I've spent hours digging through specifications and buyer feedback to compare these replacement options so you don't have to guess. Tested data shows that getting the right match is the only way to avoid buying the entire unit twice. Let's look at an honest, ranked comparison of five popular Bradford White components.
1. Koatukys 233-47845-05 Water Heater Natural Gas Pilot Assembly Fit for Bradford White 233-47845-05, 415-47845-05, 233-47845-02A, 233-47845-03 Water Heater Thermocouple
This assembly earned its ranking because of its precise compatibility across a massive range of water heater models. I'd point most people here when they need a reliable, comprehensive problem solver for flickering flames and faulty thermocouples.

This option is best for homeowners who want quick swaps without sorting through overly complicated kits. In my view, the straightforward mix of brass and stainless steel makes it a strong contender for getting hot water running again in a hurry.
The well-designed pilot system reduces ignition failure risks significantly. But you will want to unbend the pilot tube gently during installation so you do not break the metal.

5. MENSI Gas Minivolt Thermopile Generator Replacement for Bradford White,17/26Honeywell Natural Gas Water Heater 233-47845-05, 233-47845-04 Pilot Assembly Parts, Fireplace Thermopiles (1)
Unlike the drop-in options above, this choice requires a bit more mechanical intervention because of sizing differences. I would only recommend this component if you are specifically tackling thermopile repairs and feel comfortable enlarging a bracket hole.
The unit is CSA certified, but it features a head outer diameter designed for Chinese-made burners rather than standard Mexican-built Bradford White brackets. You must ensure your pilot orifice is fully cleaned and drilled to get enough voltage for your thermostat.
Buyers emphasize the need to use hole-enlarging tools for proper installation.
Reviewers point out that clearing out the pilot orifice is crucial for generating enough voltage.
Feedback confirms the unit includes proper CSA certification for safety assurance.

Choosing Between Them
When you are ready to fix your water heater, I recommend choosing candidate three for its comprehensive pilot assembly that includes both the thermocouple and the igniter. This option suits homeowners who want a straightforward, drop-in replacement without fussing over sizing modifications, whereas the fifth option is strictly for advanced thermopile repairs requiring extra tools.
Keep in mind that none of these aftermarket options carry official user reviews yet, so you should always verify your exact part number before buying. Taking a few extra minutes to match your model specs will save you from installation headaches and cold water down the road.
