Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NLCV32T-3R3M-PFD are identified based on the following critical parameters:

• Inductance Value: 3.3 µH (exact match required)
• Package / Case: 1210 (3225 Metric) surface mount format
• Core Material: Ferrite, unshielded drum core construction
• Current Rating: Minimum 690 mA
• DC Resistance: Maximum 208mOhm
• Compliance: AEC-Q200 automotive qualification
• RoHS Status: ROHS3 Compliant

Two substitute parts meet these criteria:

1. NLCV32T-3R3M-EFD (TDK Corporation, NLCV-EFD Series) – Direct series variant with identical electrical specifications and Active product status
2. B82422H1332K000 (EPCOS - TDK Electronics, SIMID Series) – Alternative manufacturer series with compatible electrical performance and enhanced current rating

Parameter Comparison

Engineering Selection Recommendations

NLCV32T-3R3M-EFD is the primary substitute for the NLCV32T-3R3M-PFD. Both parts are manufactured by TDK Corporation within the NLCV series family, share identical electrical specifications, and maintain the same 1210 (3225 Metric) package format. The NLCV32T-3R3M-EFD carries Active product status, ensuring long-term availability and supply chain support. This part is recommended for direct replacement in existing designs.

B82422H1332K000 is an alternative substitute manufactured by EPCOS - TDK Electronics under the SIMID series. This part meets all critical electrical requirements with enhanced performance characteristics: higher current rating (770 mA vs. 690 mA), lower DC resistance (180mOhm vs. 208mOhm), and extended operating temperature range (-55°C ~ 150°C vs. -40°C ~ 105°C). However, the package format differs (2-SMD, J-Lead vs. 1210 standard), requiring PCB layout verification before implementation. This part is suitable for applications where improved thermal performance or extended temperature operation is beneficial.

Both substitute parts maintain AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can NLCV32T-3R3M-EFD be used as a direct replacement for NLCV32T-3R3M-PFD?

A: Yes. Both parts share identical inductance (3.3 µH), current rating (690 mA), DC resistance (208mOhm Max), and package format (1210 / 3225 Metric). No circuit modifications or PCB layout changes are required. The NLCV32T-3R3M-EFD is the recommended substitute due to its Active product status.

Q: What are the key differences between NLCV32T-3R3M-EFD and B82422H1332K000?

A: The primary difference is package format. NLCV32T-3R3M-EFD uses the standard 1210 (3225 Metric) package, while B82422H1332K000 uses a 2-SMD, J-Lead package. Additionally, B82422H1332K000 offers improved electrical performance (lower DCR, higher current rating) and extended temperature range. PCB footprint compatibility must be verified before selecting B82422H1332K000.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. NLCV32T-3R3M-EFD and B82422H1332K000 both carry AEC-Q200 automotive qualification ratings, matching the original NLCV32T-3R3M-PFD specification.

Q: Does the tolerance difference between NLCV32T-3R3M-EFD (±20%) and B82422H1332K000 (±10%) affect circuit performance?

A: Tolerance differences may impact circuit performance in applications with tight inductance specifications. B82422H1332K000 offers tighter tolerance (±10%), which may be advantageous for precision filtering or impedance matching circuits. Circuit simulation or testing is recommended if tolerance sensitivity is a design concern.

Q: Can B82422H1332K000 be used in applications requiring the -40°C ~ 105°C operating range?

A: Yes. B82422H1332K000 supports an extended operating temperature range of -55°C ~ 150°C, which encompasses the original -40°C ~ 105°C specification. This part is fully compatible with the original temperature requirements.

Q: What is the impact of different self-resonant frequencies (54MHz vs. 70MHz)?

A: Self-resonant frequency affects high-frequency performance. NLCV32T-3R3M-EFD maintains the original 54MHz specification. B82422H1332K000 has a higher self-resonant frequency (70MHz), which may provide improved performance in high-frequency applications but requires circuit validation to confirm compatibility.
