Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-2RW855T-S is determined by the following critical parameters:

Primary Substitution Criteria:

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

Secondary Compatibility Factors:

• Operating force and release force alignment (71gf and 14gf respectively)
• Differential travel: 0.050" (1.3mm)
• Overtravel: 0.219" (5.6mm)
• RoHS compliance status

The GPTCLS11 manufactured by ZF Electronics meets the primary substitution criteria for SPDT circuit configuration, On-Momentary function, 15A AC current rating, 125V AC voltage rating, lever straight actuator, chassis mount configuration, and screw terminal termination. Operating force, release force, differential travel, and overtravel specifications are identical. The substitute part maintains 20,000,000 mechanical life cycles and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The GPTCLS11 is a direct functional equivalent to the BZ-2RW855T-S for applications operating within the overlapping temperature range of 0°C to 55°C. Both parts are RoHS compliant and share identical electrical ratings, mechanical specifications, and circuit configurations.

Selection Basis:

The BZ-2RW855T-S is classified as obsolete, while the GPTCLS11 is active in production. The substitute part maintains all critical electrical and mechanical parameters required for SPDT snap action switching at 15A AC and 125V AC ratings.

Temperature Consideration:

The main part operates from -55°C to 85°C, while the substitute operates from 0°C to 55°C. Applications requiring operation below 0°C or above 55°C cannot use the GPTCLS11 as a direct substitute without additional thermal management evaluation.

Compliance Status:

Both parts meet RoHS requirements. The GPTCLS11 carries ROHS3 compliance, which represents current RoHS standards. The main part carries RoHS Compliant status. Both parts are classified under ECCN EAR99 and HTSUS 8536.50.9040.

Frequently Asked Questions (FAQ)

Q: Can the GPTCLS11 replace the BZ-2RW855T-S in all applications?

A: The GPTCLS11 is functionally equivalent for applications operating within 0°C to 55°C. Applications requiring the full -55°C to 85°C temperature range of the original part require evaluation of alternative substitutes or thermal management solutions.

Q: What are the key electrical parameters that determine substitution compatibility?

A: The critical parameters are circuit configuration (SPDT), switch function (On-Momentary), current rating (15A AC), voltage rating (125V AC), actuator type (Lever, Straight), mounting type (Chassis Mount), and termination style (Screw Terminal). The GPTCLS11 matches all these parameters.

Q: Are the mechanical specifications identical between the two parts?

A: Yes. Operating force (71gf), release force (14gf), differential travel (0.050"), overtravel (0.219"), and mechanical life (20,000,000 cycles) are identical between the BZ-2RW855T-S and GPTCLS11.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate RoHS compliance. ROHS3 represents the current RoHS 3 directive standard. Both parts meet hazardous substance restrictions and are suitable for applications requiring RoHS compliance.

Q: Does packaging differ between the main part and substitute?

A: The BZ-2RW855T-S is listed with dash packaging notation, while the GPTCLS11 is supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the operating position difference between these parts?

A: The BZ-2RW855T-S has an operating position of 0.750" (19.1mm), while the GPTCLS11 has 0.715" (18.2mm). This 0.035" difference may affect mechanical integration in space-constrained applications.

Q: Are both parts splash-proof?

A: The BZ-2RW855T-S specifies splash-proof ingress protection. The GPTCLS11 does not specify ingress protection rating in the provided data. Verify environmental protection requirements for your application.
