CSD2425-10 Equivalent & Substitute Parts

Part Overview

The CSD2425-10 is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a single-pole single-throw normally open (SPST-NO) device rated for 25A load current with input voltage range of 4.6–15VDC and output voltage range of 24–280VAC. The part is housed in a hockey puck package with screw terminal connections and is currently classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality and ensure continued availability for replacement and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSD2425-10 is determined by the following critical parameters:

• Circuit configuration must remain SPST-NO (1 Form A)
• Output type must be AC
• Load current rating must be 25A
• Load voltage range must encompass 24–280VAC
• Mounting type must be chassis mount
• Termination style must be screw terminal
• Package type must be hockey puck
• Moisture sensitivity level must be 1 (Unlimited)

The substitute parts identified below meet all these criteria. Variations in input voltage range and product status are noted but do not preclude substitution when the above parameters align.

Parameter Comparison

Engineering Selection Recommendations

CSW2425-10 (Sensata Technologies): This part is a direct substitute from the same manufacturer family. It maintains identical load specifications and package configuration. The expanded input voltage range (3–32VDC versus 4.6–15VDC) provides greater flexibility for control circuit designs. However, the part carries Last Time Buy status, indicating limited future availability. ROHS3 compliance and REACH Affected designation should be evaluated against system requirements.

84137210N (Crouzet): This part is an active product with full manufacturer support and availability. It meets all critical electrical and mechanical parameters. The input voltage range (4–32VDC) is broader than the original part. RoHS compliance and REACH Unaffected status may be advantageous for applications with strict environmental or regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can CSW2425-10 be used as a direct replacement for CSD2425-10?

A: Yes. Both parts share identical circuit configuration, load ratings, voltage ranges, and package type. The CSW2425-10 input voltage range is broader, which is compatible with the original design envelope.

Q: What is the difference between Last Time Buy and Active product status?

A: Last Time Buy indicates the manufacturer will cease production after a specified date. Active status means the part remains in current production. For long-term supply chain planning, the 84137210N (Active) may be preferable to CSW2425-10 (Last Time Buy).

Q: Are there differences in input voltage handling between the substitutes?

A: Yes. CSD2425-10 accepts 4.6–15VDC, CSW2425-10 accepts 3–32VDC, and 84137210N accepts 4–32VDC. All three ranges are compatible with standard 5VDC and 12VDC control circuits. Designs operating at the extremes of the original range should verify compatibility with the substitute's input specification.

Q: Does RoHS or REACH compliance affect substitution?

A: RoHS and REACH compliance are regulatory designations that may be required depending on application and market. CSW2425-10 is ROHS3 Compliant and REACH Affected. 84137210N is RoHS Compliant and REACH Unaffected. Verify compliance requirements against your system specifications before selection.

Q: Are all three parts mechanically interchangeable?

A: Yes. All three parts are chassis-mount hockey puck packages with screw terminal connections, ensuring mechanical and electrical interface compatibility.
