BZ-2RW82224-A2 Equivalent & Substitute Parts

Part Overview

The BZ-2RW82224-A2 is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis mount switch is rated for 15A AC at 125V and features a lever roller actuator with screw terminal connections. The product is Active status and RoHS Compliant, making it suitable for industrial control applications requiring reliable switching performance across extended temperature ranges from -55°C to 121°C.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-2RW82224-A2 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Current rating must support minimum 15A AC at 125V
• Actuator type must be Lever with Roller
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Mechanical life must meet or exceed 20,000,000 cycles

Secondary Compatibility Factors:

• Operating temperature range should encompass or overlap the -55°C to 121°C specification
• Differential travel and overtravel dimensions must be within 0.020" (0.5mm) and 0.094" (2.4mm) respectively
• RoHS compliance status must be current (RoHS Compliant or ROHS3 Compliant)

Parts are grouped into full equivalents and partial equivalents based on adherence to these parameters.

Parameter Comparison

Engineering Selection Recommendations

Full Equivalents (GPTCRM01 and GPTCRM11):

The GPTCRM01 and GPTCRM11 manufactured by ZF Electronics are functionally equivalent to the BZ-2RW82224-A2 for applications operating within the 0°C to 55°C temperature range. Both parts share identical SPDT circuit configuration, 15A AC current rating at 125V, lever roller actuator, chassis mount configuration, and screw terminal termination. Mechanical life specifications match at 20,000,000 cycles. Both are ROHS3 Compliant, meeting current environmental standards. Operating force differential (158gf versus 170gf) and operating position variance (1.172" versus 1.188") fall within acceptable mechanical tolerances for standard industrial switching applications.

Partial Equivalent (TZ-1GV22):

The TZ-1GV22 manufactured by Omron Automation and Safety is a partial equivalent suitable only for low-current applications. This part does not meet the 15A AC current requirement, supporting only 1A AC/DC. The TZ-1GV22 is not recommended as a direct substitute for the BZ-2RW82224-A2 in applications requiring 15A switching capacity. However, the TZ-1GV22 offers extended temperature capability (-65°C to 400°C) and ROHS3 compliance for applications where current requirements are significantly lower than the primary specification.

Compliance and Status:

All identified substitute parts maintain Active product status and current RoHS compliance certifications. Selection should prioritize parts matching the specific current and voltage requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can GPTCRM01 or GPTCRM11 directly replace BZ-2RW82224-A2 in all applications?

A: GPTCRM01 and GPTCRM11 are direct replacements for applications operating within 0°C to 55°C. The BZ-2RW82224-A2 supports extended low-temperature operation to -55°C. If the application requires operation below 0°C, the Honeywell part is required. Both ZF Electronics parts maintain identical electrical ratings (15A AC at 125V) and mechanical specifications (20,000,000 cycle life, SPDT configuration, lever roller actuator, screw terminals).

Q: Why is TZ-1GV22 listed as a substitute if it only supports 1A current?

A: TZ-1GV22 is listed based on the provided substitute data but does not meet the primary current specification of 15A. This part is included for reference only and is not suitable for applications requiring the full 15A AC rating. Selection of TZ-1GV22 is appropriate only for independent low-current switching circuits.

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

A: Operating force varies from 158gf (ZF Electronics) to 170gf (Honeywell) to 240gf (Omron). Operating position ranges from 1.125" to 1.188". Differential travel is consistent at 0.020" to 0.025". These variations are within acceptable tolerances for standard industrial control applications but may affect actuator feel and response characteristics in sensitive applications.

Q: Are there packaging differences that affect component handling?

A: BZ-2RW82224-A2, GPTCRM01, and GPTCRM11 are supplied in Bulk packaging. TZ-1GV22 is supplied in Tray packaging. Bulk packaging is standard for industrial switches and does not affect electrical or mechanical performance. Packaging selection should align with assembly and inventory management procedures.

Q: What is the significance of RoHS Compliant versus ROHS3 Compliant status?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. RoHS Compliant indicates compliance with the original RoHS Directive. ROHS3 Compliant indicates compliance with the updated RoHS Directive 2011/65/EU. Both are current and acceptable for new designs. ROHS3 Compliant parts represent the current standard for environmental compliance.

Q: Can these parts be used interchangeably in existing designs?

A: GPTCRM01 and GPTCRM11 can be used interchangeably with BZ-2RW82224-A2 provided the application operates within 0°C to 55°C and does not require the extended low-temperature capability of the Honeywell part. Mechanical dimensions are sufficiently similar for standard chassis mount applications. Verification of mounting hole alignment and terminal spacing is recommended during design review.
