Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NLCV32T-1R0M-PF are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Inductance Value: Must be 1 µH (exact match)
• Current Rating: Must meet or exceed 1 A
• Package / Case: Must be 1210 (3225 Metric) or compatible footprint
• Mounting Type: Must be Surface Mount
• Core Material: Ferrite drum core construction
• Shielding: Unshielded configuration
• DC Resistance: Should not significantly exceed 78 mOhm Max to maintain circuit performance

Two substitute parts meet these criteria: the NLCV32T-1R0M-EF (TDK Corporation, Active status) and the B82422H1102K000 (EPCOS - TDK Electronics, Active status). Both maintain the same inductance, package footprint, and core material specifications. Variations in current rating, DC resistance, and operating temperature range reflect different product series and design generations.

Parameter Comparison

Engineering Selection Recommendations

NLCV32T-1R0M-EF is the primary substitute for the NLCV32T-1R0M-PF. Both parts are manufactured by TDK Corporation and share identical electrical specifications (1 µH inductance, 1 A current rating, 78 mOhm DCR, ±20% tolerance). The NLCV32T-1R0M-EF carries an Active product status, ensuring continued availability and manufacturing support. This part is the direct functional equivalent and requires no circuit redesign for implementation.

B82422H1102K000 is a secondary substitute manufactured by EPCOS - TDK Electronics. This part maintains the same 1 µH inductance and 1210 package footprint but offers enhanced specifications: higher current rating (1.15 A vs. 1 A), tighter tolerance (±10% vs. ±20%), and extended operating temperature range (-55°C to 150°C vs. -40°C to 105°C). The DC resistance is 100 mOhm Max, which is 22 mOhm higher than the main part. This part carries AEC-Q200 automotive qualification and Active product status. Selection of this substitute is appropriate when the enhanced current capacity, tighter tolerance, or extended temperature range provides circuit margin or meets specific application requirements.

Both substitute parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain the same unshielded ferrite drum core construction as the original part.

Frequently Asked Questions (FAQ)

Q: Can NLCV32T-1R0M-EF be used as a direct replacement for NLCV32T-1R0M-PF without circuit modification?

A: Yes. Both parts share identical inductance (1 µH), current rating (1 A), DC resistance (78 mOhm Max), tolerance (±20%), operating temperature range (-40°C to 105°C), and package footprint (1210 / 3225 Metric). No circuit redesign is required.

Q: What is the primary difference between NLCV32T-1R0M-EF and B82422H1102K000?

A: The NLCV32T-1R0M-EF is a direct equivalent with identical specifications. The B82422H1102K000 offers higher current rating (1.15 A), tighter inductance tolerance (±10%), extended temperature range (-55°C to 150°C), and AEC-Q200 qualification, but has higher DC resistance (100 mOhm Max). Selection depends on whether these enhanced specifications provide circuit benefit.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 1210 (3225 Metric) surface mount package with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.094" (2.40mm).

Q: Why is the NLCV32T-1R0M-PF marked "Not For New Designs"?

A: This status indicates that TDK Corporation has discontinued active development and marketing of this part series. The NLCV32T-1R0M-EF (Active status) is the recommended replacement for new design work.

Q: Does the higher DC resistance of B82422H1102K000 affect circuit performance?

A: The B82422H1102K000 has 100 mOhm Max DCR compared to 78 mOhm Max for the main part. The 22 mOhm difference may introduce additional resistive losses in high-current or precision applications. Verify that circuit performance remains acceptable within the application's tolerance specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three parts carry ROHS3 Compliant status and MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.
