Is there a pin-compatible replacement for NLV32T-R56J-EF?

FHW1210HCR56JGT is a form-fit compatible candidate in a 1210 package. However, its much higher DCR means it is not a direct pin-for-pin functional equivalent without engineering review.

What risks should I check before replacing NLV32T-R56J-EF?

Key risks include: 1) Package mismatch requiring a new PCB layout. 2) Higher DC Resistance (DCR) causing more power loss. 3) A lower Self-Resonant Frequency (SRF). 4) A reduced operating temperature range.

NLV32T-R56J-EF Alternatives, Datasheet & Cross Reference | TDK Electronics AG

Finding a substitute for the TDK NLV32T-R56J-EF, a 560nH, 450mA inductor in a 1210 package, requires careful review. While some alternatives match the package, key specs like DCR or temperature may differ.

AI replacement insight

Electrical riskhigh

DCR, SRF, and temperature range vary significantly across candidates.

Package riskmedium

Some candidates require a different PCB footprint, which is a high-impact change.

Sourcing risklow

Multiple vendors offer similar parts, providing sourcing flexibility.

Can it be replaced directly?

No direct, drop-in replacement has been verified. FHW1210HCR56JGT shares the same package and inductance but has a significantly higher DCR (1.1Ω vs 0.55Ω), which impacts efficiency.

Best replacement path

The best path is to find a 1210 package inductor with 560nH inductance, current rating ≥450mA, and DCR ≤0.55Ω. FHW1210HCR56JGT is a form-fit match but has higher DCR, requiring review.

Main risk

The main risk is increased power loss from higher DC Resistance (DCR) in form-fit alternatives, or needing a PCB redesign for functional alternatives in different packages.

Recommended alternatives

Same 1210 package and 560nH inductance, with higher current rating but significantly worse DCR.
