CD4850W4V Solid State Relay SPST-NO 50A 48-660V Equivalent & Substitute Parts

Part Overview

The CD4850W4V is a solid state relay (SSR) manufactured by Sensata Technologies, classified as a SPST-NO (Single Pole Single Throw - Normally Open) configuration with dual Form A circuits. This active product is designed for AC load switching applications with zero-cross detection, operating from 4-32VDC input control voltage and supporting load voltages from 48V to 660V at 50A capacity. The Hockey Puck package format and screw terminal termination make it suitable for chassis-mounted industrial control applications. Equivalent and substitute parts are identified based on matching electrical specifications, circuit configuration, and mechanical compatibility within the SSR relay category.

Substitute Part Grouping Explanation

Substitute parts for the CD4850W4V are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Circuit configuration: SPST-NO (1 Form A) x 2
Output type: AC with zero-cross detection
Load current rating: 50 A
Termination style: Screw Terminal
Load voltage range: Minimum 48V to maximum 660V capability
Input voltage range: Minimum 4VDC to maximum 32VDC capability

Secondary Compatibility Factors:

Mounting type: Chassis Mount (primary) or Chassis Mount with Panel Mount options
Package format: Hockey Puck or Module configurations
RoHS compliance status
Product status: Active

Two substitute parts meet the core electrical specifications with noted parameter variations:

84140603N (Crouzet GN2 Series): Matches all primary electrical criteria with identical input/output voltage ranges and load current. Package format differs (Module vs. Hockey Puck) but maintains screw terminal termination and chassis mount capability.

ASR-SID480D50ZL-S (Altran Magnetics SID Series): Meets circuit configuration and load current requirements but operates within reduced voltage ranges (4-15VDC input, 24-530V load) compared to the CD4850W4V specification envelope.

Engineering Selection Recommendations

84140603N (Crouzet GN2 Series): This substitute provides full electrical equivalence to the CD4850W4V across all specified voltage and current parameters. The primary difference is the Module package format versus Hockey Puck, which may require mechanical redesign of mounting interfaces. Both parts maintain active product status and RoHS compliance. The Crouzet part offers additional mounting flexibility with panel mount capability. Selection of this substitute is appropriate when mechanical package accommodation can be addressed in the application design.

ASR-SID480D50ZL-S (Altran Magnetics SID Series): This substitute matches the circuit configuration and load current rating but operates within a reduced voltage envelope. The input voltage range is limited to 4-15VDC (versus 4-32VDC), and the load voltage range is 24-530V (versus 48-660V). This part is suitable only for applications where the actual operating voltages fall within these narrower specifications. Both parts maintain active status and ROHS3 compliance. Selection requires verification that application voltage requirements do not exceed the specified limits.

Frequently Asked Questions (FAQ)

Q: Can the 84140603N replace the CD4850W4V in any application?

A: The 84140603N provides electrical equivalence across all voltage and current specifications. The primary consideration is mechanical compatibility. The Module package format differs from the Hockey Puck format of the CD4850W4V, requiring evaluation of mounting interface requirements in your specific application.

Q: What are the voltage limitations of the ASR-SID480D50ZL-S substitute?

A: The ASR-SID480D50ZL-S operates with input voltage range of 4-15VDC and load voltage range of 24-530V. These ranges are narrower than the CD4850W4V specification of 4-32VDC input and 48-660V load. This substitute is compatible only with applications operating within these voltage limits.

Q: Are all three parts RoHS compliant?

A: Yes. The CD4850W4V is RoHS Compliant. Both substitute parts (84140603N and ASR-SID480D50ZL-S) are ROHS3 Compliant, representing the current RoHS standard.

Q: What is the difference between Hockey Puck and Module package formats?

A: Both are solid state relay package formats with screw terminal termination. The Hockey Puck format (CD4850W4V) and Module format (84140603N, ASR-SID480D50ZL-S) differ in physical dimensions and mounting interface design. Selection depends on available space and mounting infrastructure in your application.

Q: Can I use the ASR-SID480D50ZL-S if my application requires 660V load voltage?

A: No. The ASR-SID480D50ZL-S maximum load voltage is 530V. Applications requiring 660V load voltage capability must use either the CD4850W4V or the 84140603N.

Q: Are all parts available in active production status?

A: Yes. The CD4850W4V, 84140603N, and ASR-SID480D50ZL-S are all classified as Active products, indicating current manufacturing and availability.
