Braun 3000s Replacement Head: 21B, 32B or 32S?

Quick Answer

Braun’s current US service pages list the Braun 3000s Replacement head as 21B, 32B, and 32S. Match the code on the old cassette when it is still readable. For a like-for-like replacement, stay with 21B, 32B or 32S as marked. If the code is missing, the exact 3000s model reference supports all three part families as listed options.

The 32B has a black frame and the 32S has a silver frame. ShaversHead currently sells compatible 32B and 32S options, not 21B. Although Braun lists the 3000s for both 21B and 32B, their cutting designs are described differently, so they should not be presented as identical heads.

Which Replacement Head Fits the Braun 3000s?

The 3000s appears in Braun’s model lists for all three heads. The right purchase still depends on whether you want to preserve the old part number or select another head that Braun lists for the same shaver.

The source for the model match is Braun’s US service listing for 21B, 32B and 32S. These listings establish the 3000s model association. They do not turn every black Series 3 cassette into the same part.

How to Choose the Correct Head in Under a Minute

1. Read the complete shaver model. Look for 3000s on the handle, rating label or original manual. Do not stop at the broader words “Series 3.”
2. Switch the shaver off and remove the old cassette. Follow the model instructions and hold the cassette by its rigid sides rather than pressing the foil.
3. Look for 21B, 32B or 32S. The printed code is a better identifier than color. Both 21B and 32B are black.
4. Use the exact code for a like-for-like purchase. If the old head says 32B, choose 32B; if it says 32S, choose 32S.
5. If the code is unreadable, use the model listing. A confirmed 3000s gives you a documented route to 21B, 32B or 32S. Choose 32B for black or 32S for silver when considering the options ShaversHead currently carries.
6. Check that the offer is a complete cassette. The replacement should include the foil and cutter assembly in its plastic frame, not just an individual foil screen.

If the body does not clearly say 3000s, pause before ordering. A similar-looking Series 3 model or another model beginning with 3 is not enough to apply this decision path.

Can 32B Replace 21B on a Braun 3000s?

Yes, 32B is a listed head for the Braun 3000s: Braun’s current US pages include the model under both 21B and 32B. That makes 32B a documented model fit for a confirmed 3000s, even when an older cassette is marked 21B.

It is not an identical-part claim. Braun describes 21B with two closeness foils, while the 32B description adds a MicroComb. Choose 21B when preserving the old part family matters most. Choose a 32B-compatible replacement when you have confirmed the 3000s model, want a black frame and accept the different part design.

Do not use this as a general rule for every Braun Series 3 shaver. The conclusion follows the exact 3000s entry on Braun’s three service pages.

Should You Choose 32B or 32S for the 3000s?

Choose by the old code when possible, then by finish. Braun lists the 3000s on both service pages, so either part family has a documented model match:

• 32B: black frame
• 32S: silver frame

If the old cassette is marked 32B or 32S, matching it removes one more variable from the order. If the marking has worn away but the handle clearly says 3000s, select the finish that suits the shaver or the option that is available. The dedicated Braun 32B vs 32S comparison explains the two codes in more detail.

Check These Details Before You Order

Once the 3000s model and the 32B or 32S selection are clear, see the compatible Braun Series 3 replacement head page. ShaversHead’s current 32B and 32S choices are compatible replacements, not genuine Braun or OEM parts.

When Should You Replace the Braun 3000s Head?

Braun’s general guidance is to replace the foil-and-cutter block about every 18 months, but the condition of the cassette is the more useful signal. Inspect or replace it sooner when:

• the foil is dented, cracked or perforated;
• the shaver pulls hair after the cassette has been cleaned;
• the same stubble takes noticeably more passes;
• irritation increases despite normal cleaning and correct installation; or
• the cassette sits loose or makes an unusual scraping sound.

Do not shave with a torn foil. If a new head will not sit level or lock onto the shaver, remove it and compare its mounting side with the old cassette. Check the 3000s label and supplied part code again instead of forcing the frame into place.
