CMD2425 Solid State Relay SPST-NO 25A 24-280V

Part Overview

The CMD2425 is a solid state relay (SSR) manufactured by Sensata-Crydom, configured as a single-pole single-throw normally open (SPST-NO) device with a 25A load capacity and 24V to 280V output voltage range. This hockey puck-style relay operates with DC input control (3V to 32VDC) and features zero-cross AC output switching. The part is currently active in production with 757 units in stock.

Equivalent and substitute parts are identified when they maintain identical electrical performance parameters and mechanical compatibility within the CMD24 and related series families. Substitution becomes necessary when the primary part number is unavailable or when design flexibility across compatible series is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMD2425 is determined by strict equivalence across the following critical parameters:

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

The identified substitutes (84137010 and CWD2425) meet all electrical and mechanical requirements. Differences in series designation (GN and CW24 respectively), RoHS certification level, and REACH compliance status do not affect functional interchangeability within applications requiring these core parameters.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (CMD2425, 84137010, and CWD2425) are active products from Sensata-Crydom with identical electrical and mechanical specifications. Selection between them should be based on:

Compliance Requirements: The CMD2425 carries RoHS Compliance status. Both 84137010 and CWD2425 meet ROHS3 Compliance, which represents a more recent regulatory standard. Applications requiring REACH compliance should specify either 84137010 or CWD2425, as both are REACH Affected.

Inventory Availability: CMD2425 has 757 units in stock, 84137010 has 1351 units, and CWD2425 has 1001 units. Selection may be influenced by supply chain requirements and lead time considerations.

Series Compatibility: The CMD2425 belongs to the CMD24 series, 84137010 to the GN series, and CWD2425 to the CW24 series. Series designation does not affect functional performance but may be relevant for documentation and traceability purposes.

Frequently Asked Questions (FAQ)

Q: Can CMD2425 be directly replaced with 84137010 or CWD2425 in existing designs?

A: Yes. All three parts share identical electrical parameters (25A load current, 3-32VDC input, 24-280V output, SPST-NO configuration, AC zero-cross switching) and mechanical specifications (hockey puck package, screw terminals, chassis mount). Direct substitution is electrically and mechanically valid.

Q: What is the difference between RoHS Compliance and ROHS3 Compliance?

A: ROHS3 Compliance represents a more recent regulatory iteration. Both certifications indicate compliance with hazardous substance restrictions. Selection between them depends on application regulatory requirements and customer specifications.

Q: Does the series designation (CMD24, GN, CW24) affect interchangeability?

A: No. Series designation is a manufacturer classification system. It does not affect electrical performance, load capacity, voltage ratings, or mechanical fit. All three parts are functionally equivalent within applications requiring the specified parameters.

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

A: No. All three parts use screw terminal connections and chassis mount configuration. Physical installation and wiring procedures are identical.

Q: Which part should be selected for new designs?

A: Selection should be based on compliance requirements (REACH status if applicable), inventory availability, and internal design documentation standards. From a purely technical standpoint, all three parts are equivalent.
