What Is the Omron G8P-1C4TP Power Relay?

The Omron G8P-1C4TP-24VDC is a high-capacity PCB/pannel-mount SPDT power relay from Omron's G8P series. With contacts rated for 30A at 250VAC (or 30A at 30VDC), this relay bridges the gap between control-level signal relays and full-size contactors. It is commonly found in appliances (air conditioners, washing machines, microwave ovens), HVAC control boards, industrial control panels, and power supply circuits. The "1C" designation indicates SPDT (one set of changeover contacts), and "4TP" refers to the specific terminal and mounting configuration. This listing is for a 5-piece pack — replacing all relays of the same type in a multi-relay board at once, which is good preventive maintenance practice.

In short: A 5-pack of Omron G8P-1C4TP 24VDC SPDT 30A power relays. If your appliance or control board uses these relays and one has failed, replacing all of them (not just the failed one) eliminates the risk of another failure in the near future — the other relays on the same board have the same number of switching cycles on them.

Why Bulk Replacement Makes Sense for Aged Relay Boards

In any equipment with multiple identical relays — an HVAC control board with a compressor relay, a fan relay, and a reversing valve relay, for example — all relays have been subjected to roughly the same number of switching cycles and the same operating environment (temperature, humidity, voltage transients). When one fails, the others are statistically near the end of their service life. Replacing all relays at once costs more in parts but saves the labor of a second (or third) service call and prevents the inconvenience of cascading failures. For critical equipment, a full relay replacement during scheduled maintenance is standard industry practice.

Frequently Asked Questions

How do I desolder and replace PCB-mount relays without damaging the board?

The G8P-1C4TP may be mounted via PCB pins or quick-connect terminals — check your specific board. For PCB-mount relays, use a temperature-controlled soldering iron (350-370 degrees C) with a chisel tip. Apply fresh solder to each joint before attempting removal (this reduces the melting point of the old oxidized solder). Use a manual solder sucker or desoldering braid to remove solder from each pin. Do NOT pry the relay off the board while pins are still soldered — you will lift the PCB pads. Once all pins wiggle freely, the relay should drop out. Clean the through-holes with desoldering braid before inserting the new relay.

Can I substitute a different relay if the exact G8P-1C4TP is not available?

Electrically, any relay with the same coil voltage (24VDC), the same or higher contact rating (30A/250VAC), and the same contact form (SPDT) may be functionally compatible. However, the mechanical footprint — pin spacing, terminal type, and overall dimensions — must match exactly for PCB mounting. A relay that is electrically identical but has a different pin layout will not fit the PCB. Cross-reference the G8P-1C4TP pinout with the datasheet of any proposed substitute. When in doubt, replacing with the exact original part number avoids surprises.

Is this an authentic Omron product?

Yes. Every Omron product we supply is sourced through Omron's authorized distribution network and is guaranteed genuine. Counterfeit Omron relays are a known problem in the market — they may look identical externally but use inferior contact materials that weld or erode prematurely, undersized coil wire that overheats, or substandard plastic housings that deform under normal operating temperatures. Genuine Omron relays have consistent laser marking, a date code, and the Omron logo molded into the housing.
