ASPI-0804T-331M-T Equivalent & Substitute Parts

Part Overview

The ASPI-0804T-331M-T is a 330 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 600 mA continuous current with a maximum DC resistance of 1.02Ohm. This surface mount component operates across the temperature range of -40°C to 85°C and is ROHS3 compliant. The part is currently active in production with 885 pieces available in new original stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the critical parameters that define inductor functionality and board integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0804T-331M-T is determined by strict equivalence across the following critical parameters:

Inductance value and tolerance must match exactly at 330 µH ±20%. Current rating must be rated for minimum 600 mA continuous operation. DC resistance must not exceed 1.02Ohm maximum. Shielding configuration must remain unshielded to maintain electromagnetic compatibility with the original design. Physical dimensions must be identical at 0.510" L x 0.370" W to ensure PCB footprint compatibility. Surface mount mounting type is required for assembly process compatibility. Operating temperature range must encompass the minimum specification of -40°C to 85°C. RoHS3 compliance and MSL 1 rating must be maintained for regulatory and manufacturing requirements.

The P0752.334NLT from Pulse Electronics meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P0752.334NLT is an active production equivalent suitable for direct substitution in applications currently specified for the ASPI-0804T-331M-T. Both components maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory requirements for manufacturing and environmental standards.

The P0752.334NLT offers an extended operating temperature range of -40°C to 130°C compared to the ASPI-0804T-331M-T range of -40°C to 85°C, providing additional thermal margin in applications operating at elevated temperatures. The seated height difference of 0.215" (5.46mm) versus 0.205" (5.21mm) represents a 1mm increase and must be verified against PCB clearance constraints in designs with height-critical layouts.

Packaging format differs between the two parts: the ASPI-0804T-331M-T is supplied in Cut Tape format while the P0752.334NLT is supplied in Tape & Reel format. This distinction affects procurement and assembly line integration but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the P0752.334NLT replace the ASPI-0804T-331M-T in existing designs?

A: Yes. The P0752.334NLT meets all critical electrical and mechanical parameters required for direct substitution, including inductance value, current rating, DC resistance, physical dimensions, and compliance certifications.

Q: What is the significance of the 1mm height difference between these parts?

A: The P0752.334NLT has a maximum seated height of 0.215" (5.46mm) compared to 0.205" (5.21mm) for the ASPI-0804T-331M-T. This 1mm difference must be evaluated against PCB clearance requirements, particularly in designs with limited vertical space or components mounted on both sides of the board.

Q: Does the extended temperature range of the P0752.334NLT affect compatibility?

A: No. The P0752.334NLT operating range of -40°C to 130°C encompasses the ASPI-0804T-331M-T specification of -40°C to 85°C. Extended temperature capability does not compromise compatibility and may provide additional design margin for thermal stress conditions.

Q: Are there packaging considerations when switching between these parts?

A: Yes. The ASPI-0804T-331M-T is supplied in Cut Tape packaging while the P0752.334NLT is supplied in Tape & Reel packaging. Assembly line equipment and procurement processes must be configured accordingly, but electrical and mechanical performance remain equivalent.

Q: What parameters must remain constant for substitution eligibility?

A: Inductance value (330 µH), inductance tolerance (±20%), current rating (600 mA minimum), DC resistance (1.02Ohm maximum), shielding configuration (unshielded), physical footprint dimensions (0.510" x 0.370"), and compliance certifications (ROHS3, MSL 1) must all be maintained for valid substitution.
