Is there a pin-compatible replacement for HC-1.25-3AW?

No pin-compatible, drop-in replacements were identified. All candidates reviewed had a mismatch in either mounting style (SMT vs. Through-Hole) or orientation (Vertical vs. Right-Angle).

What risks should I check before replacing HC-1.25-3AW?

The main risk is mechanical incompatibility. Verify the mounting type (Through-Hole vs. SMT) and orientation (Right-Angle vs. Vertical). An incorrect form factor will not fit your existing PCB layout.

HC-1.25-3AW Alternatives, Datasheet & Cross Reference | HCTL

HC-1.25-3AW is a 3-pin, 1.25mm pitch right-angle through-hole header. Finding a direct drop-in replacement requires matching the exact mechanical footprint and orientation.

AI replacement insight

Package riskhigh

Candidates have different mounting types (SMT) or orientation (Vertical), preventing a drop-in fit for the Through-Hole Right-Angle target.

Electrical risklow

Several candidates match the target's 1A, 125V rating.

Can it be replaced directly?

No direct drop-in replacement was found. All candidates have a different mechanical form factor (mounting type or orientation).

Best replacement path

Functional alternatives requiring board redesign.

Main risk

Mechanical incompatibility due to different mounting type (SMT vs. Through-Hole) or pin orientation.

Recommended alternatives

Functionally similar SMT right-angle header with matching electrical ratings; not a drop-in replacement.
