Equivalent & Substitute Parts for BZ-7RW822-A2

Part Overview

The BZ-7RW822-A2 is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis mount switch is rated for 15A at 125V AC and 500mA at 125V DC, featuring a lever roller actuator with screw terminal connections. The product is classified as obsolete, making identification of equivalent and substitute parts essential for system maintenance and component replacement in existing installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-7RW822-A2 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Current rating must support minimum 15A AC at 125V AC
• Voltage ratings must support 125V AC operation
• DC current capability must be evaluated for specific application requirements

Mechanical Compatibility Requirements:

• Actuator type must be Lever, Roller
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Operating position, differential travel, and overtravel parameters must be within acceptable tolerance ranges for mechanical fit and function

Compliance Requirements:

• RoHS compliance status must be verified
• Moisture sensitivity level must be compatible with storage and handling conditions

The substitute parts GPTCRM01 and GPTCRM11 (both ZF Electronics) meet the core electrical and mechanical requirements with active product status. The TZ-1GV22 (Omron Automation and Safety) does not meet current rating requirements and is therefore not suitable as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Recommended Substitutes: GPTCRM01 and GPTCRM11

Both GPTCRM01 and GPTCRM11 manufactured by ZF Electronics are suitable substitutes for the obsolete BZ-7RW822-A2. These parts maintain active product status and provide equivalent electrical performance at 15A AC and 125V AC ratings. Both parts are ROHS3 compliant, exceeding the RoHS compliance requirement of the original part. The mechanical parameters are compatible with chassis mount applications using screw terminal connections.

The ZF Electronics substitutes feature identical release force (43gf) and overtravel (0.094") specifications. Operating force is reduced from 198gf to 158gf, and differential travel is reduced from 0.050" to 0.020", representing minor mechanical variations within acceptable substitution parameters for SPDT lever roller switches.

Operating temperature range for the ZF Electronics substitutes is 0°C to 55°C, which is narrower than the original BZ-7RW822-A2 range of -55°C to 85°C. Applications requiring operation below 0°C or above 55°C must evaluate this limitation against specific system requirements.

Not Recommended: TZ-1GV22

The TZ-1GV22 manufactured by Omron Automation and Safety does not qualify as a substitute. The current rating of 1A AC is insufficient for the 15A AC requirement of the original part. Although this part shares SPDT circuit configuration, lever roller actuator type, and chassis mount configuration, the electrical rating deficiency makes it unsuitable for direct replacement in applications designed for 15A operation.

Frequently Asked Questions (FAQ)

Q: Can GPTCRM01 and GPTCRM11 be used interchangeably with BZ-7RW822-A2?

A: Yes. Both ZF Electronics parts meet the electrical and mechanical requirements for substitution. GPTCRM01 and GPTCRM11 are functionally equivalent for applications requiring 15A AC at 125V AC with SPDT on-momentary operation and chassis mount configuration.

Q: What is the difference between GPTCRM01 and GPTCRM11?

A: The provided specifications indicate identical electrical and mechanical parameters for both parts. Both are manufactured by ZF Electronics, share the same base product number (GPTCRM), and are supplied in bulk packaging. Selection between these parts should be based on availability and packaging requirements.

Q: Why is TZ-1GV22 not suitable as a substitute?

A: The TZ-1GV22 is rated for 1A AC maximum current, while the BZ-7RW822-A2 requires 15A AC capability. Using an undersized current rating component creates risk of switch failure and potential safety hazards in the application circuit.

Q: Are there temperature limitations when substituting with ZF Electronics parts?

A: Yes. The GPTCRM01 and GPTCRM11 operate within 0°C to 55°C, compared to the original part's -55°C to 85°C range. Applications requiring operation outside the 0°C to 55°C window must verify compatibility with system thermal requirements before substitution.

Q: What packaging options are available for substitute parts?

A: GPTCRM01 and GPTCRM11 are supplied in bulk packaging. The original BZ-7RW822-A2 packaging format is not specified in the provided data. Verify packaging compatibility with receiving and handling procedures.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both GPTCRM01 and GPTCRM11 are ROHS3 compliant, meeting or exceeding the RoHS compliance requirement of the original part.

Q: What are the mechanical differences between the original and substitute parts?

A: Operating force is reduced from 198gf to 158gf, and differential travel is reduced from 0.050" to 0.020" in the ZF Electronics substitutes. Operating position changes from 1.188" to 1.172", and pretravel is specified as 0.106" for the substitutes. These variations are within acceptable mechanical tolerance ranges for SPDT lever roller switch applications.
