TSC ML240 vs MA2400 Printhead: Are They the Same and Interchangeable?
Quick Conclusion
The TSC ML240 printhead and TSC MA2400 printhead can usually be treated as the same replacement part only when the printer is the 203 dpi version and the printhead part number matches.
In the replacement market, the commonly listed compatible part numbers include:
| Printer Model | Resolution | Common Printhead Part Number | Compatibility Judgment |
| TSC ML240 / ML240P | 203 dpi / 8 dots per mm | PH-ML240-0003, 98-0800022-01LF, 98-0800022-02LF | Compatible within the same 203 dpi group |
| TSC MA2400 / MA2400P | 203 dpi | 98-0800022-01LF / 98-0800022-02LF commonly listed | Usually compatible with ML240 203 dpi printhead |
| TSC ML340 / ML340P | 300 dpi | PH-ML240-0004 / alternative PH-ML240-0002 | Not interchangeable with ML240 203 dpi printhead |
The key point is simple: do not judge compatibility by printer name alone. Confirm the DPI, connector, bracket structure, and part number before installation.
Are TSC ML240 and MA2400 the Same Printer?
No. ML240 and MA2400 are not necessarily the same printer model name, but they belong to a very close TSC industrial barcode printer family in terms of print mechanism design and replacement parts.
The ML240 parts list identifies PH-ML240-0003 as "PRINTHEAD ASSY, ML240", while PH-ML240-0004 is listed separately for ML340. This confirms that TSC separates 203 dpi and 300 dpi printhead assemblies under the ML240/ML340 platform.
For MA2400, market listings commonly identify the printhead as compatible with TSC MA2400 / MA2400P / ML240 using part numbers such as 98-0800022-01LF or 98-0800022-02LF. Codewel's own product data also lists 98-0800022-01LF as compatible with TSC ML240 and MA2400 series, with 203 dpi / 8 dots per mm resolution and 104 mm print width.
Are the ML240 and MA2400 Printheads Interchangeable?

Yes, in most cases, the ML240 and MA2400 printheads are interchangeable when both are 203 dpi models and use the same part-number family.
The most important matching conditions are:
| Check Point | Required Condition |
| Resolution | Must be 203 dpi / 8 dots per mm |
| Print width | Around 104 mm / 4.09 inches |
| Part number | 98-0800022-01LF, 98-0800022-02LF, or equivalent PH-ML240-0003 assembly |
| Physical structure | Same bracket, mounting holes, cable connector, and print line position |
| Printer firmware/settings | Head resistance and print darkness should be adjusted after replacement |
A practical way to understand it: ML240 and MA2400 may use different commercial model names, but the 203 dpi printhead module can share the same replacement specification.
What Is the Main Risk?
The main risk is confusing 203 dpi ML240 / MA2400 printheads with 300 dpi ML340 / MA3400 printheads.
The ML240 parts list clearly separates the printhead assembly for ML240 from the ML340 printhead assembly: PH-ML240-0003 for ML240 and PH-ML240-0004 for ML340.
That means a 300 dpi printhead should not be installed into a 203 dpi printer as a simple replacement. Even if the shape looks similar, the dot density, resistance, print alignment, and printer control settings are different.

Why Do Some Sellers List ML240, MA2400, ML340, and MA3400 Together?
In the aftermarket, some listings combine several printer names to increase search visibility. This can be misleading.
For purchasing accuracy, buyers should not only read the model title. They should check:
- The exact printer model label.
- The old printhead part number.
- The DPI printed on the printer or shown in the printer configuration.
- The connector and bracket photo.
- Whether the replacement is a full printhead assembly or only the bare thermal element.
For example, a listing may include "ML240 / MA2400 / ML340 / MA3400," but the actual part may only be correct for the 203 dpi group or the 300 dpi group, not both.
Final Verdict
The TSC ML240 and MA2400 printheads are usually compatible in the 203 dpi version, especially when the replacement part number is 98-0800022-01LF / 98-0800022-02LF / PH-ML240-0003.
However, they should not be blindly treated as universal across the whole ML/MA family. ML340 or MA3400 300 dpi printheads are different and should not be mixed with ML240 / MA2400 203 dpi printheads.
For buyers, the best verification method is to match printer model + DPI + old printhead part number + physical connector + bracket structure before ordering.
