Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Bourns 6710-RC is determined by the following critical parameters:

• Inductance Value: Must be 1 mH (±15% tolerance)
• Current Rating: Must meet or exceed 1.5 A
• DC Resistance: Lower values are acceptable; higher values may impact circuit performance
• Core Material: Iron powder core required for equivalent magnetic characteristics
• Shielding: Shielded construction required
• Mounting Type: Through-hole configuration required
• Package Configuration: Radial, vertical lead orientation required

The API Delevan PT1000-1400 meets these substitution criteria with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The API Delevan PT1000-1400 is a direct functional substitute for the Bourns 6710-RC. The PT1000-1400 provides superior electrical performance with a higher current rating (1.8 A versus 1.5 A) and lower DC resistance (620 mOhm versus 980 mOhm). Both components share identical inductance values, tolerance specifications, core materials, and shielding characteristics.

The PT1000-1400 is classified as an active product with current manufacturing support, whereas the 6710-RC is obsolete. The PT1000-1400 is RoHS non-compliant; design teams requiring RoHS3 compliance should evaluate alternative sources or design modifications.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components have identical inductance values (1 mH), matching tolerance (±15%), iron powder cores, shielded construction, and through-hole mounting. The PT1000-1400 exceeds the current rating requirement and provides lower DC resistance, making it electrically compatible.

Q: What are the physical dimension differences?

A: The Bourns 6710-RC measures 1.125" L × 0.600" W with a maximum seated height of 1.250". The API Delevan PT1000-1400 measures 1.400" diameter × 0.550" width. PCB layout verification is required to confirm mechanical fit.

Q: Are there compliance differences between these parts?

A: The Bourns 6710-RC is RoHS3 compliant. The API Delevan PT1000-1400 is RoHS non-compliant. Both are REACH unaffected and classified under ECCN EAR99.

Q: What is the DC resistance impact of substitution?

A: The PT1000-1400 has lower DC resistance (620 mOhm maximum versus 980 mOhm maximum). This reduces power dissipation and heat generation in the inductor, improving overall circuit efficiency.

Q: Are operating temperature ranges equivalent?

A: The Bourns 6710-RC operates from -55°C to 105°C. Operating temperature specifications for the API Delevan PT1000-1400 were not provided in the available data.
