1. Understanding TSC MH640 and MH641 Printers

TSC MH640 and MH641 belong to TSC's industrial barcode printer family. These models are designed for high-resolution label printing applications where barcode readability, small text clarity and print precision are important.
The MH640 series is known as a 600 dpi high-resolution printer series, suitable for printing small 2D barcodes, graphics, fine text and high-resolution images. TSC-related documentation describes the MH640/MH640T/MH640P series as 600 dpi models designed for ultra-high-resolution printing applications.
The MH641 is also a 600 dpi industrial label printer model. Replacement printhead suppliers commonly list the MH641 printhead as 24 dots/mm, 600 dpi, with part number PH-MH241-0003.
This means MH640 and MH641 are both positioned in the same high-resolution 600 dpi printing category.
2. Are TSC MH640 and MH641 Printheads the Same?
From a technical and aftermarket replacement perspective, MH640 and MH641 printheads are very likely to be the same compatible printhead type.
For example, Barcodes Inc. lists the TSC PH-MH241-0003 printhead module as a 600 dpi printhead compatible with both MH640 and MH641. NeoTech also describes PH-MH241-0003 as a genuine 600 dpi TSC printhead compatible with MH640 and MH641 printers.
At the same time, other suppliers list 98-0600022-02LF as a 600 dpi printhead for the TSC MH640, MH640T and MH640P models.
Therefore, the safe conclusion is:
TSC MH640 and MH641 printheads are generally compatible if the replacement printhead is the correct 600 dpi version and matches the original part number or verified equivalent part number.

3. Key Part Numbers for MH640 and MH641 Printheads
When sourcing a replacement printhead, buyers may see different part numbers depending on the supplier. The most commonly referenced numbers include:
| Printer Model | Resolution | Commonly Listed Part Number | Compatibility Note |
| TSC MH640 | 600 dpi / 24 dots per mm | 98-0600022-02LF / PH-MH241-0003 | Commonly listed in the same 600 dpi printhead group |
| TSC MH641 | 600 dpi / 24 dots per mm | PH-MH241-0003 / 98-0600022-02LF | Frequently listed as compatible with MH640 |
Because different suppliers may use different numbering systems, the model name alone should not be the only basis for purchase. The original printhead label, connector shape and mounting structure should also be checked.
