BM-1RW82-A2 Equivalent & Substitute Parts

Part Overview

The BM-1RW82-A2 is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with a 22A AC rating at 125V. This component features a lever roller actuator and screw terminal termination, suitable for on-momentary switching operations. The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing system maintenance and new design implementations. The part maintains RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BM-1RW82-A2 is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Circuit configuration must remain SPDT
• Switch function must support On-Momentary operation
• Voltage rating must equal or exceed 125V AC
• Current rating must equal or exceed 22A AC

Mechanical Compatibility Criteria:

• Actuator type must include roller functionality
• Termination style must be screw terminal
• Mechanical life must meet or exceed 20,000,000 cycles
• Operating temperature range must encompass the application requirements

Regulatory Compliance:

• RoHS compliance status must be maintained
• MSL rating must be 1 (Unlimited)

The GPTBRH11 from ZF Electronics is identified as a substitute component based on matching SPDT circuit configuration, On-Momentary function, 125V AC voltage rating, screw terminal termination, and equivalent mechanical life specification. However, the current rating differential and mounting type variation require engineering evaluation for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The GPTBRH11 serves as an active substitute for the obsolete BM-1RW82-A2, with the following engineering considerations:

Electrical Compatibility: Both components maintain SPDT configuration and 125V AC voltage rating. The GPTBRH11 current rating of 20A is 2A lower than the BM-1RW82-A2 specification of 22A. Applications requiring the full 22A capacity must evaluate whether the 20A rating is acceptable for the specific load conditions.

Mechanical Compatibility: Both components provide equivalent mechanical life of 20,000,000 cycles and screw terminal termination. The actuator type differs (lever roller versus roller plunger), and the mounting configuration changes from chassis mount to panel mount. These differences require mechanical integration assessment for the target application.

Temperature Operating Range: The GPTBRH11 operates within 0°C to 55°C, which is narrower than the BM-1RW82-A2 range of -55°C to 85°C. Applications requiring extended low-temperature operation below 0°C or high-temperature operation above 55°C cannot use the GPTBRH11 as a direct substitute.

Regulatory Status: Both components maintain RoHS compliance and unlimited MSL rating. The GPTBRH11 carries ROHS3 certification, representing current regulatory alignment. The transition from obsolete to active product status ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the GPTBRH11 directly replace the BM-1RW82-A2 in all applications?

A: No. The GPTBRH11 has a lower current rating (20A versus 22A), narrower operating temperature range (0°C to 55°C versus -55°C to 85°C), and different mounting type (panel mount versus chassis mount). Substitution is valid only when the application requirements fall within these GPTBRH11 specifications.

Q: What is the significance of the current rating difference between 22A and 20A?

A: The 2A difference represents a 9% reduction in current capacity. Applications operating near the 22A limit may exceed the GPTBRH11 rating. Load analysis is required to determine if 20A capacity is sufficient for the specific circuit.

Q: How does the mounting type change affect substitution?

A: The BM-1RW82-A2 uses chassis mount configuration, while the GPTBRH11 uses panel mount. These require different mechanical installation approaches. Chassis mount components attach to internal chassis structures, whereas panel mount components attach to external panel surfaces. Mechanical redesign may be necessary.

Q: Why is the operating temperature range narrower for the GPTBRH11?

A: The GPTBRH11 operates from 0°C to 55°C, compared to the BM-1RW82-A2 range of -55°C to 85°C. Applications requiring operation below 0°C or above 55°C cannot use the GPTBRH11. Environmental conditions must be evaluated before substitution.

Q: Are both components RoHS compliant?

A: Yes. The BM-1RW82-A2 is RoHS Compliant, and the GPTBRH11 is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What is the packaging difference between these components?

A: The BM-1RW82-A2 is supplied with standard packaging, while the GPTBRH11 is supplied in bulk packaging. Bulk packaging may affect handling, storage, and inventory management procedures.

Q: Why is the BM-1RW82-A2 classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The GPTBRH11, classified as active, ensures continued availability and supply chain support for new designs and maintenance applications.
