Omron Z-15EW-B Equivalent & Substitute Parts

Part Overview

The Omron Z-15EW-B is an active-status snap action switch with SPDT circuit configuration, rated for 15A at 125V AC and 30V DC. This chassis-mount switch features a straight lever actuator with screw terminal connections and is designed for applications requiring reliable electromechanical switching. The part is RoHS compliant and maintains unlimited moisture sensitivity rating (MSL 1). Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple suppliers, and maintain operational continuity when primary stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Z-15EW-B is determined by the following critical parameters:

• Circuit Configuration: Must be SPDT to maintain identical switching logic
• Switch Function: Must be On-Mom for consistent operational behavior
• Actuator Type: Must be Lever, Straight to ensure mechanical compatibility with existing mounting and actuation requirements
• Mounting Type: Must be Chassis Mount for direct mechanical and electrical integration
• Termination Style: Must be Screw Terminal for connection compatibility
• Current Rating (AC): Must support minimum 15A at 125V AC
• Voltage Rating (AC): Must support minimum 125V AC
• RoHS Compliance: Must maintain RoHS compliance status for regulatory alignment

The Honeywell BZ-2RW84-A2 meets all critical substitution criteria. While this part exhibits different DC current ratings (500mA versus the original 30V specification) and expanded operating temperature range (-55°C to 85°C versus -25°C to 80°C), it maintains full compatibility across all primary electrical and mechanical parameters required for direct substitution in AC-dominant applications.

Engineering Selection Recommendations

Both the Omron Z-15EW-B and Honeywell BZ-2RW84-A2 maintain active product status and full RoHS compliance, ensuring regulatory alignment and long-term supply availability. Selection between these parts should be based on application-specific requirements:

The Omron Z-15EW-B is the primary choice when the original design specifications and established supply chain are preferred. The Honeywell BZ-2RW84-A2 serves as a qualified substitute when supply constraints affect the primary part, offering enhanced mechanical durability (20,000,000 cycles versus 300,000 cycles) and extended operating temperature range (-55°C to 85°C versus -25°C to 80°C). Both parts are suitable for AC-dominant switching applications at 15A, 125V. Applications requiring DC switching should evaluate the reduced DC current rating of the Honeywell part (500mA) against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the Honeywell BZ-2RW84-A2 directly replace the Omron Z-15EW-B in all applications?

A: Direct replacement is suitable for AC-dominant switching applications. Both parts share identical SPDT circuit configuration, On-Mom function, 15A AC rating at 125V, straight lever actuator, chassis mount, and screw terminal termination. Applications requiring DC switching should evaluate whether the Honeywell part's 500mA DC rating meets circuit requirements, as the original Omron part supports 30V DC.

Q: What are the key mechanical differences between these parts?

A: The Honeywell BZ-2RW84-A2 provides significantly higher mechanical life (20,000,000 cycles versus 300,000 cycles) and operates across a wider temperature range (-55°C to 85°C versus -25°C to 80°C). Both parts maintain identical actuator type, mounting configuration, and termination style.

Q: Are both parts RoHS compliant?

A: Yes, both the Omron Z-15EW-B and Honeywell BZ-2RW84-A2 are RoHS compliant, ensuring regulatory alignment for applications subject to RoHS requirements.

Q: What packaging considerations apply to these parts?

A: The Omron Z-15EW-B is supplied in standard packaging, while the Honeywell BZ-2RW84-A2 is available in bulk packaging. Verify packaging requirements with your procurement process before ordering.

Q: How do the electrical life specifications compare?

A: The Omron Z-15EW-B specifies 100,000 electrical cycles. The Honeywell BZ-2RW84-A2 does not provide an electrical life specification in the available data. Both parts specify mechanical life ratings, with the Honeywell part offering substantially higher mechanical durability.
