Substitute Part Grouping Explanation

Substitution eligibility for the AISC-1210H-4R7N-T is determined by the following critical parameters:

• Inductance Value: 4.7 µH (exact match required)
• Current Rating: 900 mA minimum
• Package Format: 1210 (3225 Metric) surface mount
• Core Type: Ferrite drum core, wirewound, unshielded
• DC Resistance: Maximum 247mOhm or lower
• Compliance: ROHS3 compliant

The NLCV32T-4R7M-EFR from TDK Corporation meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The NLCV32T-4R7M-EFR is the qualified substitute for the AISC-1210H-4R7N-T. Selection is based on the following factors:

• Electrical Equivalence: Both components provide identical inductance (4.7 µH) and current rating (900 mA) with compatible DC resistance specifications.
• Package Compatibility: Both use the 1210 (3225 Metric) surface mount package, ensuring mechanical and thermal compatibility with existing PCB layouts.
• Compliance Status: Both components are ROHS3 compliant with MSL 1 rating, meeting regulatory and environmental requirements.
• Product Availability: The TDK substitute is active in production, providing long-term supply continuity compared to the obsolete Abracon part.
• Enhanced Operating Range: The TDK component supports an extended operating temperature range (-40°C ~ 105°C) compared to the original (-25°C ~ 85°C), offering greater thermal margin in demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the NLCV32T-4R7M-EFR be used as a direct replacement for the AISC-1210H-4R7N-T?

A: Yes. Both components share identical inductance values, current ratings, package formats, and core materials. The TDK substitute meets or exceeds all electrical and mechanical specifications of the original part.

Q: What are the differences between these two inductors?

A: The primary differences are inductance tolerance (±20% vs ±30%), DC resistance (240mOhm vs 247mOhm maximum), operating temperature range (-40°C ~ 105°C vs -25°C ~ 85°C), and product status (active vs obsolete). The TDK component offers tighter tolerance and extended temperature performance.

Q: Are there any package or footprint considerations?

A: Both components use the 1210 (3225 Metric) surface mount package. Physical dimensions are similar with minor variations: the TDK part measures 0.126" L x 0.098" W (3.20mm x 2.50mm) versus the Abracon part at 0.138" L x 0.098" W (4.60mm x 2.50mm). These differences are within standard PCB design tolerances for this package class.

Q: Is the TDK substitute compliant with environmental regulations?

A: Yes. The NLCV32T-4R7M-EFR is ROHS3 compliant and REACH unaffected, matching the compliance profile of the original component.

Q: What is the moisture sensitivity level for these inductors?

A: Both components have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
