• [MECHANICAL & BUILD QUALITY] Sealed plastic enclosure with flux-protection construction, flame-retardant grade housing, Silver Alloy (Cadmium-Free, Ag-Alloy) contact material for low contact resistance and long electrical endurance. Subminiature body footprint - Approx. 15.5 x 10.5 x 11.5 mm (0.61 x 0.41 x 0.45 inch) | Approx. 3.5 g (0.12 oz) per relay each relay. Mechanical operating frequency up to 18,000 operations per hour.

Shock resistance: 1,000 m/s squared (mechanical, approx 100G); 200 m/s squared (functional, approx 20G).
• [PIN CONFIGURATION & TERMINAL DESIGN] 5-terminal subminiature SPDT through-hole PCB layout: 5 round through-hole pins arranged in a single row on the bottom of the housing, designed for direct soldering to a control PCB. Standard pin assignment: Pin 1 = Coil A1, Pin 2 = Common (moves between NC and NO when coil energizes), Pin 3 = Coil A2 (no polarity required on DC coil), Pin 4 = NC (Normally Closed, Common rests here when coil de-energized), Pin 5 = NO (Normally Open, Common connects here when coil energized). Compatible with industry-standard 5-pin SPDT subminiature PCB relay pad layouts. Use a temperature-controlled soldering station; do not overheat the housing.
• [CERTIFICATIONS & SAFETY] Certified to UL Recognized Component standard and CSA Certified component standard - these are independent third-party safety certification marks, not brand names. RoHS-compliant lead-free construction. Creepage distance and dielectric strength ratings conform to UL and CSA insulation standards. Built-in coil suppression is not included - add a flyback diode (1N4148 or 1N4007 or equivalent) across the coil input pins (A1 and A2) for DC-driven transistor or MOSFET circuits to protect driver circuitry from back-EMF voltage spikes. Each relay is individually inspected and tested before packaging.
• [TYPICAL APPLICATIONS] Engineered for: low-voltage signal routing on hobby and maker PCBs, instrumentation signal switching, A/V equipment signal relay replacement, security alarm panel relay logic, access control relay circuits, intercom and doorbell control relays, industrial control panel signal switching, PLC discrete output relay replacement, test and measurement equipment signal routing, scientific lab instrument relay replacement, telecom equipment control board relays, microcontroller-driven relay driver boards, low-voltage lighting control logic relays, automotive aftermarket 12V ECU and fuse box relay repair (matching form factor required),
• [SYMPTOMS + DIAGNOSTIC INDICATORS] A failed subminiature signal relay may produce: stuck active state (Common stays connected to either NC or NO regardless of coil drive), stuck open state (Common does not switch when coil is driven), intermittent switching (Common alternates between NC/NO spontaneously, or only switches under vibration or after multiple drive pulses), high coil current draw without contact actuation (shorted coil winding), no coil current draw at rated voltage (open coil winding), contact welding (Common permanently connects to NO after coil de-energizes), high cold contact resistance (oxidized or worn silver-alloy contacts).
• [INSTALLATION TIPS] Disconnect all power from the host circuit before soldering or replacing the relay. If replacing an existing relay, photograph the as-installed PCB orientation and pin footprint first. Match coil voltage (12 VDC), contact form (SPDT, 1 Form C), and 5-pin through-hole layout before installing. Apply a flyback diode (1N4148 or 1N4007) across the coil input pins (A1 and A2, cathode to the more positive coil pin) for transistor or MOSFET DC-driven circuits to suppress back-EMF voltage spikes. Solder PCB through-hole pins with a temperature-controlled soldering station (310 to 340 deg C, no more than 3 to 4 seconds per pin) - do not overheat the housing.
• [COMPATIBILITY NOTE] Industry series designations, form-factor descriptions, and cross-reference identifiers are used only for compatibility verification. Verify the as-shipped contact rating (1A 30VDC / 0.5A 125VAC / 0.3A 60VDC), pin layout (5-pin SPDT through-hole), coil voltage (12 VDC), and dimensions (Approx. 15.5 x 10.5 x 11.5 mm (0.61 x 0.41 x 0.45 inch)) match the G5V-1 specification before ordering. Confirm the coil voltage variant specified by the part number suffix matches your drive circuit before installation. Part number designations
