Parameter Comparison

Engineering Selection Recommendations

The APEM Inc. 8446AB is a qualified substitute for the MB2085SS1W03. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The 8446AB offers the advantage of active product status with ongoing manufacturer support and availability, whereas the MB2085SS1W03 is obsolete. The 8446AB provides equivalent or superior electrical performance with a wider operating temperature range (-40°C to 85°C versus -30°C to 85°C) and higher DC current rating (4A versus 3A). All mechanical and electrical interfaces are identical, including panel cutout dimensions, termination style, and mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can the 8446AB directly replace the MB2085SS1W03 in existing applications?

A: Yes. Both components share identical circuit configuration (DPDT), switch function (On-On), AC ratings (6A at 125V), DC voltage rating (30V), mounting type (Panel Mount, Rear), actuator type (Plunger for Cap), termination style (PC Pin), and panel cutout dimensions (6.50mm Dia). The 8446AB meets or exceeds all electrical specifications of the MB2085SS1W03.

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

A: The primary differences are product status (8446AB is active; MB2085SS1W03 is obsolete), DC current rating (8446AB rated 4A; MB2085SS1W03 rated 3A), operating temperature range (8446AB: -40°C to 85°C; MB2085SS1W03: -30°C to 85°C), and electrical life (8446AB: 30,000 cycles; MB2085SS1W03: 25,000 cycles).

Q: Are there packaging differences between these components?

A: The MB2085SS1W03 is supplied in standard packaging, while the 8446AB is supplied in bulk packaging. Both use PC pin termination and epoxy sealed terminals.

Q: Do both parts meet current compliance standards?

A: Yes. Both the MB2085SS1W03 and 8446AB are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the panel cutout requirement for installation?

A: Both components require an identical circular panel cutout of 6.50mm diameter for rear panel mount installation.
