Substitute Part Grouping Explanation

Substitute parts for the NLCV32T-2R2M-PF are evaluated based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Inductance value: 2.2 µH
Current rating: 770 mA minimum
DC resistance: 169mOhm maximum
Package / Case: 1210 (3225 Metric)
Core material: Ferrite

Tolerance specification
Shielding configuration

The NLCV32T-2R2M-EF is a direct equivalent from TDK Corporation within the active NLCV-EF series, maintaining identical electrical and mechanical specifications while offering current production availability.

The B82422H1223K000 from EPCOS - TDK Electronics does not meet the primary matching criteria due to different inductance value (22 µH vs. 2.2 µH), current rating (330 mA vs. 770 mA), and DC resistance (1Ohm vs. 169mOhm). This part is listed in the original substitute field but does not qualify as a functional equivalent.

Engineering Selection Recommendations

NLCV32T-2R2M-EF is the qualified substitute for NLCV32T-2R2M-PF. Both parts are manufactured by TDK Corporation and maintain identical electrical specifications (2.2 µH, 770 mA, 169mOhm DCR) and mechanical dimensions (1210 package). The NLCV32T-2R2M-EF carries Active product status, ensuring ongoing availability and manufacturing support. Both parts meet ROHS3 compliance and MSL 1 requirements. The primary distinction is series designation (NLCV-EF versus NLCV-PF), with the EF variant representing the current production line.

B82422H1223K000 does not qualify as a substitute due to fundamental electrical parameter mismatches. The inductance value (22 µH) is ten times higher than the required specification, current rating (330 mA) is insufficient for 770 mA applications, and DC resistance (1Ohm) exceeds the 169mOhm maximum. While this part shares ferrite core construction and similar physical dimensions, the electrical characteristics make it unsuitable for direct replacement in circuits designed for the NLCV32T-2R2M-PF.

Frequently Asked Questions (FAQ)

Q: Can NLCV32T-2R2M-EF be used as a direct replacement for NLCV32T-2R2M-PF?

A: Yes. Both parts have identical inductance (2.2 µH), current rating (770 mA), DC resistance (169mOhm maximum), package dimensions (1210 / 3225 Metric), and operating temperature range (-40°C to 105°C). The NLCV32T-2R2M-EF is the active production equivalent.

Q: Why is B82422H1223K000 listed as a substitute if it does not match specifications?

A: B82422H1223K000 appears in the original substitute field but does not meet the electrical requirements for functional equivalence. The 22 µH inductance, 330 mA current rating, and 1Ohm DCR are fundamentally different from the 2.2 µH, 770 mA, 169mOhm specifications required. This part should not be used as a replacement.

Q: What are the critical parameters for substitution compatibility?

A: Inductance value (2.2 µH), current rating (770 mA minimum), DC resistance (169mOhm maximum), and package type (1210 surface mount) are the primary criteria. Secondary factors include operating temperature range, RoHS compliance, and core material (ferrite, unshielded).

Q: Are there packaging differences between the main part and substitute?

A: NLCV32T-2R2M-PF is supplied in Tape & Reel (TR) packaging, while NLCV32T-2R2M-EF is also supplied in Tape & Reel (TR) packaging. Both use identical 1210 (3225 Metric) surface mount package format with matching physical dimensions and height specifications.

Q: What is the difference between NLCV-PF and NLCV-EF series designations?

A: The NLCV-PF series carries "Not For New Designs" status, indicating end-of-life or transition phase. The NLCV-EF series is the active production line from TDK Corporation with current manufacturing support and inventory availability.
