Key Parameters

Substitute Part Grouping Explanation

Substitution for the M2011SS1W02 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Electrical Ratings: Current (6A AC / 4A DC) and voltage (125V AC / 30V DC) ratings must be met or exceeded
• Mechanical Interface: Panel cutout diameter (6.50mm), bushing thread (1/4-40), and actuator dimensions must be identical
• Termination Compatibility: The termination style determines physical and electrical connection feasibility

The M2011SS1W01 qualifies as a direct substitute based on identical electrical ratings, mechanical dimensions, and circuit configuration. The primary distinction is the termination style: M2011SS1W02 uses Quick Connect terminals, while M2011SS1W01 uses Solder Lug terminals. This difference requires evaluation of the application's connection method.

Parameter Comparison

Engineering Selection Recommendations

Both the M2011SS1W02 and M2011SS1W01 are classified as obsolete products. Selection between these parts depends on the termination interface available in the target application:

• M2011SS1W02: Use when the circuit board or wiring harness accommodates quick connect 0.062" (1.5mm) terminals
• M2011SS1W01: Use when solder lug termination is required for direct PCB soldering or wire attachment

Both parts maintain identical electrical performance, mechanical fit, and compliance certifications (ROHS3 Compliant, REACH Unaffected). The choice is determined solely by the connection method specified in the original equipment design.

Frequently Asked Questions (FAQ)

Q: Can M2011SS1W01 be used as a direct replacement for M2011SS1W02?

A: Electrical and mechanical compatibility is confirmed. The termination style differs: M2011SS1W02 features quick connect terminals while M2011SS1W01 uses solder lugs. Substitution is feasible only if the application's connection interface can accommodate solder lug termination.

Q: Are the panel cutout dimensions identical between these parts?

A: Yes. Both parts require a circular 6.50mm diameter panel cutout with 1/4-40 bushing thread. Physical installation dimensions are identical.

Q: Do both parts meet the same electrical specifications?

A: Yes. Both parts are rated for 6A at 125V AC and 4A at 30V DC, with identical operating temperature ranges (-30°C to 85°C) and electrical life (25,000 cycles).

Q: What is the significance of the obsolete product status?

A: Both parts are classified as obsolete, indicating they are no longer in active production. Availability is limited to existing inventory. Long-term supply cannot be guaranteed.

Q: Are there compliance differences between M2011SS1W02 and M2011SS1W01?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 ECCN classification.
