What this relay does on the board
The Panasonic AQH0223AZ is a solid-state signal relay from the AQ-H series, switching AC loads up to 300 mA across a 0 V to 600 V range. The SPST-NO (1 Form A) contact means it closes when the input side sees 1.21 VDC — a logic-level signal from a microcontroller or PLC output drives it directly without a separate driver transistor.
Active production — no last-time-buy worry
Panasonic lists the AQH0223AZ as Active. That means the factory is still building it, no end-of-life notice is on the table, and the supply channel is the normal authorized-distribution route. For a procurement desk, this part does not carry the obsolescence risk that drives spot-market premiums.
Package and handling for the rework bench
The 8-SMD body with 7 leads and gull-wing terminations is a hand-solderable package — no hot-air station required. The 0.300" width and 7.62 mm pitch give enough clearance for a fine-tip iron.
