Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-2RW822-A2 is determined by the following critical parameters:

Primary Substitution Criteria:

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

Substitute parts Z-15G-B and Z-15GD-B meet all primary substitution criteria. Both are Omron SPDT switches with On-Mom function, 15A AC rating at 125V, chassis mount configuration, and screw terminals. These parts are functionally equivalent for applications requiring the specified electrical and mechanical parameters.

Substitute part A-20G-B exceeds the current rating requirement at 20A AC and meets all other primary criteria. This part is suitable for applications where higher current capacity is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Z-15G-B and Z-15GD-B are direct functional equivalents to the BZ-2RW822-A2. Both parts are ROHS3 compliant and maintain the 20,000,000 cycle mechanical life specification. Selection between Z-15G-B and Z-15GD-B depends on operating position requirements: Z-15G-B operates at 0.625" (15.9mm) while Z-15GD-B operates at 0.846" (21.5mm). Both are available in tray packaging.

A-20G-B is suitable for applications where higher AC current capacity (20A) is required. This part is ROHS3 compliant but has reduced mechanical life (1,000,000 cycles) compared to the primary part. A-20G-B is available in bulk packaging.

All substitute parts maintain SPDT circuit configuration, On-Mom function, 125V AC rating, chassis mount configuration, and screw terminal termination. Compliance certifications (RoHS, REACH, ECCN) are provided for all parts.

Frequently Asked Questions (FAQ)

Q: Can Z-15G-B or Z-15GD-B directly replace BZ-2RW822-A2 in existing applications?

A: Yes. Both Z-15G-B and Z-15GD-B meet the electrical specifications (SPDT, On-Mom, 15A AC, 125V) and mechanical mounting requirements (chassis mount, screw terminal) of the BZ-2RW822-A2. Verify operating position compatibility with your application before substitution.

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

A: Both parts are functionally equivalent SPDT switches with identical electrical ratings and mechanical life. The primary difference is operating position: Z-15G-B operates at 0.625" (15.9mm) while Z-15GD-B operates at 0.846" (21.5mm). Select based on your application's physical space and actuation requirements.

Q: Is A-20G-B a suitable substitute?

A: A-20G-B meets the core electrical and mechanical requirements (SPDT, On-Mom, 125V AC, chassis mount, screw terminal). The 20A AC rating exceeds the 15A requirement. However, A-20G-B has reduced mechanical life (1,000,000 cycles versus 20,000,000 cycles) and a narrower operating temperature range (-25°C to 80°C versus -55°C to 85°C). Use A-20G-B only when higher current capacity is required and reduced mechanical life is acceptable.

Q: What packaging options are available?

A: BZ-2RW822-A2 is supplied in bulk packaging. Z-15G-B and Z-15GD-B are supplied in tray packaging. A-20G-B is supplied in bulk packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. BZ-2RW822-A2 is RoHS Compliant. Z-15G-B, Z-15GD-B, and A-20G-B are all ROHS3 Compliant. All parts meet RoHS requirements for restricted substance elimination.
