NLCV32T-4R7M-PFD Equivalent & Substitute Parts

Part Overview

The NLCV32T-4R7M-PFD is a 4.7 µH unshielded drum core wirewound inductor manufactured by TDK Corporation, rated for 620 mA continuous current with a maximum DC resistance of 260mOhm. This surface mount component is packaged in 1210 (3225 Metric) format and is compliant with AEC-Q200 automotive standards.

The NLCV32T-4R7M-PFD carries a "Not For New Designs" product status, indicating that TDK has discontinued this variant for new applications. Identifying equivalent substitute parts is necessary to ensure design continuity and maintain supply chain reliability for existing production or legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NLCV32T-4R7M-PFD must satisfy the following electrical and mechanical criteria:

Primary Matching Criteria:

• Inductance value: 4.7 µH
• Core material: Ferrite
• Shielding configuration: Unshielded
• Package / Case: 1210 (3225 Metric) or compatible footprint
• Mounting type: Surface Mount
• AEC-Q200 compliance

Secondary Compatibility Criteria:

• Current rating must equal or exceed 620 mA
• DC resistance must not exceed 260mOhm
• Operating temperature range must encompass -40°C ~ 105°C minimum
• RoHS3 compliance required

Two substitute parts meet these criteria with variations in packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

NLCV32T-4R7M-EFD is the primary recommended substitute. This part is manufactured by TDK Corporation under the active NLCV-EFD series and maintains identical electrical specifications to the main part. The only difference is packaging format: Cut Tape (CT) versus Tape & Reel (TR). Both formats are suitable for surface mount assembly. This substitute provides direct functional equivalence with active product status, ensuring long-term supply availability.

B82422H1472K000 is an alternative substitute manufactured by EPCOS - TDK Electronics. This part offers improved specifications in three areas: tighter inductance tolerance (±10% versus ±20%), higher current rating (700 mA versus 620 mA), and lower maximum DC resistance (250mOhm versus 260mOhm). However, the package case designation differs (2-SMD, J-Lead versus 1210 standard), which may require PCB footprint verification before implementation. The extended operating temperature range (-55°C ~ 150°C) provides additional thermal margin beyond the original specification.

Both substitutes carry AEC-Q200 compliance and ROHS3 certification, meeting automotive and environmental standards equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can NLCV32T-4R7M-EFD be used as a direct replacement for NLCV32T-4R7M-PFD?

A: Yes. Both parts share identical electrical specifications: 4.7 µH inductance, 620 mA current rating, 260mOhm maximum DC resistance, and 1210 (3225 Metric) package dimensions. The difference in packaging format (Cut Tape versus Tape & Reel) does not affect electrical performance or PCB assembly compatibility.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on continuous reels suitable for high-volume automated assembly. Cut Tape packaging provides components in smaller quantities on tape strips, typically for lower-volume or prototype applications. Both formats contain identical components with the same electrical and mechanical properties.

Q: Is B82422H1472K000 compatible with the original NLCV32T-4R7M-PFD footprint?

A: The B82422H1472K000 uses a 2-SMD, J-Lead package case designation, while the original part uses standard 1210 (3225 Metric) format. Although both have identical physical dimensions (0.126" L x 0.098" W, 3.20mm x 2.50mm), the J-Lead configuration may differ in lead geometry. PCB footprint verification is required before substitution.

Q: Why does B82422H1472K000 have a ±10% inductance tolerance instead of ±20%?

A: Inductance tolerance is determined by the manufacturer's production process and quality control specifications. The tighter ±10% tolerance on B82422H1472K000 indicates higher manufacturing precision, which may provide improved circuit performance in applications sensitive to inductance variation.

Q: Are all three parts AEC-Q200 compliant?

A: Yes. NLCV32T-4R7M-PFD, NLCV32T-4R7M-EFD, and B82422H1472K000 all carry AEC-Q200 automotive qualification, confirming suitability for automotive and high-reliability applications.

Q: What is the significance of "Not For New Designs" status on the main part?

A: This designation indicates that TDK Corporation has discontinued the NLCV32T-4R7M-PFD for new product development. Existing inventory remains available, but new designs should transition to active alternatives such as NLCV32T-4R7M-EFD to ensure long-term supply continuity and manufacturer support.
