BZ-2R276-P5 Equivalent & Substitute Parts Reference

Part Overview

The BZ-2R276-P5 is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions. This component features a round pin plunger actuator, chassis mount configuration, and screw terminal termination, rated for 15A at 125V AC and 500mA at 125V DC. The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing applications and new designs. Substitute parts must maintain functional compatibility while meeting the electrical and mechanical requirements of the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-2R276-P5 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Actuator type must be round pin plunger
• Termination style must be screw terminal
• Voltage rating (AC) must be minimum 125V
• Operating temperature range must encompass the application requirements

Secondary Compatibility Considerations:

• Current rating must meet or exceed application demands
• Mounting type compatibility with chassis or panel mount configurations
• Mechanical life rating of minimum 20,000,000 cycles
• RoHS compliance status for regulatory alignment

The three identified substitute parts (GPTCNC11, TZ-1G, Z-01HD55-B) share the core SPDT circuit configuration and on-momentary function with round pin plunger actuation. However, each substitute exhibits distinct variations in current rating, mounting configuration, and operating specifications that determine suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

GPTCNC11 (ZF Electronics)

The GPTCNC11 provides the closest electrical equivalence to the BZ-2R276-P5, matching the 15A AC current rating and 125V AC voltage specification. Both components maintain 20,000,000 cycle mechanical life and SPDT on-momentary functionality. The primary distinction is mounting configuration: GPTCNC11 is panel mount versus the BZ-2R276-P5 chassis mount design. This substitute is suitable for applications where panel mounting is acceptable and operating temperature range of 0°C to +55°C satisfies application requirements. ROHS3 compliance status provides enhanced regulatory alignment for new designs.

TZ-1G (Omron Automation and Safety)

The TZ-1G maintains chassis mount compatibility and identical 0.625" operating position with the BZ-2R276-P5. However, current rating is reduced to 1A AC/DC, limiting applicability to low-current circuits. The TZ-1G offers extended operating temperature range (−65°C to +400°C) and ROHS3 compliance. Mechanical life is significantly reduced to 100,000 cycles. This substitute is applicable only for applications with current requirements below 1A and where extended temperature operation is required.

Z-01HD55-B (Omron Automation and Safety)

The Z-01HD55-B is rated for 100mA AC/DC current, substantially below the BZ-2R276-P5 specification of 15A AC. This component is suitable exclusively for low-signal switching applications. The Z-01HD55-B provides enhanced ingress protection (IP62) and extended electrical life (500,000 cycles). Mechanical life matches the original at 20,000,000 cycles. RoHS compliance and active product status support long-term availability. This substitute is applicable only for signal-level switching circuits.

Frequently Asked Questions (FAQ)

Q: Can GPTCNC11 directly replace BZ-2R276-P5 in existing designs?

A: GPTCNC11 provides electrical equivalence (15A AC, 125V AC, SPDT on-momentary) but differs in mounting type (panel mount versus chassis mount). Direct mechanical substitution requires enclosure modification. Electrical performance is equivalent within the specified operating temperature range of 0°C to +55°C.

Q: What is the primary limitation of TZ-1G as a substitute?

A: Current rating is reduced to 1A AC/DC compared to the BZ-2R276-P5 specification of 15A AC and 500mA DC. TZ-1G is suitable only for applications with current demands below 1A. Mechanical life is also reduced to 100,000 cycles versus 20,000,000 cycles.

Q: Is Z-01HD55-B suitable for high-current applications?

A: No. Z-01HD55-B is rated for 100mA AC/DC current, making it unsuitable for applications requiring 15A AC or 500mA DC. This component is designed for signal-level switching only.

Q: How do operating temperature ranges affect substitution decisions?

A: BZ-2R276-P5 operates from −55°C to +85°C. GPTCNC11 range is 0°C to +55°C, which is narrower. TZ-1G extends to −65°C to +400°C. Z-01HD55-B operates −15°C to +80°C. Substitute selection must ensure the operating temperature range encompasses all application conditions.

Q: What is the significance of mounting type differences?

A: BZ-2R276-P5 is chassis mount; GPTCNC11 is panel mount. Chassis mount components are installed through the equipment enclosure wall from inside. Panel mount components are installed from the front panel. Mechanical substitution requires compatible mounting infrastructure.

Q: Are all substitutes RoHS compliant?

A: Yes. BZ-2R276-P5 is RoHS Compliant; GPTCNC11, TZ-1G, and Z-01HD55-B are ROHS3 Compliant. All meet RoHS requirements for new designs and regulatory compliance.

Q: What packaging options are available?

A: BZ-2R276-P5 is supplied in standard packaging (not specified). GPTCNC11 is supplied in bulk packaging. TZ-1G is supplied in tray packaging. Z-01HD55-B is supplied in bulk packaging. Packaging selection affects inventory management and component handling procedures.

Q: Can multiple substitutes be used in the same application?

A: No. Each substitute has distinct electrical and mechanical specifications. A single substitute must be selected based on application current, voltage, temperature, and mounting requirements. Mixing substitutes within a single design is not recommended.
