Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0804T-150M-T is determined by the following critical parameters:

• Inductance Value: Must be 15 µH with ±20% tolerance
• Current Rating: Must meet or exceed 3 A continuous current
• DC Resistance: Must not exceed 46 mOhm to maintain equivalent power dissipation characteristics
• Core Material & Type: Ferrite drum core, unshielded construction
• Mounting & Package: Surface mount with compatible footprint dimensions (12.95mm x 9.40mm)
• Inductance Test Frequency: 100 kHz measurement standard
• Compliance: ROHS3 compliant, MSL 1 rating

The B82476A1153M000 from EPCOS - TDK Electronics meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The B82476A1153M000 is a direct substitute for the ASPI-0804T-150M-T based on electrical and mechanical compatibility. Both parts are ROHS3 compliant and carry MSL 1 ratings, meeting identical regulatory requirements. The substitute part offers improved electrical performance with lower DC resistance (40 mOhm vs. 46 mOhm) and higher current rating (3.1 A vs. 3 A), while maintaining identical inductance and tolerance specifications. The substitute's extended operating temperature range (-55°C to 150°C) provides additional thermal margin compared to the primary part (-40°C to 85°C). Physical dimensions are compatible with a marginal height reduction (5.08mm vs. 5.21mm), which presents no functional constraint for standard PCB layouts. Both parts are manufactured to the same 100 kHz inductance test frequency standard.

Frequently Asked Questions (FAQ)

Q: Can the B82476A1153M000 be used as a direct replacement for the ASPI-0804T-150M-T?

A: Yes. Both parts share identical inductance (15 µH ±20%), equivalent core construction (ferrite drum core, unshielded), and compatible surface mount packages with matching footprint dimensions. The substitute meets or exceeds all electrical specifications of the primary part.

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

A: The B82476A1153M000 provides superior electrical performance with lower DC resistance (40 mOhm vs. 46 mOhm) and higher current rating (3.1 A vs. 3 A). It also features an extended operating temperature range (-55°C to 150°C vs. -40°C to 85°C) and a marginally reduced seated height (5.08mm vs. 5.21mm).

Q: Are there any package compatibility concerns?

A: No. Both parts use identical footprint dimensions (12.95mm L x 9.40mm W). The substitute's reduced height (5.08mm vs. 5.21mm) presents no compatibility issues for standard PCB assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ASPI-0804T-150M-T and B82476A1153M000 are ROHS3 compliant with MSL 1 ratings and REACH unaffected status.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements and supply availability. The B82476A1153M000 is preferred when extended temperature operation or lower DC resistance is beneficial. The ASPI-0804T-150M-T remains suitable for applications within its specified temperature range with standard current requirements.
