Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS1200G is based on electrical and mechanical parameter equivalence within the MSS series. The substitute part 1825257-2 maintains identical specifications across all critical switching parameters: SPDT circuit configuration, 0.4VA current rating at 20V (both AC and DC), shorting contact timing with On-On function, and mechanical characteristics including 5.00mm actuator length, 2.00mm switch travel, and 600gf operating force. Both parts utilize copper alloy contacts with gold finish, epoxy sealed terminals, and through-hole PC pin termination. The operating temperature range, mechanical life, and electrical life specifications are identical. The primary distinction between these parts is product status: MSS1200G is obsolete while 1825257-2 is active, and packaging configuration differs (standard versus bulk).

Parameter Comparison

Engineering Selection Recommendations

The MSS1200G is classified as obsolete, necessitating transition to an active equivalent for new procurement. Part number 1825257-2 is the direct substitute, maintaining complete electrical and mechanical equivalence across all specified parameters. The 1825257-2 is actively manufactured and carries ROHS3 compliance certification, providing assurance of regulatory alignment with current environmental standards. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications, ensuring consistent export and tariff treatment. The substitute part is available in bulk packaging with significantly higher inventory levels (2064 pieces versus 699 pieces), supporting production continuity and supply chain reliability. Selection of 1825257-2 eliminates obsolescence risk while maintaining full functional and physical compatibility with existing designs utilizing the MSS1200G.
