Equivalent & Substitute Parts for Honeywell 1CPSA4B-N

Part Overview

The Honeywell 1CPSA4B-N is a snap-action switch with 4PST-NC (four-pole, single-throw, normally closed) configuration rated for 10A at 600V AC and 250V DC. This switch features a lighted indicator and IP67 ingress protection rating, making it suitable for industrial control applications requiring sealed, waterproof operation across extended temperature ranges.

The 1CPSA4B-N is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure availability for replacement, repair, and new production applications where this switch type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1CPSA4B-N are identified based on strict electrical and mechanical parameter matching within the Honeywell CPS series. The substitution logic is based on the following criteria:

Primary Matching Parameters:

• Circuit configuration (4PST-NC)
• Current rating (10A AC/DC)
• Voltage ratings (600V AC / 250V DC)
• Ingress protection (IP67)
• Operating temperature range (-40°C to 80°C)
• Switch function (On-Off)
• RoHS compliance status

Substitution Basis: Parts are grouped as equivalent when all primary electrical parameters are identical. The 1CPSC4 is classified as a substitute because it maintains identical circuit topology, current capacity, voltage ratings, ingress protection, temperature range, and regulatory compliance. Differences in product status (active vs. obsolete) and feature set (lighted indicator presence) do not affect electrical or mechanical interchangeability for the core switching function.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The 1CPSC4 is electrically and mechanically equivalent to the 1CPSA4B-N for all core switching functions. Both parts maintain identical electrical specifications, environmental ratings, and regulatory compliance. The 1CPSC4 is the preferred selection for new designs and ongoing production due to its active product status, ensuring long-term availability and supply chain continuity.

Consideration of Product Status:

The 1CPSA4B-N is classified as obsolete, indicating that Honeywell has discontinued active manufacturing and support. The 1CPSC4, classified as active, represents the current production equivalent within the CPS series and is the recommended substitute for all applications where the 1CPSA4B-N was previously specified.

Regulatory and Compliance Alignment:

Both parts are RoHS compliant and carry identical ECCN classification (EAR99), ensuring compatibility with export control and environmental regulations. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part.

Feature Differentiation:

The 1CPSA4B-N includes a lighted indicator feature not specified for the 1CPSC4. If the lighted indicator is a functional requirement for the application, this difference must be evaluated against the core switching specifications before substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1CPSC4 be used as a direct replacement for the 1CPSA4B-N in existing installations?

A: Yes. The 1CPSC4 is electrically and mechanically equivalent. Both parts share identical circuit configuration (4PST-NC), current rating (10A AC/DC), voltage ratings (600V AC / 250V DC), ingress protection (IP67), and operating temperature range (-40°C to 80°C). The primary difference is product status: the 1CPSA4B-N is obsolete while the 1CPSC4 is active.

Q: What is the significance of the lighted indicator feature on the 1CPSA4B-N?

A: The lighted indicator is a visual feedback feature present on the 1CPSA4B-N but not specified for the 1CPSC4. If the application requires visual indication of switch state, this functional difference must be addressed separately. The core switching function remains identical between both parts.

Q: Are there any packaging or mechanical differences between these parts?

A: Packaging information is not provided in the technical specifications for either part. Mechanical compatibility should be verified through dimensional drawings and mounting specifications from Honeywell documentation.

Q: Why is the 1CPSC4 recommended over the 1CPSA4B-N?

A: The 1CPSC4 is classified as an active product, ensuring ongoing manufacturing support, availability, and supply chain reliability. The 1CPSA4B-N is obsolete, meaning Honeywell has discontinued production. For new designs and long-term applications, the active 1CPSC4 is the appropriate selection.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 1CPSA4B-N and 1CPSC4 are RoHS compliant, carry identical ECCN classification (EAR99), and have MSL rating of 1 (Unlimited). They are equivalent from a regulatory and environmental compliance perspective.

Q: What parameters must match exactly for substitution to be valid?

A: The following parameters must be identical: circuit configuration (4PST-NC), current rating (10A AC/DC), voltage ratings (600V AC / 250V DC), ingress protection (IP67), operating temperature range (-40°C to 80°C), and switch function (On-Off). These parameters define the electrical and environmental performance envelope of the switch.
