HCR 4141 is a higher flammability refrigerant blend with each component in the A3 Safety Group. HFO-1234ze(E) and R-516A are lower flammability refrigerants, both in the A2L Safety Group. | https://referencesource.org/hvac-component-refrigerant-compatibility/r-516a/ | [

HVAC refrigerant replacements: retrofit compatibility, safety class, GWP and lubricant
Canonical, always-current version: https://referencesource.org/hvac-component-refrigerant-compatibility/ Machine-readable: https://referencesource.org/hvac-component-refrigerant-compatibility/data.json — this mirror is a point-in-time copy.
- Last verified: 2026-08-11
- Stale after: 2027-08-11 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
- Records: 109
Which refrigerant substitutes for which in air conditioning, heat pump and refrigeration equipment, drawn from the EPA SNAP substitutes list, compressor-manufacturer bulletins (Copeland) and refrigerant-manufacturer replacement guides (Chemours, Honeywell, Arkema). Each record carries the ASHRAE safety classification, GWP, whether the substitute is approved for retrofit or new equipment only, and the compatible lubricant. Answers 'can I put R-454B in an R-410A system', 'what replaces R-22 without changing the oil', and 'is this substitute EPA-acceptable' — questions where the wrong answer damages equipment or breaks federal rules.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
Licence position
Factual compilation with source citations. EPA SNAP substitute listings are US government work (public domain). Manufacturer figures (Copeland, Chemours, Honeywell, Trane, Arkema) are facts taken with short attributed quotes linking back to the published guide.
Facts are not copyrightable; what this dataset takes from each source is a fact plus a short attributed quote linking back to the page that states it.
