Mazda 185q-w2-g10 May 2026

If you are replacing a unit or designing a hydraulic manifold, these OEM specifications are non-negotiable.

The Mazda 185Q-W2-G10 is often cross-referenced with: mazda 185q-w2-g10

Warning: While the mounting pattern (NG10 / CETOP 7) is identical across these brands, the spool overlap is different. Substituting a Rexroth valve for a Mazda 185Q-W2-G10 will likely cause cylinder jerking due to the "W2" unique closed-center overlap. Always test with a flow meter before full deployment.

| Parameter | Spec | |-----------|------| | Operating Voltage | 12V DC (nominal) | | Current Rating per Terminal | Typically 5-8A for 0.64mm; 10-15A for 1.5mm | | Temperature Range | -40°C to +125°C (engine bay); -40°C to +85°C (interior) | | Mating Cycle Durability | 10+ cycles (service life) | | Terminal Plating | Tin (standard) or gold (for low-voltage signals) | | Harness Wire Gauge | 0.3mm² to 0.85mm² (AWG 22-18) | If you are replacing a unit or designing

To ensure compatibility, your replacement must match the following critical parameters of the Mazda 185Q-W2-G10. If you have a failed unit, compare it to the list below:

| Specification | Detail | |---------------|---------| | Lamp Type | Quartz Halogen (Tungsten-Halogen) | | Nominal Voltage | 12V – 24V DC (Verify with meter; common is 15V or 22.8V) | | Wattage | 180W – 185W (Most common) | | Luminous Flux | Approx. 4,000 – 5,000 lumens (depending on voltage) | | Color Temperature | 3,200K – 3,400K (Warm white, ideal for optical contrast) | | Average Rated Life | 50 – 200 hours (High-output version) | | Base Type | G10 (Bi-pin, 10 mm spacing) | | Filament Type | C-8 (Coaxial, for even light distribution) | | Cooling Requirement | Forced air (fan cooling) mandatory | | Orientation | Horizontal ±15° (unless marked otherwise) | Warning: While the mounting pattern (NG10 / CETOP

Important: Many users confuse the "W2" code with a voltage rating. In Toshiba/Mazda’s naming convention, "W2" dictates the pinch seal and filament support structure. Do not substitute based solely on voltage—pinching the wrong bulb can shatter the quartz envelope.
