Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZ-2RW84462-A2 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT (Single Pole Double Throw)
• Switch function: On-Momentary operation
• Voltage rating: Minimum 125V AC
• Termination style: Screw Terminal
• RoHS compliance status

Secondary Compatibility Considerations:

• Current rating capacity (minimum 15A AC for direct replacement)
• Mounting type (chassis mount preferred for form factor compatibility)
• Operating temperature range overlap
• Mechanical life rating

The substitute parts identified (GPTCNC11 and TZ-1G) share the core SPDT circuit configuration and on-momentary function. However, each presents distinct trade-offs in current rating, mounting type, and operating specifications that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

GPTCNC11 (ZF Electronics): This substitute maintains the 15A AC current rating and 125V AC voltage specification of the original BZ-2RW84462-A2. Both parts share identical mechanical life ratings of 20,000,000 cycles and ROHS3 compliance. The primary difference is mounting type: GPTCNC11 is panel mount versus the original chassis mount configuration. This substitute is suitable for applications where panel mounting is acceptable and the operating temperature range of 0°C to 55°C is sufficient. The part is currently active in production.

TZ-1G (Omron Automation and Safety): This substitute shares the chassis mount configuration and on-momentary function of the original part. However, the current rating is significantly reduced to 1A AC, making this option unsuitable for applications requiring the full 15A capacity of the BZ-2RW84462-A2. The TZ-1G is appropriate only for low-current applications. The part offers extended operating temperature range (-65°C to 400°C) and is currently active in production. Mechanical life is substantially lower at 100,000 cycles compared to 20,000,000 cycles for the original part.

Compliance Status: Both substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring regulatory compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can GPTCNC11 directly replace BZ-2RW84462-A2 in all applications?

A: GPTCNC11 maintains electrical compatibility (15A AC, 125V AC, SPDT, on-momentary function) and mechanical life specifications. However, the mounting type differs: GPTCNC11 is panel mount while BZ-2RW84462-A2 is chassis mount. Substitution is valid only if the application can accommodate panel mounting. Operating temperature range is narrower (0°C to 55°C versus -55°C to 85°C).

Q: Is TZ-1G suitable as a substitute for high-current applications?

A: No. TZ-1G is rated for 1A AC maximum, compared to the 15A AC rating of BZ-2RW84462-A2. This substitute is only appropriate for low-current control circuits. Additionally, mechanical life is 100,000 cycles versus 20,000,000 cycles for the original part.

Q: What are the key differences in actuator design between these parts?

A: BZ-2RW84462-A2 features a straight lever actuator, while both GPTCNC11 and TZ-1G use round pin plunger actuators. This affects the physical actuation method and may impact ergonomics and space constraints in the application.

Q: Are all three parts RoHS compliant?

A: Yes. BZ-2RW84462-A2 is RoHS Compliant, while GPTCNC11 and TZ-1G are ROHS3 Compliant. All three parts meet RoHS requirements.

Q: What is the inventory status of these parts?

A: BZ-2RW84462-A2 (923 pcs), GPTCNC11 (719 pcs), and TZ-1G (1038 pcs) are all available as new original stock.

Q: How do operating temperature ranges compare?

A: BZ-2RW84462-A2 operates from -55°C to 85°C. GPTCNC11 operates from 0°C to 55°C (narrower range). TZ-1G operates from -65°C to 400°C (extended range). Application temperature requirements determine suitability.

Q: What packaging formats are available?

A: BZ-2RW84462-A2 is supplied in standard packaging. GPTCNC11 is supplied in bulk packaging. TZ-1G is supplied in tray packaging. Packaging selection may affect procurement and handling procedures.
