HCTL
A minor part number variant from the same manufacturer, likely a direct drop-in replacement.
Find reliable alternatives for the HCTL HC-XHB-2A, a 2-pin 2.5mm pitch straight header. This guide reviews pin-compatible options and functional alternatives, highlighting key differences.
The 3A/250V rating is standard for this connector series.
Cross-vendor parts require PCB footprint verification from datasheets.
This is a very common connector type with many manufacturers.
Direct replacement for HC-XHB-2A should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with HC-XH-2A-G by HCTL. If unavailable, evaluate cross-vendor XH-series straight TH headers like Megastar's ZX-XH2.54-2PZZ-R after verifying the footprint.
Mechanical footprint mismatch. While many 'XH 2.5mm' connectors are interchangeable, slight variations in housing or pin dimensions can cause assembly issues.
