Equivalent & Substitute Parts for BZ-2AW822T

Part Overview

The BZ-2AW822T is an active-status snap action switch manufactured by Honeywell Sensing and Productivity Solutions. This SPDT (Single Pole Double Throw) switch is rated for 15A AC at 125V and features a lever actuator with straight configuration, designed for chassis mount applications with screw terminal termination. The switch operates across a temperature range of -55°C to 85°C with mechanical life rated at 20,000,000 cycles. RoHS compliance and MSL Level 1 classification ensure suitability for standard industrial and commercial applications.

Substitute parts are identified when equivalent electrical ratings, circuit configuration, mounting type, and termination style align with the main part specifications, enabling direct functional replacement in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZ-2AW822T are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Circuit configuration: SPDT
• AC current rating: 15A minimum
• AC voltage rating: 125V
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Switch function: On-Mom
• Product status: Active

The three identified substitutes (Z-15GD-B, Z-15GD55-B, Z-15GS-B) are manufactured by Omron Automation and Safety and satisfy all primary matching criteria. All substitutes maintain SPDT circuit topology, 15A AC rating at 125V, chassis mount configuration, and screw terminal termination. Variations exist in actuator type (round pin plunger versus lever straight), operating force characteristics, ingress protection rating, and operating temperature range, which are secondary considerations for substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

BZ-2AW822T Primary Application: The BZ-2AW822T is suitable for AC-dominant applications requiring 15A switching at 125V with extended low-temperature operation down to -55°C. The lever actuator design and higher DC voltage rating (125V) distinguish this part for specific mechanical actuation requirements.

Z-15GD-B Selection Criteria: The Z-15GD-B substitute is appropriate for applications where the operating temperature range of -25°C to 80°C is acceptable and where the round pin plunger actuator is compatible with mechanical design constraints. This variant offers standard ingress protection (IP00) and is suitable for general industrial switching applications.

Z-15GD55-B Selection Criteria: The Z-15GD55-B is specified for applications requiring enhanced ingress protection (IP62) and higher operating force (540gf). This variant is suitable for environments with moisture or dust exposure. The operating temperature range (-15°C to 80°C) is narrower than the main part, limiting use in extreme cold applications.

Z-15GS-B Selection Criteria: The Z-15GS-B provides operating position of 1.110" (28.2mm), which more closely approximates the BZ-2AW822T operating position of 1.188" (30.2mm) compared to other Omron substitutes. This variant is suitable for applications where mechanical stroke characteristics are critical to system design.

Compliance Considerations: All substitute parts maintain RoHS3 compliance and MSL Level 1 classification, ensuring compatibility with standard manufacturing and storage protocols. The BZ-2AW822T carries RoHS Compliant status, while all Omron substitutes carry ROHS3 Compliant status, both acceptable for equivalent environmental compliance.

DC Voltage Rating Limitation: Substitutes exhibit reduced DC voltage rating (30V) compared to the main part (125V). Applications requiring 125V DC switching must retain the BZ-2AW822T.

Frequently Asked Questions (FAQ)

Q: Can Z-15GD-B, Z-15GD55-B, or Z-15GS-B directly replace BZ-2AW822T in all applications?

A: Direct replacement is valid for AC-dominant applications at 15A and 125V with chassis mount screw terminal configuration. However, three factors require evaluation: (1) DC voltage applications exceeding 30V require the BZ-2AW822T due to its 125V DC rating; (2) operating temperatures below -25°C require the BZ-2AW822T due to its -55°C minimum rating; (3) mechanical actuator type differs (lever straight versus round pin plunger), requiring verification of mechanical interface compatibility.

Q: What is the significance of the operating force difference between BZ-2AW822T (240gf) and the Omron substitutes (250~350gf or 540gf)?

A: Operating force determines the mechanical effort required to actuate the switch. The BZ-2AW822T requires 240gf, while Z-15GD-B and Z-15GS-B require 250~350gf (slightly higher), and Z-15GD55-B requires 540gf (significantly higher). Applications with limited actuation force availability may not accommodate the higher-force Omron variants. Mechanical system design must account for this parameter.

Q: Why do the Omron substitutes have lower DC current ratings (6A) compared to the BZ-2AW822T (1A)?

A: The provided specifications indicate the BZ-2AW822T supports 1A DC while Omron substitutes support 6A DC. This represents a capability advantage for the Omron parts in DC applications within the 30V DC limit. However, the BZ-2AW822T maintains superior DC voltage rating (125V versus 30V).

Q: What is the difference between Z-15GD-B and Z-15GS-B?

A: Both parts are manufactured by Omron with identical electrical ratings, operating force range (250~350gf), and ingress protection (IP00). The primary difference is operating position: Z-15GD-B operates at 0.846" (21.5mm) while Z-15GS-B operates at 1.110" (28.2mm). Selection depends on mechanical stroke requirements of the application. Z-15GS-B more closely matches the BZ-2AW822T operating position of 1.188" (30.2mm).

Q: What does IP62 ingress protection on Z-15GD55-B indicate?

A: IP62 rating indicates protection against dust ingress and water spray from any direction. This variant is suitable for applications with moisture or dust exposure. Z-15GD-B and Z-15GS-B carry IP00 rating, indicating no special ingress protection. Selection of Z-15GD55-B is appropriate for harsh environmental conditions.

Q: Are packaging differences (Bulk for BZ-2AW822T versus Tray for Omron parts) significant for substitution?

A: Packaging differences affect supply chain logistics and storage but do not impact electrical or mechanical functionality. Bulk packaging typically indicates larger quantity availability, while tray packaging is standard for component distribution. Substitution is valid regardless of packaging format.

Q: What is the REACH status significance for Z-15GS-B?

A: Z-15GS-B carries REACH Affected status, indicating the part contains substances of concern under REACH regulations. Z-15GD-B and Z-15GD55-B carry REACH Unaffected status. Applications subject to REACH compliance requirements should prioritize Z-15GD-B or Z-15GD55-B over Z-15GS-B.
