PI60-02-FPIZ Equivalent & Substitute Parts

Part Overview

The PI60-02-FPIZ is a fixed unshielded inductor manufactured by Vicor Corporation, rated for 80 nH inductance with a maximum current capacity of 90 A and DC resistance of 0.5 mOhm. This component is designed for surface mount applications in high-current power conversion circuits. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI60-02-FPIZ is evaluated based on the following critical parameters:

Inductance Value: The substitute must fall within the ±10% tolerance band of 80 nH (72–88 nH range). The FPV1006-85-R at 85 nH satisfies this requirement.

Current Rating: The substitute must support the application's current demands. While the FPV1006-85-R is rated for 25 A, this represents a significant reduction from the original 90 A specification and must be evaluated against actual circuit requirements.

DC Resistance: Lower DCR values are preferred to minimize power loss. The FPV1006-85-R at 0.41 mOhm is superior to the original 0.5 mOhm specification.

Core Material and Shielding: Both parts use ferrite core material. The original is unshielded; the substitute is shielded, which may affect electromagnetic compatibility characteristics in the application.

Operating Temperature Range: Both parts support -55°C ~ 125°C, ensuring thermal compatibility.

Physical Footprint: Dimensions are nearly identical (9.70mm L x 8.40mm W vs. 9.70mm L x 8.10mm W), with height matching at 6.40mm, allowing direct mechanical substitution in most layouts.

Engineering Selection Recommendations

The FPV1006-85-R from Eaton Electronics Division is an active product with current manufacturing support, addressing the obsolescence status of the PI60-02-FPIZ. Both components meet RoHS compliance requirements and operate across the same temperature range.

The primary consideration for substitution is current rating. The FPV1006-85-R is rated for 25 A, compared to the original 90 A specification. This substitution is only appropriate for applications where the actual operating current does not exceed 25 A. For circuits requiring the full 90 A capacity of the original part, alternative sources or redesign may be necessary.

The inductance values are within tolerance (80 nH vs. 85 nH), and the superior DCR of the substitute (0.41 mOhm vs. 0.5 mOhm) provides improved efficiency. The shift from unshielded to shielded construction may reduce electromagnetic emissions but should be evaluated for any EMI/EMC implications specific to the application.

Physical footprint compatibility is confirmed, allowing direct PCB layout substitution without redesign.

Frequently Asked Questions (FAQ)

Q: Can the FPV1006-85-R directly replace the PI60-02-FPIZ in all applications?

A: Direct substitution is limited by current rating. The FPV1006-85-R is rated for 25 A maximum, while the original supports 90 A. Substitution is valid only for applications operating below 25 A. For higher-current designs, alternative components must be sourced.

Q: What is the inductance tolerance impact of using 85 nH instead of 80 nH?

A: The 5 nH difference represents a 6.25% increase, which falls within the ±10% tolerance specification of both components. This variance is acceptable for most power conversion applications where inductance tolerance is the controlling specification.

Q: Does the shielded construction of the FPV1006-85-R affect compatibility?

A: Shielding reduces electromagnetic radiation and may improve EMI performance. However, shielded inductors typically exhibit different parasitic characteristics than unshielded designs. Circuit-level validation is recommended if EMI performance is critical to the application.

Q: Are both components RoHS compliant?

A: Yes. The PI60-02-FPIZ is ROHS3 compliant, and the FPV1006-85-R is RoHS compliant. Both meet environmental regulatory requirements for lead-free manufacturing.

Q: What is the packaging difference between these parts?

A: The PI60-02-FPIZ uses standard 2-SMD packaging. The FPV1006-85-R is supplied in Tape & Reel format, which is standard for high-volume production. Both have identical physical dimensions and mounting footprints.

Q: Why is the PI60-02-FPIZ obsolete?

A: The part is classified as obsolete by the manufacturer. The FPV1006-85-R, as an active product from Eaton, provides ongoing manufacturing support and availability for new designs or legacy system maintenance.
