Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0615FS-6R8M-T2 is determined by the following critical parameters:

Inductance Value: Must be 6.8 µH within ±20% tolerance
Current Rating: Must support minimum 1.8 A continuous operation
DC Resistance: Must not exceed 60mOhm to maintain thermal and efficiency characteristics
Core Type: Ferrite drum core construction required for shielding performance
Shielding: Shielded configuration mandatory
Package Compatibility: Nonstandard surface mount package with compatible footprint dimensions
Compliance: ROHS3 compliance required; REACH unaffected status maintained

The B82462G4682M000 from EPCOS - TDK Electronics meets these substitution criteria with equivalent inductance, shielded ferrite construction, and superior DC resistance specification (50mOhm maximum versus 60mOhm).

Engineering Selection Recommendations

Primary Part: ASPI-0615FS-6R8M-T2

Select the primary part when current requirements reach 1.8 A and saturation margin is critical. This part provides the specified performance envelope with established supply availability exceeding 1,200 units.

Substitute Part: B82462G4682M000

The B82462G4682M000 qualifies as a manufacturer-recommended substitute when the following conditions are met:

Application current does not exceed 1.65 A continuous operation
Saturation margin of 1.5 A is acceptable for the circuit design
PCB layout accommodates the increased height of 3.00mm (versus 2.20mm)
Footprint tolerance permits the 6.30mm x 6.30mm package versus 6.00mm x 6.00mm
Extended operating temperature range (-55°C to 150°C) provides additional environmental margin
AEC-Q200 automotive qualification is beneficial for reliability-critical applications

Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and REACH unaffected status. The substitute part offers superior DC resistance specification (50mOhm maximum) and wider temperature operating range, offsetting the lower current and saturation ratings.

Frequently Asked Questions (FAQ)

Q: Can B82462G4682M000 be used as a direct replacement for ASPI-0615FS-6R8M-T2?

A: Substitution is valid only when application current remains below 1.65 A. The substitute part has lower current rating (1.65 A versus 1.8 A) and lower saturation current (1.5 A versus 2.0 A). Verify circuit current requirements before substitution.

Q: What are the physical differences between these parts?

A: The substitute part (B82462G4682M000) is larger in both footprint and height. Footprint increases from 6.00mm x 6.00mm to 6.30mm x 6.30mm, and height increases from 2.20mm to 3.00mm. PCB layout must accommodate these dimensional changes.

Q: Are both parts RoHS compliant?

A: Yes, both ASPI-0615FS-6R8M-T2 and B82462G4682M000 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the inductance tolerance for both parts?

A: Both parts specify ±20% inductance tolerance at 100 kHz test frequency. Actual inductance values may vary within this range.

Q: Does the substitute part have automotive qualification?

A: Yes, B82462G4682M000 carries AEC-Q200 automotive qualification, whereas ASPI-0615FS-6R8M-T2 does not list this certification.

Q: Which part has better DC resistance performance?

A: B82462G4682M000 specifies 50mOhm maximum DC resistance, compared to 60mOhm for ASPI-0615FS-6R8M-T2. Lower DC resistance reduces resistive losses and heat generation.

Q: Can these parts be used in high-temperature applications?

A: B82462G4682M000 supports -55°C to 150°C operating range, providing wider temperature margin than ASPI-0615FS-6R8M-T2 (-25°C to 120°C). Select the substitute part for extended temperature requirements.
