AI replacement insight

Package riskmedium

Pin length and housing dimensions must be verified for pin-to-pin compatibility.

Electrical risklow

Most alternatives have comparable or better ratings, but some are downgrades.

Can it be replaced directly?

Yes, MTP125-1104S1 is a likely pin-to-pin replacement for 640454-4, pending datasheet verification of pin lengths and housing dimensions.

Best replacement path

MTP125-1104S1 by MINTRON is the strongest candidate, matching key mechanical and electrical specs, but requires dimensional verification.

Main risk

The primary risk is mechanical incompatibility, either from different housing styles (e.g., XH series) or subtle dimensional differences in pin length or insulator height.
