Is there a pin-compatible replacement for 1.25-2PLTDK?

Currently, no pin-for-pin compatible vertical SMT replacement has been verified. Available alternatives have different orientations (right-angle) or mounting types (through-hole), which are not drop-in compatible and require design changes.

What risks should I check before replacing 1.25-2PLTDK?

The main risk is mechanical incompatibility. You must check the connector's orientation (vertical vs. right-angle) and mounting type (SMT vs. through-hole) to ensure it fits your PCB layout and enclosure.

1.25-2PLTDK Alternatives, Datasheet & Cross Reference | SHOU HAN

Finding a substitute for the SHOU HAN 1.25-2PLTDK, a 2-pin 1.25mm pitch vertical SMT header, requires careful review. While no direct pin-compatible vertical replacements were found, several functional alternatives with different orientations exist.

AI replacement insight

Package riskhigh

Orientation and/or mounting type differ from the target, requiring PCB layout and enclosure verification.

Electrical risklow

Key electrical parameters like voltage and current match on several candidates.

Can it be replaced directly?

No direct, drop-in replacement was found. All suitable candidates require design review due to form factor differences, primarily connector orientation.

Best replacement path

Use a right-angle SMT alternative like WAFER-MX1.25-2PCB if the mechanical design allows for a change in orientation.

Main risk

Mechanical form factor mismatch, specifically the connector orientation being right-angle instead of vertical.

Recommended alternatives

Functionally similar with matching pitch and electricals, but has a right-angle orientation instead of vertical.
