Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: inductance value (2.2 µH), package footprint (1008 / 2520 Metric), mounting type (surface mount), core material (ferrite), and shielding configuration (unshielded). Current rating and DC resistance are secondary considerations; substitutes with lower current ratings or higher DCR values represent design trade-offs requiring circuit validation.

The NLCV25T-2R2M-PFR has two qualified substitutes:

NLCV25T-2R2M-EFR (TDK Corporation): Identical electrical specifications with active product status, differing only in series designation and operating temperature maximum (105°C vs. 125°C).

CW252016-2R2G and CW252016-2R2J (Bourns Inc.): Same inductance, package, and core configuration. These parts feature significantly lower current ratings (250 mA vs. 730 mA) and higher DCR values (2.8Ohm vs. 324mOhm), representing a different performance class suitable only for lower-power applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: NLCV25T-2R2M-EFR is the direct equivalent for the NLCV25T-2R2M-PFR. Both parts maintain identical electrical performance across inductance, current rating, and DC resistance. The only design consideration is the reduced operating temperature maximum of 105°C versus 125°C; applications requiring the full 125°C upper limit must remain on the original part or evaluate alternative suppliers. NLCV25T-2R2M-EFR carries active product status and full ROHS3 compliance.

Alternative Substitutes: CW252016-2R2G and CW252016-2R2J are electrically distinct from the primary part due to significantly reduced current handling (250 mA vs. 730 mA) and substantially higher DC resistance (2.8Ohm vs. 324mOhm). These Bourns components are suitable only for applications with lower current requirements and can tolerate increased resistive losses. Both variants are active products with ROHS3 compliance. CW252016-2R2J is supplied in Tape & Reel packaging; CW252016-2R2G packaging is unspecified.

Frequently Asked Questions (FAQ)

Q: Can NLCV25T-2R2M-EFR directly replace NLCV25T-2R2M-PFR in all applications?

A: NLCV25T-2R2M-EFR is electrically equivalent with one exception: the maximum operating temperature is 105°C instead of 125°C. If your circuit operates within -40°C to 105°C, direct substitution is valid. Applications requiring 125°C operation must use the original part or select an alternative supplier.

Q: Why do the Bourns CW252016 parts have such different current and resistance specifications?

A: CW252016-2R2G and CW252016-2R2J represent a different inductor design class optimized for lower-power applications. While they share the same inductance value and package footprint, their internal construction results in 250 mA current rating and 2.8Ohm DCR. These parts are not suitable for circuits designed around the 730 mA / 324mOhm performance envelope of the original part.

Q: What is the difference between CW252016-2R2G and CW252016-2R2J?

A: Both parts are electrically identical with the same inductance, current rating, and DC resistance. The primary difference is packaging: CW252016-2R2J is supplied in Tape & Reel format suitable for automated assembly, while CW252016-2R2G packaging is not specified. Tolerance also differs slightly (±2% vs. ±5%), with CW252016-2R2G offering tighter tolerance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. NLCV25T-2R2M-PFR, NLCV25T-2R2M-EFR, CW252016-2R2G, and CW252016-2R2J are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the footprint compatibility between these parts?

A: All four parts use the 1008 (2520 Metric) package with identical length (0.098" / 2.50mm) and width (0.079" / 2.00mm). Height differences are minimal: NLCV25T series at 0.075" (1.90mm) maximum and CW252016 series at 0.071" (1.80mm) maximum. All are surface mount compatible with standard PCB layouts.
