Honeywell 2CPSA2A2B Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The Honeywell 2CPSA2A2B is a snap action switch from the CPS series, configured as a 4PST (4-pole, single-throw) switch with 2NO/2NC (2 normally open, 2 normally closed) contacts. This component operates at 50mA with 250V AC and 60V DC ratings, featuring a lighted indicator and IP67 ingress protection suitable for dust-tight and waterproof applications across an operating temperature range of -40°C to 80°C.

The 2CPSA2A2B carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this switch configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2CPSA2A2B is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Circuit configuration: 4PST-2NO/2NC contact arrangement
• Current rating: 50mA for both AC and DC operation
• Voltage ratings: 250V AC and 60V DC

Environmental & Mechanical Parameters:

• Ingress protection: IP67 rating (dust tight, waterproof)
• Operating temperature: -40°C to 80°C range
• Lighted indicator feature

Compliance & Quality Parameters:

• RoHS compliance status
• Moisture sensitivity level MSL 1
• Manufacturer: Honeywell Sensing and Productivity Solutions
• Series: CPS

The substitute part must match all electrical specifications, environmental ratings, and feature set to ensure functional and mechanical compatibility within the original application circuit.

Parameter Comparison

Engineering Selection Recommendations

The Honeywell 2CPSA2A1B serves as a direct functional equivalent to the obsolete 2CPSA2A2B. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the CPS series and maintain identical electrical, environmental, and feature specifications.

Selection Basis:

The 2CPSA2A1B is the appropriate substitute because it maintains active product status while preserving all critical parameters: 4PST-2NO/2NC circuit configuration, 50mA current rating at both AC and DC, 250V AC and 60V DC voltage ratings, IP67 ingress protection, lighted indicator feature, and -40°C to 80°C operating temperature range. Both parts are RoHS compliant with MSL 1 moisture sensitivity level.

The transition from the obsolete 2CPSA2A2B to the active 2CPSA2A1B ensures continued supply chain access and long-term component availability for production and maintenance applications.
