BME6-2RN373 Equivalent & Substitute Parts

Part Overview

The BME6-2RN373 is a snap action SPDT (Single Pole Double Throw) switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis-mounted switch is rated for 22A AC at 125V and features a round pin plunger actuator with screw terminal connections. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing maintenance, repair, and system continuity. The BME6-2RN373 operates within the E6 series and maintains IP66 ingress protection for dust-tight and water-resistant applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BME6-2RN373 is determined by strict equivalence across the following critical parameters:

Circuit and Electrical Specifications: The substitute part must maintain SPDT circuit configuration with identical current ratings of 22A AC and 500mA DC, and voltage ratings of 125V AC and 125V DC.

Mechanical and Physical Characteristics: The substitute must feature the same round pin plunger actuator type, chassis mount configuration, and screw terminal termination style. Operating force (255 ~ 680gf), release force (113gf), and all travel specifications (operating position, pretravel, differential travel, and overtravel) must be identical.

Environmental and Compliance Requirements: The substitute must maintain IP66 ingress protection rating, operate within the -32°C ~ 71°C temperature range, and comply with RoHS standards with MSL rating of 1.

Series Compatibility: The substitute part must belong to the Honeywell E6 series to ensure mechanical and electrical compatibility within existing designs.

Parameter Comparison

Engineering Selection Recommendations

The BME6-2RN serves as a direct equivalent substitute for the obsolete BME6-2RN373. Both parts are manufactured by Honeywell Sensing and Productivity Solutions and share identical electrical, mechanical, and environmental specifications across all critical parameters.

The primary distinction between these parts is product status: the BME6-2RN373 is classified as obsolete, while the BME6-2RN maintains active product status. This status difference reflects manufacturing and supply chain considerations rather than functional or performance differences.

From an engineering perspective, the BME6-2RN is suitable for direct replacement in applications currently using the BME6-2RN373. Both parts maintain RoHS compliance and identical MSL ratings, ensuring compatibility with modern manufacturing and environmental standards. The active status of the BME6-2RN provides improved availability and supply chain continuity for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the BME6-2RN directly replace the BME6-2RN373 in existing applications?

A: Yes. The BME6-2RN is a direct equivalent substitute. All electrical ratings (22A AC, 500mA DC, 125V AC/DC), mechanical specifications (actuator type, mounting, termination), and environmental parameters (IP66, operating temperature, RoHS compliance) are identical between the two parts.

Q: What is the significance of the product status difference between these parts?

A: The BME6-2RN373 is classified as obsolete, indicating it is no longer in active production. The BME6-2RN maintains active status, meaning it is currently manufactured and available through standard supply channels. For new designs and ongoing production, the BME6-2RN is the recommended selection.

Q: Are there any differences in mechanical compatibility?

A: No. Both parts feature identical chassis mount configurations, screw terminal termination, and round pin plunger actuators. Operating force, release force, and all travel specifications are identical, ensuring mechanical interchangeability.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the BME6-2RN373 and BME6-2RN are RoHS compliant with MSL rating of 1 (Unlimited). Both maintain IP66 ingress protection and operate within the -32°C ~ 71°C temperature range.

Q: What is the inventory status of these parts?

A: The BME6-2RN373 has 756 pieces in stock as new original inventory. The BME6-2RN has 911 pieces in stock as new original inventory. Availability may vary based on current supply conditions.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are rated for identical AC and DC current and voltage specifications. The SPDT circuit configuration and On-Mom switch function are identical.
