Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASPIAIG-S8050-1R5M-T is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 1.5 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Core material: Nickel Zinc Ferrite (NiZn)
• Mounting type: Surface Mount
• Package footprint: 8.00mm x 8.00mm

Performance Parameters (Must Meet or Exceed):

• Current rating: Minimum 6.5 A
• Saturation current: Minimum 13 A
• DC resistance: Maximum 12mOhm
• Operating temperature range: Must include -40°C to 125°C

Compliance Requirements:

• AEC-Q200 automotive qualification
• RoHS3 compliance
• Surface mount packaging (Tape & Reel)

The SDCHA1V8040-1R5-R qualifies as a substitute based on matching inductance, core material, package footprint, and compliance certifications while providing improved current handling and lower DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The SDCHA1V8040-1R5-R from Eaton - Electronics Division is qualified as a substitute for the ASPIAIG-S8050-1R5M-T based on the following engineering criteria:

Electrical Equivalence: Both parts maintain identical 1.5 µH inductance at 100 kHz with ±20% tolerance and NiZn ferrite core construction. The substitute provides superior continuous current rating (8.0 A vs. 6.5 A) and lower DC resistance (10mOhm vs. 12mOhm), resulting in reduced power dissipation in the application circuit.

Compliance & Qualification: Both components carry AEC-Q200 automotive qualification, confirming suitability for automotive and industrial applications. Both maintain MSL Level 1 (Unlimited) moisture sensitivity rating, eliminating moisture-related handling constraints.

Physical Compatibility: Identical 8.00mm x 8.00mm footprint ensures direct PCB layout compatibility. The substitute's reduced height (4.00mm vs. 5.20mm) provides additional board clearance without requiring design modification.

Temperature Performance: The substitute's extended operating range (-55°C to 125°C vs. -40°C to 125°C) accommodates wider environmental conditions while maintaining the original specification minimum of -40°C to 125°C.

Considerations: The substitute employs semi-shielded construction versus the main part's fully shielded design. This difference may affect electromagnetic interference characteristics in noise-sensitive applications. The substitute's lower saturation current (11.5 A vs. 13 A) remains above the main part's 6.5 A continuous rating but provides reduced margin above continuous operation. Self-resonant frequency is lower (66 MHz vs. 79 MHz), which may impact high-frequency performance in specific circuit topologies.

Frequently Asked Questions (FAQ)

Q: Can the SDCHA1V8040-1R5-R directly replace the ASPIAIG-S8050-1R5M-T in existing designs?

A: Direct PCB replacement is possible due to matching 8.00mm x 8.00mm footprint and identical inductance specification. However, circuit validation is necessary to confirm compatibility with shielding requirements and saturation current margins specific to your application.

Q: What is the difference between shielded and semi-shielded inductors?

A: Shielded inductors (ASPIAIG-S8050-1R5M-T) provide complete magnetic field containment, minimizing electromagnetic interference with adjacent components. Semi-shielded inductors (SDCHA1V8040-1R5-R) offer partial field containment with reduced shielding effectiveness but typically lower profile and cost. Selection depends on EMI requirements in your circuit layout.

Q: Does the lower saturation current of the substitute affect performance?

A: The substitute's 11.5 A saturation current remains 1.77 times higher than the main part's 6.5 A continuous rating, providing adequate margin for transient current conditions. However, if your application requires saturation current headroom exceeding 11.5 A, the main part's 13 A specification is necessary.

Q: Are both parts available in the same packaging format?

A: Yes, both components are supplied in Tape & Reel (TR) surface mount packaging suitable for automated assembly processes. Identical MSL Level 1 rating eliminates moisture sensitivity handling differences.

Q: What is the impact of the substitute's lower DC resistance?

A: Lower DC resistance (10mOhm vs. 12mOhm) reduces resistive power loss by approximately 17% at rated current, resulting in lower operating temperature and improved efficiency. This is a performance advantage with no negative impact on circuit function.

Q: How do the self-resonant frequencies compare?

A: The main part's 79 MHz self-resonant frequency is higher than the substitute's 66 MHz. In applications operating near or above 66 MHz, the substitute's lower self-resonant frequency may alter impedance characteristics. Frequency-dependent circuit analysis is recommended for high-frequency applications.

Q: Is RoHS3 compliance confirmed for the substitute?

A: RoHS3 compliance status is not specified in the substitute part documentation. Verification with Eaton - Electronics Division is recommended if RoHS3 certification is a mandatory requirement for your application or supply chain.
