Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0804T-3R3M-T is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 3.3 µH (within ±20% tolerance specification)
• Current rating: minimum 6.4 A continuous
• DC resistance: maximum 15 mOhm
• Shielding configuration: unshielded
• Inductance test frequency: 100 kHz

Mechanical Compatibility Criteria:

• Mounting type: surface mount
• Physical footprint: 0.510" L x 0.370" W (12.95mm x 9.40mm)
• Height constraint: maximum 0.205" (5.21mm) seated height
• Package type: nonstandard

Compliance & Environmental Criteria:

• RoHS3 compliance required
• Moisture sensitivity level: 1 (unlimited)
• Operating temperature range: minimum -40°C ~ 85°C

The substitute part P0751.332NLT meets the inductance, shielding, mounting, footprint, and compliance requirements. Current rating and DC resistance parameters require evaluation against application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ASPI-0804T-3R3M-T and P0751.332NLT maintain active product status with full RoHS3 compliance and unlimited moisture sensitivity ratings, ensuring long-term availability and regulatory compliance for industrial applications.

The P0751.332NLT substitute provides identical inductance value and tolerance, matching footprint dimensions, and extended operating temperature range to 130°C. The substitute exhibits a continuous current rating of 5.4 A compared to the main part's 6.4 A rating, with saturation current specified at 6.4 A. DC resistance increases from 15 mOhm to 18 mOhm maximum. Physical height increases by 0.010" (0.25mm) to 0.215" maximum seated height.

Selection between these parts depends on application requirements for continuous current capacity and DC resistance losses. Both parts satisfy identical mechanical footprint and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can P0751.332NLT be used as a direct replacement for ASPI-0804T-3R3M-T?

A: Mechanical and electrical compatibility exists for applications where the continuous current requirement does not exceed 5.4 A and the additional 3 mOhm DC resistance is acceptable. The substitute provides identical inductance value, footprint, and compliance certifications. Physical height increases by 0.010" (0.25mm).

Q: What are the key differences between these inductors?

A: The primary differences are continuous current rating (6.4 A vs. 5.4 A), DC resistance (15 mOhm vs. 18 mOhm), and operating temperature range (-40°C ~ 85°C vs. -40°C ~ 130°C). Both parts share identical inductance value, tolerance, footprint dimensions, shielding configuration, and compliance status.

Q: Are both parts surface mount compatible?

A: Yes, both parts are surface mount inductors with identical footprint dimensions of 0.510" L x 0.370" W (12.95mm x 9.40mm), enabling direct PCB layout compatibility.

Q: Do both parts meet RoHS3 compliance requirements?

A: Yes, both ASPI-0804T-3R3M-T and P0751.332NLT are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: What is the inductance tolerance for both parts?

A: Both inductors specify ±20% inductance tolerance, measured at 100 kHz test frequency.
