Engineering Selection Recommendations

NLCV32T-4R7M-EF is the primary substitute for NLCV32T-4R7M-PF. Both components are manufactured by TDK Corporation within the same product family (NLCV series). The NLCV32T-4R7M-EF maintains identical electrical specifications and physical dimensions while offering Active product status, ensuring long-term availability and supply chain continuity. The packaging difference (Tape & Reel versus Cut Tape) does not affect electrical or mechanical compatibility.

B82422H1472K000 is an alternative substitute manufactured by EPCOS - TDK Electronics (TDK subsidiary). This component provides enhanced specifications including tighter inductance tolerance (±10% versus ±20%), higher current rating (700 mA versus 620 mA), and extended operating temperature range (-55°C ~ 150°C versus -40°C ~ 105°C). The B82422H1472K000 carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. Physical dimensions and footprint compatibility are maintained. The package designation differs (2-SMD, J-Lead versus standard 1210), but the supplier device package remains 1210 (3225 Metric) equivalent.

Both substitutes maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can NLCV32T-4R7M-EF be used as a direct replacement for NLCV32T-4R7M-PF?

A: Yes. Both components share identical inductance (4.7 µH), current rating (620 mA), DC resistance (260mOhm Max), and physical dimensions (1210 / 3225 Metric). The primary difference is packaging format (Tape & Reel versus Cut Tape) and product status (Active versus Not For New Designs). Electrical and mechanical compatibility is complete.

Q: What are the advantages of B82422H1472K000 over NLCV32T-4R7M-EF?

A: The B82422H1472K000 offers three technical advantages: tighter inductance tolerance (±10% versus ±20%), higher current rating (700 mA versus 620 mA), and extended operating temperature range (-55°C ~ 150°C versus -40°C ~ 105°C). Additionally, it carries AEC-Q200 automotive qualification. These enhancements make it suitable for demanding applications, though it is not required for standard replacements.

Q: Are there package compatibility concerns when substituting B82422H1472K000?

A: The B82422H1472K000 uses a 2-SMD, J-Lead package designation, while the original uses standard 1210 (3225 Metric). However, the supplier device package and physical dimensions (0.126" L x 0.098" W, 0.094" Max height) are equivalent, ensuring PCB footprint compatibility without layout modifications.

Q: Do all three parts meet compliance requirements?

A: Yes. NLCV32T-4R7M-PF, NLCV32T-4R7M-EF, and B82422H1472K000 are all RoHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic components.

Q: Why is NLCV32T-4R7M-PF marked "Not For New Designs"?

A: This status indicates that TDK has discontinued this specific variant for new product development. Existing designs using this component should transition to NLCV32T-4R7M-EF (same series, active status) or B82422H1472K000 (enhanced specifications) to ensure long-term supply availability and manufacturing support.
