Silicon Carbide Igniters & Assemblies
Compare silicon carbide igniter configurations by element form, ceramic base, mounting hardware and connection. Find a starting configuration for your equipment, then match the hot-zone position, electrical drive and supplied parts.
Explore SiC hot surface igniter elements, wired assemblies and defined kits for replacement-parts sourcing and drawing-based OEM projects.
What Is Silicon Carbide Igniter?
A silicon carbide igniter is a type of hot surface igniter (HSI) that uses an electrically heated silicon carbide element to ignite a gas burner. When current passes through the element, its surface heats to the temperature needed for ignition. Depending on the equipment design, the igniter may be supplied as an element or an assembly with a ceramic base, lead wires, connectors and mounting hardware.
CONFIGURATION OPTIONS
Choose by application, mounting and connection
Use the installed equipment and original reference first, then review the element form, ceramic body, bracket or gasket, leads, terminals and quoted package contents.
Boiler and furnace
Terminal-lead igniter assembly
Insulated leads terminate in separate female terminals; the ceramic body establishes the mounting interface.
Before selection: terminal size, lead length, body orientation, hot-zone position and electrical requirements.
Water heater
Cylindrical flange-mount assembly
A cylindrical slotted element projects from a tubular ceramic holder with a metal mounting flange and a plug-connected lead set.
Before selection: equipment version, mounting flange, ceramic holder, lead length, plug interface and hot-zone location.
Equipment and OEM projects
Bracketed terminal-lead assembly
An angled metal bracket surrounds the ceramic holder, while the insulated leads end in separate terminals.
Before selection: drawing, bracket holes and orientation, terminal interface, included parts, electrical conditions and acceptance criteria.
Boiler
Flanged terminal-lead boiler igniter
A ceramic mounting flange, flat element and individually terminated insulated leads define this arrangement.
Original equipment references
- Lochinvar original parts 100165937 and PLT3400
Before selection: complete boiler model, terminal type and size, mounting position, lead routing and supplied parts.
Gas dryer
Bracket-kit igniter arrangement
The element, connector and several bracket forms illustrate why installed hardware must be identified separately.
Original equipment references
- Speed Queen / Alliance original part D510184P
- Speed Queen / Alliance equipment model CTSA9AWN
Before selection: complete appliance model and suffix, selected bracket, connector, fasteners and kit contents.
Pool and spa heater
Gasket-mount igniter assembly
A broad ceramic mounting face is shown with a separate gasket pad and individually terminated insulated leads.
Original equipment references
- Jandy original part R0317200
Before selection: gasket outline, mounting interface, insertion depth, terminals, voltage and control conditions.
Oven and range
Oven channel-bracket assembly
A vented metal channel and insulated leads represent an oven-specific mounting and routing arrangement.
Original equipment references
- Bosch original parts 00487383 and 00492431
Before selection: complete appliance model, bake or broil position, bracket, leads, terminals and electrical conditions.

Silicon Carbide Igniter Properties
Silicon carbide igniter performance depends on heat-up response, electrical resistance stability and durability during repeated heating and cooling cycles. These characteristics are evaluated under the intended power supply, airflow and mounting conditions.
💡 Quick Selection Guide:
Electrical fit: Confirm element voltage and ignition controller requirements.
Mechanical fit: Match mounting dimensions and hot-zone position.
Supply scope: Specify leads, connectors and mounting hardware.

APPLICATIONS
Silicon carbide igniters by equipment application
Use the application to narrow the checks, then compare the physical configuration and controls.
Boilers and furnaces
Start with the complete equipment version, original part, mounting position, terminal type and hot-zone location.
Gas dryers
The appliance suffix, bracket, connector and listed kit contents separate otherwise similar-looking assemblies.
Water heaters
Review the element and tubular ceramic holder, flange, plug interface and electrical/control conditions.
Pool and spa heaters
Gasket outline, mounting pattern, insertion depth and terminal arrangement are core selection details.
SELECTION GUIDE
What to match before choosing an igniter
Use this checklist with the installed part, equipment information or a new assembly drawing.
| Selection area | What to compare | Why it matters |
|---|---|---|
| Part and equipment identity | Original part number; complete equipment model, suffix and region; controller or ignition module. | Keeps similar-looking versions separate. |
| Hot zone and mounting | Element geometry; mounting datum; hole pattern; insertion depth; distance and angle to the burner. | Checks where the active element will sit. |
| Connection and leads | Lead length and temperature rating; terminal size or connector keying; routing and strain relief. | Checks the electrical and mechanical interface. |
| Electrical drive | Voltage at the element; AC/DC; frequency or waveform; starting and operating current; controller limits. | Matches the actual power and control conditions. |
| Resistance and heat-up | Cold resistance with measurement temperature; resistance–temperature curve; target temperature and heat-up test conditions. | Makes resistance and heat-up comparisons meaningful. |
| Supply scope | Element only, wired assembly or kit; bracket, gasket, fasteners and quantities; drawing and BOM revision. | Defines what is included in the order. |
| Duty and acceptance | Fuel and airflow; ignition sequence; on/off and cooling conditions; environment; sample acceptance criteria. | Connects the configuration to the intended operating system. |

SOURCING QUESTIONS
Silicon carbide igniter FAQs
No. It identifies a useful starting reference. The complete equipment version, mounting, connector, hot-zone position, electrical conditions and supplied parts still require review.
State whether the request covers the element only, a wired assembly, or an explicit bill of materials that names every bracket, gasket, connector and fastener.
A change from SiC to silicon nitride requires review of the complete igniter and control system. Similar appearance or the same voltage label does not establish a direct replacement.
Specify every required component in the request: element, base, leads, connector, bracket, gasket and fasteners. The quotation and bill of materials define the supplied assembly or kit; the photograph alone does not define its contents.
Provide the drawing revision, mounting envelope, connector or terminal requirement, electrical and control conditions, quantity and acceptance criteria.
