Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0428S-5R6M-T is determined by the following critical parameters:

• Inductance Value: 5.6 µH (exact match required)
• Current Rating: 1.17 A (minimum threshold)
• DC Resistance: 100.9 mOhm maximum (electrical performance constraint)
• Core Material: Ferrite (electromagnetic characteristics)
• Shielding: Shielded (EMI containment requirement)
• Mounting Type: Surface Mount (assembly compatibility)
• Physical Dimensions: 0.185" L x 0.185" W, 0.118" height maximum (PCB layout constraint)
• Operating Temperature Range: -40°C ~ 85°C (thermal compatibility)
• Compliance Standards: ROHS3, REACH Unaffected (regulatory requirement)

The ASPI-0428S-5R6N-T qualifies as a direct substitute, maintaining all critical electrical and mechanical parameters while offering active product status and standard tape & reel packaging.

Engineering Selection Recommendations

The ASPI-0428S-5R6N-T is the qualified substitute for the obsolete ASPI-0428S-5R6M-T. Selection rationale is based on the following factors:

Product Status: The substitute part maintains active product status with Abracon LLC, ensuring continued availability and manufacturing support. The main part's obsolete classification creates supply risk for new production and long-term support.

Electrical Equivalence: Both parts maintain identical inductance (5.6 µH), current rating (1.17 A), and DC resistance (100.9 mOhm maximum). The substitute's inductance tolerance of ±30% remains within acceptable circuit design margins compared to the main part's ±20% tolerance.

Mechanical Compatibility: Identical physical dimensions (0.185" L x 0.185" W, 0.118" maximum height) and surface mount configuration ensure direct PCB layout compatibility without redesign requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and safety standards. ECCN classification (EAR99) remains unchanged.

Packaging Advantage: The substitute is supplied in standard tape & reel format, improving automated assembly efficiency compared to the main part's unspecified packaging format.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0428S-5R6N-T be used as a direct replacement without circuit modification?

A: Yes. The substitute maintains all critical electrical parameters (inductance, current rating, DC resistance) and identical physical dimensions. No circuit redesign is required for direct substitution in existing applications.

Q: What is the significance of the inductance tolerance difference (±20% vs ±30%)?

A: The main part specifies ±20% tolerance while the substitute specifies ±30%. For applications with tight inductance requirements, circuit performance must be evaluated against the wider tolerance band of the substitute part. Both tolerances are measured at 100 kHz test frequency.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C ~ 85°C) and maintain the same MSL rating of 1 (unlimited moisture sensitivity level), indicating equivalent environmental performance characteristics.

Q: Why is the substitute available in tape & reel packaging while the main part is not specified?

A: The substitute's tape & reel format is a standard packaging option for automated assembly processes. This represents an improvement in manufacturing efficiency and supply chain standardization, with no impact on electrical or mechanical performance.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the ASPI-0428S-5R6M-T and ASPI-0428S-5R6N-T maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and safety regulations.
