AISC-1210H-8R2N-T Equivalent & Substitute Parts

Part Overview

The AISC-1210H-8R2N-T is an 8.2 µH unshielded drum core wirewound inductor manufactured by Abracon LLC, rated for 700 mA continuous current with a maximum DC resistance of 450mOhm. This component is designed for surface mount applications in the 1210 (3225 Metric) package format.

The AISC-1210H-8R2N-T is classified as obsolete. Equivalent substitute parts are necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution eligibility for the AISC-1210H-8R2N-T is determined by the following critical parameters:

• Inductance value: 8.2 µH (exact match required)
• Package format: 1210 (3225 Metric) surface mount
• Core type: Drum core, wirewound ferrite
• Current handling capability: minimum 700 mA
• DC resistance: maximum 450mOhm
• Environmental compliance: ROHS3 compliant

The SP1210R-822K from API Delevan Inc. meets the inductance, package, core type, and compliance requirements. However, the substitute exhibits reduced current rating (487 mA versus 700 mA) and increased DC resistance (880mOhm versus 450mOhm maximum). These differences must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The SP1210R-822K is an active product from API Delevan Inc. and represents the primary substitute for the obsolete AISC-1210H-8R2N-T. Both components are ROHS3 compliant and utilize identical package formats for direct PCB footprint compatibility.

Selection of the SP1210R-822K requires circuit-level validation due to the following parameter deviations: current rating reduction from 700 mA to 487 mA, DC resistance increase from 450mOhm to 880mOhm maximum, and shielding configuration change from unshielded to shielded. The substitute offers improved inductance tolerance (±10% versus ±30%) and extended operating temperature range (-55°C ~ 125°C versus -25°C ~ 85°C).

Frequently Asked Questions (FAQ)

Q: Can the SP1210R-822K directly replace the AISC-1210H-8R2N-T in all applications?

A: Direct replacement requires verification that circuit current requirements do not exceed 487 mA and that the increased DC resistance of 880mOhm does not degrade circuit performance. The shielded configuration of the substitute may affect electromagnetic coupling in sensitive circuits.

Q: What is the impact of the inductance tolerance difference?

A: The AISC-1210H-8R2N-T specifies ±30% tolerance, while the SP1210R-822K specifies ±10% tolerance. The substitute provides tighter inductance control, which may improve circuit performance in applications sensitive to inductance variation.

Q: Are both components compatible with the same PCB footprint?

A: Yes. Both components use the 1210 (3225 Metric) surface mount package format. Physical dimensions are comparable: AISC-1210H-8R2N-T measures 4.60mm L x 2.50mm W x 2.50mm H (max), while SP1210R-822K measures 3.25mm L x 2.42mm W x 2.57mm H (max).

Q: What is the significance of the shielding difference?

A: The AISC-1210H-8R2N-T is unshielded, while the SP1210R-822K is shielded. Shielding reduces electromagnetic radiation and susceptibility to external fields. Circuit design must account for this configuration change, particularly in high-frequency or noise-sensitive applications.

Q: Are there compliance or regulatory differences between these components?

A: Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No regulatory barriers exist to substitution from a compliance perspective.
