AI replacement insight
Package riskhigh
Housing dimensions, pin length, and PCB footprint must be verified from datasheets.
Electrical risklow
Most candidates match or exceed voltage/current ratings, but some have slightly lower IEC current.
Sourcing risklow
This is a common connector type with multiple sources available.
Can it be replaced directly?
No verified direct replacement is available. Several form-fit-function candidates exist but require engineering review of mechanical drawings and electrical ratings.
Best replacement path
Cross-reference to other manufacturers' vertical 3.81mm headers, such as the DORABO DB2ERC series, after careful datasheet review.
Main risk
Mechanical incompatibility, such as housing size or pin length, despite matching pitch and pin count.
