High-quality functional match from JST, but requires PCB change from SMT to Through-Hole.
Finding a substitute for the 2.54-5PWTDK SMT header requires careful review. While no direct drop-in replacements were found, several through-hole functional alternatives exist.
Candidate is Through-Hole, target is SMT. Requires PCB redesign.
Key electrical parameters like voltage, current, and pitch match.
No direct SMT drop-in replacement was identified. All viable alternatives require PCB layout changes due to different mounting styles (Through-Hole vs. SMT).
Consider through-hole right-angle headers like JST's S5B-XH-A series if your PCB design can be adapted.
The primary risk is mechanical incompatibility; the target is Surface Mount (SMT) while all viable alternatives are Through-Hole, requiring a board redesign.
