Key Parameters

Substitute Part Grouping Explanation

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

Primary Matching Criteria:

• Inductance value: 2.2 µH (within tolerance band)
• Current rating: minimum 1.2 A
• DC resistance: maximum 138 mOhm
• Core material: Ferrite
• Shielding configuration: Unshielded
• Package / Case: 1210 (3225 Metric)
• Mounting type: Surface Mount

Secondary Compatibility Factors:

• Operating temperature range (must encompass or exceed -40°C ~ 125°C)
• RoHS3 compliance
• Moisture sensitivity level (MSL 1 or equivalent)

The NLCV32T-2R2M-PFR is listed with two substitute part numbers. The first substitute, NLCV32T-2R2M-EFR, is a direct equivalent from the same manufacturer series with identical electrical specifications but active product status. The second substitute, B82422H1223K000, does not meet the primary matching criteria and is not a functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

NLCV32T-2R2M-EFR is the qualified substitute for NLCV32T-2R2M-PFR. Both components share identical electrical specifications (2.2 µH inductance, 1.2 A current rating, 138 mOhm DCR) and mechanical compatibility (1210 package, surface mount). The primary distinction is product status: NLCV32T-2R2M-EFR carries Active status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and MSL 1 rating. The operating temperature range of NLCV32T-2R2M-EFR (-40°C ~ 105°C) is narrower than the original part by 20°C at the upper limit; this difference must be evaluated against specific application thermal requirements.

B82422H1223K000 is not a functional substitute. The inductance value (22 µH) is 10 times higher than the required 2.2 µH, the current rating (330 mA) is insufficient for the 1.2 A requirement, and the package configuration (2-SMD, J-Lead) differs from the 1210 standard package. These deviations preclude direct substitution.

Frequently Asked Questions (FAQ)

Q: Can NLCV32T-2R2M-EFR be used as a direct replacement for NLCV32T-2R2M-PFR?

A: Yes. Both parts have identical inductance (2.2 µH), current rating (1.2 A), DC resistance (138 mOhm Max), core material (ferrite), shielding (unshielded), and package (1210). The primary difference is product status and a 20°C reduction in maximum operating temperature. Verify that your application does not require operation above 105°C.

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

A: B82422H1223K000 is not a functional equivalent. It has a different inductance value (22 µH vs. 2.2 µH), lower current rating (330 mA vs. 1.2 A), higher DC resistance (1 Ohm vs. 138 mOhm), and different package configuration (2-SMD, J-Lead vs. 1210). This part cannot replace NLCV32T-2R2M-PFR in applications requiring the specified electrical characteristics.

Q: What are the critical parameters for substitution compatibility?

A: Inductance value, current rating, DC resistance, core material, shielding type, and package configuration are the primary determinants. Secondary factors include operating temperature range, RoHS compliance, and moisture sensitivity level. All must align with application requirements.

Q: Does the narrower operating temperature range of NLCV32T-2R2M-EFR affect compatibility?

A: The upper temperature limit is reduced from 125°C to 105°C. If your application operates within -40°C to 105°C, there is no impact. Applications requiring sustained operation above 105°C require thermal analysis to confirm the substitute is suitable.

Q: Are both parts available in the same packaging format?

A: NLCV32T-2R2M-PFR is supplied in Tape & Reel (TR) packaging. NLCV32T-2R2M-EFR is also supplied in Tape & Reel (TR) packaging. Both are compatible with standard surface mount assembly processes.
