AI replacement insight
Package riskmedium
All candidates have different housing heights, requiring verification of mating compatibility and clearance.
Electrical risklow
Candidates have matching or superior current and voltage ratings.
Can it be replaced directly?
No direct drop-in replacement has been confirmed. Several alternatives share the same footprint and electrical ratings but differ in housing height, requiring mechanical verification.
Best replacement path
X5511FV-04-C70D30-1000 is the strongest candidate due to its minimal height difference and superior voltage rating. However, all viable alternatives require a mechanical fit check.
Main risk
The primary risk is mechanical incompatibility due to differences in the connector's plastic housing height, which can affect mating and case clearance.
