Substitute Part Grouping Explanation

Substitution of the AISC-1210H-180K-T is determined by the following critical parameters:

• Inductance value: 18 µH (exact match required)
• Tolerance: ±10% (matching tolerance specification)
• Package / Case: 1210 (3225 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Material - Core: Ferrite (electrical performance characteristics)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

The substitute part SP1210R-183K meets the core inductance and package requirements. However, differences in current rating, DC resistance, shielding configuration, and operating temperature range must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The SP1210R-183K is an active product from API Delevan Inc. and maintains ROHS3 compliance, providing regulatory continuity for replacement applications. Both components share identical inductance values, tolerance specifications, and 1210 (3225 Metric) package form factors, ensuring physical and electrical compatibility at the circuit board level.

The SP1210R-183K operates across an extended temperature range (-55°C to 125°C) compared to the AISC-1210H-180K-T (-25°C to 85°C), providing broader environmental coverage. The substitute part incorporates shielding, which may alter electromagnetic coupling characteristics in the circuit compared to the unshielded original design.

Current rating differences must be evaluated: the AISC-1210H-180K-T supports 450 mA, while the SP1210R-183K is rated for 322 mA. DC resistance differs significantly (978mOhm versus 2Ohm maximum), which affects power dissipation and circuit performance. These parameter variations require circuit-level validation to confirm functional equivalence in the target application.

Frequently Asked Questions (FAQ)

Q: Can SP1210R-183K directly replace AISC-1210H-180K-T in all applications?

A: Both components share the same inductance value (18 µH), tolerance (±10%), and 1210 (3225 Metric) package. However, differences in current rating (322 mA vs. 450 mA), DC resistance (2Ohm vs. 978mOhm), and shielding configuration require application-specific validation. Current and thermal performance must be confirmed for your circuit design.

Q: What is the impact of shielding differences?

A: The AISC-1210H-180K-T is unshielded, while the SP1210R-183K is shielded. Shielding reduces electromagnetic radiation and susceptibility to external fields. In circuits sensitive to EMI/RFI, the shielded substitute may alter coupling behavior. In noise-critical applications, shielding may provide performance benefits.

Q: Are both components RoHS compliant?

A: Yes, both the AISC-1210H-180K-T and SP1210R-183K are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What is the temperature operating range difference?

A: The AISC-1210H-180K-T operates from -25°C to 85°C, while the SP1210R-183K operates from -55°C to 125°C. The substitute provides extended low and high temperature capability, suitable for applications requiring broader environmental performance.

Q: How do DC resistance values affect circuit performance?

A: The AISC-1210H-180K-T has a maximum DCR of 978mOhm, while the SP1210R-183K has a maximum DCR of 2Ohm. Higher DC resistance increases power dissipation and may affect circuit efficiency and thermal management. Applications with strict power budget requirements must account for this difference.
