ASPI-0804T-101M-T Equivalent & Substitute Parts

Part Overview

The ASPI-0804T-101M-T is a 100 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 1.2 A continuous current with a maximum DC resistance of 280mOhm. 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 676 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to component availability, supply chain considerations, or design flexibility within the allowed parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0804T-101M-T is determined by the following critical parameters:

• Inductance value of 100 µH within ±20% tolerance
• Current rating of 1.2 A or greater
• DC resistance not exceeding 280mOhm maximum
• Ferrite drum core construction, unshielded configuration
• Surface mount package type
• Operating temperature range of -40°C to 85°C minimum
• ROHS3 compliance and MSL 1 rating

The substitute part UP2B-101-R from Eaton - Electronics Division meets all these criteria, maintaining identical inductance, current rating, and core material specifications while operating within the same temperature envelope and compliance framework.

Parameter Comparison

Engineering Selection Recommendations

Both the ASPI-0804T-101M-T and UP2B-101-R are active production components with full ROHS3 compliance and REACH unaffected status. The UP2B-101-R offers a marginal advantage in DC resistance specification at 270.7mOhm maximum compared to 280mOhm maximum, resulting in lower power dissipation under identical current conditions. Both components maintain identical electrical performance across the specified operating temperature range and inductance test frequency. Selection between these parts should be based on availability, lead time, and packaging requirements specific to your supply chain.

Frequently Asked Questions (FAQ)

Q: Can UP2B-101-R replace ASPI-0804T-101M-T in existing designs?

A: Yes. Both components share identical inductance values, current ratings, core materials, and operating temperature ranges. The UP2B-101-R exhibits lower DC resistance, which is electrically favorable. Both are surface mount components with equivalent moisture sensitivity ratings.

Q: Are there physical dimension differences between these parts?

A: Yes. The ASPI-0804T-101M-T measures 0.510" L x 0.370" W x 0.205" H (12.95mm x 9.40mm x 5.21mm), while the UP2B-101-R measures 0.550" L x 0.410" W x 0.236" H (13.97mm x 10.41mm x 6.00mm). PCB layout and clearance verification is required before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99.

Q: What is the saturation current specification for these inductors?

A: The ASPI-0804T-101M-T does not specify saturation current. The UP2B-101-R specifies 950mA saturation current, which exceeds the 1.2 A continuous current rating and indicates adequate margin for transient current conditions.
