Equivalent & Substitute Parts for Honeywell 1CPSA2-N Snap Action Switch

Part Overview

The Honeywell 1CPSA2-N is a snap action switch featuring 4PST (4-pole, single-throw) configuration with 2NO/2NC circuits, rated for 10A at 600V AC and 250V DC. This component belongs to the CPS series of industrial switching devices and provides IP67-rated environmental protection suitable for dust-tight and waterproof applications across an operating temperature range of -40°C to 80°C.

The 1CPSA2-N carries an Obsolete product status. Locating functionally equivalent alternatives is necessary to ensure design continuity, maintain supply chain reliability, and support long-term system maintenance where original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1CPSA2-N is determined by strict equivalence across the following critical parameters:

Circuit Configuration: The substitute must maintain identical 4PST-2NO/2NC pole and throw arrangement to ensure compatible wiring and control logic integration.

Electrical Ratings: Current rating of 10A (AC/DC), AC voltage rating of 600V, and DC voltage rating of 250V must be matched or exceeded without modification to the application circuit.

Environmental Protection: IP67 ingress protection rating is mandatory for applications requiring dust-tight and waterproof operation.

Operating Temperature Range: The -40°C to 80°C specification must be maintained to ensure reliable operation across the intended thermal envelope.

Switch Function: On-Off, Off-On functionality must be preserved to maintain control behavior consistency.

The substitute part 1CPSA2 satisfies all these criteria while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 1CPSA2 is the direct functional equivalent of the 1CPSA2-N and serves as the primary substitute for this obsolete component. Both parts are manufactured by Honeywell Sensing and Productivity Solutions within the CPS series and maintain identical electrical and environmental specifications.

The 1CPSA2 offers two significant advantages over the 1CPSA2-N:

Product Status: The 1CPSA2 maintains Active product status, ensuring continued availability and manufacturer support. The 1CPSA2-N is classified as Obsolete, indicating discontinued production and limited future supply.

Regulatory Compliance: The 1CPSA2 is RoHS Compliant, whereas the 1CPSA2-N is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the 1CPSA2 provides superior regulatory alignment.

Both parts carry identical ECCN classification (EAR99) and MSL rating (1 - Unlimited), indicating equivalent export control and moisture handling characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 1CPSA2 directly replace the 1CPSA2-N in existing applications?

A: Yes. The 1CPSA2 maintains identical circuit configuration (4PST-2NO/2NC), electrical ratings (10A at 600V AC / 250V DC), environmental protection (IP67), and operating temperature range (-40°C to 80°C). No circuit modifications or application redesign is required.

Q: What is the difference between the 1CPSA2-N and 1CPSA2?

A: The primary differences are product status and RoHS compliance. The 1CPSA2-N is Obsolete and RoHS non-compliant, while the 1CPSA2 is Active and RoHS Compliant. All functional and electrical parameters are identical.

Q: Does packaging differ between these parts?

A: The 1CPSA2-N is supplied with unspecified packaging ("-"), while the 1CPSA2 is supplied in Bulk packaging. Verify packaging requirements with your procurement specification before ordering.

Q: Are there inventory considerations when switching to the 1CPSA2?

A: Current inventory shows 964 units of the 1CPSA2 available as New Original In Stock, compared to 850 units of the 1CPSA2-N. The 1CPSA2's Active status provides better long-term supply assurance.

Q: What is the base product number for these parts?

A: The base product number is 1CPSA. Both the 1CPSA2-N and 1CPSA2 are variants within this product family.

Q: Are export controls identical for both parts?

A: Yes. Both parts carry ECCN classification EAR99, indicating identical export control treatment.
