CW252016-82NJ Equivalent & Substitute Parts

Part Overview

The CW252016-82NJ is an 82 nH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 600 mA continuous current with a maximum DC resistance of 220 mOhm. This surface mount component in 1008 (2520 Metric) package is designed for high-frequency applications up to 1 GHz self-resonant frequency. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit operation within relaxed electrical parameters while maintaining mechanical compatibility and package equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CW252016-82NJ is determined by strict adherence to the following parameters:

Mandatory Matching Parameters:

• Inductance value: 82 nH
• Inductance tolerance: ±5%
• Package / Case: 1008 (2520 Metric)
• Mounting type: Surface Mount
• Shielding configuration: Unshielded

Allowable Parameter Variations: Substitute parts may differ in current rating, DC resistance, core material, Q factor, self-resonant frequency, and operating temperature range, provided the application design accommodates these variations without performance degradation.

The identified substitute NLV25T-082J-PF maintains identical inductance, tolerance, package, and mounting specifications while operating at reduced current capacity (300 mA versus 600 mA) and higher DC resistance (750 mOhm versus 220 mOhm).

Engineering Selection Recommendations

CW252016-82NJ (Primary Selection): Select the Bourns CW252016-82NJ for new designs and applications requiring the full 600 mA current rating, lower DC resistance profile, and extended operating temperature to 125°C. This part maintains active production status with unrestricted design-in eligibility.

NLV25T-082J-PF (Constrained Substitution): The TDK NLV25T-082J-PF is suitable only for existing designs or legacy applications where current requirements do not exceed 300 mA and the application can tolerate increased DC resistance (750 mOhm) and reduced operating temperature ceiling (105°C). This part carries "Not For New Designs" status and should not be selected for new product development. REACH compliance status differs between parts; verify regulatory requirements for your application region.

Both parts maintain identical mechanical compatibility, package footprint, and inductance specifications, enabling direct PCB layout substitution when electrical parameter constraints are satisfied.

Frequently Asked Questions (FAQ)

Q: Can NLV25T-082J-PF replace CW252016-82NJ in all applications?

A: No. Substitution is valid only when application current requirements do not exceed 300 mA. The NLV25T-082J-PF exhibits three times higher DC resistance (750 mOhm vs. 220 mOhm), resulting in increased power dissipation. Verify that your circuit design accommodates this resistance increase and the reduced operating temperature maximum of 105°C.

Q: Are the packages mechanically identical?

A: Yes. Both parts use the 1008 (2520 Metric) surface mount package with identical footprint dimensions (0.098" L × 0.079" W). PCB layout and reflow profiles remain unchanged between parts.

Q: What is the impact of different core materials?

A: The CW252016-82NJ uses ceramic core material while NLV25T-082J-PF uses ferrite core. This material difference contributes to the performance variations observed in Q factor, self-resonant frequency, and DC resistance. Core material selection affects frequency response characteristics and thermal stability.

Q: Why does NLV25T-082J-PF have "Not For New Designs" status?

A: This designation indicates the part is in mature or declining production phase. While suitable for sustaining existing products, it should not be selected for new product development due to uncertain long-term availability and potential future discontinuation.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. However, NLV25T-082J-PF carries "REACH Affected" status while CW252016-82NJ is "REACH Unaffected." Verify REACH compliance requirements for your target markets before final part selection.
