No official successor order code is listed in the manufacturer's lifecycle records. A functional replacement would require a pin-compatible PhotoMOS relay from the same AQY family with matching 4-SON footprint, SPST-NO configuration, and similar load ratings. Available for sourcing through independent distribution and surplus channels; quantities, pricing, and lot traceability are confirmed at RFQ. Housed in a 4-SON (small-outline no-lead) package measuring 2.95 mm on the side — a low-profile, leadless SMD footprint suited for dense PCB layouts where height is constrained. Termination style is SMD (SMT) Tab, meaning the drain/source pads are flush with the package bottom; no through-hole or gull-wing leads. The PCB land pattern must match the 4-SON outline with appropriate solder-paste stencil aperture for reliable reflow.","metaTitle":"Panasonic AQY221N3M PhotoMOS Relay, SPST-NO, 150 mA","metaDescription":"Panasonic AQY221N3M PhotoMOS relay, SPST-NO, 150 mA load, 25 V, 7.5 Ohm on-resistance, 4-SON SMD.
