BZ-2RW84T Equivalent & Substitute Parts

Part Overview

The BZ-2RW84T is a snap action SPDT (Single Pole Double Throw) switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis-mounted switch is rated for 15A at 125V AC and 500mA at 125V DC, featuring a straight lever actuator with screw terminal connections. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and design continuity in applications requiring SPDT switching functionality at these electrical ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZ-2RW84T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

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

Acceptable Variation Parameters:

• Operating force and release force may vary within mechanical design tolerances
• Operating position, pretravel, differential travel, and overtravel may vary within mechanical design tolerances
• Operating temperature range may be narrower in substitutes
• DC voltage and current ratings may differ if AC ratings are met

The GPTCLS11 manufactured by ZF Electronics meets the mandatory matching criteria for circuit configuration, switch function, current rating, voltage rating, actuator type, mounting type, termination style, and mechanical life cycle rating.

Parameter Comparison

Engineering Selection Recommendations

The GPTCLS11 from ZF Electronics is functionally equivalent to the BZ-2RW84T for applications requiring SPDT switching at 15A, 125V AC with on-momentary operation and chassis-mounted screw terminal configuration.

Selection Basis:

The GPTCLS11 satisfies all mandatory electrical and mechanical parameters: identical circuit configuration (SPDT), switch function (On-Momentary), current rating (15A AC), voltage rating (125V AC), actuator type (Lever, Straight), mounting type (Chassis Mount), termination style (Screw Terminal), and mechanical life rating (20,000,000 cycles).

Compliance Status:

Both parts meet RoHS requirements. The BZ-2RW84T carries RoHS Compliant certification, while the GPTCLS11 carries ROHS3 Compliant certification, indicating updated compliance with current RoHS standards.

Operational Considerations:

The GPTCLS11 exhibits higher operating force (71gf versus 28gf) and higher release force (14gf versus 3.500gf), requiring greater actuation effort. The substitute also demonstrates greater pretravel (0.394" versus 0.328"), which may affect response timing in applications sensitive to actuation lag.

The GPTCLS11 operates within a narrower temperature range (0°C to 55°C) compared to the BZ-2RW84T (-55°C to 85°C). Applications requiring operation below 0°C or above 55°C cannot use this substitute.

The GPTCLS11 is currently in active production status, ensuring ongoing availability and supply chain continuity compared to the obsolete BZ-2RW84T.

Frequently Asked Questions (FAQ)

Q: Can the GPTCLS11 directly replace the BZ-2RW84T in all applications?

A: The GPTCLS11 is electrically and mechanically equivalent for SPDT switching at 15A, 125V AC with on-momentary operation. However, applications operating below 0°C or above 55°C require the original BZ-2RW84T or an alternative with matching temperature range. Applications sensitive to actuation force or pretravel characteristics should evaluate the mechanical differences documented in the parameter comparison table.

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

A: Both parts are rated for 15A at 125V AC and feature SPDT circuit configuration with on-momentary switching. The BZ-2RW84T specifies 500mA at 125V DC operation; DC ratings are not provided for the GPTCLS11. For applications requiring DC switching capability, verify GPTCLS11 DC specifications with the manufacturer.

Q: How do the mechanical characteristics differ?

A: The GPTCLS11 requires significantly higher operating force (71gf versus 28gf) and release force (14gf versus 3.500gf). The substitute also exhibits greater pretravel (0.394" versus 0.328"). These differences may affect user interface feel and response timing. Differential travel and overtravel are identical between parts.

Q: What is the temperature operating range limitation?

A: The BZ-2RW84T operates from -55°C to 85°C, while the GPTCLS11 operates from 0°C to 55°C. The substitute cannot be used in applications requiring operation below 0°C or above 55°C. Alternative substitutes must be identified for extended temperature range requirements.

Q: Are both parts RoHS compliant?

A: Yes. The BZ-2RW84T carries RoHS Compliant certification, and the GPTCLS11 carries ROHS3 Compliant certification. Both meet RoHS environmental compliance requirements.

Q: What is the packaging difference?

A: The BZ-2RW84T is supplied in standard packaging (packaging type not specified), while the GPTCLS11 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Why is the BZ-2RW84T classified as obsolete?

A: The BZ-2RW84T is no longer in active production by Honeywell. The GPTCLS11 is currently in active production status, ensuring continued availability and supply chain support for equivalent SPDT switching applications.

Q: Can I use the GPTCLS11 in applications requiring DC switching?

A: The GPTCLS11 specifications do not include DC current or voltage ratings. The BZ-2RW84T is rated for 500mA at 125V DC. For applications requiring DC switching capability, contact the manufacturer for GPTCLS11 DC specifications or identify alternative substitutes with documented DC ratings.
