Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 6707 is determined by the following critical parameters:

• Inductance Value: Must be 75 µH with ±15% tolerance
• Current Rating: Minimum 5 A continuous current capability
• DC Resistance: Maximum 40 mOhm
• Core Material: Iron powder construction
• Shielding: Shielded configuration required
• Mounting: Through-hole radial vertical orientation
• Lead Configuration: 4-lead open package

The API Delevan PT75-980 meets all substitution criteria. It maintains identical inductance, tolerance, core material, shielding, and mounting specifications. The PT75-980 provides a higher current rating (5.2 A versus 5 A), which represents an improvement in current handling capability while maintaining the same DC resistance specification.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan PT75-980 is a direct functional equivalent to the obsolete Bourns 6707. Both components share identical electrical specifications for inductance, tolerance, and DC resistance, with matching core material and shielding characteristics. The PT75-980 carries active product status, ensuring ongoing availability and supply chain continuity.

Both parts maintain identical regulatory compliance profiles, classified as RoHS non-compliant and REACH unaffected. Export classification and tariff codes are identical, supporting seamless procurement transitions.

The PT75-980 offers enhanced current rating capability (5.2 A versus 5 A), providing additional design margin without compromising any other electrical or mechanical parameter. Physical dimensions differ slightly between the two designs, requiring verification of mechanical fit within the target application's PCB layout and enclosure constraints.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan PT75-980 directly replace the Bourns 6707 in existing designs?

A: The PT75-980 meets all electrical specifications required for functional equivalence. Physical dimensions differ, so mechanical fit must be verified against PCB layout and mounting constraints before implementation.

Q: What is the significance of the higher current rating on the PT75-980?

A: The PT75-980 is rated for 5.2 A continuous current compared to the Bourns 6707's 5 A rating. This represents improved current handling capability while maintaining identical DC resistance and inductance characteristics, providing additional design margin.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components share identical RoHS, REACH, ECCN, and HTSUS classifications. No compliance barriers exist for substitution from a regulatory standpoint.

Q: Why is the Bourns 6700 series classified as obsolete?

A: The Bourns 6700 series has reached end-of-life status. The API Delevan PT series provides active product alternatives with equivalent electrical performance and ongoing manufacturing support.

Q: What parameters must remain constant for substitution eligibility?

A: Inductance value (75 µH), tolerance (±15%), DC resistance (40 mOhm maximum), core material (iron powder), shielding (shielded), and mounting type (through-hole radial vertical) must all match or exceed the original specification.

Q: Are there any package or lead configuration differences?

A: Both components feature radial vertical through-hole mounting with open lead configurations. Physical dimensions and exact lead spacing differ slightly and require mechanical verification for PCB compatibility.
