BZ-RQ66 Equivalent & Substitute Parts Reference

Part Overview

The BZ-RQ66 is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a single-pole double-throw (SPDT) panel mount device rated for 15A at 125V AC. This switch features an overtravel plunger actuator with screw terminal connections and is designed for on-momentary switch function applications.

The BZ-RQ66 carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZ-RQ66 are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Primary Electrical Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Current rating: 15A (AC)
• Voltage rating: 125V AC

Primary Mechanical Parameters:

• Actuator type: Overtravel Plunger
• Mounting type: Panel Mount
• Termination style: Screw Terminal
• Mechanical life: 20,000,000 Cycles

Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level (MSL): 1 (Unlimited)

The substitute parts GPTCNH01 and GPTCNH11 (both manufactured by ZF Electronics) satisfy all primary electrical and mechanical requirements. Both parts maintain the same circuit configuration, current and voltage ratings, actuator type, mounting configuration, and termination style. Both achieve equivalent mechanical life specifications and maintain MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both GPTCNH01 and GPTCNH11 substitute parts are manufactured by ZF Electronics and carry active product status, ensuring long-term availability and supply chain continuity. Both parts maintain ROHS3 compliance, exceeding the RoHS compliance level of the obsolete BZ-RQ66.

The GPTCNH11 variant is recommended as the primary substitute due to higher current inventory availability (1099 pieces in stock) compared to GPTCNH01 (771 pieces in stock). Both parts are supplied in bulk packaging and are functionally equivalent for applications requiring SPDT 15A 125V AC snap action switches with panel mount configuration and screw terminal connections.

The operating temperature range of the substitute parts (0°C to 55°C) is narrower than the BZ-RQ66 (-55°C to 85°C). Applications requiring operation outside the 0°C to 55°C range require evaluation of alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can GPTCNH01 and GPTCNH11 be used interchangeably with BZ-RQ66?

A: Both ZF Electronics parts satisfy the core electrical and mechanical requirements: SPDT circuit, 15A at 125V AC rating, overtravel plunger actuator, panel mount configuration, and screw terminal termination. Both achieve 20,000,000 cycle mechanical life and MSL 1 rating. Substitution is valid for applications operating within the 0°C to 55°C temperature range.

Q: What are the key differences between GPTCNH01 and GPTCNH11?

A: GPTCNH01 and GPTCNH11 are functionally identical. Both are manufactured by ZF Electronics, share the same base product number (GPTCNH), and provide identical electrical and mechanical specifications. The primary difference is inventory availability, with GPTCNH11 currently stocked at higher quantities.

Q: Are there temperature limitations when substituting with GPTCNH01 or GPTCNH11?

A: Yes. The substitute parts operate within 0°C to 55°C, while the BZ-RQ66 operates from -55°C to 85°C. Applications requiring operation below 0°C or above 55°C cannot use these substitutes without additional evaluation.

Q: Do the substitute parts maintain RoHS compliance?

A: Both GPTCNH01 and GPTCNH11 are ROHS3 compliant, which exceeds the RoHS compliance requirement of the BZ-RQ66. No compliance degradation occurs with substitution.

Q: What packaging is available for the substitute parts?

A: Both GPTCNH01 and GPTCNH11 are supplied in bulk packaging.
