Functional alternate with a higher 6kV rating, but different lead spacing requires review.
Reviewing alternatives for the STE T07E3E102MA5B0S0N0, a 1nF 4kV radial capacitor. While several parts offer similar electrical specs, matching the 7.5mm lead spacing is critical for a drop-in replacement.
Lead spacing mismatch prevents drop-in replacement.
Candidates offer matching or superior electrical specs, but dielectric changes require review.
No direct pin-compatible replacement was found among the candidates due to a lead spacing mismatch (10mm vs. target's 7.5mm).
Functional alternates with higher voltage ratings exist, but all reviewed candidates have a 10mm lead spacing, requiring mechanical adjustment.
The primary risk is mechanical incompatibility. The lead spacing of all viable candidates differs from the target, preventing a direct drop-in replacement.

Functional alternate with a higher 6kV rating, but different lead spacing requires review.
