FP1007R1-R14-R Equivalent & Substitute Parts

Part Overview

The FP1007R1-R14-R is a 140 nH unshielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 60 A continuous current with a saturation current of 72 A and a DC resistance of 0.29 mOhm. The part is actively produced and RoHS compliant, designed for applications requiring low inductance values with high current handling capability in compact form factors.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances and mechanical constraints of the application. The primary substitute identified is the PA2607.151NLT from Pulse Electronics, which shares critical electrical characteristics while offering alternative shielding and dimensional properties.

Substitute Part Grouping Explanation

Substitution eligibility for the FP1007R1-R14-R is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Inductance value within tolerance band (140 nH ±10% = 126 nH to 154 nH)
• DC resistance matching at 0.29 mOhm
• Saturation current rating of 72 A or higher
• Continuous current rating sufficient for application requirements
• Inductance test frequency at 100 kHz

Mechanical Compatibility Criteria:

• Surface mount packaging format
• Nonstandard package case type
• Physical dimensions compatible with PCB layout constraints
• Height clearance within 7.00 mm seated maximum

Environmental & Compliance Criteria:

• Operating temperature range overlap (-40°C minimum, 125°C minimum upper limit)
• RoHS compliance status
• Moisture sensitivity level 1 (unlimited)

The PA2607.151NLT meets these substitution criteria with inductance of 150 nH (within the 126–154 nH tolerance band), matching DC resistance of 0.29 mOhm, saturation current of 72 A, and extended operating temperature to 130°C. The primary difference is shielded construction versus unshielded, which affects electromagnetic interference characteristics but does not preclude substitution in applications where shielding is beneficial or neutral.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Continuous Current Rating

The FP1007R1-R14-R is rated for 60 A continuous current, while the PA2607.151NLT is rated for 41 A continuous current. Selection between these parts must be based on the actual continuous current requirement of the application. If the application requires continuous current operation above 41 A, the FP1007R1-R14-R is the only suitable choice. If continuous current does not exceed 41 A, the PA2607.151NLT is electrically compatible.

Secondary Consideration: Physical Dimensions

The PA2607.151NLT is 0.40 mm taller (7.40 mm vs. 7.00 mm seated height). PCB layout and enclosure clearance must accommodate this height difference. The footprint differences (0.11 mm length, 0.15 mm width) are negligible for most applications.

Shielding Characteristics

The FP1007R1-R14-R is unshielded; the PA2607.151NLT is shielded. In applications where electromagnetic interference rejection is required, the shielded substitute provides additional performance. In applications where shielding is not required, both parts function equivalently from an electrical standpoint.

Compliance & Product Status

Both parts are actively produced and fully compliant with current environmental standards (RoHS3 for the substitute, RoHS for the main part). Both carry MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling.

Inductance Value Variance

The 10 nH difference between 140 nH and 150 nH represents a 7.1% variance. This falls within the combined tolerance bands and is acceptable for general filtering, impedance matching, and EMI suppression applications where inductance values are not critical to circuit function. Applications requiring precise inductance values should verify circuit performance with the 150 nH value.

Frequently Asked Questions (FAQ)

Q: Can the PA2607.151NLT directly replace the FP1007R1-R14-R in all applications?

A: No. The PA2607.151NLT has a continuous current rating of 41 A compared to 60 A for the FP1007R1-R14-R. Direct substitution is only valid if the application's continuous current requirement does not exceed 41 A. Both parts share identical saturation current (72 A), so peak current handling is equivalent.

Q: What is the significance of the 10 nH inductance difference between the two parts?

A: The FP1007R1-R14-R is 140 nH and the PA2607.151NLT is 150 nH. This 7.1% difference falls within the combined tolerance specifications (±10% and ±15% respectively). For applications where inductance value is non-critical (general filtering, impedance matching), this variance is acceptable. For precision applications, circuit simulation or testing with the 150 nH value is necessary to confirm performance.

Q: Does the shielded construction of the PA2607.151NLT affect compatibility?

A: Shielding affects electromagnetic interference characteristics but does not prevent substitution. The shielded design of the PA2607.151NLT provides additional EMI rejection compared to the unshielded FP1007R1-R14-R. In applications where EMI performance is critical, the shielded substitute may offer improved performance. In applications where shielding is not required, both parts are functionally equivalent.

Q: Are there height clearance concerns with the PA2607.151NLT?

A: Yes. The PA2607.151NLT has a maximum seated height of 7.40 mm compared to 7.00 mm for the FP1007R1-R14-R. This 0.40 mm difference must be verified against PCB layout constraints and enclosure clearance requirements. If height is constrained, the FP1007R1-R14-R is the only suitable option.

Q: Do both parts meet current environmental compliance standards?

A: Yes. The FP1007R1-R14-R is RoHS compliant. The PA2607.151NLT is ROHS3 compliant, which represents the current RoHS standard. Both parts carry MSL 1 rating (unlimited moisture sensitivity), indicating no special storage or handling requirements.

Q: What is the DC resistance impact on power dissipation?

A: Both parts have identical DC resistance of 0.29 mOhm. Power dissipation at a given current level is therefore equivalent between the two parts. For example, at 40 A continuous current, both parts dissipate approximately 0.464 W (I²R = 40² × 0.29 × 10⁻³).

Q: Can the PA2607.151NLT be used in applications requiring the full 60 A continuous rating of the FP1007R1-R14-R?

A: No. The PA2607.151NLT is rated for 41 A continuous current maximum. Operating above this rating will cause excessive temperature rise and potential component failure. The FP1007R1-R14-R must be used for applications requiring 60 A continuous current operation.

Q: Are the package dimensions compatible with existing PCB layouts designed for the FP1007R1-R14-R?

A: Largely yes, with verification required. The PA2607.151NLT footprint is 10.31 mm × 7.65 mm compared to 10.20 mm × 7.80 mm for the FP1007R1-R14-R. The length difference is 0.11 mm and the width difference is 0.15 mm. These are minimal variations that typically do not affect PCB layout compatibility. However, the 0.40 mm height difference must be verified against clearance constraints.
