GPTCLS11 Equivalent & Substitute Parts

Part Overview

The GPTCLS11 is a snap action SPDT switch manufactured by ZF Electronics, rated for 15A at 125V AC with chassis mount configuration and screw terminal termination. This switch is currently in active product status with 1,119 units in stock. The lever-actuated design with straight actuator provides reliable on-momentary switching functionality across industrial and commercial applications.

Substitute parts are identified based on matching electrical ratings, mechanical specifications, and form factor compatibility. Alternative sources may be required due to supply chain considerations, manufacturing availability, or design standardization across component families.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Electrical Compatibility: Current rating (AC/DC), voltage rating (AC/DC), and circuit configuration (SPDT)
• Mechanical Compatibility: Actuator type (lever, straight), mounting type (chassis mount), and termination style (screw terminal)
• Operational Specifications: Operating force, release force, differential travel, and mechanical life cycle rating
• Environmental Compliance: RoHS status and operating temperature range

Parts are grouped into two categories:

Full Equivalents (BZ-2RW855051-A2-S, BZ-2RWT80): Match the primary electrical ratings (15A AC, 125V AC), mechanical specifications (71gf operating force, 14gf release force), and form factor. These parts are suitable for direct substitution in applications where the GPTCLS11 is specified.

Partial Equivalents (BZ-2RW84T): Match electrical ratings and form factor but differ in operating force (28gf vs. 71gf) and release force (4.6gf vs. 14gf). This part is obsolete and suitable only where force characteristics are not critical.

Non-Equivalent (SCN-2623SC): Current rating of 1A AC does not meet the 15A requirement and is not suitable for substitution.

Parameter Comparison

Engineering Selection Recommendations

Recommended Substitutes (Active Status)

BZ-2RW855051-A2-S and BZ-2RWT80 are both active products from Honeywell Sensing and Productivity Solutions. Both parts match the GPTCLS11 in electrical ratings (15A AC, 125V AC), mechanical specifications (71gf operating force, 14gf release force), and form factor. These parts are suitable for direct substitution where the GPTCLS11 is specified. The extended operating temperature range (-55°C to 85°C) provides broader environmental capability compared to the GPTCLS11 (0°C to 55°C).

Conditional Substitute (Obsolete Status)

BZ-2RW84T is an obsolete Honeywell product that matches electrical ratings and form factor but differs in operating force (28gf) and release force (4.6gf). This part should be used only in applications where actuator force characteristics are not critical to system performance.

Non-Suitable Alternative

SCN-2623SC does not meet the 15A current requirement and is not suitable for substitution.

Frequently Asked Questions (FAQ)

Q: Can BZ-2RW855051-A2-S directly replace GPTCLS11 in existing designs?

A: Yes. Both parts share identical electrical ratings (15A AC, 125V AC), SPDT circuit configuration, on-momentary function, and mechanical specifications (71gf operating force, 14gf release force). The chassis mount configuration and screw terminal termination are identical. The operating position differs by 0.035" (0.9mm), which is within typical mechanical tolerance for chassis-mounted switches.

Q: What is the significance of the operating force difference between GPTCLS11 and BZ-2RW84T?

A: Operating force (71gf vs. 28gf) and release force (14gf vs. 4.6gf) determine the actuation effort required. The GPTCLS11 requires greater force to actuate and release. BZ-2RW84T is suitable only for applications where lower actuation force is acceptable or required.

Q: Are there DC voltage ratings for the GPTCLS11?

A: No DC voltage rating is specified for GPTCLS11. The part is rated for 125V AC only. Honeywell substitutes BZ-2RW855051-A2-S and BZ-2RWT80 are rated for both 125V AC and 125V DC with 500mA DC current capability.

Q: What is the impact of the extended temperature range in Honeywell substitutes?

A: Honeywell parts (BZ-2RW855051-A2-S, BZ-2RWT80, BZ-2RW84T) operate from -55°C to 85°C, compared to GPTCLS11's 0°C to 55°C range. This provides broader environmental capability for applications requiring operation in extreme temperatures. However, the GPTCLS11 is sufficient for applications within its specified range.

Q: Why is SCN-2623SC listed as non-equivalent?

A: SCN-2623SC is rated for 1A AC, which does not meet the 15A AC requirement of GPTCLS11. Current rating is a critical electrical parameter that cannot be exceeded without risk of component failure or fire hazard.

Q: Are all substitute parts RoHS compliant?

A: Yes. GPTCLS11 is ROHS3 compliant. All Honeywell substitutes (BZ-2RW855051-A2-S, BZ-2RWT80, BZ-2RW84T) are RoHS compliant, meeting environmental regulatory requirements.
