BZ-2RW80225-A2 Equivalent & Substitute Parts

Part Overview

The BZ-2RW80225-A2 is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis-mounted switch is rated for 15A AC at 125V with a lever straight actuator and screw terminal connections. The product is classified as obsolete, necessitating identification of equivalent alternatives for ongoing applications requiring SPDT snap action switching functionality at comparable electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZ-2RW80225-A2 is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-Mom), voltage rating (125V AC minimum), current rating capability, mounting type (chassis mount), and termination style (screw terminal). The substitute parts listed meet these core electrical and mechanical requirements with variations in specific performance characteristics.

The substitute parts are grouped as follows:

Group 1 - Higher Current Rating: A-20GV22-B7-K (Omron) provides 20A AC capability, exceeding the original 15A rating, with roller lever actuator and active product status.

Group 2 - Matched Current Rating, Panel Mount Alternative: GPTCNC11 (ZF Electronics) maintains 15A AC rating with identical voltage specification but differs in mounting type (panel mount versus chassis mount) and actuator type (round pin plunger).

Group 3 - Lower Current Ratings: TZ-1G (Omron) and Z-01HD55-B (Omron) provide reduced current ratings (1A and 100mA respectively) suitable only for applications with lower current requirements than the original specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - A-20GV22-B7-K (Omron Automation and Safety): This part is the most suitable direct replacement for applications requiring equivalent or higher current capacity. It maintains 125V AC voltage rating, SPDT circuit configuration, On-Mom function, chassis mount configuration, and screw terminal termination. The 20A AC rating exceeds the original 15A specification, providing design margin. Active product status ensures ongoing availability and supply chain continuity. RoHS compliance is maintained. The roller lever actuator differs from the original straight lever but provides equivalent functional performance. Operating temperature range (-25°C to 80°C) is narrower than the original but covers standard industrial applications.

Secondary Substitute - GPTCNC11 (ZF Electronics): This part matches the original 15A AC current rating and 125V voltage specification with identical mechanical life rating (20,000,000 cycles). However, it differs in mounting type (panel mount versus chassis mount) and actuator type (round pin plunger versus lever straight). This substitute is applicable only when panel mount configuration is acceptable. ROHS3 compliance is maintained. Operating temperature range (0°C to 55°C) is more restrictive than the original.

Lower Current Alternatives - TZ-1G and Z-01HD55-B: These parts are suitable only for applications with significantly reduced current requirements (1A and 100mA respectively). TZ-1G offers extended operating temperature range (-65°C to 400°C) and active product status. Z-01HD55-B provides IP62 ingress protection and 500,000 cycle electrical life rating. Both maintain SPDT configuration and 125V AC voltage rating but are not direct replacements for 15A applications.

Frequently Asked Questions (FAQ)

Q: Can A-20GV22-B7-K directly replace BZ-2RW80225-A2 in existing designs?

A: Yes, for applications requiring 15A or less AC current at 125V. The A-20GV22-B7-K maintains chassis mount configuration, screw terminal termination, SPDT circuit, and On-Mom function. The 20A AC rating provides design margin above the original 15A specification. Verify that the operating temperature range (-25°C to 80°C) is acceptable for your application, as it is narrower than the original (-55°C to 85°C).

Q: What is the key difference between A-20GV22-B7-K and GPTCNC11?

A: The primary differences are mounting type and current rating. A-20GV22-B7-K is chassis mount with 20A AC rating, while GPTCNC11 is panel mount with 15A AC rating. Select based on your mechanical mounting requirements and current capacity needs.

Q: Why are TZ-1G and Z-01HD55-B listed as substitutes if they have lower current ratings?

A: These parts are listed as substitutes for applications where the original 15A current requirement does not apply. TZ-1G is suitable for 1A applications, and Z-01HD55-B for 100mA applications. Both maintain SPDT configuration and 125V AC voltage rating. Do not use these parts in applications requiring the original 15A capacity.

Q: Are all substitute parts RoHS compliant?

A: Yes. BZ-2RW80225-A2 is RoHS Compliant. A-20GV22-B7-K is RoHS Compliant. GPTCNC11, TZ-1G, and Z-01HD55-B are ROHS3 Compliant. All meet current RoHS requirements.

Q: What packaging options are available for substitute parts?

A: A-20GV22-B7-K is supplied in Tray packaging. GPTCNC11 is supplied in Bulk packaging. TZ-1G is supplied in Tray packaging. Z-01HD55-B is supplied in Bulk packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: Does the actuator type difference affect functional performance?

A: Actuator type differences (lever straight versus lever roller versus round pin plunger) affect mechanical interface and operating force characteristics but do not affect electrical switching performance when circuit configuration, voltage, and current ratings are equivalent. Verify mechanical fit within your application enclosure.

Q: What is the mechanical life comparison between substitute parts?

A: BZ-2RW80225-A2 and GPTCNC11 both specify 20,000,000 cycles. A-20GV22-B7-K specifies 1,000,000 cycles. TZ-1G specifies 100,000 cycles. Z-01HD55-B specifies 20,000,000 cycles. Select based on your application duty cycle requirements.
