Is there a pin-compatible replacement for MX128-2.54-04P-GN01-Cu-Y-A?

XY308-2.54-4P and DB141V-2.54-4P-GN are likely form-fit compatible, but are not guaranteed to be pin-to-pin without verifying the complete mechanical drawing and footprint in the datasheets against your PCB layout.

What risks should I check before replacing MX128-2.54-04P-GN01-Cu-Y-A?

Before replacing, check three key things: 1) The substitute's operating temperature range meets or exceeds the target's -40°C to +105°C. 2) The accepted wire gauge (e.g., 26-18 AWG) is suitable for your application. 3) The physical dimensions and PCB footprint from the datasheet match your design.

AI replacement insight

Electrical risklow

Voltage and current ratings are standard and easily matched.

Package riskmedium

While pitch and positions match, overall housing dimensions and pin diameter must be verified from datasheets to ensure mechanical fit.

Sourcing risklow

This is a common connector type with multiple manufacturers.

Can it be replaced directly?

No drop-in replacement has been verified. However, parts like XY308-2.54-4P are strong candidates that match most key parameters and require minimal engineering review.

Best replacement path

Use a functional alternative like XY308-2.54-4P or DB141V-2.54-4P-GN after verifying datasheet for temperature range and footprint.

Main risk

The primary risk is a mismatch in operating temperature range or minor differences in physical footprint, which could affect PCB layout and long-term reliability.

Recommended alternatives

A 4-position, 2.54mm pitch terminal block with matching voltage and current ratings; review datasheet for temperature range.
