NLCV25T-220K-PFD Equivalent & Substitute Parts

Part Overview

The NLCV25T-220K-PFD is a 22 µH unshielded drum core wirewound inductor manufactured by TDK Corporation, rated for 160 mA continuous current with a maximum DC resistance of 3.64Ohm. This surface mount component is packaged in 1008 (2520 Metric) format and is designed for applications requiring fixed inductance in compact form factors.

The NLCV25T-220K-PFD carries a "Not For New Designs" product status, indicating that TDK has transitioned this part to end-of-life. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support existing inventory management for active production lines.

Substitute Part Grouping Explanation

Substitution eligibility for the NLCV25T-220K-PFD is determined by strict equivalence across the following critical parameters:

• Inductance value: 22 µH (±10% tolerance maintained)
• Current rating: 160 mA minimum
• DC resistance: 3.64Ohm maximum
• Core material and type: Ferrite, drum core, wirewound, unshielded
• Package format: 1008 (2520 Metric) surface mount
• Operating temperature range: -40°C ~ 105°C minimum
• Frequency characteristics: Q @ 2.52MHz and self-resonant frequency alignment
• Compliance standards: AEC-Q200, ROHS3, MSL 1

The NLCV25T-220K-EFD meets all substitution criteria as a manufacturer-recommended equivalent from TDK Corporation, with identical electrical specifications and mechanical dimensions while maintaining active product status.

Parameter Comparison

Engineering Selection Recommendations

The NLCV25T-220K-EFD is the direct equivalent substitute for the NLCV25T-220K-PFD. Both parts are manufactured by TDK Corporation and share identical electrical and mechanical specifications across all critical parameters.

The primary distinction is product lifecycle status: the NLCV25T-220K-PFD is designated "Not For New Designs," while the NLCV25T-220K-EFD maintains "Active" status. This transition reflects TDK's product portfolio management and does not indicate any technical deficiency in the original part.

Both parts maintain full compliance with AEC-Q200 automotive-grade reliability standards, ROHS3 environmental regulations, and MSL 1 moisture sensitivity classification. The electrical performance, thermal operating range, and mechanical form factor are identical, ensuring direct pin-compatible and functional substitution in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the NLCV25T-220K-EFD be used as a direct replacement for the NLCV25T-220K-PFD?

A: Yes. The NLCV25T-220K-EFD is electrically and mechanically identical to the NLCV25T-220K-PFD. All critical parameters including inductance, current rating, DC resistance, package dimensions, and operating temperature range are equivalent. The parts are pin-compatible and functionally interchangeable.

Q: Why is the NLCV25T-220K-PFD marked "Not For New Designs"?

A: This designation indicates that TDK has transitioned the part to end-of-life status and recommends using the NLCV25T-220K-EFD for new designs. This is a standard lifecycle management practice and does not reflect any performance or reliability issue with the original part.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical AEC-Q200 ratings, ROHS3 compliance, and MSL 1 moisture sensitivity classifications. They meet the same regulatory and quality standards.

Q: What is the difference between the PFD and EFD designations in the part numbers?

A: The PFD and EFD suffixes indicate different product series within TDK's inductor portfolio. The EFD series represents the current active product line, while the PFD series has been transitioned to end-of-life. The electrical and mechanical specifications remain identical.

Q: Can I use these parts interchangeably in existing production?

A: Yes. The NLCV25T-220K-EFD can be substituted for the NLCV25T-220K-PFD without circuit modifications, PCB layout changes, or design re-qualification, provided the original design specifications match the documented parameters.

Q: Are there any inventory or lead time considerations?

A: The NLCV25T-220K-EFD maintains active production status with current inventory availability. The NLCV25T-220K-PFD is available from existing stock but is not recommended for new procurement due to its end-of-life designation.
