BZ-RLX Equivalent & Substitute Parts Reference

Part Overview

The BZ-RLX is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a single-pole double-throw (SPDT) device with chassis mount installation. This component operates at 15A AC with 125V rating and features a lever actuator with solder lug termination. The BZ-RLX is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy component specifications must be maintained or adapted.

Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the BZ-RLX is constrained by the following critical parameters that must align between the main part and any equivalent alternative:

Circuit Configuration: Both the main part and substitute must maintain SPDT topology to preserve electrical functionality within the host system.

Mounting Interface: Chassis mount configuration is mandatory for physical compatibility with existing enclosure designs and PCB layouts.

Termination Method: Solder lug termination is required to match existing wiring and connection infrastructure.

Actuator Mechanism: Lever-type actuation ensures compatibility with mechanical activation systems and operator interfaces.

Environmental Specifications: Operating temperature range and mechanical cycle life establish baseline durability requirements for the application environment.

The X-10GL from Omron Automation and Safety is identified as a substitute part. However, this substitution involves parameter deviations that must be evaluated against specific application requirements. The X-10GL operates at reduced current (10A DC versus 15A AC) and voltage (30V DC versus 125V AC), indicating this substitute is suitable only for applications with lower electrical demands than the original BZ-RLX specification.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The BZ-RLX is classified as obsolete, indicating discontinued manufacturing and limited availability. The X-10GL maintains active product status with current manufacturing support from Omron Automation and Safety, providing supply chain continuity for future procurement requirements.

Compliance and Certification: Both components meet RoHS requirements. The BZ-RLX carries RoHS Compliant designation, while the X-10GL meets ROHS3 Compliant standards. The X-10GL additionally carries REACH Affected status, indicating compliance with European chemical regulations. Both components are classified under ECCN EAR99 for export control purposes.

Electrical Parameter Deviations: The X-10GL operates at 10A DC and 30V DC, representing significant reductions from the BZ-RLX specification of 15A AC and 125V AC. Selection of the X-10GL is restricted to applications where the lower electrical ratings are compatible with system requirements. Direct substitution in circuits designed for the full 15A AC and 125V AC capability is not supported.

Mechanical and Operational Differences: The X-10GL requires higher operating force (200gf versus 85gf), exhibits larger differential travel (0.090" versus 0.030"), and demonstrates substantially lower mechanical life (1,000,000 cycles versus 20,000,000 cycles). These differences affect actuator responsiveness, switching precision, and long-term reliability in high-cycle applications.

Temperature Range: The X-10GL operates within -25°C to 80°C, which is narrower than the BZ-RLX range of -55°C to 85°C. Applications requiring operation at temperatures below -25°C or above 80°C cannot use the X-10GL as a substitute.

Switch Function: The BZ-RLX operates as On-On, while the X-10GL functions as On-Mom (momentary). This functional difference affects circuit behavior and must be evaluated against application logic requirements.

Frequently Asked Questions (FAQ)

Q: Can the X-10GL directly replace the BZ-RLX in all applications?

A: No. The X-10GL has reduced electrical ratings (10A DC at 30V DC versus 15A AC at 125V AC), narrower operating temperature range (-25°C to 80°C versus -55°C to 85°C), and lower mechanical life (1,000,000 cycles versus 20,000,000 cycles). Substitution is valid only when the application requirements fall within the X-10GL specifications.

Q: What are the key electrical differences between these parts?

A: The BZ-RLX is rated for 15A AC at 125V AC, while the X-10GL is rated for 10A DC at 30V DC. The BZ-RLX supports higher current and voltage levels. Additionally, the BZ-RLX operates as On-On, while the X-10GL functions as On-Mom (momentary).

Q: How do the mechanical characteristics differ?

A: The BZ-RLX requires 85gf operating force with 0.030" differential travel and supports 20,000,000 mechanical cycles. The X-10GL requires 200gf operating force with 0.090" differential travel and supports 1,000,000 mechanical cycles. The higher operating force and larger differential travel of the X-10GL may affect system responsiveness and precision.

Q: Are both parts RoHS compliant?

A: Yes. The BZ-RLX is RoHS Compliant, and the X-10GL is ROHS3 Compliant. Both meet lead-free and hazardous substance restrictions. The X-10GL additionally carries REACH Affected status for European chemical compliance.

Q: What is the temperature operating range for each part?

A: The BZ-RLX operates from -55°C to 85°C. The X-10GL operates from -25°C to 80°C. Applications requiring operation below -25°C or above 80°C cannot use the X-10GL.

Q: How do the packaging and availability differ?

A: The BZ-RLX is obsolete with limited remaining inventory (1,098 pieces). The X-10GL is an active product supplied in tray packaging with current inventory of 760 pieces. The X-10GL provides ongoing supply chain access.

Q: What mounting and termination compatibility exists?

A: Both parts feature chassis mount installation and solder lug termination, ensuring mechanical and electrical interface compatibility. Operating position measurements are nearly identical (0.689" for BZ-RLX versus 0.685" for X-10GL), supporting physical interchangeability in mounting applications.

Q: Can the X-10GL be used in high-cycle applications?

A: The X-10GL supports 1,000,000 mechanical cycles, which is significantly lower than the BZ-RLX rating of 20,000,000 cycles. Applications requiring extended cycle life should evaluate whether the X-10GL meets durability requirements.
