FP3-R10-R Equivalent & Substitute Parts

Part Overview

The FP3-R10-R is a 100 nH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 19 A continuous current with a maximum DC resistance of 1.21 mOhm and operates across the temperature range of -40°C to 155°C. The part is classified as Active status and is RoHS Compliant.

Substitute parts are identified when equivalent inductance values, current ratings, and mounting compatibility align with the original specification, allowing for direct functional replacement in surface mount applications requiring 100 nH inductance at high current levels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FP3-R10-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 100 nH (matched exactly)
• Inductance test frequency: 100 kHz (matched exactly)
• Mounting type: Surface Mount (matched exactly)
• Package classification: Nonstandard (matched exactly)
• Packaging format: Tape & Reel (TR) (matched exactly)

Secondary Compatibility Factors:

• Current rating must equal or exceed 19 A
• DC resistance must be within acceptable limits for the application
• Operating temperature range must support the intended environment
• RoHS compliance status must be maintained

The IHLP2525CZERR10M01 from Vishay Dale satisfies all primary matching criteria and provides enhanced current handling capability (32.5 A rated, 60 A saturation) compared to the original part, with comparable DC resistance characteristics.

Engineering Selection Recommendations

FP3-R10-R Selection Criteria:

• Applications requiring unshielded inductor construction
• Operating environments with maximum temperature requirements up to 155°C
• Systems where the original Eaton FLAT-PAC 3 series integration is specified
• Current loads up to 19 A continuous operation

IHLP2525CZERR10M01 Selection Criteria:

• Applications benefiting from shielded inductor construction to reduce electromagnetic interference
• Current loads between 19 A and 32.5 A continuous operation
• Systems operating within the -55°C to 125°C temperature range
• Designs requiring ROHS3 compliance certification
• Applications where higher saturation current (60 A) provides additional design margin

Both parts maintain Active product status and are available in production quantities. The substitute part provides increased current handling capacity and shielding characteristics while maintaining the same 100 nH inductance specification and surface mount compatibility.

Frequently Asked Questions (FAQ)

Q: Can IHLP2525CZERR10M01 directly replace FP3-R10-R in all applications?

A: Direct replacement is valid when the application current requirement does not exceed 19 A and the operating temperature range remains within -40°C to 155°C. The substitute part's shielded construction and higher current rating do not create incompatibility with the original specification. Physical dimensions differ slightly (0.270" L x 0.255" W vs. 0.285" L x 0.264" W), requiring PCB layout verification.

Q: What is the impact of the shielding difference between these parts?

A: The FP3-R10-R is unshielded, while IHLP2525CZERR10M01 is shielded. Shielding reduces electromagnetic field radiation and susceptibility to external interference. Selection depends on circuit layout and EMI requirements. Unshielded inductors typically occupy less board space and may be preferred in low-interference environments.

Q: How do the DC resistance values affect circuit performance?

A: FP3-R10-R specifies 1.21 mOhm maximum DCR, while IHLP2525CZERR10M01 specifies 1.7 mOhm maximum. The 0.49 mOhm difference results in increased power dissipation in the substitute part. For 19 A operation, this represents approximately 0.44 mW additional loss. Circuit thermal analysis should confirm acceptability in the target application.

Q: Are there temperature range limitations when substituting?

A: FP3-R10-R operates from -40°C to 155°C, while IHLP2525CZERR10M01 operates from -55°C to 125°C. The substitute part has a lower maximum temperature rating. Applications requiring operation above 125°C must use the original FP3-R10-R. The substitute part provides extended low-temperature capability to -55°C.

Q: What packaging considerations apply to these parts?

A: Both parts are supplied in Tape & Reel (TR) format for automated assembly. Both are classified as Nonstandard package types with identical height (0.118" / 3.00mm maximum seated height). Slight length and width variations require PCB footprint verification before design release.

Q: Do both parts meet current regulatory compliance requirements?

A: FP3-R10-R is RoHS Compliant. IHLP2525CZERR10M01 is ROHS3 Compliant and REACH Unaffected. Both parts satisfy RoHS requirements. ROHS3 represents the current regulatory standard. Both parts carry EAR99 ECCN classification and 8504.50.4000 HTSUS code.
