A form-factor compatible 3-pin header from JST's PH series, but with a lower voltage rating.
ZX-HY2.0-3PZZ is a common 3-pin, 2.0mm pitch through-hole header. Alternatives exist within the JST PH connector family, but require careful verification of voltage ratings and mechanical footprint.
Candidates have a 100V rating vs. target's 250V.
Form-factor is a common standard, but footprint verification is still required.
No direct, drop-in replacement with identical ratings was found. The closest alternatives have a lower voltage rating of 100V, requiring engineering review.
JST B3B-PH-K-S(LF)(SN) is a strong candidate for form and fit, but has a lower voltage rating (100V). If the application tolerates this, it is the best path.
The primary risk is electrical overstress due to candidates having a lower voltage rating (100V) than the target's 250V.

JST's B3B-PH-K-S(LF)(SN) is a strong form-fit match, but its 100V rating is lower than the original's 250V. This makes it a conditional alternative that requires engineering approval.
