CC4850W4U Equivalent & Substitute Parts

Part Overview

The CC4850W4U is a solid-state relay (SSR) manufactured by Sensata-Crydom, classified as a SPST-NO (Single Pole Single Throw - Normally Open) configuration with dual 1 Form A circuits. This active product is designed for chassis mount applications with screw terminal connections and operates with AC zero-cross output switching. The device handles 50A load current across a 48V to 660V operating range with 4-32VDC input control voltage. Finding equivalent or substitute parts may be necessary due to supply constraints, lead time requirements, or specific application compatibility needs while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CC4850W4U is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO (1 Form A) x 2 to maintain functional equivalence
• Load Current Rating: Must be rated for 50 A minimum
• Output Type: Must support AC with zero-cross switching capability
• Mounting Type: Must be chassis mount compatible
• Termination Style: Must use screw terminal connections
• Product Status: Must be active to ensure ongoing availability and support

The substitute part ASR-SID480D50ZL-S meets the core functional requirements of circuit configuration, load current rating, output type, mounting type, and termination style. However, differences exist in load voltage range and input voltage specifications that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the CC4850W4U and ASR-SID480D50ZL-S are active products with current manufacturing status and full RoHS compliance certifications. The CC4850W4U maintains a broader operational envelope with load voltage capability up to 660V and input voltage tolerance to 32VDC. The ASR-SID480D50ZL-S operates within a narrower specification window with maximum load voltage of 530V and input voltage limited to 15VDC. Selection between these parts depends on whether the application load voltage and control input voltage requirements fall within the ASR-SID480D50ZL-S operating range. Both devices share identical load current capacity, circuit topology, output switching characteristics, and termination methodology. Package form factor differs between Hockey Puck and Module configurations, which may affect mechanical integration considerations.

Frequently Asked Questions (FAQ)

Q: Can the ASR-SID480D50ZL-S replace the CC4850W4U in all applications?

A: Substitution is valid only when the application load voltage remains between 24V and 530V and the control input voltage does not exceed 15VDC. Applications requiring load voltages above 530V or input voltages above 15VDC must use the CC4850W4U.

Q: What are the key functional similarities between these parts?

A: Both devices provide identical 50A load current capacity, dual SPST-NO circuit configuration, AC zero-cross output switching, chassis mount design, and screw terminal connections. Both are active products with current RoHS compliance.

Q: How do the package types differ?

A: The CC4850W4U uses a Hockey Puck package form factor, while the ASR-SID480D50ZL-S uses a Module package type. These differences may affect mechanical mounting and spatial integration within the application enclosure.

Q: Are both parts RoHS compliant?

A: Yes. The CC4850W4U is RoHS Compliant, and the ASR-SID480D50ZL-S is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions.

Q: What voltage parameters must be verified before substitution?

A: Verify that the application load voltage operates within 24V to 530V range and that the control input voltage does not exceed 15VDC. If either parameter exceeds these limits, the CC4850W4U is required.
