Substitute Part Grouping Explanation

Substitute parts for the ASPI-0804T-2R2M-T are qualified based on the following criteria:

Electrical Equivalence Requirements:

• Inductance value: 2.2 µH with ±20% tolerance
• DC resistance: 12 mOhm maximum
• Current rating: minimum 5.7 A (acceptable for applications where the main part's 7 A rating provides design margin)
• Inductance measurement frequency: 100 kHz

Mechanical & Environmental Compatibility:

• Surface mount package configuration
• Unshielded wirewound construction
• Operating temperature range overlap with -40°C minimum
• RoHS3 compliance maintained

Regulatory & Compliance:

• REACH Unaffected status
• Moisture sensitivity level MSL 1 (Unlimited)

Two substitute parts meet these criteria: B82464A4222M000 (EPCOS - TDK Electronics) and P0751.222NL (Pulse Electronics). Both maintain the core electrical specifications while offering alternative sourcing options.

Parameter Comparison

Engineering Selection Recommendations

B82464A4222M000 (EPCOS - TDK Electronics): This substitute maintains identical inductance and DC resistance specifications with a current rating of 5.7 A. The part carries AEC-Q200 automotive qualification, indicating enhanced reliability screening. The extended operating temperature range (-55°C ~ 150°C) provides thermal margin beyond the main part. Drum core construction matches the original design. This substitute is suitable for applications where the 7 A rating of the main part includes design margin and the application current does not exceed 5.7 A.

P0751.222NL (Pulse Electronics): This substitute maintains the 2.2 µH inductance with a current rating of 6.1 A and operating temperature range of -40°C ~ 130°C. DC resistance is specified at 15 mOhm maximum, representing a 25% increase over the main part. Physical dimensions match the original (0.510" L x 0.370" W). This substitute is suitable for applications where the slightly elevated DC resistance is acceptable and current requirements do not exceed 6.1 A.

Both substitutes maintain Active product status, full RoHS3 compliance, and REACH Unaffected designation, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can B82464A4222M000 be used in place of ASPI-0804T-2R2M-T in all applications?

A: B82464A4222M000 is electrically equivalent for inductance and DC resistance. However, its current rating is 5.7 A compared to the main part's 7 A. Substitution is valid only when the application current requirement does not exceed 5.7 A. If the design operates at or near 7 A, the main part or P0751.222NL should be used.

Q: What is the impact of the higher DC resistance in P0751.222NL?

A: P0751.222NL specifies 15 mOhm maximum DC resistance versus 12 mOhm for the main part. This 3 mOhm difference results in increased resistive losses proportional to the square of the current. At 6 A, the additional loss is approximately 108 mW compared to the main part at the same current. This is acceptable in applications where thermal dissipation is not critical.

Q: Are the physical dimensions compatible across all three parts?

A: ASPI-0804T-2R2M-T and P0751.222NL share identical footprint dimensions (0.510" L x 0.370" W). B82464A4222M000 has a smaller footprint (0.409" L x 0.409" W). Both substitutes are surface mount compatible, but PCB layout verification is required when changing from the main part to B82464A4222M000 due to dimensional differences.

Q: Do all three parts meet the same compliance standards?

A: All three parts are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. B82464A4222M000 additionally carries AEC-Q200 automotive qualification. All parts are Active status with unlimited shelf life under MSL 1 conditions.

Q: What is the operating temperature consideration for substitution?

A: The main part operates -40°C ~ 85°C. B82464A4222M000 extends to -55°C ~ 150°C, and P0751.222NL to -40°C ~ 130°C. Both substitutes provide equal or superior temperature range coverage. If the application operates above 85°C, either substitute is required.
