Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-RW922-A2 is determined by the following mandatory parameters:

Primary Substitution Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• AC voltage rating must be 125V
• Current rating must equal or exceed 10A AC

Secondary Compatibility Factors:

• Operating temperature range must encompass or match the application environment
• Mechanical life rating must support the intended duty cycle
• RoHS compliance status must align with regulatory requirements

The identified substitute parts meet these criteria while maintaining functional equivalence for direct component replacement in circuits designed for the BZ-RW922-A2.

Parameter Comparison

Engineering Selection Recommendations

Z-15GDA55-B5V (Omron Automation and Safety): This substitute provides 15A AC current capacity, exceeding the 10A requirement of the BZ-RW922-A2. Both parts share identical SPDT circuit topology, On-Momentary function, chassis mount configuration, and screw terminal termination. The Z-15GDA55-B5V maintains 20,000,000 mechanical life cycles matching the main part. ROHS3 compliance satisfies regulatory requirements. The operating temperature range of -15°C to 80°C is suitable for applications within this envelope. The round pin plunger actuator differs from the lever roller design, requiring mechanical interface verification. IP62 ingress protection provides enhanced environmental sealing compared to the unspecified rating of the main part.

A-20GV-B (Omron Automation and Safety): This substitute provides 20A AC current capacity, significantly exceeding the 10A requirement. SPDT circuit topology, On-Momentary function, chassis mount configuration, and screw terminal termination are identical to the main part. ROHS3 compliance is satisfied. The operating temperature range of -25°C to 80°C covers standard industrial environments. Mechanical life is rated at 1,000,000 cycles, substantially lower than the 20,000,000 cycles of the BZ-RW922-A2, limiting suitability for high-cycle applications. The lever straight actuator differs from the lever roller design. IP00 ingress protection indicates no environmental sealing.

Frequently Asked Questions (FAQ)

Q: Can the Z-15GDA55-B5V directly replace the BZ-RW922-A2 in all applications?

A: The Z-15GDA55-B5V meets all primary electrical and mechanical substitution criteria: SPDT circuit, On-Momentary function, 125V AC rating with 15A capacity, chassis mount, and screw terminal termination. However, the actuator type differs (round pin plunger versus lever roller), requiring verification that the mechanical interface and actuation geometry are compatible with the target application's mechanical design.

Q: What is the primary limitation of the A-20GV-B as a substitute?

A: The A-20GV-B is limited by its mechanical life rating of 1,000,000 cycles, compared to 20,000,000 cycles for the BZ-RW922-A2. Applications requiring extended cycle life or continuous duty operation should not use this substitute. The lever straight actuator also differs mechanically from the lever roller design.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the Z-15GDA55-B5V and A-20GV-B carry ROHS3 compliance certification, meeting current regulatory requirements. The main part BZ-RW922-A2 is RoHS Compliant. All three parts satisfy RoHS directives.

Q: What is the significance of the operating temperature range differences?

A: The BZ-RW922-A2 operates from -55°C to 85°C, providing the widest temperature envelope. The Z-15GDA55-B5V operates from -15°C to 80°C, and the A-20GV-B from -25°C to 80°C. Substitutes are suitable only for applications operating within their specified temperature ranges. Applications requiring operation below -15°C should not use either substitute.

Q: How do the ingress protection ratings affect substitution decisions?

A: The BZ-RW922-A2 has no specified ingress protection rating. The Z-15GDA55-B5V provides IP62 protection (dust-tight and water-jet resistant), offering enhanced environmental sealing. The A-20GV-B provides IP00 (no protection). Selection depends on the target application's environmental exposure requirements.

Q: What packaging format is available for these parts?

A: All three parts are supplied in Bulk packaging. The BZ-RW922-A2 has 744 units in stock, the Z-15GDA55-B5V has 1,057 units in stock, and the A-20GV-B has 1,079 units in stock.
