Substitute Part Grouping Explanation

Substitution eligibility for the A3SA-90C1-05SW is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

• Circuit configuration (DPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (3A AC / 2A DC; 125V AC / 30V DC)
• Mounting interface (Panel Mount, Snap-In with 16.20mm square cutout)
• Actuator geometry and color (Square button, White)
• Illumination characteristics (LED, White, 5 VDC)
• Termination method (Quick Connect - 0.110" / 2.8mm)
• Environmental operating range (-10°C to 50°C)
• Mechanical and electrical life ratings (1,000,000 and 100,000 cycles respectively)

Parameter Comparison

Engineering Selection Recommendations

The A3SA-90C1-05EW is the direct equivalent substitute for the obsolete A3SA-90C1-05SW. Both components are manufactured by Omron Automation and Safety within the A3S series and maintain identical electrical, mechanical, and environmental specifications. The primary distinction is product status: the A3SA-90C1-05EW is active and currently available, while the A3SA-90C1-05SW is obsolete.

For new designs and replacement applications, the A3SA-90C1-05EW provides full functional and physical compatibility with existing installations designed around the A3SA-90C1-05SW. No circuit modifications, panel cutout adjustments, or termination changes are required.

Frequently Asked Questions (FAQ)

Q: Can the A3SA-90C1-05EW be used as a direct replacement for the A3SA-90C1-05SW?

A: Yes. Both components share identical electrical ratings (3A AC / 2A DC; 125V AC / 30V DC), circuit configuration (DPDT), mechanical interface (16.20mm square panel cutout, snap-in mounting), and termination method (Quick Connect 0.110" / 2.8mm). No modifications to existing installations are necessary.

Q: What is the difference between the A3SA-90C1-05SW and A3SA-90C1-05EW?

A: The components are electrically and mechanically identical. The A3SA-90C1-05EW is the active production equivalent of the obsolete A3SA-90C1-05SW, ensuring continued availability and supply chain support.

Q: Are there any panel cutout or mounting considerations when substituting these parts?

A: No. Both parts require an identical square panel cutout of 16.20mm x 16.20mm and use the same snap-in mounting mechanism. Existing panel installations designed for the A3SA-90C1-05SW accommodate the A3SA-90C1-05EW without modification.

Q: Do the illumination specifications match between these two parts?

A: Yes. Both components feature white LED illumination with a nominal voltage of 5 VDC, ensuring identical visual operation and control circuit compatibility.

Q: What is the mechanical and electrical life expectancy for the substitute part?

A: The A3SA-90C1-05EW maintains the same life ratings as the original: 1,000,000 mechanical cycles and 100,000 electrical cycles, supporting equivalent operational longevity.
