Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 6707-RC 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 Type: Iron powder construction
• Shielding: Shielded configuration required
• Mounting: Through-hole radial/vertical orientation
• Test Frequency: 1 kHz inductance measurement standard

The API Delevan PT75-980 meets all electrical substitution criteria, with a current rating of 5.2 A (exceeding the 5 A requirement) and identical inductance, tolerance, DC resistance, core material, and shielding specifications.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan PT75-980 is electrically equivalent to the Bourns 6707-RC across all specified performance parameters. The substitute part provides a current rating margin of 0.2 A above the original specification, maintaining identical inductance, tolerance, and DC resistance characteristics.

Compliance consideration: The Bourns 6707-RC is ROHS3 compliant, while the API Delevan PT75-980 is RoHS non-compliant. Design environments with RoHS compliance requirements must account for this regulatory difference. Both parts are REACH unaffected and classified under ECCN EAR99.

Physical dimensions differ between the two parts. The Bourns 6707-RC measures 1.125" L × 0.600" W with a seated height of 1.250", while the API Delevan PT75-980 measures 0.980" diameter × 0.380" width. PCB layout and mechanical clearance must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Can the API Delevan PT75-980 directly replace the Bourns 6707-RC in all applications?

A: Electrical substitution is valid based on matching inductance, current rating, DC resistance, core material, and shielding. Physical dimensions and RoHS compliance status must be evaluated for your specific application.

Q: What is the significance of the current rating difference (5 A vs. 5.2 A)?

A: The PT75-980 exceeds the minimum current requirement, providing operational margin. Both parts are rated for the same DC resistance and inductance characteristics at their respective current ratings.

Q: Are there mechanical compatibility concerns?

A: Yes. The PT75-980 has a smaller footprint (0.980" diameter vs. 1.125" length). Verify PCB hole spacing, lead positioning, and available board area before implementation.

Q: Does RoHS compliance affect electrical performance?

A: RoHS status does not alter electrical performance. However, if your design or end-use market requires RoHS compliance, the Bourns 6707-RC is the compliant option. The API Delevan PT75-980 is non-compliant and unsuitable for RoHS-regulated applications.

Q: What is the moisture sensitivity level (MSL) for the substitute part?

A: The API Delevan PT75-980 is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
