Megastar
A through-hole version from the same HY series, offering identical electricals and mating compatibility but requiring a different PCB layout.
ZX-HY2.0-5PWT is a 5-pin, 2.0mm pitch SMT header from Megastar. Finding a direct, pin-compatible replacement is challenging due to mechanical variations between connector series.
Footprint, height, and keying are likely different across series.
Several candidates match the 2A/250V rating.
Multiple vendors offer 2.0mm pitch headers, but finding an exact match is difficult.
No direct drop-in replacement is confirmed. Alternatives exist but require PCB layout verification due to differences in connector series and mechanical footprints.
For board redesigns, use the through-hole version ZX-HY2.0-5PLT. For existing boards, a full mechanical review of any SMT alternative is mandatory.
Mechanical incompatibility is the primary risk. Connector series from different manufacturers, or even different series from the same manufacturer, are rarely footprint-compatible.
