Strong functional alternative with a different mounting type (SMT) but matching all key electrical specs.
Best Alternatives to 1.0-4PS
The DEALON 1.0-4PS is a 4-pin, 1.0mm pitch vertical through-hole header. While no direct drop-in replacements have been identified, several functional alternatives with a Surface Mount (SMT) package are available, offering similar electrical performance but requiring a PCB layout modification.
AI replacement insight
Package riskhigh
Target is Through-Hole, all candidates are SMT. A PCB redesign is mandatory.
Electrical risklow
Most candidates match the 1A/50V rating, but one is a downgrade (0.7A) and requires review.
Can it be replaced directly?
Direct replacement for 1.0-4PS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
If a PCB redesign for an SMT component is feasible, consider the A1002WV-S-4P from CJT as it matches key electrical specifications and orientation.
Main risk
The primary risk is mechanical incompatibility. All candidates are SMT and cannot be installed on a board designed for the through-hole target without a layout change.
