BZG1-2RN Equivalent & Substitute Parts

Part Overview

The BZG1-2RN is a snap action switch manufactured by Honeywell Sensing and Productivity Solutions, configured as a Single Pole Double Throw (SPDT) device with momentary operation. This switch is rated for 15A AC at 125V and features a round pin plunger actuator with chassis mount configuration and screw terminal termination. The product is designated as Not For New Designs, making identification of functionally equivalent alternatives necessary for ongoing maintenance, repair, and legacy system support applications.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Equivalence: Circuit configuration (SPDT), switch function (On-Momentary), current rating (15A AC / 500mA DC), and voltage rating (125V AC/DC) must match exactly.

Mechanical Equivalence: Actuator type (round pin plunger), mounting method (chassis mount), and termination style (screw terminal) must be identical to ensure physical and electrical compatibility within the existing assembly.

Environmental Compliance: RoHS compliance status and moisture sensitivity level must be maintained to satisfy regulatory and reliability requirements.

The ZV2-N-2S from Omron Automation and Safety meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ZV2-N-2S from Omron Automation and Safety is a qualified direct substitute for the BZG1-2RN. Both components are RoHS compliant and carry MSL 1 rating, satisfying regulatory and environmental requirements.

The ZV2-N-2S offers the following advantages: Active product status ensures continued manufacturer support and availability, extended operating temperature range (-10°C to 80°C versus -32°C to 71°C), and IP65 ingress protection rating providing enhanced environmental sealing compared to the unspecified protection level of the BZG1-2RN.

All critical electrical and mechanical parameters are equivalent, confirming functional interchangeability in SPDT momentary switch applications rated for 15A AC at 125V with chassis mount and screw terminal configuration.

Frequently Asked Questions (FAQ)

Q: Can the ZV2-N-2S replace the BZG1-2RN in existing assemblies?

A: Yes. Both components share identical circuit configuration (SPDT), switch function (On-Momentary), current and voltage ratings (15A AC / 500mA DC at 125V), actuator type (round pin plunger), mounting method (chassis mount), and termination style (screw terminal). Physical and electrical compatibility is confirmed.

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

A: The ZV2-N-2S provides IP65 ingress protection (dust tight, water resistant) compared to unspecified protection on the BZG1-2RN. The ZV2-N-2S also operates across a wider temperature range (-10°C to 80°C) and carries Active product status, whereas the BZG1-2RN is designated Not For New Designs.

Q: Are both switches RoHS compliant?

A: Yes. Both the BZG1-2RN and ZV2-N-2S are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging format for these switches?

A: Both components are supplied in Bulk packaging format.

Q: Does the ZV2-N-2S require any modifications for installation?

A: No modifications are required. The ZV2-N-2S is a direct mechanical and electrical substitute with identical mounting and termination specifications.
