Substitute Part Grouping Explanation

Substitution of the obsolete MHS233 is based on electrical and mechanical parameter equivalence within the TE Connectivity ALCOSWITCH MHS product family. The substitute part must maintain identical specifications across the following critical parameters:

Circuit configuration (DP3T)
Current and voltage ratings (300mA AC / 125V AC)
Contact timing behavior (Shorting MBB)
Switch function (On-On-On)
Mounting and termination characteristics (Through Hole / PC Pin)
Physical dimensions (4.50mm actuator length)
Contact material and finish (Copper Alloy / Silver)
Operating temperature range (-20°C to 85°C)
Mechanical and electrical life ratings (15,000 Cycles)
Operating force (600gf)

The substitute part 1825289-8 satisfies all these parameters while offering active product status and improved compliance certifications.
