Bourns 7002 Inductor Array - Equivalent & Substitute Parts

Part Overview

The Bourns 7002 is an unshielded 2-coil inductor array designed for through-hole mounting applications. This component features 6 µH series inductance with a 7 mOhm maximum DC resistance and supports 5.5 A series current rating across an operating temperature range of -55°C to 105°C. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Bourns 7002 requires evaluation based on the following critical parameters:

• Coil Configuration: Both main and substitute parts must feature 2-coil inductor arrays
• Series Inductance Value: The 6 µH series inductance is the primary functional specification
• Current Handling Capacity: Series current rating must meet or exceed 5.5 A
• DC Resistance: Lower DCR values indicate improved efficiency; the 7 mOhm maximum specification establishes the baseline
• Temperature Range: Operating temperature capability must support the -55°C to 105°C envelope
• Compliance Status: RoHS and REACH certifications affect regulatory acceptability in modern applications

The Pulse Electronics PF0552.332NLT qualifies as a functional substitute based on dual-coil architecture and comparable electrical performance in series configuration, despite differences in mounting technology and shielding approach.

Engineering Selection Recommendations

The Pulse Electronics PF0552.332NLT represents an active product with current manufacturing support and ROHS3 compliance, addressing the obsolescence status of the Bourns 7002. However, direct substitution requires circuit-level evaluation due to the following parameter deviations:

The series inductance value doubles from 6 µH to 12 µH, which directly affects circuit impedance and filtering characteristics. The DC resistance increases from 7 mOhm to 23 mOhm maximum, resulting in higher power dissipation. The series current rating decreases marginally from 5.5 A to 5 A. The mounting transition from through-hole radial to surface-mount nonstandard package necessitates PCB redesign.

Selection of the PF0552.332NLT is appropriate for applications where the higher inductance value and increased temperature range (-40°C to 125°C) provide functional advantages, and where PCB layout can accommodate surface-mount technology. The ROHS3 compliance status supports deployment in regulated markets.

Frequently Asked Questions (FAQ)

Q: Can the Pulse Electronics PF0552.332NLT directly replace the Bourns 7002 without circuit modification?

A: No. The doubled series inductance (12 µH vs. 6 µH) and increased DC resistance (23 mOhm vs. 7 mOhm) alter circuit behavior. Circuit analysis is required to confirm functional equivalence for the specific application.

Q: What is the impact of the mounting type difference between through-hole and surface-mount?

A: Through-hole and surface-mount components require different PCB footprints and assembly processes. Transition to surface-mount technology necessitates PCB redesign and updated manufacturing procedures.

Q: Does the shielded design of the PF0552.332NLT provide advantages over the unshielded Bourns 7002?

A: Shielding reduces electromagnetic interference coupling to adjacent circuits. Selection depends on EMI environment and circuit sensitivity requirements.

Q: How does the RoHS compliance difference affect component selection?

A: The Bourns 7002 is RoHS non-compliant, while the PF0552.332NLT is ROHS3 compliant. Regulatory requirements for the end application determine whether compliance status is a selection criterion.

Q: What is the significance of the tolerance difference (±15% vs. ±20%)?

A: The Bourns 7002 offers tighter tolerance control. Applications requiring precise inductance values may require additional circuit compensation when using the PF0552.332NLT.
