MHS133RA Equivalent & Substitute Parts

Part Overview

The MHS133RA is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole triple-throw (SP3T) switch with a 300mA AC current rating at 125V. This through-hole, right-angle mounted component features an epoxy-sealed terminal design with a polyoxymethylene actuator and silver-finished copper alloy contacts. The MHS133RA is classified as obsolete, making identification of functionally equivalent active alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MHS133RA is based on electrical and mechanical parameter equivalence within the MHS series family. The substitute part 1825256-3 maintains identical specifications across all critical functional parameters: SP3T circuit configuration, 300mA AC current capacity, 125V AC voltage rating, shorting contact timing with On-On-On switching function, through-hole right-angle mounting, PC pin termination, 4.50mm actuator length, 2.00mm switch travel, 600gf operating force, copper alloy contacts with silver finish, and -20°C to 85°C operating temperature range. Both components share identical mechanical life (15,000 cycles) and electrical life (15,000 cycles) ratings.

The key parameters determining substitution eligibility are:

• Circuit configuration (SP3T)
• Current and voltage ratings (300mA AC / 125V AC)
• Contact timing and switch function (Shorting MBB / On-On-On)
• Mounting and termination specifications (Through Hole Right Angle / PC Pin)
• Physical dimensions (Actuator length, switch travel, operating force)
• Environmental operating range (-20°C to 85°C)

Parameter Comparison

Engineering Selection Recommendations

The part 1825256-3 is the direct functional equivalent for the obsolete MHS133RA. All electrical and mechanical parameters are identical, ensuring drop-in compatibility in applications requiring SP3T slide switches with 300mA AC / 125V AC ratings and through-hole right-angle mounting.

The primary advantage of 1825256-3 is its active product status, ensuring ongoing availability and supply chain continuity. Additionally, 1825256-3 carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and procurement cycles.

Both components share identical REACH and ECCN classifications, confirming equivalent regulatory standing. The epoxy-sealed terminal design, polyoxymethylene actuator material, and silver-finished copper alloy contacts are consistent across both parts, maintaining performance characteristics in the specified -20°C to 85°C operating temperature range.
