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

While several parts like ZX-GH1.25-WT2 and XD-1.25-2PWT share the same form-factor and specifications, true pin-to-pin compatibility is not guaranteed without comparing the mechanical drawings in the datasheets to ensure the PCB layout is identical.

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

The main risk is mechanical incompatibility; you must verify the PCB footprint using the candidate's datasheet. A secondary risk is electrical mismatch; some alternatives may have a lower voltage rating (e.g., 50V instead of 125V), which could damage your circuit.

AI replacement insight

Package riskmedium

While type matches, exact dimensions and pad layout must be verified from datasheets.

Electrical risklow

Several candidates match the 125V/1A rating. Some alternatives have lower ratings and pose a high electrical risk.

Can it be replaced directly?

No drop-in replacement is confirmed without datasheet validation. However, ZX-GH1.25-WT2 and XD-1.25-2PWT are strong form, fit, and functional candidates that should be evaluated.

Best replacement path

ZX-GH1.25-WT2 and XD-1.25-2PWT are strong candidates with matching electrical and mechanical profiles, but require footprint verification.

Main risk

The primary risk is a PCB footprint mismatch, which requires comparing datasheet mechanical drawings.

Recommended alternatives

A strong alternative with matching pitch, orientation, voltage, and current. Footprint verification is required.
