Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0312FSSA-6R8M-T4 is determined by the following critical parameters:

Inductance value must remain 6.8 µH with ±20% tolerance to maintain circuit performance. Current rating and saturation current must meet or exceed the original specification of 800 mA continuous operation. DC resistance must not exceed 210 mOhm to preserve power efficiency characteristics. The component must maintain shielded construction and surface mount configuration with identical 3.00mm x 3.00mm footprint and 1.20mm maximum seated height for PCB compatibility. Operating temperature range must encompass the original -30°C to 100°C specification. RoHS3 compliance and MSL rating must be maintained for manufacturing and environmental standards.

The ASPI-0312FS-6R8M-T2 qualifies as a direct substitute based on matching inductance, identical physical dimensions, equivalent shielding, and compatible electrical parameters within acceptable tolerances.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0312FS-6R8M-T2 is the designated active equivalent for the obsolete ASPI-0312FSSA-6R8M-T4. Both components are manufactured by Abracon LLC and maintain ROHS3 compliance and REACH unaffected status. The substitute part provides improved DC resistance (190 mOhm versus 210 mOhm), reducing power dissipation. The operating temperature range of the substitute extends to 120°C, providing broader thermal coverage than the original -30°C to 100°C specification.

The current rating differential (740 mA versus 800 mA) and saturation current reduction (670 mA versus 840 mA) require circuit-level evaluation to confirm suitability for specific applications. The substitute is available in standard Tape & Reel packaging, improving supply chain accessibility compared to the nonstandard packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0312FS-6R8M-T2 be used as a direct replacement for the ASPI-0312FSSA-6R8M-T4?

A: The ASPI-0312FS-6R8M-T2 qualifies as a substitute based on matching inductance value, identical physical dimensions, equivalent shielding, and compatible electrical characteristics. However, the reduced current rating (740 mA versus 800 mA) and saturation current (670 mA versus 840 mA) must be evaluated against circuit requirements before implementation.

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

A: The primary differences are product status (obsolete versus active), current ratings, saturation current specifications, core material designation, packaging format, and operating temperature range. The substitute offers lower DC resistance and extended temperature capability.

Q: Are both parts physically compatible on the same PCB?

A: Yes. Both components share identical footprint dimensions (3.00mm x 3.00mm) and maximum seated height (1.20mm), ensuring mechanical compatibility with existing PCB layouts.

Q: What compliance certifications apply to the substitute part?

A: The ASPI-0312FS-6R8M-T2 maintains ROHS3 compliance, REACH unaffected status, and MSL rating appropriate for surface mount assembly processes.

Q: Why is the substitute part available in Tape & Reel packaging?

A: Standard Tape & Reel packaging improves manufacturing efficiency and supply chain logistics for active production parts, contrasting with the nonstandard packaging of the obsolete original component.
