Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-1825042-1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (4PDT), switch function (On-On), current ratings (6A AC / 4A DC), and voltage ratings (125V AC / 28V DC) must be identical.

Mechanical Parameters: Mounting type (Panel Mount, Rear), termination style (Solder Lug), actuator type (Round, Button), and panel cutout dimensions (11.80mm circular) must match exactly.

Environmental Parameters: Operating temperature range (-20°C to 80°C) and electrical life (50,000 cycles) must be maintained.

Series Alignment: The substitute part must belong to the same MPG series to ensure design compatibility and form-factor consistency.

The MPG406N meets all these criteria and is classified as active-status, making it a direct functional equivalent suitable for replacement in applications currently using the obsolete 1-1825042-1.

Parameter Comparison

Engineering Selection Recommendations

The MPG406N is the direct equivalent for the obsolete 1-1825042-1. Selection of the MPG406N is based on the following engineering factors:

Product Status: The MPG406N carries active-status classification, ensuring ongoing manufacturer support, availability, and supply chain continuity. The 1-1825042-1 is obsolete and no longer manufactured.

Regulatory Compliance: The MPG406N is ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements for new designs and production. This compliance status supports long-term design viability and market acceptance.

Functional Equivalence: All electrical, mechanical, and environmental parameters are identical between the two parts. No design modifications are required for direct substitution.

Series Continuity: Both parts belong to the TE Connectivity ALCOSWITCH MPG series, ensuring consistent performance characteristics and interchangeability within existing panel mount applications.

For applications currently using the 1-1825042-1, transition to the MPG406N provides equivalent functionality with the advantage of active product status and modern regulatory compliance.
