ZAP-2B Equivalent & Substitute Parts

Part Overview

The ZAP-2B is an Omron Automation and Safety pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 15A AC at 125V and 6A DC at 30V. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, repair, and component sourcing. The ZAP-2B features panel mount rear installation with IP65 ingress protection and screw terminal connections, suitable for industrial control applications requiring reliable switching performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZAP-2B is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (15A AC @ 125V; 6A DC @ 30V)
• Mounting type (Panel Mount, Rear)
• Termination style (Screw Terminal)
• Ingress protection rating (IP65)
• Panel cutout dimensions (30.50mm circular)
• Operating temperature range (-25°C to 80°C)
• Mechanical and electrical life specifications

The ZAP-2A qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The only variance is actuator color (Blue vs. Black) and product status (Active vs. Obsolete), neither of which affects functional compatibility or electrical performance.

Parameter Comparison

Engineering Selection Recommendations

The ZAP-2A is the direct equivalent for ZAP-2B applications. Both components share identical electrical specifications, mechanical dimensions, and operational characteristics. The ZAP-2A holds Active product status, ensuring ongoing availability and supply chain continuity, whereas the ZAP-2B is classified as Obsolete. The ZAP-2A carries RoHS Compliance certification, meeting current environmental and regulatory standards for electronic components in industrial applications. Selection of the ZAP-2A eliminates obsolescence risk while maintaining full functional compatibility with existing circuit designs and panel mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the ZAP-2A directly replace the ZAP-2B in existing installations?

A: Yes. Both components are electrically and mechanically identical across all functional parameters. The ZAP-2A operates at identical current and voltage ratings, maintains the same SPDT circuit configuration, and fits the same 30.50mm panel cutout. No circuit modifications or mechanical adjustments are required.

Q: What is the significance of the actuator color difference?

A: Actuator color (Black on ZAP-2B, Blue on ZAP-2A) is a visual identification feature only and does not affect electrical performance, switching characteristics, or circuit compatibility.

Q: Why is the ZAP-2B classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The ZAP-2A, as an Active product from the same series, provides continued availability and supply security.

Q: Does RoHS Compliance on the ZAP-2A affect compatibility?

A: No. RoHS Compliance indicates the ZAP-2A meets environmental standards for hazardous substance restrictions. This certification does not alter electrical or mechanical compatibility with applications designed for the ZAP-2B.

Q: Are there packaging differences between these components?

A: The ZAP-2B is listed with "-" packaging designation, while the ZAP-2A is supplied in Bulk packaging. Both components are identical in form, fit, and function; packaging differences relate only to order quantity and delivery format.

Q: What termination method do both components use?

A: Both the ZAP-2B and ZAP-2A employ Screw Terminal connections, ensuring identical installation procedures and wiring compatibility.
