Part Overview

The NRS6010T4R7MMGF is a 4.7 µH shielded drum core wirewound inductor manufactured by Taiyo Yuden, rated for 1.4 A continuous current with a maximum DC resistance of 198 mOhm. This surface mount component is housed in a 2304 (6010 Metric) package measuring 6.00mm × 6.00mm × 1.00mm. The part is designated as Not For New Designs, indicating it has been superseded in the manufacturer's product line. Identification of equivalent substitute parts is necessary for applications requiring continued sourcing, design updates, or inventory management where the original part is no longer actively produced.

Substitute Part Grouping Explanation

Substitution of the NRS6010T4R7MMGF is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Inductance value: 4.7 µH (exact match required)
• Inductance tolerance: ±20% or tighter
• Current rating: 1.4 A minimum
• Saturation current (Isat): 1.3 A minimum
• Shielding: Shielded construction
• Mounting type: Surface Mount
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Secondary Compatibility Factors:

• DC resistance: Lower or equivalent to 198 mOhm preferred
• Operating temperature range: Must encompass -25°C ~ 125°C or broader
• Package dimensions: Physical compatibility with 6.00mm × 6.00mm footprint and 1.00mm height tolerance
• Inductance test frequency: 100 kHz or 1 MHz acceptable

The substitute parts listed below meet the primary equivalence criteria. Variations in DC resistance, package designation, and inductance test frequency are noted where they differ from the main part specification.

Parameter Comparison

Engineering Selection Recommendations

BWVH005956104R7M00 and BWVH005956104R7T00 (Pulse Electronics)

Both Pulse Electronics variants are active products with ROHS3 compliance and unlimited MSL rating. These parts deliver lower DC resistance (165 mOhm versus 198 mOhm), reducing power dissipation in the application. The extended operating temperature range (-55°C ~ 125°C) provides broader environmental coverage. The primary trade-off is a reduced current rating of 1.3 A compared to the original 1.4 A specification. The BWVH005956104R7M00 maintains ±20% inductance tolerance matching the original part, while the BWVH005956104R7T00 specifies ±30% tolerance. Footprint dimensions are slightly smaller (5.90mm × 5.60mm), requiring PCB layout verification for compatibility.

LMLP0606N4R7CTAR (KYOCERA AVX)

This active product maintains the original 1.4 A current rating and identical 6.00mm × 6.00mm footprint dimensions. ROHS3 compliance and unlimited MSL rating are confirmed. The part exhibits higher DC resistance (290 mOhm versus 198 mOhm), resulting in increased power dissipation. The ±30% inductance tolerance is wider than the original ±20% specification. Operating temperature range (-40°C ~ 125°C) is narrower than the Pulse Electronics alternatives but covers the original specification. Height is marginally increased to 1.10mm, requiring clearance verification in compact designs.

All three substitute parts satisfy the core electrical and mechanical requirements for 4.7 µH shielded surface mount inductors with active product status and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the BWVH005956104R7M00 or BWVH005956104R7T00 be used as direct replacements for the NRS6010T4R7MMGF?

A: These Pulse Electronics parts meet the primary equivalence criteria for inductance, saturation current, shielding, and compliance. The reduced current rating (1.3 A versus 1.4 A) requires circuit analysis to confirm the application does not exceed this limit. The smaller footprint (5.90mm × 5.60mm versus 6.00mm × 6.00mm) necessitates PCB layout verification. DC resistance is lower, which reduces power dissipation.

Q: What is the impact of the higher DC resistance in the LMLP0606N4R7CTAR?

A: The LMLP0606N4R7CTAR specifies 290 mOhm DC resistance compared to 198 mOhm in the original part. This 46% increase in resistance results in proportionally higher power dissipation (P = I²R). For a 1.4 A application, this translates to approximately 0.27 W dissipation in the substitute versus 0.19 W in the original. Thermal management and circuit performance must be evaluated accordingly.

Q: Are there footprint compatibility concerns with the Pulse Electronics substitutes?

A: The BWVH005956104R7M00 and BWVH005956104R7T00 measure 5.90mm × 5.60mm, which is slightly smaller than the original 6.00mm × 6.00mm footprint. Both maintain the same 1.00mm height. PCB land pattern and component placement clearances must be verified to ensure mechanical fit and solder joint integrity.

Q: How do inductance tolerance differences affect circuit performance?

A: The original NRS6010T4R7MMGF specifies ±20% tolerance. The BWVH005956104R7M00 maintains ±20%, while the BWVH005956104R7T00 and LMLP0606N4R7CTAR specify ±30%. Wider tolerance ranges introduce greater inductance variation across production batches. Applications with tight inductance requirements or frequency-dependent performance must account for this variation in circuit design margins.

Q: What is the significance of the different inductance test frequencies?

A: The original part is tested at 100 kHz, while the Pulse Electronics substitutes are tested at 1 MHz. Inductance values can vary with frequency due to core material properties. The 100 kHz test frequency aligns with the LMLP0606N4R7CTAR, providing closer correlation to the original measurement methodology. Applications operating at frequencies significantly different from the test frequency should consider frequency-dependent inductance characteristics.

Q: Are all substitute parts RoHS3 compliant and MSL rated?

A: Yes. All three substitute parts are ROHS3 compliant and carry MSL rating 1 (Unlimited), matching the original part's environmental and regulatory certifications.

Q: Which substitute part is recommended for applications with strict current requirements?

A: The LMLP0606N4R7CTAR maintains the original 1.4 A current rating and saturation current specification. The Pulse Electronics variants are rated for 1.3 A, which may be insufficient for applications requiring the full 1.4 A capability of the original part.
