Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NLCV25T-2R2M-PF is determined by the following critical parameters:

• Inductance Value: 2.2 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)
• Current Rating: Minimum 390 mA (equal or greater)
• DC Resistance: Maximum 650mOhm (equal or lower preferred)
• Operating Temperature Range: Minimum -40°C ~ 105°C coverage
• RoHS Compliance: ROHS3 Compliant (required)

The NLCV25T-2R2M-EF from TDK Corporation is a direct series variant with identical electrical and mechanical specifications, differing only in packaging format (Tape & Reel vs. Cut Tape). The Bourns CW252016 series parts (CW252016-2R2G and CW252016-2R2J) meet the core electrical requirements but operate with reduced current ratings and different DC resistance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: NLCV25T-2R2M-EF

The NLCV25T-2R2M-EF is the recommended substitute for the NLCV25T-2R2M-PF. Both parts are manufactured by TDK Corporation within the NLCV series and share identical electrical specifications, core construction, and package dimensions. The NLCV25T-2R2M-EF maintains Active product status, ensuring long-term availability and supply chain continuity. The only difference is packaging format (Tape & Reel vs. Cut Tape), which does not affect electrical performance or mechanical compatibility. This part is suitable for direct replacement in all applications.

Secondary Substitutes: CW252016-2R2G and CW252016-2R2J

The Bourns CW252016 series inductors (both CW252016-2R2G and CW252016-2R2J variants) provide functional equivalence for applications where current requirements do not exceed 250 mA. These parts maintain the same 2.2 µH inductance value, identical package dimensions, and surface mount configuration. Both variants are Active products with ROHS3 compliance. However, the following differences must be evaluated:

• Current rating is reduced from 390 mA to 250 mA
• DC resistance is significantly higher (2.8Ohm vs. 650mOhm)
• Operating temperature range extends to 125°C (vs. 105°C)
• Inductance tolerance is tighter (±2% for CW252016-2R2G, ±5% for CW252016-2R2J vs. ±20%)

Selection between CW252016-2R2G and CW252016-2R2J depends on tolerance requirements and packaging preference (CW252016-2R2G is supplied in bulk; CW252016-2R2J is supplied on Tape & Reel).

Frequently Asked Questions (FAQ)

Q: Can NLCV25T-2R2M-EF be used as a direct replacement for NLCV25T-2R2M-PF?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape vs. Tape & Reel). No circuit modifications are required.

Q: What is the primary reason to substitute the NLCV25T-2R2M-PF?

A: The NLCV25T-2R2M-PF is classified as Not For New Designs. The NLCV25T-2R2M-EF provides an active alternative from the same manufacturer with identical specifications.

Q: Can Bourns CW252016 parts replace the TDK NLCV25T-2R2M-PF in all applications?

A: No. The Bourns CW252016 series is suitable only for applications where the maximum current requirement does not exceed 250 mA. If your circuit requires the full 390 mA rating, the Bourns alternative is not compatible.

Q: What is the impact of higher DC resistance in the Bourns CW252016 parts?

A: The CW252016 series has DC resistance of 2.8Ohm compared to 650mOhm in the NLCV25T-2R2M-PF. This significantly higher resistance will increase power dissipation and heat generation in the inductor. Circuit thermal analysis is required before substitution.

Q: Are all substitute parts RoHS3 compliant?

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

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

A: Both parts have identical electrical specifications. CW252016-2R2G is supplied in bulk packaging, while CW252016-2R2J is supplied on Tape & Reel. The inductance tolerance differs slightly (±2% vs. ±5%).

Q: Can the operating temperature range difference affect substitution?

A: The NLCV25T-2R2M-PF operates to 105°C, while Bourns CW252016 parts operate to 125°C. If your application operates within the -40°C to 105°C range, both are suitable. If higher temperatures are required, the Bourns parts provide additional margin.
