Substitute Part Grouping Explanation

Substitution eligibility for the NLCV25T-4R7M-PFD is determined by strict equivalence across the following critical parameters:

• Inductance value: 4.7 µH
• Inductance tolerance: ±20%
• Current rating: 285 mA minimum
• DC resistance: 1.04 Ohm maximum
• Core material and shielding: Ferrite, unshielded
• Package / case: 1008 (2520 Metric)
• Mounting type: Surface mount
• Operating temperature range: -40°C ~ 105°C minimum
• Regulatory compliance: AEC-Q200 certification

The NLCV25T-4R7M-EFD meets all substitution criteria. Both parts share identical electrical specifications, thermal ratings, and mechanical dimensions. The primary difference is the series designation (PFD versus EFD) and product status, with the EFD variant maintained as an active product by TDK Corporation.

Parameter Comparison

Engineering Selection Recommendations

The NLCV25T-4R7M-EFD is the direct equivalent substitute for the NLCV25T-4R7M-PFD. Both components are manufactured by TDK Corporation and maintain identical electrical, thermal, and mechanical specifications. The EFD variant carries an "Active" product status, ensuring continued availability and supply chain support.

For applications currently using the NLCV25T-4R7M-PFD, transition to the NLCV25T-4R7M-EFD provides full functional compatibility without design modification. Both parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 compliance mandates. The series designation change (PFD to EFD) reflects TDK's product line consolidation and does not affect electrical performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the NLCV25T-4R7M-EFD be used as a direct replacement for the NLCV25T-4R7M-PFD?

A: Yes. Both parts are electrically and mechanically identical. The NLCV25T-4R7M-EFD provides full substitution compatibility with no circuit modifications required.

Q: What is the difference between the PFD and EFD series designations?

A: The series designation reflects TDK's internal product line organization. The PFD variant has been discontinued for new designs, while the EFD variant remains in active production. Electrical and mechanical specifications are identical.
