Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0315FS-6R8M-T2 is determined by the following criteria:

Primary Matching Parameters:

• Inductance value: 6.8 µH
• Inductance tolerance: ±20%
• Physical package dimensions: 3.00mm x 3.00mm footprint
• Core material: Ferrite
• Mounting type: Surface Mount

Allowable Variations:

• Current rating: Substitute must meet or exceed 850 mA minimum
• DC resistance: Substitute must not exceed 260 mOhm maximum
• Shielding type: Semi-shielded or fully shielded configurations acceptable
• Operating temperature range: Substitute must cover or exceed -25°C ~ 120°C
• Self-resonant frequency: Substitute must operate within acceptable RF characteristics

The SRN3015C-6R8M qualifies as a direct substitute based on matching inductance, tolerance, core material, package footprint, and surface mount configuration.

Parameter Comparison

Engineering Selection Recommendations

The SRN3015C-6R8M from Bourns Inc. is qualified as a direct substitute for the ASPI-0315FS-6R8M-T2. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility. The substitute provides improved electrical performance with lower DC resistance (206 mOhm vs. 260 mOhm) and higher current capacity (1.7 A vs. 850 mA), supporting applications with increased thermal or current margin requirements. The extended operating temperature range (-55°C ~ 125°C) accommodates broader environmental specifications. The transition from fully shielded to semi-shielded configuration requires electromagnetic compatibility assessment for applications with strict EMI/RFI isolation requirements. Both components share identical package footprints and inductance specifications, enabling direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SRN3015C-6R8M replace the ASPI-0315FS-6R8M-T2 in all applications?

A: The SRN3015C-6R8M qualifies as a substitute based on matching inductance (6.8 µH), tolerance (±20%), core material (ferrite), and package dimensions (3.00mm x 3.00mm). The primary consideration is the shielding difference: the original part is fully shielded while the substitute is semi-shielded. Applications requiring complete electromagnetic isolation may require additional shielding evaluation.

Q: What are the electrical advantages of the substitute part?

A: The SRN3015C-6R8M provides lower DC resistance (206 mOhm maximum vs. 260 mOhm) and higher current rating (1.7 A vs. 850 mA). These characteristics reduce power dissipation and support higher current applications within the same package footprint.

Q: Are there temperature range differences?

A: Yes. The ASPI-0315FS-6R8M-T2 operates from -25°C to 120°C, while the SRN3015C-6R8M operates from -55°C to 125°C. The substitute supports extended low-temperature operation and slightly higher maximum temperature capability.

Q: Do both parts have identical PCB footprints?

A: Yes. Both components share identical package dimensions of 3.00mm x 3.00mm x 1.50mm (height seated maximum), enabling direct PCB layout compatibility without redesign.

Q: What compliance certifications apply to both parts?

A: Both the ASPI-0315FS-6R8M-T2 and SRN3015C-6R8M maintain ROHS3 compliance, REACH unaffected status, and moisture sensitivity level 1 (unlimited). Both are classified under ECCN EAR99 and HTSUS 8504.50.4000.

Q: How do the self-resonant frequencies compare?

A: The ASPI-0315FS-6R8M-T2 has a self-resonant frequency of 39 MHz, while the SRN3015C-6R8M operates at 36 MHz. Both values support similar RF performance characteristics for typical inductor applications.
