Omron Automation and Safety 44516-0620 Equivalent & Substitute Parts

Part Overview

The Omron Automation and Safety 44516-0620 is an electronic pushbutton switch designed for panel mount applications with a 2NC+1NO (2 normally closed + 1 normally open) contact configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy component sourcing is impractical.

Key Parameters

Substitute Part Grouping Explanation

The RAFI USA 1.15.105.021/0000 qualifies as a functional substitute based on the following critical parameters:

• Contact Configuration: Both parts feature 3PST (3 Pole Single Throw) switching with 2NC+1NO contact arrangement, ensuring electrical compatibility in circuits designed for the original component
• Mounting Type: Panel mount configuration with front access matches the original design intent
• Moisture Sensitivity Level: Both components are rated MSL 1 (Unlimited), indicating equivalent environmental tolerance
• Product Availability: The substitute part maintains active product status with current inventory, addressing the obsolescence limitation of the original component

Parameter Comparison

Engineering Selection Recommendations

The RAFI USA 1.15.105.021/0000 serves as the primary substitute for the obsolete Omron 44516-0620 based on matching contact configuration and mounting requirements. The substitute part carries active product status with ROHS3 compliance, providing regulatory alignment for new designs and system updates. The electrical specifications (2.5A at 250V AC / 240V DC) and environmental ratings (IP65, MSL 1) establish functional parity for standard industrial control applications. Physical integration requires verification of panel cutout compatibility with the specified 22.30mm circular aperture and termination method compatibility with existing circuit board or wiring infrastructure.

Frequently Asked Questions (FAQ)

Q: What makes the RAFI USA 1.15.105.021/0000 a suitable substitute for the Omron 44516-0620?

A: Both components share identical contact configuration (2NC+1NO), panel mount design, and MSL 1 environmental rating. The substitute maintains active product status, addressing the obsolescence of the original component.

Q: Are there mechanical compatibility considerations when substituting these parts?

A: Yes. The RAFI substitute specifies a 22.30mm circular panel cutout. Existing panel designs must accommodate this dimension. Termination methods differ (Solder and Quick Connect 0.110" for RAFI versus unspecified for Omron), requiring verification against existing circuit connections.

Q: What electrical parameters should be verified before substitution?

A: The RAFI substitute is rated 2.5A at 250V AC and 240V DC. Original circuit designs must operate within these electrical limits. If the original Omron component was specified for different voltage or current parameters, direct substitution may not be appropriate.

Q: Does the substitute part meet current regulatory requirements?

A: The RAFI USA 1.15.105.021/0000 is ROHS3 compliant and carries REACH Unaffected status, meeting current environmental and regulatory standards for industrial component applications.

Q: What is the significance of the IP65 rating on the substitute part?

A: IP65 classification indicates dust-tight and water-resistant construction. This environmental protection level should be verified against the original application requirements to ensure adequate protection in the intended operating environment.
