Substitute Part Grouping Explanation

Substitution of the 2CPSA1B2B snap action switch is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: 4PST-3NC/1NO arrangement
• Current rating: 50mA (AC/DC)
• Voltage rating: 250V AC and 60V DC
• Switch function: On-Off, Off-On operation

Mechanical and Environmental Equivalence Criteria:

• Ingress protection: IP67 rating
• Operating temperature range: -40°C to 80°C
• Lighted indicator feature
• Series compatibility: CPS series

Compliance Equivalence Criteria:

• RoHS compliance status
• Moisture sensitivity level: MSL 1

The substitute part 2CPSA1B1B maintains identical electrical specifications, environmental ratings, and compliance certifications while differing only in product status (active versus obsolete) and packaging configuration (bulk versus standard).

Engineering Selection Recommendations

The 2CPSA1B1B snap action switch serves as a direct functional equivalent to the obsolete 2CPSA1B2B. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the CPS series and maintain identical electrical, mechanical, and environmental specifications.

Selection Basis:

The 2CPSA1B1B is the appropriate substitute due to:

1. Product Status: The 2CPSA1B1B maintains active product status, ensuring continued availability and manufacturer support, whereas the 2CPSA1B2B is obsolete.

2. Electrical Compliance: Both parts satisfy identical circuit requirements (4PST-3NC/1NO), current ratings (50mA AC/DC), and voltage specifications (250V AC, 60V DC).

3. Environmental Compliance: Both components meet IP67 ingress protection and operate across the identical temperature range (-40°C to 80°C).

4. Regulatory Compliance: Both parts are RoHS compliant with MSL 1 rating, meeting current environmental and moisture sensitivity standards.

5. Packaging Consideration: The 2CPSA1B1B is supplied in bulk packaging, which may require adjustment to procurement and inventory management procedures compared to the standard packaging of the 2CPSA1B2B.

Frequently Asked Questions (FAQ)

Q: Can the 2CPSA1B1B directly replace the 2CPSA1B2B in existing applications?
