Near-identical part from the same manufacturer, likely differing only in color or packaging.
ZX-HA2.54-2PZZ-Y is a 2-pin, 2.54mm pitch straight male header from Megastar. When seeking alternatives, focus on matching the 3A current rating, straight through-hole mounting, and pin dimensions.
Cross-vendor parts require verification of mechanical drawings for pin-to-pin compatibility.
Several alternatives match the 3A/250V rating, but some have lower current ratings and must be avoided if the load is >2A.
Direct replacement for ZX-HA2.54-2PZZ-Y should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use Megastar ZX-HA2.54-2PZZ-R for a near-identical part or HANBO WAFER-XH254Z-2AM for a strong cross-vendor option.
The primary risk when substituting is a mismatch in current rating or mechanical dimensions, such as pin size or housing shape.
