Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASPI-0310FSSA-6R8M-T4 is determined by the following critical parameters:

Electrical Parameters:

• Inductance value: 6.8 µH (fixed requirement)
• Inductance tolerance: ±20% (acceptable range)
• Core material: Nickel Zinc Ferrite (NiZn) shielded drum core
• Shielding: Shielded configuration required

Current Handling:

• Current rating must meet or exceed 700 mA continuous operation
• Saturation current (Isat) must support the application's peak current demands
• DC resistance (DCR) should be minimized to reduce power dissipation

Physical & Mechanical Parameters:

• Mounting type: Surface Mount (SMD)
• Package dimensions: 3.00mm x 3.00mm footprint with 1.00mm maximum height
• Nonstandard package classification

Environmental & Compliance:

• Operating temperature range compatibility
• RoHS3 compliance requirement
• MSL rating of 1 (Unlimited moisture sensitivity)
• REACH compliance status

The substitute part ASPI-0310FS-6R8M-T2 maintains electrical equivalence through identical inductance, tolerance, core material, and shielding configuration while providing enhanced current handling capability and improved DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0310FS-6R8M-T2 is the direct substitute for the obsolete ASPI-0310FSSA-6R8M-T4. Selection is supported by the following factors:

Product Status: The substitute part maintains Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete classification of the main part.

Electrical Equivalence: Both parts share identical inductance value (6.8 µH), tolerance (±20%), core material (Nickel Zinc Ferrite), and shielding configuration. The substitute provides enhanced current handling (1.3 A versus 700 mA) and improved saturation current (700 mA versus 630 mA), making it suitable for applications requiring the original 700 mA rating.

DC Resistance Improvement: The substitute exhibits lower DC resistance (260 mOhm versus 300 mOhm), reducing power dissipation and improving thermal performance in the application circuit.

Compliance & Certifications: Both parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and REACH Unaffected status, meeting regulatory requirements for equivalent component selection.

Physical Compatibility: Identical footprint dimensions (3.00mm x 3.00mm) and maximum seated height (1.00mm) ensure direct PCB layout compatibility without design modification.

Temperature Range: The substitute supports an extended operating temperature range (-25°C ~ 120°C versus -30°C ~ 100°C), providing broader environmental operating capability.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0310FS-6R8M-T2 directly replace the ASPI-0310FSSA-6R8M-T4 without PCB modification?

A: Yes. Both parts share identical physical dimensions (3.00mm x 3.00mm footprint, 1.00mm maximum height) and mounting type (Surface Mount). No PCB layout changes are required for direct substitution.

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

A: The substitute part provides higher current rating (1.3 A versus 700 mA), higher saturation current (700 mA versus 630 mA), and lower DC resistance (260 mOhm versus 300 mOhm). Inductance value, tolerance, core material, and shielding remain identical.

Q: Why is the main part classified as Obsolete?

A: The ASPI-0310FSSA-6R8M-T4 is no longer in active production. The ASPI-0310FS-6R8M-T2 represents the current active equivalent from Abracon LLC.

Q: Are there compliance or certification differences between these parts?

A: No. Both parts maintain identical compliance status: ROHS3 Compliant, MSL 1 (Unlimited), and REACH Unaffected.

Q: What is the difference in packaging between these two parts?

A: The main part packaging is not specified. The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount component distribution.

Q: Does the extended temperature range of the substitute affect compatibility?

A: No. The substitute's extended operating temperature range (-25°C ~ 120°C versus -30°C ~ 100°C) is a superset of the original specification, ensuring compatibility across all original application temperature requirements.

Q: Are the inductance test frequencies identical?

A: Yes. Both parts are tested at 100 kHz inductance frequency, ensuring consistent measurement and performance characterization.
