Omron ZAP-1B Pushbutton Switch - Equivalent & Substitute Parts

Part Overview

The Omron ZAP-1B is a panel-mount 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, necessitating identification of active equivalent parts to maintain system functionality and ensure continued availability for replacement and new installations. The ZAP-1B features a round black button actuator with screw terminal connections and IP65 ingress protection suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

The ZAP-1Y is a direct functional equivalent to the ZAP-1B within the Omron ZAP series. Substitution is valid based on the following matching parameters:

• Identical SPDT circuit configuration and On-Momentary switch function
• Matching electrical ratings: 15A AC at 125V and 6A DC at 30V
• Identical mechanical specifications: panel mount rear configuration with 30.50mm circular cutout
• Matching termination style: screw terminal connections
• Identical environmental protection: IP65 ingress protection rating
• Matching operating temperature range: -25°C to 80°C
• Equivalent mechanical and electrical life specifications: 1,000,000 and 500,000 cycles respectively

The primary distinction is actuator color (black for ZAP-1B versus yellow for ZAP-1Y) and product status (obsolete versus active). The ZAP-1Y maintains active production status and RoHS compliance, making it the recommended replacement for the discontinued ZAP-1B.

Parameter Comparison

Engineering Selection Recommendations

The ZAP-1Y is the appropriate substitute for the obsolete ZAP-1B based on product lifecycle and regulatory compliance. The ZAP-1Y maintains active manufacturing status, ensuring long-term availability and supply chain continuity. The ZAP-1Y carries RoHS compliance certification, meeting current environmental and regulatory requirements for industrial component procurement.

All electrical, mechanical, and environmental specifications are identical between the two parts. The actuator color difference (yellow versus black) is a visual distinction only and does not affect functional performance or electrical characteristics. Selection of the ZAP-1Y eliminates obsolescence risk while maintaining full functional compatibility with existing circuit designs and panel mounting configurations.

Frequently Asked Questions (FAQ)

Q: Can the ZAP-1Y directly replace the ZAP-1B in existing installations?

A: Yes. The ZAP-1Y is a direct functional replacement. All electrical ratings, circuit configuration, mounting dimensions, and termination methods are identical. The only difference is the actuator button color (yellow instead of black) and active product status.

Q: Are there any electrical performance differences between ZAP-1B and ZAP-1Y?

A: No. Both parts have identical current ratings (15A AC, 6A DC), voltage ratings (125V AC, 30V DC), mechanical life (1,000,000 cycles), and electrical life (500,000 cycles). They are functionally equivalent.

Q: Does the panel cutout size remain the same?

A: Yes. Both parts require a 30.50mm circular panel cutout. No mechanical modifications to the panel are necessary when substituting the ZAP-1Y for the ZAP-1B.

Q: What is the significance of the ZAP-1Y being RoHS compliant?

A: RoHS compliance indicates the ZAP-1Y meets current environmental regulations restricting hazardous substances. This is relevant for new designs and procurement in regulated industries. The ZAP-1B, being obsolete, does not carry this specification.

Q: Are screw terminal connections identical on both parts?

A: Yes. Both the ZAP-1B and ZAP-1Y use screw terminal connections with identical specifications, ensuring compatibility with existing wiring and terminal block configurations.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -25°C to 80°C, suitable for standard industrial control environments.
