BZ-2RW80282-A2 Equivalent & Substitute Parts Reference

Part Overview

The BZ-2RW80282-A2 is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions. This SPDT (Single Pole Double Throw) switch is rated for 5A at 125V AC and 500mA at 125V DC, featuring a lever actuator with straight configuration and chassis mount termination. The product is Active status and RoHS Compliant. Substitute parts may be required due to inventory constraints, application-specific performance requirements, or end-of-life considerations for the primary component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-2RW80282-A2 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Voltage rating (AC) must support 125V minimum
• Current rating must support the application load requirements

Secondary Consideration Parameters:

• Operating temperature range compatibility
• Mechanical life cycle requirements
• RoHS and regulatory compliance status
• Actuator type (lever vs. plunger configurations acceptable if primary criteria met)

The substitute parts TZ-1G and Z-01HD55-B meet the primary circuit and mounting requirements but differ in current ratings and operating characteristics. Selection depends on the specific current and temperature demands of the target application.

Parameter Comparison

Engineering Selection Recommendations

BZ-2RW80282-A2 Primary Application: Select the BZ-2RW80282-A2 for applications requiring 5A AC current capacity at 125V with extended temperature operation (-55°C to 85°C). This part maintains Active product status and RoHS Compliance, suitable for standard industrial switching applications.

TZ-1G Substitution Conditions: The TZ-1G is suitable only for applications with reduced current requirements (1A AC/DC maximum). This part supports extended temperature operation (-65°C to 400°C) but exhibits significantly lower mechanical life (100,000 cycles versus 20,000,000 cycles). Use TZ-1G only when current demand does not exceed 1A and mechanical cycle life is not a limiting factor. ROHS3 Compliance status is maintained.

Z-01HD55-B Substitution Conditions: The Z-01HD55-B is suitable only for low-current applications (100mA AC/DC maximum). This part matches the mechanical life specification (20,000,000 cycles) and maintains RoHS Compliance. Operating temperature range is restricted (-15°C to 80°C). DC voltage rating is limited to 30V. Use Z-01HD55-B only when current demand does not exceed 100mA and operating temperature remains within -15°C to 80°C.

Compliance Status: All three parts maintain MSL 1 (Unlimited) moisture sensitivity rating and EAR99 ECCN classification. All are RoHS compliant variants suitable for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can TZ-1G replace BZ-2RW80282-A2 in a 5A application?

A: No. The TZ-1G current rating is 1A AC/DC maximum, insufficient for 5A applications. Exceeding rated current will cause component failure and circuit malfunction.

Q: What is the primary difference between Z-01HD55-B and BZ-2RW80282-A2?

A: The Z-01HD55-B is rated for 100mA maximum current, compared to 5A for the BZ-2RW80282-A2. Additionally, Z-01HD55-B DC voltage rating is 30V versus 125V for the main part. Z-01HD55-B is suitable only for low-current signal switching applications.

Q: Are all three parts RoHS compliant?

A: Yes. BZ-2RW80282-A2 and Z-01HD55-B are RoHS Compliant. TZ-1G is ROHS3 Compliant. All meet RoHS regulatory requirements.

Q: What is the mechanical life difference between these parts?

A: BZ-2RW80282-A2 and Z-01HD55-B both support 20,000,000 mechanical cycles. TZ-1G supports only 100,000 cycles. For high-cycle applications, avoid TZ-1G.

Q: Can these parts be used interchangeably based on packaging?

A: No. Packaging format (Bulk versus Tray) does not determine functional compatibility. Electrical and mechanical parameters determine substitution eligibility. BZ-2RW80282-A2 is Bulk packaged; TZ-1G is Tray packaged; Z-01HD55-B is Bulk packaged.

Q: What temperature range is common to all three parts?

A: The overlapping temperature range is -15°C to 80°C, limited by Z-01HD55-B specifications. BZ-2RW80282-A2 extends to -55°C and 85°C; TZ-1G extends to -65°C and 400°C.

Q: Is DC voltage rating a critical substitution parameter?

A: Yes. BZ-2RW80282-A2 supports 125V DC. Both TZ-1G and Z-01HD55-B support only 30V DC. For 125V DC applications, only BZ-2RW80282-A2 is suitable.
