Dr. Pen Cartridge Compatibility Guide (2026): Model-by-Model Chart

Updated August 9, 2026 · Dr. Pen Glow Editorial Team

This page has one job: help you identify the correct replacement-cartridge family for the exact Dr. Pen model you own. Pin count alone does not establish compatibility; connector family comes first.

Already know which cartridge family fits your pen? Use our Dr. Pen Cartridge Pin Count Guide to compare 9, 11, 12, 14, 16, 18, 24, 25, 36 and 42-pin options plus Nano tips before choosing a cartridge type.

Quick Answer: Are Dr. Pen Cartridges Universal?

No. Some devices share a cartridge family, while others use a dedicated connector. Always identify the model printed on the pen or original packaging before ordering replacements.

Three Rules That Prevent Most Compatibility Mistakes

Match the exact model first. “M-series” or “A-series” is not enough.
Connector family matters more than pin count. Two 36-pin cartridges can still use different locks.
Use the live cartridge page as the final check. Accessory ranges and packaging can change.

M8 vs M8S Is the Most Common Mistake

M8 belongs to M8/M7S; M8S belongs to M8S/A8S/A9/A11. They are not interchangeable. See M8 vs M8S for the full explanation.

H5 vs H6 Is Another Separate System

H3/H5 serum-chamber cartridges do not fit H6. H6 has its own replacement family. See H5 vs H6.

Q1S and Bio Pen Q2

Q1S and Q2 currently share a dedicated 9/14/25-pin and Nano family that is separate from standard A-, M- and Hydra-series cartridges. See Q1S vs Bio Pen Q2.

Choosing Pin Count

After compatibility is confirmed, choose only among the options offered for that family. For a full layout comparison, use the Dr. Pen Cartridge Pin Count Guide. This compatibility guide intentionally does not prescribe a pin count for treating scars, wrinkles, pigmentation or other medical concerns. Pin count is a product-format choice; suitability depends on device instructions and professional guidance.

Hygiene

Needle cartridges should be single-use. Keep each cartridge sealed until use, do not share it, and dispose of it after the session according to applicable local guidance.
