Substitute Part Grouping Explanation

Substitution for the NLCV25T-3R3M-PF is determined by the following critical parameters:

Inductance Value: 3.3 µH (exact match required)
Package / Case: 1008 (2520 Metric) (exact match required)
Mounting Type: Surface Mount (exact match required)
Core Material: Ferrite, Unshielded (exact match required)

Engineering Selection Recommendations

NLCV25T-3R3M-EF is the primary recommended substitute. This TDK Corporation part maintains identical electrical specifications (3.3 µH, 340 mA, 845mOhm DCR) and mechanical compatibility with the main part. The NLCV25T-3R3M-EF carries Active product status, ensuring continued availability and support for new designs. Both parts are ROHS3 compliant with MSL 1 rating.

CW252016-3R3J from Bourns Inc. is a secondary substitute option. While it matches the 3.3 µH inductance, package dimensions, and self-resonant frequency, it presents electrical trade-offs: current rating is reduced to 185 mA (versus 340 mA) and DC resistance increases to 3.4Ohm Max (versus 845mOhm). The CW252016-3R3J offers improved inductance tolerance (±5% versus ±20%) and extended operating temperature range (-40°C ~ 125°C). This part is suitable only for applications where the lower current rating and higher DC resistance are acceptable.

Frequently Asked Questions (FAQ)

Q: Can NLCV25T-3R3M-EF directly replace NLCV25T-3R3M-PF?

A: Yes. Both parts share identical inductance (3.3 µH), current rating (340 mA), DC resistance (845mOhm Max), package (1008 / 2520 Metric), and operating temperature range (-40°C ~ 105°C). The primary difference is product status: NLCV25T-3R3M-EF is Active, while NLCV25T-3R3M-PF is Not For New Designs.

Q: What are the limitations of CW252016-3R3J as a substitute?

A: The CW252016-3R3J has a maximum current rating of 185 mA, which is 45% lower than the 340 mA rating of the main part. Additionally, its DC resistance is 3.4Ohm Max, significantly higher than the 845mOhm specification. These differences make it unsuitable for applications requiring the full 340 mA current capacity or low-loss characteristics of the original part.

Q: Are packaging formats interchangeable between these parts?

A: The three parts use identical package dimensions (1008 / 2520 Metric, 0.098" L x 0.079" W, 2.50mm x 2.00mm). However, packaging format differs: NLCV25T-3R3M-PF and CW252016-3R3J are supplied in Tape & Reel (TR), while NLCV25T-3R3M-EF is supplied in Cut Tape (CT) & Digi-Reel®. Verify your assembly equipment compatibility with the selected packaging format.

Q: Do all substitute parts meet RoHS and REACH requirements?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All are classified under ECCN EAR99 and HTSUS 8504.50.8000.

Q: What is the inductance tolerance difference between substitutes?

A: NLCV25T-3R3M-PF and NLCV25T-3R3M-EF both have ±20% tolerance. CW252016-3R3J offers tighter tolerance at ±5%, which may be beneficial for precision applications but does not affect basic substitution compatibility.
