A likely pin-compatible replacement with a higher voltage rating; verify mechanical drawings.
The MINTRON MTP125-1203S1 is a standard 2.54mm pitch, 2x3 (6-pin) straight male header. While several alternatives exist, careful verification of row count and electrical ratings is essential for a successful replacement.
Many 6-pin headers are single-row (1x6); must confirm dual-row (2x3) layout.
Some alternatives have lower voltage or current ratings, requiring application review.
2.54mm headers are a common component type with many manufacturers.
Direct replacement for MTP125-1203S1 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use HC-JN254-2-03-Z after confirming its mechanical drawing in the datasheet.
The primary risk is selecting a connector with the wrong physical layout, such as a single-row (1x6) or right-angle version.
