A strong alternative with matching key electricals and 27.5mm lead pitch, pending datasheet verification.
Finding a substitute for the KYET PX225K2C2705 involves matching its 2.2µF capacitance, 310VAC rating, and critical 27.5mm lead pitch. This page analyzes potential alternatives for your application.
Key electricals (capacitance, voltage, tolerance) are matched by several candidates.
Lead pitch is a critical parameter. Only one candidate (MPX225K31F2KN20800) appears to match the target's 27.5mm spacing.
A direct, pin-for-pin replacement is likely available with MPX225K31F2KN20800, but requires verification of its physical dimensions from the datasheet before procurement.
The KNSCHA MPX225K31F2KN20800 is the most promising replacement path, offering matching electrical specifications and a 27.5mm lead pitch.
The primary risk when substituting is a mechanical mismatch in lead pitch. Several candidates are electrically similar but will not fit the PCB layout.

| Feature / factor | PX225K2C2705 | MPX225K31F2KN20800 | PX225K2C2203 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Capacitance | 2.2 µF | 2.2 µF | 2.2 µF | 2.2 µF — Capacitance matches.; PX225K2C2203: Capacitance matches. | |
| Voltage | 310 VAC | 310 VAC | 310 VAC | 310 VAC — Voltage rating matches target's requirement.; PX225K2C2203: Voltage rating matches. | |
| Tolerance | ±10% | ±10% | - | ±10% — Tolerance matches. | |
| Package | Radial, 27.5mm Lead Pitch | Radial, P=27.5mm | Radial, 22.5mm Lead Pitch | Radial, P=27.5mm / Radial, 22.5mm Lead Pitch — Lead pitch appears to match target's 27.5mm.; PX225K2C2203: Lead pitch is smaller and will not fit without board modification. | |
| Application | X2 | X2 | X2 | X2 — Both are X2 class safety capacitors.; PX225K2C2203: Both are X2 class safety capacitors from the same manufacturer. |
The best alternative identified is MPX225K31F2KN20800 from KNSCHA. It matches the key electrical specs and, most importantly, the 27.5mm lead pitch.
