AI replacement insight
Electrical riskmedium
Several candidates have a 250V rating, a significant downgrade from the target's 500V.
Package risklow
Most candidates match the through-hole, 2x10, 2.0mm pitch format, but some have shrouds requiring fit checks.
Can it be replaced directly?
No verified direct drop-in replacement has been identified. HCTL's PZ200-2-10-Z is a strong form, fit, and function match, but requires datasheet verification for pinout dimensions.
Best replacement path
PZ200-2-10-Z by HCTL is the strongest candidate, matching key electrical and mechanical specifications. Other options exist but require careful review of voltage ratings.
Main risk
The primary risk is electrical stress; several alternatives have a lower voltage rating (250V vs. 500V). Mechanical differences like shrouds also need checking.
