HCTL
A vertical 2-pin header with matching pitch and voltage, but a higher current rating. Footprint verification is required.
WAFER-VH3.96-2PZZ is a 2-pin, 3.96mm pitch straight through-hole header. Several functional alternatives with similar form factors and higher current ratings are available, but require footprint verification before use.
PCB footprint dimensions must be verified from datasheet to ensure mechanical fit.
Candidates have higher current ratings, which is a safe upgrade.
No drop-in replacement is verified. ZX-VH3.96-2PLT is a strong candidate that matches form and has better electrical ratings, but requires footprint confirmation.
Use a vertical 2-pin 3.96mm header like ZX-VH3.96-2PLT, after verifying the PCB footprint from its datasheet.
Mechanical mismatch in PCB footprint. The mounting orientation (straight/vertical) is correct for the suggested alternatives.
