Type A vs Type F Plugs: Grounding & Voltage Differences & Compatibility

Type A is a 2-pin, ungrounded plug rated 15A at 100-127V, while Type F is a 2-pin, grounded plug rated 16A at 220-240V. The two differ mainly in grounding, voltage, amperage and pin design, which is what decides compatibility — whether a Type A plug fits a Type F socket, and vice versa. Next, check type F vs type L plug.

Key Differences Between Type A and Type F

Here's how Type A and Type F compare, point by point.

  • Grounding: Type A has no grounding. Type F adds a grounding pin or clips to protect against electrical faults.
  • Pin Size and Shape: Type A: Two flat parallel pins (15.9mm apart, 15.9mm long, 6.3mm wide). Type F: Two round pins (4.8mm diameter, 19mm long) with grounding clips on sides.
  • Application: Type A is typically used for heavy-duty appliances such as hair dryers, kettles, and heaters. Type F is typically used for heavy-duty appliances such as hair dryers, kettles, and heaters.

Type A and Type F Compatibility

Type A in Type F Sockets: Generally no. A Type A plug (Two flat parallel pins (15.9mm apart, 15.9mm long, 6.3mm wide)) does not fit a Type F socket (Two round pins (4.8mm diameter, 19mm long) with grounding clips on sides) without a travel adapter.

Type F in Type A Sockets: Generally no. A Type F plug (Two round pins (4.8mm diameter, 19mm long) with grounding clips on sides) does not fit a Type A socket (Two flat parallel pins (15.9mm apart, 15.9mm long, 6.3mm wide)) without a travel adapter.

Does a Type A plug fit into a Type F socket?

Generally no. A Type A plug (Two flat parallel pins (15.9mm apart, 15.9mm long, 6.3mm wide)) does not fit a Type F socket (Two round pins (4.8mm diameter, 19mm long) with grounding clips on sides) without a travel adapter.

Are Type A and Type F plugs the same?

No. Type A follows the NEMA 1-15 standard and Type F follows CEE 7/4 (Schuko) — they differ in grounding, voltage rating.

Which countries use Type A and Type F plugs?

Type A plugs are used in 61 countries, including American Samoa, Anguilla, Antigua and Barbuda, Aruba, Bahamas. Type F plugs are used in 76 countries, including Afghanistan, Albania, Algeria, American Samoa, Andorra. 6 countries use both, including American Samoa, Aruba, Laos, Liberia, Sint Eustatius. Also see type B vs type H plug.

How can you tell a Type A plug from a Type F plug?

A Type A plug has two flat parallel pins (15.9mm apart, 15.9mm long, 6.3mm wide), and is ungrounded. A Type F plug has two round pins (4.8mm diameter, 19mm long) with grounding clips on sides, and is grounded. The quickest tell is the grounding pin or clips — only the grounded one has them.
