CD4850E4V Equivalent & Substitute Parts

Part Overview

The CD4850E4V is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a SPST-NO (Single Pole Single Throw - Normally Open) dual-channel device in a hockey puck package. This component is rated for 50A load current with input voltage range of 15–32VDC and output voltage range of 48–660VAC, featuring zero-cross switching for AC loads. The CD4850E4V is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs requiring this functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4850E4V is determined by the following critical parameters:

• Circuit Configuration: SPST-NO (1 Form A) x 2 dual-channel topology
• Load Current Rating: 50A minimum
• Output Voltage Range: 48–660VAC capability
• Output Type: AC with zero-cross switching
• Package Form Factor: Hockey puck mechanical envelope
• Termination: Screw terminal interface
• Mounting: Chassis mount orientation

Substitute parts must maintain identical or compatible electrical specifications across these parameters. Input voltage range variations are permissible provided the substitute accommodates the control signal voltage of the application.

Engineering Selection Recommendations

CD4850E3V is the manufacturer-recommended substitute. This part maintains identical input voltage range (15–32VDC) and all critical electrical parameters as the CD4850E4V. The CD4850E3V is in active production status with RoHS compliance certification, ensuring long-term availability and regulatory alignment.

CC4850W4V and CD4850W4V are direct functional equivalents with expanded input voltage range (4–32VDC), providing greater flexibility for lower-voltage control circuits. Both parts are active production items with RoHS compliance. The expanded input voltage range does not compromise compatibility with 15–32VDC control signals. CC4850W4V and CD4850W4V differ only in base product designation (CC4850 vs. CD4850) and are functionally interchangeable for this application.

All three substitute parts are manufactured by Sensata Technologies or Sensata-Crydom, maintaining the Evolution Dual series lineage and ensuring mechanical and electrical compatibility with the obsolete CD4850E4V.

Frequently Asked Questions (FAQ)

Q: Can CC4850W4V or CD4850W4V be used as direct replacements for CD4850E4V?

A: Yes. Both parts maintain the same load current rating (50A), output voltage range (48–660VAC), circuit configuration (SPST-NO x 2), package form factor (hockey puck), and termination style (screw terminal). The expanded input voltage range (4–32VDC vs. 15–32VDC) does not affect compatibility with standard 15–32VDC control signals.

Q: What is the difference between CC4850W4V and CD4850W4V?

A: Both parts are electrically and mechanically identical. The difference is in the base product number designation (CC4850 vs. CD4850). Selection between these two should be based on inventory availability and supplier preference, as they are functionally interchangeable.

Q: Is CD4850E3V preferred over the W-series substitutes?

A: CD4850E3V is the manufacturer-recommended substitute and maintains the exact input voltage range of the obsolete CD4850E4V. If the application control circuit operates strictly within 15–32VDC, CD4850E3V is the optimal choice. The W-series parts (CC4850W4V, CD4850W4V) are suitable alternatives if lower input voltage capability (down to 4VDC) is beneficial or if inventory constraints favor their selection.

Q: Are all substitute parts RoHS compliant?

A: Yes. CC4850W4V, CD4850W4V, and CD4850E3V are all RoHS compliant. The obsolete CD4850E4V RoHS status was not specified in available documentation.

Q: Does the hockey puck package ensure mechanical compatibility?

A: Yes. All substitute parts use the identical hockey puck package form factor with chassis mount orientation and screw terminal termination, ensuring direct mechanical compatibility with existing mounting hardware and wiring infrastructure designed for the CD4850E4V.
