TE Connectivity ALCOSWITCH MHS122 Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH MHS122 is a slide switch with Single Pole Double Throw (SPDT) configuration rated for 300mA at 125V AC. This through-hole mounted component features a shorting contact timing design and is intended for On-On switch function applications. The MHS122 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity. The substitute part 1825255-1 provides functional equivalence while maintaining active product status within the TE Connectivity ALCOSWITCH portfolio.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MHS122 with the active part 1825255-1 is based on complete electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical selection criteria:

Electrical Parameters: Both parts maintain SPDT circuit configuration with 300mA AC current rating and 125V AC voltage rating. Contact timing (shorting/MBB) and switch function (On-On) are identical.

Mechanical Parameters: Actuator type, length (4.50mm), and material (POM) are identical. Switch travel distance (4.00mm) and operating force (600gf) match exactly.

Contact Specifications: Contact material (Copper Alloy) and finish (Silver) are identical across both parts.

Environmental Specifications: Operating temperature range (-20°C to 85°C), mechanical life (15,000 cycles), and electrical life (15,000 cycles) are identical.

Mounting and Termination: Both parts use through-hole mounting with PC pin termination style and feature epoxy sealed terminals.

The substitution is valid based on complete parameter alignment within the MHS series family.
