CD2425E1U Equivalent & Substitute Parts

Part Overview

The CD2425E1U is a Sensata-Crydom Evolution Dual series solid state relay (SSR) with SPST-NO (1 Form A) x 2 configuration in Hockey Puck package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The CD2425E1U operates with 15–32VDC input, handles 24–280V AC loads at 25A, and features zero-cross switching for AC applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD2425E1U is determined by strict electrical and mechanical compatibility across the following parameters:

• Circuit configuration: SPST-NO (1 Form A) x 2
• Output type: AC, Zero Cross
• Load voltage range: 24 V ~ 280 V
• Load current: 25 A
• Mounting type: Chassis Mount
• Package type: Hockey Puck
• Termination style: Screw Terminal

The primary distinction among substitute parts is the input voltage range. The CD2425E1U accepts 15–32VDC input. Substitute parts may accept either 15–32VDC or 4–32VDC input ranges. A 4–32VDC input range provides broader input compatibility and represents a functional superset of the original specification.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CC2425W1U, CD2425E3U, and CD2425W3U—maintain full electrical and mechanical compatibility with the CD2425E1U across load specifications, circuit configuration, and physical form factor.

CC2425W1U and CD2425W3U both feature 4–32VDC input voltage range, which encompasses the original 15–32VDC specification and provides extended low-voltage operation capability. CD2425E3U maintains the original 15–32VDC input range.

All substitute parts carry Active product status, ensuring long-term availability and supply chain continuity. CC2425W1U, CD2425E3U, and CD2425W3U are all RoHS Compliant, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CC2425W1U replace CD2425E1U directly?

A: Yes. CC2425W1U is electrically and mechanically compatible. It features identical load specifications (25A, 24–280V AC), circuit configuration (SPST-NO x 2), and package type (Hockey Puck). The input voltage range of 4–32VDC is a functional superset of the original 15–32VDC specification.

Q: What is the difference between CD2425E3U and CD2425W3U?

A: Both parts are identical except for input voltage range. CD2425E3U accepts 15–32VDC input, matching the original CD2425E1U specification. CD2425W3U accepts 4–32VDC input, providing extended low-voltage capability.

Q: Are all substitute parts RoHS Compliant?

A: Yes. CC2425W1U, CD2425E3U, and CD2425W3U are all RoHS Compliant. The original CD2425E1U RoHS status was not specified in available documentation.

Q: Does input voltage range affect load switching performance?

A: No. Input voltage range does not affect AC load switching characteristics, zero-cross operation, or current capacity. All substitute parts deliver identical load-side performance at 25A and 24–280V AC.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the design input voltage supply falls within the substitute part's input range. For designs operating above 32VDC or below 4VDC, verify the specific substitute part's input specification before selection.
