ASPI-0315FSSA-220M-T3 Equivalent & Substitute Parts

Part Overview

The ASPI-0315FSSA-220M-T3 is a 22 µH shielded drum core wirewound inductor manufactured by Abracon LLC, rated for 470 mA continuous current with 500mOhm DC resistance. This component features a nickel zinc ferrite core in a nonstandard 3.00mm x 3.00mm surface mount package with 1.50mm maximum seated height. The part is currently obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0315FSSA-220M-T3 is determined by the following critical parameters:

Inductance value must remain 22 µH with ±20% tolerance to maintain circuit performance. The shielded drum core construction and surface mount configuration are mandatory for electromagnetic compatibility and PCB integration. The nonstandard 3.00mm x 3.00mm footprint with 1.50mm maximum height establishes the physical constraint for board-level placement.

Current rating and DC resistance are secondary selection criteria. The substitute part must support the application's current requirements while maintaining acceptable power dissipation characteristics. Operating temperature range and regulatory compliance (RoHS3, REACH Unaffected, EAR99) ensure functional reliability across specified environmental conditions.

The ASPI-0315FS-220M-T2 qualifies as a direct substitute based on matching inductance, tolerance, core shielding, package footprint, and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0315FS-220M-T2 is the qualified substitute for the obsolete ASPI-0315FSSA-220M-T3. Both components maintain identical inductance specifications, tolerance bands, and physical footprints required for direct PCB replacement.

The substitute part offers improved current rating capacity (570 mA versus 470 mA) and extended operating temperature range (-25°C ~ 120°C versus -30°C ~ 100°C), providing enhanced performance margins for thermal and electrical stress conditions. The active product status of the ASPI-0315FS-220M-T2 ensures long-term availability and supply chain continuity.

Both parts satisfy identical regulatory requirements: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level remains unchanged at MSL 1 (unlimited), maintaining equivalent handling and storage protocols.

DC resistance increases from 500mOhm to 598mOhm maximum, resulting in marginally higher power dissipation. Applications with strict power budget constraints require thermal analysis to confirm acceptable performance under maximum current conditions.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0315FS-220M-T2 replace the ASPI-0315FSSA-220M-T3 in existing designs?

A: Yes. Both components share identical inductance values (22 µH ±20%), shielded drum core construction, and nonstandard 3.00mm x 3.00mm surface mount footprint with 1.50mm maximum height. Physical and electrical compatibility is confirmed for direct PCB substitution.

Q: What are the differences in current handling between these parts?

A: The ASPI-0315FS-220M-T2 is rated for 570 mA continuous current compared to 470 mA for the ASPI-0315FSSA-220M-T3. This represents a 100 mA increase in current capacity, providing additional design margin for applications operating near the original part's current limit.

Q: How does the DC resistance difference affect circuit performance?

A: DC resistance increases from 500mOhm to 598mOhm maximum. This 98mOhm increase results in proportionally higher resistive losses. At 470 mA, the power dissipation difference is approximately 23 mW. Applications with thermal constraints require verification that this additional dissipation remains within acceptable limits.

Q: Are the operating temperature ranges compatible?

A: The ASPI-0315FS-220M-T2 supports -25°C ~ 120°C versus -30°C ~ 100°C for the original part. The substitute provides extended high-temperature capability (20°C additional margin) but slightly reduced low-temperature range (5°C). Applications operating below -25°C require confirmation that the original temperature specification is mandatory.

Q: What is the packaging difference between these parts?

A: The ASPI-0315FSSA-220M-T3 is supplied in standard packaging, while the ASPI-0315FS-220M-T2 is supplied in Tape & Reel (TR) format. Both maintain identical component dimensions and surface mount compatibility. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or PCB integration.

Q: Are regulatory certifications identical?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory and compliance requirements are fully equivalent.
