MSS42G Equivalent & Substitute Parts

Part Overview

The MSS42G is a slide switch manufactured by APEM Inc., configured as a 4PDT (four-pole double-throw) switch rated for 0.4VA at 20V AC/DC. This through-hole mounted component features gold-plated contacts, epoxy sealed terminals, and is designed for On-On switching applications. The MSS42G is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

• REACH unaffected status

The 1825264-2 maintains electrical and mechanical compatibility with the MSS42G while offering an active product status from an established manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The 1825264-2 from TE Connectivity ALCOSWITCH Switches is a direct functional equivalent to the obsolete MSS42G. Both components meet ROHS3 compliance requirements and maintain REACH unaffected status. The substitute part offers extended operating temperature range (-20°C to 85°C versus -10°C to 60°C) and increased electrical life rating (15,000 cycles versus 10,000 cycles), providing enhanced performance margins within the same electrical and mechanical envelope. The active product status of the 1825264-2 ensures long-term availability and supply chain continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the 1825264-2 be used as a direct replacement for the MSS42G in existing designs?

A: Yes. Both components share identical electrical ratings (0.4VA at 20V AC/DC), circuit configuration (4PDT), mounting type (through-hole PC pin), and physical dimensions (8.00mm actuator length, 2.00mm switch travel). The 1825264-2 maintains gold-plated contact finish and epoxy sealed terminal construction.

Q: What are the key differences between these two parts?

A: The primary differences are product status and performance ratings. The MSS42G is obsolete, while the 1825264-2 is active. The 1825264-2 offers a wider operating temperature range (-20°C to 85°C) and higher electrical life (15,000 cycles). The MSS42G operates from -10°C to 60°C with 10,000 cycle electrical life.

Q: Are both parts RoHS compliant?

A: Yes. Both the MSS42G and 1825264-2 are ROHS3 compliant and REACH unaffected.

Q: What is the contact timing specification for the 1825264-2?

A: The 1825264-2 features shorting contact timing (MBB - make-before-break).

Q: Are there packaging differences between these parts?

A: The MSS42G is supplied in standard packaging, while the 1825264-2 is supplied in bulk packaging. Both are through-hole mounted components with PC pin termination.
