Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2CPSA1A2A-FW is determined by strict equivalence across the following critical parameters:

Circuit Architecture: Both the main part and substitute must maintain identical 4PST-2NO/2NC configuration to ensure pin compatibility and functional equivalence in control circuits.

Electrical Ratings: Current rating of 50mA (AC/DC), AC voltage rating of 250V, and DC voltage rating of 60V must be matched exactly. These parameters define the component's load-handling capability and system integration requirements.

Environmental Specifications: IP67 ingress protection rating and operating temperature range of -40°C to 80°C must be preserved to maintain performance in specified deployment environments.

Regulatory Compliance: RoHS compliance status and MSL 1 classification must be maintained for supply chain and manufacturing process compatibility.

Manufacturer Consistency: Parts must originate from Honeywell Sensing and Productivity Solutions within the CPS series to ensure design validation and quality assurance alignment.

The 2CPSA1A2B qualifies as a direct substitute based on complete parameter alignment across all specified criteria.
