Bourns 6710 Equivalent & Substitute Parts

Part Overview

The Bourns 6710 is a 1 mH shielded toroidal inductor rated for 1.5 A with a maximum DC resistance of 980 mOhm. This through-hole component features an iron powder core and operates across a temperature range of -55°C to 105°C. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain the same inductance value, core material, shielding characteristics, and through-hole mounting configuration to ensure functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Bourns 6710 must satisfy the following criteria:

• Inductance Value: Exactly 1 mH at 1 kHz test frequency
• Core Type: Iron powder material for equivalent magnetic characteristics
• Shielding: Shielded configuration to maintain EMI performance
• Mounting: Through-hole radial or vertical orientation
• Tolerance: ±15% inductance tolerance
• Current Capability: Equal to or greater than 1.5 A rating
• DC Resistance: Lower or equal to 980 mOhm maximum

The API Delevan PT1000-1400 meets these substitution criteria with improved current handling (1.8 A) and reduced DC resistance (620 mOhm), making it a direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan PT1000-1400 is the qualified substitute for the Bourns 6710. Both components share identical inductance specifications, core material composition, and shielding characteristics. The PT1000-1400 provides superior electrical performance with 20% higher current capacity (1.8 A versus 1.5 A) and 37% lower DC resistance (620 mOhm versus 980 mOhm), resulting in reduced power dissipation in equivalent circuit applications.

The PT1000-1400 maintains active product status, ensuring long-term availability and supply chain continuity. Both parts carry identical REACH and ECCN classifications, supporting equivalent regulatory compliance pathways. Physical dimensions differ between the two components; circuit board layout verification is required during substitution to confirm mechanical fit within the target application.

Frequently Asked Questions (FAQ)

Q: Can the PT1000-1400 directly replace the Bourns 6710 in existing designs?

A: Yes, the PT1000-1400 is functionally equivalent for applications requiring 1 mH inductance at 1.5 A or lower current levels. The improved current rating and reduced DC resistance provide performance margin. Physical dimensions must be verified against available board space, as the PT1000-1400 has a larger diameter (1.400" versus 1.125").

Q: What are the key differences between these two inductors?

A: Both components share identical inductance (1 mH), tolerance (±15%), core material (iron powder), and shielding. The PT1000-1400 offers higher current capacity (1.8 A versus 1.5 A) and lower DC resistance (620 mOhm versus 980 mOhm). The Bourns 6710 is obsolete; the PT1000-1400 is in active production.

Q: Are there any compliance or regulatory differences?

A: Both parts are RoHS non-compliant and REACH unaffected with identical ECCN classification (EAR99). No regulatory advantage exists between the two components.

Q: Does the lower DC resistance of the PT1000-1400 affect circuit performance?

A: Lower DC resistance reduces I²R power dissipation in the inductor. For applications operating at or below 1.5 A, this results in lower heat generation and improved thermal performance without altering the inductance or filtering characteristics.

Q: What mounting considerations apply to substitution?

A: Both inductors use through-hole radial/vertical mounting. The PT1000-1400 has a larger footprint (1.400" diameter versus 1.125"). PCB layout must accommodate the increased size; lead spacing and height clearance should be verified before implementation.
