versus 2.3 A), and higher saturation current (6 A versus 3 A). Operating temperature range extends to 150°C, which is within 5°C of the original part's 155°C maximum.

Q: Are all three parts RoHS compliant?

A: Yes. FP3-100-R is RoHS Compliant. Both IHLP2525CZER100M01 and SRP7028A-100M are ROHS3 Compliant, which represents the current RoHS standard.

Q: What is the difference between drum core wirewound and molded inductor construction?

A: FP3-100-R and SRP7028A-100M use drum core wirewound construction with iron powder and carbonyl powder cores respectively. IHLP2525CZER100M01 uses molded construction. All three maintain shielded configuration and are suitable for surface mount applications.

Q: Can these parts be used interchangeably in PCB designs?

A: Physical dimensions are similar (approximately 7.25mm × 6.70mm × 3.00mm for FP3-100-R, 6.86mm × 6.47mm × 3.00mm for IHLP2525CZER100M01, and 7.30mm × 6.60mm × 3.00mm for SRP7028A-100M). Verify PCB footprint compatibility before substitution. All three are nonstandard package types; consult component datasheets for exact land pattern requirements.

Q: Which substitute part has the lowest DC resistance?

A: SRP7028A-100M has the lowest DC resistance at 85 mOhm maximum, compared to 101 mOhm for FP3-100-R and 105 mOhm for IHLP2525CZER100M01.

Q: Is AEC-Q200 qualification important for my application?

A: AEC-Q200 qualification indicates automotive-grade reliability testing. SRP7028A-100M carries this qualification; FP3-100-R and IHLP2525CZER100M01 do not list this certification. Select SRP7028A-100M if automotive-grade components are required.
