BZ-2RW82255T-S Equivalent & Substitute Parts

Part Overview

The BZ-2RW82255T-S 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 features a lever roller actuator with screw terminal connections. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and new design applications where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the BZ-2RW82255T-S is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• Current rating: 15A AC minimum
• Voltage rating: 125V AC minimum
• Actuator type: Lever with roller
• Mounting type: Chassis mount
• Termination style: Screw terminal
• Mechanical life: 20,000,000 cycles minimum

Acceptable Variation Parameters:

• Operating force: Within ±15% tolerance (158gf to 185gf acceptable)
• Operating position: Within ±0.05" tolerance
• Differential travel: 0.020" (0.5mm) standard
• Overtravel: 0.094" (2.4mm) standard

The substitute parts GPTCRM01 and GPTCRM11 (both ZF Electronics) meet the mandatory matching parameters. Both are manufactured by ZF Electronics under the GP series and maintain identical electrical specifications for AC operation at 15A and 125V.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

Both GPTCRM01 and GPTCRM11 from ZF Electronics are functionally equivalent to the obsolete BZ-2RW82255T-S for AC applications at 15A and 125V. Both substitute parts are currently in active production status, ensuring long-term availability and supply chain continuity.

Compliance Considerations:

The BZ-2RW82255T-S carries RoHS Compliant certification. Both substitute parts (GPTCRM01 and GPTCRM11) carry ROHS3 Compliant certification, which represents a higher standard of environmental compliance and is fully backward compatible with RoHS requirements.

Temperature Range Limitation:

The substitute parts operate within 0°C to 55°C, which is narrower than the original part's -55°C to 85°C range. Applications requiring operation below 0°C or above 55°C cannot use these substitutes without design modification or alternative component selection.

Operating Force Differential:

The substitute parts specify 158gf operating force compared to the original 170gf. This 7% reduction falls within acceptable mechanical tolerance for equivalent snap action switch operation and does not affect electrical performance or switching reliability.

Inventory Availability:

GPTCRM01: 1,079 pieces in stock GPTCRM11: 907 pieces in stock

Both parts are available in bulk packaging and maintain identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can GPTCRM01 and GPTCRM11 be used interchangeably with BZ-2RW82255T-S?

A: Yes, for applications operating within 0°C to 55°C at 15A and 125V AC. Both ZF Electronics parts maintain identical SPDT circuit configuration, on-momentary switch function, lever roller actuator, chassis mount configuration, and screw terminal termination. Mechanical life ratings and differential travel specifications are identical.

Q: What is the difference between GPTCRM01 and GPTCRM11?

A: Both parts are manufactured by ZF Electronics under the GP series and carry identical electrical and mechanical specifications. No functional difference exists between these two part numbers for the parameters provided.

Q: Why does the operating temperature range differ between the original and substitute parts?

A: The substitute parts from ZF Electronics are rated for 0°C to 55°C operation, while the original Honeywell part operates from -55°C to 85°C. This represents a design difference between manufacturers. Applications requiring the full -55°C to 85°C range cannot use these substitutes.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both GPTCRM01 and GPTCRM11 carry ROHS3 Compliant certification, which exceeds the RoHS Compliant status of the original BZ-2RW82255T-S and is fully compatible with RoHS requirements.

Q: Does the 12gf difference in operating force affect switch performance?

A: No. The substitute parts specify 158gf operating force versus the original 170gf. This 7% variation is within standard mechanical tolerance for snap action switches and does not affect electrical switching performance, contact reliability, or cycle life.

Q: What packaging is available for the substitute parts?

A: Both GPTCRM01 and GPTCRM11 are supplied in bulk packaging, as opposed to the original part's standard packaging designation.

Q: Can these switches be used in DC applications?

A: The substitute parts are rated for 15A AC only. The original BZ-2RW82255T-S is rated for 15A AC and 500mA DC. If DC operation is required, the substitute parts are not suitable.

Q: Are all three parts (original and two substitutes) classified under the same HTSUS code?

A: Yes. All three parts share HTSUS code 8536.50.9040 and EAR99 ECCN classification, confirming their functional equivalence for tariff and export control purposes.
