BZ-2RQ233-A2 Equivalent & Substitute Parts

Part Overview

The BZ-2RQ233-A2 is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions. This SPDT (Single Pole Double Throw) panel mount switch is rated for 15A at 125V AC and 500mA at 125V DC, featuring an overtravel plunger actuator with screw terminal connections. The product is Active status and RoHS Compliant. Equivalent and substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative component sourcing while maintaining functional and electrical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the BZ-2RQ233-A2 is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Circuit configuration must be SPDT
• Switch function must be On-Momentary
• AC current rating must be 15A minimum
• AC voltage rating must be 125V minimum
• Actuator type must be overtravel plunger
• Mounting type must be panel mount
• Termination style must be screw terminal
• Mechanical life must be 20,000,000 cycles minimum

Secondary Compatibility Factors:

• Operating temperature range (substitute must cover application requirements)
• RoHS compliance status (must meet or exceed original specification)
• MSL rating (must be 1 or equivalent)

The GPTCNH11 from ZF Electronics meets all primary substitution criteria and is classified as a direct equivalent for the BZ-2RQ233-A2.

Parameter Comparison

Engineering Selection Recommendations

BZ-2RQ233-A2 (Honeywell Sensing and Productivity Solutions):

• Primary selection for applications requiring extended operating temperature range (-55°C to 85°C)
• Specified DC voltage and current ratings (125V DC, 500mA DC) for DC circuit applications
• Active product status with established supply chain
• RoHS Compliant certification

GPTCNH11 (ZF Electronics):

• Suitable for AC applications within 0°C to 55°C operating temperature range
• Direct functional equivalent for standard AC circuit implementations
• ROHS3 Compliant certification
• Higher current inventory availability (1099 Pcs vs 832 Pcs)
• Functionally equivalent mechanical parameters with minor dimensional variations within tolerance

Selection between these parts is determined by application operating temperature requirements and whether DC voltage/current specifications are required. For applications operating below 0°C or above 55°C, the BZ-2RQ233-A2 is the required selection. For AC-only applications within the 0°C to 55°C range, either part is acceptable based on availability and lead time.

Frequently Asked Questions (FAQ)

Q: Can GPTCNH11 replace BZ-2RQ233-A2 in all applications?

A: GPTCNH11 is functionally equivalent for AC applications operating between 0°C and 55°C. Applications requiring DC operation or operating temperatures outside this range require the BZ-2RQ233-A2.

Q: What are the key differences between these two switches?

A: The primary differences are operating temperature range (BZ-2RQ233-A2: -55°C to 85°C; GPTCNH11: 0°C to 55°C) and DC ratings (BZ-2RQ233-A2 specifies 500mA at 125V DC; GPTCNH11 does not specify DC ratings). Mechanical parameters are functionally equivalent with minor dimensional variations.

Q: Are the screw terminal connections identical?

A: Both switches feature screw terminal connections and are mechanically compatible for panel mount installation. Terminal pitch and connection methodology are equivalent.

Q: What does SPDT On-Momentary function mean?

A: SPDT (Single Pole Double Throw) indicates the switch has one moving contact that connects to either of two fixed contacts. On-Momentary function means the switch returns to its normal position when the plunger is released.

Q: Are both parts RoHS compliant?

A: Yes. BZ-2RQ233-A2 is RoHS Compliant. GPTCNH11 is ROHS3 Compliant. Both meet RoHS requirements.

Q: What is the significance of the 20,000,000 cycle mechanical life rating?

A: This rating indicates the switch is rated for 20 million on-off cycles before mechanical degradation. Both parts meet this specification.

Q: How do the operating force specifications compare?

A: BZ-2RQ233-A2 specifies 255 ~ 368gf operating force range. GPTCNH11 specifies 348gf fixed operating force. The GPTCNH11 value falls within the BZ-2RQ233-A2 range, indicating functional equivalence.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture control requirements. Both parts carry MSL 1 rating, eliminating moisture management considerations during storage and handling.
