Pepper X sits at the absolute ceiling of documented heat — 2,693,000 to 3,180,000 SHU — making it one of the hardest peppers to replace like-for-like. Whether you can't source it or simply need something more available, the substitutes below cover the same scorching territory with similar fruity and earthy flavor profiles. None will match Pepper X exactly, but the right pick depends on how close you need to get on heat and whether flavor nuance matters for your recipe.
These alternatives are ranked by how closely they match Pepper X’s heat level and flavor profile. Use the conversion ratios to adjust quantities in your recipe.
#1
Dragon's Breath Closest Match
Dragon's Breath clocks in at 2,480,000-2,500,000 SHU — the closest any documented pepper gets to Pepper X's upper range. Flavor-wise, it skews intensely hot with less of the earthy depth that defines Pepper X, but the sheer capsaicin load makes it the most direct swap when raw heat is the primary goal.
Conversion: use 1:1 by weight. If your recipe relies on Pepper X's earthy undertone, add a small pinch of smoked paprika to compensate.
#2
Carolina Reaper Runner-Up
Before Pepper X was measured, the Carolina Reaper's fruity, scorching character held the world record. At 1,400,000-2,200,000 SHU, it tops out roughly 1 million units below Pepper X's ceiling, but its sweet-fruity flavor is arguably the closest flavor match on this list.
Conversion: use 1.25:1 (slightly more Reaper to approximate Pepper X's heat). Both are C. chinense cultivars, so the base flavor chemistry is similar. For a direct heat comparison, the side-by-side heat gap between these two is worth reviewing before you commit to a ratio.
#3
Komodo Dragon Pepper Also Great
The Komodo Dragon's intensely fruity burn lands at 1,400,000-2,200,000 SHU — identical range to the Reaper but with a slightly more aggressive, less sweet character. It's a strong choice when you want Pepper X's fruity notes without the Reaper's candy-sweet edge.
Conversion: 1.25:1 by weight. Works particularly well in hot sauces where the fruit forward heat can build gradually.
#4
Trinidad Moruga Scorpion
At 1,200,000-2,009,231 SHU, the Trinidad Moruga Scorpion's floral, fruity heat is one of the more complex options here. The floral note adds a dimension Pepper X lacks, which can either enhance or distract depending on your application.
Conversion: 1.5:1. Best used in sauces and marinades where the floral character has room to integrate rather than dominate.
#5
Chocolate Bhutlah
The Chocolate Bhutlah's deep smoky intensity ranges 1,500,000-2,000,000 SHU and brings something none of the other substitutes offer: a pronounced smokiness that pairs naturally with Pepper X's earthy quality. If the recipe leans savory, this is worth serious consideration.
Conversion: 1.25:1. The smoke can amplify earthy notes in meat-based dishes, making it a surprisingly apt match for Pepper X's flavor profile even if it falls short on raw SHU. These peppers belong to the super-hot heat category alongside Pepper X, so the culinary context is identical.
#6
7 Pot Douglah
The 7 Pot Douglah's nutty, earthy heat runs 1,200,000-1,853,986 SHU and is the most flavor-compatible option for Pepper X's earthy side. The nutty quality is unique among super-hots and complements earthy applications — think chili, dry rubs, and fermented hot sauces.
Conversion: 1.5:1 to compensate for the lower SHU ceiling. This is the substitute to reach for when flavor alignment matters more than matching heat exactly. It also represents the broader American pepper tradition of pushing cultivars toward extreme heat with complex flavor.
#7
Trinidad Scorpion Butch T
Rounding out the list, the Trinidad Scorpion Butch T's fiercely fruity heat sits at 1,463,700-1,500,000 SHU — the lowest ceiling of any substitute here, but still roughly 600 times hotter than a jalapeño. Its fruity intensity holds up well in small-batch hot sauces and spice blends where you need super-hot character without the sourcing headache of rarer varieties.
Conversion: 1.75:1. At this ratio, the heat contribution approaches Pepper X's lower range, though the flavor will be fruitier and less earthy.
Habanero seems like a logical step-down substitute, but at 100,000-350,000 SHU it falls so far below Pepper X's floor that no practical conversion ratio bridges the gap — you'd need so much habanero that the flavor would overwhelm any dish before the heat even registers comparably.
Ghost Pepper (Bhut Jolokia) sits at around 1,000,000 SHU and shares the C. chinense family, but its thin flesh and distinctly smoky-sweet flavor profile diverges sharply from Pepper X's fruity-earthy character. The heat gap is also significant enough that recipes calibrated for Pepper X will read as noticeably milder.
Scotch Bonnet, despite being a close botanical relative, caps out around 350,000 SHU and brings a tropical sweetness that clashes with Pepper X's earthy depth. It's an excellent pepper in its own right, but not a credible stand-in for anything in the super-hot tier.
Substitution Tip
When substituting Pepper X (2.7M–3.2M SHU), always start with less of a hotter substitute and add more to taste. For milder substitutes, you can increase the quantity.

Dragon's Breath at 2,480,000-2,500,000 SHU is the nearest documented match to Pepper X's lower heat range. Use it at a 1:1 ratio, though expect slightly less of the earthy flavor depth that defines Pepper X.
Yes — the Carolina Reaper is the best all-around swap for hot sauce applications because its fruity-sweet flavor profile overlaps meaningfully with Pepper X's fruity notes. Use a 1.25:1 ratio (more Reaper by weight) to compensate for the lower SHU ceiling.
At its peak measurement of 3,180,000 SHU, Pepper X is roughly 1,000 times hotter than an average jalapeño (2,500-8,000 SHU). Even its lower bound of 2,693,000 SHU puts it in an entirely different heat category than any mainstream grocery store pepper.
The 7 Pot Douglah is the strongest match for earthy applications — its nutty, earthy flavor profile directly mirrors that dimension of Pepper X. The Chocolate Bhutlah is a close second if you also want a smoky quality in the finished dish.
Most are C. chinense, the same botanical family as Pepper X, which is why they share fruity flavor characteristics. Dragon's Breath is the notable exception, though it still delivers comparable heat intensity for applications where raw Scoville output matters most.
