Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZ-2RW899-A2 is determined by compatibility across the following critical parameters:

Circuit and Function Compatibility: The substitute part must maintain SPDT circuit configuration and On-Mom switch function to ensure electrical behavior equivalence.

Voltage and Current Ratings: The substitute must support minimum 125V AC operation. AC current rating of the substitute must equal or exceed 15A at 125V. DC voltage and current ratings may differ from the original part.

Mechanical Interface: The substitute must feature chassis mount configuration with screw terminal connections and a straight lever actuator to ensure physical installation compatibility.

Environmental and Compliance Requirements: The substitute must maintain RoHS compliance and operate within acceptable temperature ranges for the intended application.

The A-20GV-B from Omron Automation and Safety meets these substitution criteria with the following considerations: it provides higher AC current capacity (20A), maintains SPDT configuration and On-Mom function, supports 125V AC operation, features identical mounting and termination styles, and maintains RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (BZ-2RW899-A2): Select this Honeywell part when the application requires the extended operating temperature range of -55°C to 85°C. This part is RoHS compliant and maintains active product status with established supply availability.

Substitute Part (A-20GV-B): The Omron A-20GV-B is suitable as a substitute when the application operates within the -25°C to 80°C temperature range. This part provides higher AC current capacity (20A versus 15A), which offers additional margin in applications with variable load conditions. Both parts maintain RoHS compliance and active product status. The A-20GV-B is ROHS3 compliant and REACH affected, indicating compliance with current regulatory standards.

Selection Criteria: Choose the BZ-2RW899-A2 for applications requiring extended low-temperature operation below -25°C. Choose the A-20GV-B when higher current capacity is beneficial and temperature requirements fall within -25°C to 80°C.

Frequently Asked Questions (FAQ)

Q: Can the A-20GV-B directly replace the BZ-2RW899-A2 in all applications?

A: The A-20GV-B is mechanically and electrically compatible for applications operating within -25°C to 80°C. Applications requiring operation below -25°C must use the BZ-2RW899-A2 due to its extended temperature range.

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

A: The primary differences are: (1) AC current rating (15A for BZ-2RW899-A2 versus 20A for A-20GV-B), (2) operating temperature range (-55°C to 85°C for BZ-2RW899-A2 versus -25°C to 80°C for A-20GV-B), and (3) DC voltage rating (125V for BZ-2RW899-A2 versus 30V for A-20GV-B).

Q: Are both parts RoHS compliant?

A: Yes. The BZ-2RW899-A2 is RoHS compliant. The A-20GV-B is ROHS3 compliant, which represents current regulatory compliance standards.

Q: Do these parts have identical mechanical interfaces?

A: Yes. Both parts feature chassis mount configuration, screw terminal connections, and straight lever actuators. Operating force and release force values are nearly identical (71gf/14gf for BZ-2RW899-A2 and 70gf/14gf for A-20GV-B).

Q: What is the significance of the higher current rating on the A-20GV-B?

A: The 20A AC rating on the A-20GV-B provides additional capacity margin compared to the 15A rating of the BZ-2RW899-A2. This allows the Omron part to handle applications with higher current demands or provides safety margin in circuits with variable loads.

Q: Are there packaging differences between these parts?

A: The BZ-2RW899-A2 is supplied in standard packaging. The A-20GV-B is supplied in bulk packaging. Verify packaging requirements for your procurement process.
