Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NRS5020T4R7MMGJV is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 4.7 µH (exact match required)
• Current rating: minimum 2 A
• Core material: Ferrite
• Operating temperature range: -40°C to 125°C minimum
• AEC-Q200 compliance
• RoHS3 compliance
• Surface mount configuration

Secondary Compatibility Factors:

• DC resistance within acceptable operating limits
• Frequency characteristics at 100 kHz test frequency
• Physical footprint compatibility (4.90mm x 4.90mm base dimension)
• Shielding configuration (shielded preferred for EMI-sensitive applications)

The identified substitute parts meet the primary matching criteria with documented variations in DC resistance, current saturation ratings, and shielding characteristics. These variations are within acceptable engineering tolerances for equivalent component selection.

Parameter Comparison

Engineering Selection Recommendations

LCXND5050WKT4R7MMG (Taiyo Yuden - Direct Substitute)

This part represents the primary equivalent option. It maintains identical inductance, current rating, and saturation characteristics while reducing DC resistance from 72 mOhm to 60 mOhm. The component is manufactured by the same supplier as the original part, ensuring consistent design philosophy and quality standards. Product status is active, supporting long-term availability. The primary distinction is the unshielded configuration, which may require evaluation in applications with strict electromagnetic interference requirements. Both parts share identical physical footprint dimensions and thermal operating range. AEC-Q200 and RoHS3 compliance are maintained.

AWVS005050204R7T00 (Pulse Electronics - Similar Substitute)

This part provides an alternative from a different manufacturer with enhanced current rating capability (2.6 A versus 2 A). DC resistance is equivalent to the LCXND5050WKT4R7MMG at 60 mOhm. The component maintains shielded configuration, matching the original part's EMI characteristics. Physical footprint is slightly larger (5.00mm x 5.00mm versus 4.90mm x 4.90mm), requiring verification of PCB layout compatibility. Inductance tolerance is wider at ±30% compared to ±20% for the original part. Current saturation rating is 1.9 A, which is marginally below the 2 A specification of the original part. AEC-Q200 and RoHS3 compliance are maintained. Product status is active.

Selection Criteria:

For applications requiring identical shielding characteristics and maintaining the original manufacturer's design lineage, LCXND5050WKT4R7MMG is the recommended selection. For applications where increased current headroom and shielded configuration are priorities, and where the slightly larger footprint can be accommodated, AWVS005050204R7T00 is suitable. Applications sensitive to DC resistance performance will benefit from either substitute, as both reduce resistance to 60 mOhm from the original 72 mOhm maximum.

Frequently Asked Questions (FAQ)

Q: Can LCXND5050WKT4R7MMG be used as a direct replacement for NRS5020T4R7MMGJV?

A: LCXND5050WKT4R7MMG meets all primary electrical specifications including inductance, current rating, saturation current, and operating temperature range. The primary difference is the unshielded configuration versus the shielded original. In applications where electromagnetic shielding is not critical, this part provides direct functional equivalence with improved DC resistance performance. Physical footprint dimensions are identical.

Q: What is the impact of the unshielded design in LCXND5050WKT4R7MMG?

A: Unshielded inductors exhibit higher electromagnetic field radiation compared to shielded designs. Applications requiring isolation from or immunity to external magnetic fields, or applications where the inductor must not interfere with adjacent sensitive circuitry, should retain the shielded configuration. The AWVS005050204R7T00 maintains shielding if this characteristic is mandatory.

Q: Why does AWVS005050204R7T00 have a different physical footprint?

A: AWVS005050204R7T00 uses a 2020 (5050 metric) package designation with dimensions of 5.00mm x 5.00mm x 2.20mm, compared to the 4.90mm x 4.90mm x 2.00mm footprint of the original part. This represents a different package family from Pulse Electronics. PCB layout compatibility must be verified before selection, as the larger footprint may not fit existing component placement patterns.

Q: Are all three parts AEC-Q200 qualified?

A: Yes. NRS5020T4R7MMGJV, LCXND5050WKT4R7MMG, and AWVS005050204R7T00 all carry AEC-Q200 automotive qualification ratings, ensuring compliance with automotive reliability and quality standards.

Q: What is the significance of the product status difference?

A: NRS5020T4R7MMGJV is marked as "Not For New Designs," indicating Taiyo Yuden has discontinued active development and recommends against its use in new applications. Both LCXND5050WKT4R7MMG and AWVS005050204R7T00 are marked as "Active," indicating ongoing manufacturer support, continued availability, and suitability for new designs. For legacy system support, any of the three parts are acceptable; for new designs, the active-status alternatives are preferred.

Q: How do the DC resistance values affect circuit performance?

A: The original NRS5020T4R7MMGJV specifies 72 mOhm maximum DC resistance. Both substitutes reduce this to 60 mOhm, resulting in lower resistive losses and reduced heat generation at rated current. In power delivery applications, this improvement enhances efficiency. Applications with tight thermal budgets or high-frequency switching benefit from the lower resistance values.

Q: Can AWVS005050204R7T00 be used in circuits designed for 2 A maximum current?

A: AWVS005050204R7T00 has a saturation current rating of 1.9 A, which is marginally below the 2 A specification of the original part. In applications operating continuously at or near 2 A, this part may saturate before reaching the design current limit. Applications with peak currents below 1.9 A or with average currents significantly below 2 A are suitable for this substitute. The higher continuous current rating of 2.6 A applies only below saturation.

Q: Are all parts RoHS3 compliant?

A: Yes. NRS5020T4R7MMGJV, LCXND5050WKT4R7MMG, and AWVS005050204R7T00 are all RoHS3 compliant, meeting restrictions on hazardous substances in electrical and electronic equipment.
