BZG1-2RN2 Equivalent & Substitute Parts

Part Overview

The BZG1-2RN2 is a snap action SPDT switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis mount switch is rated for 15A AC at 125V and 500mA DC at 125V, featuring a lever roller actuator with screw terminal connections. The product is designated as Not For New Designs, indicating that alternative components should be evaluated for new applications. Identifying equivalent substitute parts ensures design flexibility and supply chain continuity when the primary component becomes unavailable or when design requirements necessitate active product alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BZG1-2RN2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: The substitute part must maintain identical circuit configuration (SPDT), switch function (On-Momentary), current ratings (15A AC / 500mA DC), and voltage ratings (125V AC / 125V DC).

Mechanical Equivalence: The substitute part must feature the same actuator type (Lever, Roller), mounting configuration (Chassis Mount), and termination method (Screw Terminal).

Environmental Compliance: The substitute part must maintain RoHS compliance and MSL 1 rating to ensure compatibility with standard manufacturing and storage conditions.

The ZV2-NA2-2S from Omron Automation and Safety meets all these core substitution criteria while offering enhanced specifications in certain operational parameters.

Engineering Selection Recommendations

For Existing Designs Using BZG1-2RN2:

The BZG1-2RN2 remains functionally suitable for applications currently in production. Continued use is supported by adequate inventory (1003 pcs) and full RoHS compliance.

For New Design Implementation:

The ZV2-NA2-2S from Omron Automation and Safety is the recommended substitute. This component is designated as Active product status, ensuring long-term availability and manufacturer support. The ZV2-NA2-2S maintains complete electrical and mechanical equivalence while providing:

• Enhanced ingress protection (IP65 rating)
• Extended upper operating temperature limit (80°C vs. 71°C)
• Documented electrical life (500,000 cycles) and mechanical life (10,000,000 cycles)
• Equivalent RoHS compliance and MSL 1 rating

Both components are certified under ECCN EAR99 and comply with applicable trade regulations.

Frequently Asked Questions (FAQ)

Q: Can ZV2-NA2-2S directly replace BZG1-2RN2 in existing applications?

A: Yes. Both components share identical electrical ratings (15A AC / 500mA DC at 125V), circuit configuration (SPDT), switch function (On-Momentary), actuator type (Lever, Roller), mounting method (Chassis Mount), and termination style (Screw Terminal). Mechanical and electrical performance are equivalent for standard applications.

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

A: The ZV2-NA2-2S features higher operating force (640gf vs. 283-567gf range) and release force (230gf vs. 113gf), along with slightly different travel specifications. The ZV2-NA2-2S also provides IP65 ingress protection and operates across a wider temperature range (-10°C to 80°C vs. -32°C to 71°C). These differences do not affect substitution compatibility for standard switching applications.

Q: Why is BZG1-2RN2 marked as Not For New Designs?

A: This designation indicates the product is in mature or declining production status. Honeywell recommends evaluating alternative components for new development projects. The ZV2-NA2-2S provides an active, supported alternative with equivalent core specifications.

Q: Are there packaging or inventory considerations?

A: Both components are supplied in Bulk packaging. Current inventory shows 1003 pcs of BZG1-2RN2 and 1062 pcs of ZV2-NA2-2S available as new original stock.

Q: Do both switches meet environmental compliance requirements?

A: Yes. Both the BZG1-2RN2 and ZV2-NA2-2S are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard manufacturing and storage environments.
