Equivalent & Substitute Parts for Honeywell 1CPSC6A Snap Action Switch

Part Overview

The Honeywell 1CPSC6A is a snap action switch featuring a 4PST (4-pole, single-throw) configuration with 2NO/2NC (2 normally open, 2 normally closed) contacts. This component operates at 50mA with 250V AC and 60V DC ratings, incorporating 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 1CPSC6A carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity, maintains supply chain reliability, and supports long-term system maintenance where this component is specified in existing installations or legacy designs.

Substitute Part Grouping Explanation

Substitution of the obsolete Honeywell 1CPSC6A is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following areas:

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

Mechanical and Environmental Parameters:

• Switch function: On-Off, Off-On operation
• Ingress protection: IP67 rating for dust and water resistance
• Operating temperature: -40°C to 80°C range
• Lighted indicator feature

Compliance and Quality Parameters:

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

The substitute part 2CPSA2A1B meets all these criteria and is classified as an active product, providing ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Honeywell 2CPSA2A1B snap action switch is the direct equivalent for the obsolete 1CPSC6A. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the CPS series and maintain identical electrical, mechanical, and environmental specifications.

Product Status Advantage: The 2CPSA2A1B carries active product status, ensuring continued manufacturing support, availability, and compliance with current regulatory standards. The 1CPSC6A, classified as obsolete, presents supply chain risk and potential discontinuation of technical support.

Compliance and Certification: Both parts maintain RoHS compliance and MSL 1 moisture sensitivity rating, confirming suitability for modern manufacturing and storage environments. The identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications confirm regulatory equivalence.

Functional Equivalence: All critical parameters—circuit configuration, current and voltage ratings, ingress protection, operating temperature range, and lighted indicator feature—are identical between the two parts. Direct substitution is supported without circuit modification or system redesign.

Frequently Asked Questions (FAQ)

Q: Can the 2CPSA2A1B directly replace the 1CPSC6A in existing designs?

A: Yes. The 2CPSA2A1B is electrically and mechanically equivalent to the 1CPSC6A. All contact configurations, voltage ratings, current ratings, and environmental specifications are identical. Direct substitution is supported without circuit changes.

Q: What is the primary reason to transition from 1CPSC6A to 2CPSA2A1B?

A: The 1CPSC6A is classified as obsolete, creating supply chain risk. The 2CPSA2A1B is an active product with ongoing manufacturing support and availability, ensuring long-term component sourcing for new builds and field replacements.

Q: Are the packaging formats compatible?

A: The 1CPSC6A is supplied with standard packaging, while the 2CPSA2A1B is supplied in bulk packaging. Both formats contain identical components. Packaging selection depends on order quantity and inventory management requirements.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the 1CPSC6A and 2CPSA2A1B are RoHS compliant, carry MSL 1 moisture sensitivity rating, and maintain identical ECCN and HTSUS classifications. Environmental operating specifications—including IP67 ingress protection and -40°C to 80°C temperature range—are identical.

Q: What are the electrical specifications that define substitution eligibility?

A: Substitution is based on matching circuit configuration (4PST-2NO/2NC), current rating (50mA AC/DC), voltage ratings (250V AC, 60V DC), and switch function (On-Off, Off-On). The 2CPSA2A1B meets all these criteria.

Q: Is the lighted indicator feature present in both parts?

A: Yes. Both the 1CPSC6A and 2CPSA2A1B include a lighted indicator feature as a standard component specification.
