Key Parameters

Substitute Part Grouping Explanation

Substitution of the MHS222 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

Electrical Parameters: Circuit configuration (DPDT), current rating (300mA AC), voltage rating (125V AC), and contact timing (Shorting MBB) must be identical.

Mechanical Parameters: Mounting type (Through Hole), termination style (PC Pin), actuator type (Standard), actuator length (4.50mm), switch travel (4.00mm), and operating force (600gf) must match exactly.

Material and Environmental Parameters: Contact material (Copper Alloy), contact finish (Silver), actuator material (POM), operating temperature range (-20°C to 85°C), and feature set (Epoxy Sealed Terminals) must be preserved.

Life Ratings: Both mechanical life (15,000 cycles) and electrical life (15,000 cycles) must be maintained.

Parts meeting all these criteria are classified as direct electrical and mechanical equivalents suitable for one-to-one replacement.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH part number 1825289-1 is a direct equivalent substitute for the obsolete MHS222. All electrical parameters, mechanical dimensions, material specifications, and performance ratings are identical between the two parts.

The primary distinction is product status: the MHS222 is classified as obsolete, while 1825289-1 is active. This status difference makes 1825289-1 the appropriate selection for new designs, production builds, and component replenishment.

Both parts carry identical regulatory compliance certifications: REACH Unaffected status and EAR99 ECCN classification. The 1825289-1 additionally carries RoHS3 Compliance certification, providing enhanced environmental compliance for applications subject to RoHS requirements.

From an inventory perspective, 1825289-1 is available in significantly higher quantities (5235 pieces) compared to the MHS222 (1124 pieces), supporting sustained production requirements.
