Substitute Part Grouping Explanation

Substitution of the CWD2425S is based on electrical and mechanical parameter equivalence within the CW24 series. The primary substitute, CWD2425P, maintains identical specifications across all critical parameters that define functional compatibility:

• Circuit configuration: SPST-NO (1 Form A)
• Input voltage range: 3–32VDC
• Load voltage range: 24–280V AC
• Load current rating: 25A
• Output type: AC with zero-cross switching
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Package type: Hockey Puck

The CWD2425P is the manufacturer-recommended equivalent and represents the active production alternative to the obsolete CWD2425S.

Parameter Comparison

Engineering Selection Recommendations

The CWD2425P is the direct functional equivalent of the CWD2425S and serves as the manufacturer-recommended substitute. Both components share identical electrical ratings and mechanical specifications, ensuring drop-in compatibility in applications currently utilizing the CWD2425S.

The CWD2425P carries active product status and is ROHS3 compliant, supporting compliance requirements for new designs and system updates. The CWD2425S, classified as obsolete, should be replaced with the CWD2425P for procurement of new inventory and long-term system reliability.

Frequently Asked Questions (FAQ)

Q: Can the CWD2425P directly replace the CWD2425S in existing applications?

A: Yes. The CWD2425P is electrically and mechanically equivalent to the CWD2425S. Both components feature identical input voltage range (3–32VDC), load voltage range (24–280V AC), load current rating (25A), circuit configuration (SPST-NO), output type (AC zero-cross), mounting type (chassis mount), termination style (screw terminal), and package type (hockey puck).

Q: What is the difference between the CWD2425S and CWD2425P?

A: The primary differences are product status and compliance certifications. The CWD2425S is obsolete, while the CWD2425P is active production. The CWD2425P is ROHS3 compliant and REACH affected, whereas the CWD2425S is REACH unaffected. Functionally, both components are equivalent.

Q: Why is the CWD2425S classified as obsolete?

A: The CWD2425S has been discontinued by Sensata Technologies. The CWD2425P is the active production model and the manufacturer-recommended replacement.

Q: Are there any package or mounting differences between these parts?

A: No. Both the CWD2425S and CWD2425P use the hockey puck package with chassis mount configuration and screw terminal termination. Physical and electrical interfaces are identical.

Q: What compliance standards apply to the CWD2425P?

A: The CWD2425P is ROHS3 compliant and REACH affected. The CWD2425S is REACH unaffected. Both components carry ECCN classification EAR99 and HTSUS code 8536.49.0080.
