Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-0428S-8R2M-T is determined by the following critical parameters:

• Inductance Value: 8.2 µH (primary electrical specification)
• Current Rating: 1.04 A minimum (thermal and saturation performance)
• DC Resistance: 117.5 mOhm maximum (power loss and thermal characteristics)
• Core Material: Ferrite (electromagnetic performance and frequency response)
• Shielding: Shielded configuration (EMI containment requirements)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Physical Dimensions: 0.185" L x 0.185" W x 0.118" H (board layout constraints)
• Operating Temperature Range: -40°C to 85°C (environmental specifications)
• Compliance Standards: ROHS3, REACH Unaffected (regulatory requirements)

The ASPI-0428S-8R2N-T meets all substitution criteria as an active product within the same series, maintaining identical electrical performance and physical form factor while offering improved supply availability.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0428S-8R2N-T is the direct substitute for the obsolete ASPI-0428S-8R2M-T. Both components are manufactured by Abracon LLC within the same product series and maintain identical electrical specifications and physical dimensions.

The substitute part offers the following advantages:

• Active Product Status: The ASPI-0428S-8R2N-T is currently in active production, ensuring long-term supply chain availability and support.
• Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying current environmental and regulatory requirements.
• Packaging Optimization: The substitute is supplied in Tape & Reel format, which is standard for automated assembly processes and reduces handling costs compared to bulk packaging.

The inductance tolerance difference (±20% vs. ±30%) should be evaluated against circuit design margins. If the original ±20% tolerance is critical to circuit performance, this parameter must be confirmed within the application's acceptable range.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0428S-8R2N-T be used as a direct replacement for the ASPI-0428S-8R2M-T?

A: Yes. Both parts share identical inductance values (8.2 µH), current ratings (1.04 A), DC resistance specifications (117.5 mOhm max), core materials (ferrite), shielding configurations, mounting types (surface mount), and physical dimensions (0.185" x 0.185" x 0.118"). The substitute is manufactured by the same supplier and maintains the same operating temperature range and compliance certifications.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The ASPI-0428S-8R2M-T is obsolete and supplied in bulk packaging, while the ASPI-0428S-8R2N-T is an active product supplied in Tape & Reel format. Additionally, the inductance tolerance specification differs: ±20% for the original part versus ±30% for the substitute.

Q: Does the inductance tolerance difference affect compatibility?

A: The inductance tolerance difference (±20% vs. ±30%) must be evaluated within the context of your circuit design. If the application requires the tighter ±20% tolerance for proper operation, this parameter should be confirmed as acceptable before implementation. If your design accommodates ±30% tolerance, the substitute part is fully compatible.

Q: Is the Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. If your manufacturing process uses automated pick-and-place equipment, this packaging format is compatible. If your process requires bulk or alternative packaging, contact your supplier for packaging options.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance and REACH Unaffected status. There are no differences in regulatory certifications or environmental compliance between the two parts.
