D4850-10 Equivalent & Substitute Parts

Part Overview

The D4850-10 is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (1 Form A) device in a hockey puck package. This component is designed for AC load switching applications with a 50A capacity and operates with input control voltages between 3 and 32VDC. The device is currently in active production status and is RoHS compliant.

Equivalent and substitute parts are identified when alternative components meet or exceed the electrical and mechanical specifications of the original part, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

The D4850-10 has one identified substitute: the Crouzet 84137320N. Substitution eligibility is determined by the following critical parameters:

• Circuit Configuration: Both parts must be SPST-NO (1 Form A) to maintain identical switching logic
• Output Type: Both must be AC-rated for compatible load applications
• Load Current: The substitute must support the required 50A capacity
• Package Type: Both must use the hockey puck form factor for mechanical compatibility
• Mounting Type: Both must support chassis mount installation
• Termination Style: Both must use screw terminals for connection compatibility
• Input Voltage Range: The substitute input range must encompass or exceed the original specification
• Load Voltage Range: The substitute load voltage range must encompass or exceed the original specification
• Compliance: Both must maintain RoHS compliance status

Parameter Comparison

Engineering Selection Recommendations

Both the D4850-10 and 84137320N are active production components with RoHS compliance certification. The Crouzet 84137320N provides an extended load voltage range (48 ~ 660V versus 80 ~ 530V) and a marginally higher minimum input voltage threshold (4VDC versus 3VDC). These differences do not restrict substitution in applications where the original D4850-10 specification is met. Selection between these parts should be based on component availability, lead time requirements, and procurement cost considerations.

Frequently Asked Questions (FAQ)

Q: Can the Crouzet 84137320N replace the D4850-10 in all applications?

A: Yes, provided the application operates within the D4850-10 specification envelope. The Crouzet part meets or exceeds all critical electrical and mechanical parameters. The extended load voltage range of the Crouzet part does not create incompatibility.

Q: What is the significance of the different input voltage minimums (3VDC vs. 4VDC)?

A: The D4850-10 operates from 3VDC minimum, while the 84137320N operates from 4VDC minimum. If your application requires control signals below 4VDC, the D4850-10 is the appropriate choice. For applications operating at 4VDC and above, both parts are functionally equivalent.

Q: Are the hockey puck packages mechanically identical?

A: Both parts use the hockey puck form factor with chassis mount configuration and screw terminal termination. Mechanical compatibility is confirmed for direct substitution in existing installations.

Q: Do both parts carry the same compliance certifications?

A: Both the D4850-10 and 84137320N are RoHS compliant. The Crouzet part carries additional REACH Unaffected status. Both are classified under ECCN EAR99.

Q: What is the difference in load voltage capability?

A: The D4850-10 supports 80 ~ 530V AC loads, while the 84137320N supports 48 ~ 660V AC loads. The Crouzet part extends the lower and upper voltage boundaries, providing broader application coverage without restricting the original specification range.
