Is there a pin-compatible replacement for PH-2AW?

No pin-compatible replacement has been verified. The key challenge is matching the through-hole, right-angle footprint. All reviewed candidates have different mounting styles (SMT) or orientations.

What risks should I check before replacing PH-2AW?

The main risks are mechanical and electrical. Verify the mounting type (THT vs. SMT), orientation (right-angle vs. vertical), and ensure the substitute's current rating meets or exceeds the original 2A requirement.

PH-2AW Alternatives, Datasheet & Cross Reference | Manufacturer

PH-2AW is a 2-pin, 2.0mm pitch right-angle through-hole header. While direct drop-in replacements are uncommon, several functional alternatives exist that require board layout modifications.

AI replacement insight

Package riskhigh

Requires PCB layout change from THT to SMT.

Electrical riskmedium

Some alternatives have lower current ratings, requiring careful review.

Sourcing risklow

Many functional alternatives are available from major manufacturers.

Can it be replaced directly?

No direct drop-in replacement was identified. All candidates require significant design changes.

Best replacement path

Board redesign for a widely available SMT connector family like the JST PA series.

Main risk

Mechanical incompatibility due to different mounting styles (Through-Hole vs. Surface Mount).

Recommended alternatives

Functionally similar SMT header with higher current, but requires board redesign for SMT and vertical mounting.
