Key Parameters

Substitute Part Grouping Explanation

Substitution of the M2011SS4W03 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Switch function (On-Off)
• Current and voltage ratings (6A AC / 4A DC; 125V AC / 30V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 10.50mm length)
• Termination style (PC Pin)
• Panel cutout geometry (Circular 6.50mm diameter)
• Bushing thread specification (M6 x 0.75)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (25,000 cycles)

The substitute part MN11SS4W03 maintains functional and mechanical equivalence across these parameters while offering active product status and current manufacturing availability.

Frequently Asked Questions (FAQ)

Q: What makes MN11SS4W03 a suitable substitute for M2011SS4W03?

A: MN11SS4W03 maintains identical electrical ratings (6A AC / 4A DC; 125V AC / 30V DC), circuit configuration (SPST), mechanical mounting specifications (panel mount with M6 x 0.75 bushing thread), and operating temperature range (-30°C to 85°C). Both components feature PC pin termination and equivalent panel cutout geometry.

Q: Does the packaging difference affect substitution compatibility?

A: Packaging format (bulk versus other configurations) does not affect electrical or mechanical compatibility. Packaging selection is determined by procurement and inventory management requirements rather than functional performance.

Q: Are there any compliance differences between the two parts?

A: Both M2011SS4W03 and MN11SS4W03 maintain ROHS3 compliance. No compliance barriers exist for substitution.

Q: What is the primary reason for substituting M2011SS4W03?

A: The M2011SS4W03 is classified as obsolete. MN11SS4W03 provides equivalent functionality with active product status and assured long-term availability from the manufacturer.
