Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GPTCRH11 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• Termination style must be Screw Terminal
• Mechanical life must meet or exceed 20,000,000 cycles
• RoHS compliance status must be maintained

Secondary Compatibility Criteria (Application-Dependent):

• Current rating: 15A AC minimum
• Voltage rating: 125V AC minimum
• Actuator type: Roller Plunger preferred for mechanical consistency
• Mounting type: Panel Mount preferred; Chassis Mount acceptable with mechanical adaptation
• Operating temperature range: Must encompass 0°C to 55°C minimum

The following parts meet primary compatibility criteria and are classified as direct substitutes:

• BZ-2RQ181T (Honeywell): Identical circuit, function, current, voltage, actuator, mounting, and termination
• BZ-2RQ18T (Honeywell): Identical circuit, function, current, voltage, actuator, mounting, and termination
• Z-15HQ22-B (Omron): Identical circuit, function, current, voltage, actuator, mounting, and termination

The following parts meet primary compatibility criteria with parameter variations:

• BZ-3YQ8T (Honeywell): Reduced current rating (5A) and increased voltage rating (250V); suitable only for applications not requiring 15A capacity
• BM-1RQ18124-A2 (Honeywell): Increased current rating (22A), different mounting type (Chassis Mount), and extended temperature range; requires mechanical adaptation

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (No Application Modification Required):

BZ-2RQ181T and BZ-2RQ18T from Honeywell Sensing and Productivity Solutions are functionally equivalent to GPTCRH11. Both parts maintain identical electrical ratings (15A, 125V AC), circuit configuration (SPDT), actuator type (Roller Plunger), mounting style (Panel Mount), and termination method (Screw Terminal). Both are RoHS compliant and rated for 20,000,000 mechanical cycles. Operating temperature ranges exceed the GPTCRH11 specification, providing extended performance margin. These substitutes are suitable for direct replacement without circuit or mechanical redesign.

Z-15HQ22-B from Omron Automation and Safety meets all primary compatibility criteria with identical electrical and mechanical specifications. This part is RoHS3 compliant and includes IP00 ingress protection rating. Operating temperature range (-25°C to 80°C) encompasses the GPTCRH11 operating window. Electrical life specification of 500,000 cycles is provided for this part. Direct substitution is supported.

Conditional Substitutes (Application-Specific Evaluation Required):

BZ-3YQ8T is suitable only for applications where current demand does not exceed 5A. The increased voltage rating (250V) and higher operating force (454-737gf) indicate this part is designed for different load conditions. Substitution requires verification that circuit current requirements remain below 5A maximum rating.

BM-1RQ18124-A2 features increased current capacity (22A) and extended temperature range (-55°C to 121°C), making it suitable for high-current or extreme-temperature applications. However, Chassis Mount configuration requires mechanical redesign compared to Panel Mount GPTCRH11. This substitution is appropriate only when mounting configuration can be accommodated and higher current capacity is beneficial or required.

Frequently Asked Questions (FAQ)

Q: Can BZ-2RQ181T and BZ-2RQ18T be used interchangeably with GPTCRH11?

A: Yes. Both Honeywell parts are direct substitutes. They share identical circuit configuration (SPDT), current rating (15A AC), voltage rating (125V AC), actuator type (Roller Plunger), mounting type (Panel Mount), and termination style (Screw Terminal). Mechanical life ratings are equivalent at 20,000,000 cycles. No circuit or mechanical modifications are required.

Q: What is the difference between BZ-2RQ181T and BZ-2RQ18T?

A: Both parts are functionally identical in electrical and mechanical specifications. The primary difference is packaging: BZ-2RQ181T packaging is not specified in available data, while BZ-2RQ18T is supplied in Bulk packaging. Electrical performance and physical dimensions are equivalent.

Q: Is Z-15HQ22-B compatible with GPTCRH11 applications?

A: Yes. Z-15HQ22-B meets all primary compatibility requirements: SPDT circuit, On-Momentary function, 15A AC rating, 125V AC rating, Roller Plunger actuator, Panel Mount configuration, and Screw Terminal termination. The part is RoHS3 compliant and rated for 20,000,000 mechanical cycles. Operating temperature range (-25°C to 80°C) fully encompasses GPTCRH11 specification (0°C to 55°C).

Q: When should BZ-3YQ8T be considered as a substitute?

A: BZ-3YQ8T is appropriate only for applications where maximum circuit current does not exceed 5A. This part features 250V AC rating and higher operating force compared to GPTCRH11. Substitution requires confirmation that application current demand is below 5A maximum rating. If 15A capacity is required, this part is not suitable.

Q: Can BM-1RQ18124-A2 replace GPTCRH11 in existing designs?

A: BM-1RQ18124-A2 can replace GPTCRH11 functionally but requires mechanical redesign. The primary difference is mounting type: BM-1RQ18124-A2 uses Chassis Mount configuration while GPTCRH11 uses Panel Mount. Additionally, BM-1RQ18124-A2 features Cross Roller Plunger actuator versus standard Roller Plunger. This substitution is appropriate when higher current capacity (22A) is beneficial and mechanical adaptation is feasible.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain RoHS compliance. GPTCRH11 and Z-15HQ22-B are RoHS3 compliant. BZ-2RQ181T, BZ-2RQ18T, BZ-3YQ8T, and BM-1RQ18124-A2 are RoHS compliant. Compliance status is maintained across all substitution options.

Q: What mechanical life rating should be expected from substitute parts?

A: All substitute parts are rated for 20,000,000 mechanical cycles, matching GPTCRH11 specification. This rating applies to BZ-2RQ181T, BZ-2RQ18T, Z-15HQ22-B, BZ-3YQ8T, and BM-1RQ18124-A2. Electrical life specifications vary by manufacturer and part design; refer to individual datasheets for electrical life ratings where applicable.
