Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0316S-6R8N-T3 is determined by the following critical parameters:

Primary Electrical Criteria:

• Inductance value: 6.8 µH (exact match required)
• Current rating: minimum 790 mA to maintain design margin
• DC resistance: must not exceed 284 mOhm to preserve circuit performance
• Core material: ferrite drum core construction
• Shielding: shielded configuration

Mechanical & Environmental Criteria:

• Mounting type: surface mount
• Package footprint compatibility: 3.20mm × 3.20mm or smaller equivalent
• Operating temperature range: minimum -25°C to 100°C coverage
• Compliance: ROHS3 and REACH requirements

The substitute part NR3015T6R8M from Taiyo Yuden meets these substitution criteria with equivalent inductance, superior current handling (880 mA vs. 790 mA), lower DC resistance (192 mOhm vs. 284 mOhm), and compatible physical dimensions (3.00mm × 3.00mm footprint).

Parameter Comparison

Engineering Selection Recommendations

The NR3015T6R8M qualifies as a direct substitute for the ASPI-0316S-6R8N-T3 based on electrical and mechanical compatibility. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current and future applications.

The substitute part provides measurable performance improvements: 11% higher current rating (880 mA vs. 790 mA), 32% lower DC resistance (192 mOhm vs. 284 mOhm), and tighter inductance tolerance (±20% vs. ±30%). The extended operating temperature range (-25°C to 120°C vs. -25°C to 100°C) provides additional thermal margin.

The footprint reduction from 3.20mm to 3.00mm represents a minor dimensional change that may require PCB layout verification for existing designs. Height remains constant at 1.50mm, maintaining vertical clearance compatibility.

Frequently Asked Questions (FAQ)

Q: Can NR3015T6R8M be used as a direct replacement without circuit modification?

A: The NR3015T6R8M is electrically compatible as a substitute. The 6.8 µH inductance value, shielded ferrite core construction, and surface mount configuration match the original specification. The smaller footprint (3.00mm vs. 3.20mm) requires PCB layout verification to confirm pad spacing compatibility. Lower DC resistance and higher current rating represent performance improvements with no negative impact on circuit function.

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

A: Primary differences include inductance tolerance (±20% vs. ±30%), current rating (880 mA vs. 790 mA), DC resistance (192 mOhm vs. 284 mOhm), operating temperature range (-25°C to 120°C vs. -25°C to 100°C), and package footprint (3.00mm vs. 3.20mm). The substitute part provides superior electrical performance across all measured parameters.

Q: Are both parts compliant with current regulatory standards?

A: Both the ASPI-0316S-6R8N-T3 and NR3015T6R8M are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the product status difference?

A: The ASPI-0316S-6R8N-T3 is classified as obsolete, indicating discontinued manufacturing and limited availability. The NR3015T6R8M is marked as "Not For New Designs," indicating limited support but continued availability. For new production, neither part is recommended for initial design selection; however, the Taiyo Yuden part provides superior availability and performance characteristics for replacement applications.

Q: Does the lower DC resistance of the substitute part affect circuit behavior?

A: Lower DC resistance (192 mOhm vs. 284 mOhm) reduces resistive losses in the inductor, resulting in improved efficiency and reduced heat generation. This represents a performance enhancement with no adverse effects on circuit compatibility or function.
