Equivalent & Substitute Parts for Honeywell 1CPSC6 Snap Action Switch

Part Overview

The Honeywell 1CPSC6 is a snap action switch featuring 4PST (4-pole, single-throw) configuration with 2NO/2NC circuits, rated for 50mA at 250V AC and 60V DC. This component belongs to the CPS series 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 1CPSC6 carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1CPSC6 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must match 4PST-2NO/2NC topology
• Current Rating: Must support 50mA at both AC and DC
• Voltage Ratings: Must maintain 250V AC and 60V DC specifications
• Ingress Protection: Must provide IP67 rating
• Operating Temperature: Must cover -40°C to 80°C range
• Environmental Compliance: Must maintain RoHS compliance and MSL 1 rating

The substitute part 2CPSA1A1 satisfies all these parameters and represents a direct functional equivalent within the Honeywell CPS series.

Parameter Comparison

Engineering Selection Recommendations

The 2CPSA1A1 serves as the direct substitute for the obsolete 1CPSC6 based on complete electrical and mechanical parameter equivalence. The substitute part maintains active product status within the Honeywell CPS series, ensuring ongoing availability and manufacturing support.

Both components satisfy identical RoHS compliance requirements and MSL 1 moisture sensitivity specifications, confirming suitability for equivalent environmental and regulatory applications. The transition from 1CPSC6 to 2CPSA1A1 presents no functional or compliance compromises for applications requiring 4PST snap action switching at 50mA, 250V AC, and 60V DC ratings with IP67 environmental protection.

Frequently Asked Questions (FAQ)

Q: Can the 2CPSA1A1 directly replace the 1CPSC6 in existing designs?

A: Yes. The 2CPSA1A1 matches all electrical specifications (circuit configuration, current rating, voltage ratings), environmental protection (IP67), temperature range (-40°C to 80°C), and compliance certifications (RoHS, MSL 1) of the 1CPSC6.

Q: What is the primary difference between these parts?

A: The 1CPSC6 is obsolete, while the 2CPSA1A1 maintains active product status. Both are manufactured by Honeywell within the CPS series and share identical functional parameters.

Q: Are there packaging differences between 1CPSC6 and 2CPSA1A1?

A: The 1CPSC6 is listed with dash packaging notation, while the 2CPSA1A1 is supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Does the 2CPSA1A1 support the same voltage and current specifications?

A: Yes. Both parts are rated for 50mA at 250V AC and 60V DC with identical 4PST-2NO/2NC circuit configuration.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1CPSC6 and 2CPSA1A1 carry RoHS compliance certification and MSL 1 moisture sensitivity rating.
