HFD42-3-3SR Signal Subminiature Mini Sealed Surface Mount Relay 3VDC DPDT

The HFD42-3-3SR is a high-performance subminiature sealed surface-mount (SMD) signal relay engineered for compact PCB applications requiring reliable low-voltage switching. Featuring a Form 2C (DPDT / 2c/o) contact arrangement, this relay enables precise dual-circuit switching while minimizing board space usage.

Designed with a 3VDC coil and 64.3 coil resistance, the relay delivers efficient operation and dependable actuation in low-voltage electronic systems. Its AgNi/Au (gold flash) contacts provide excellent conductivity, low contact resistance, and improved switching reliability for signal-level applications.

The relay supports switching loads up to 1A at 30VDC and 0.5A at 125VAC (250VAC max), making it suitable for both DC and AC control circuits. The sealed SMD housing protects against dust and contaminants, improving durability and operational stability in demanding environments.

As an added advantage, the HFD42-3-3SR is highlighted as a replacement for the Panasonic AGN200A03, offering a reliable alternative for maintenance, upgrades, and new PCB designs.
