CMD2425-10 Solid State Relay SPST-NO 25A 24-280V Equivalent & Substitute Parts

Part Overview

The CMD2425-10 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 3–32VDC and output voltage range of 24–280VAC. This hockey puck-style relay is designed for chassis mount applications with screw terminal connections. The part is currently active in production with 854 units in stock and carries RoHS compliance certification.

Equivalent and substitute parts are identified when they maintain identical electrical specifications, mechanical form factor, and termination style while potentially offering alternative sourcing options or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMD2425-10 is determined by strict equivalence across the following critical parameters:

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

The identified substitute parts (84137210 and CWD2425-10) satisfy all of these requirements. Variations in RoHS certification level, REACH status, MSL rating, and HTSUS classification do not affect functional interchangeability for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CMD2425-10, 84137210, and CWD2425-10—are functionally equivalent and interchangeable for applications requiring a 25A SPST-NO solid state relay with the specified voltage and current ratings.

Selection between these parts may be based on:

• Availability: CMD2425-10 (854 units) and CWD2425-10 (822 units) offer higher stock levels than 84137210 (689 units).
• Compliance requirements: Both 84137210 and CWD2425-10 carry ROHS3 certification, while CMD2425-10 carries RoHS compliance. REACH status is documented for 84137210 and CWD2425-10.
• Supply chain continuity: Multiple manufacturers and series options (CMD24, GN, CW24) provide sourcing flexibility.

All parts are active products with no known end-of-life status.

Frequently Asked Questions (FAQ)

Q: Can CMD2425-10 be directly replaced with 84137210 or CWD2425-10?

A: Yes. All three parts share identical electrical specifications (25A, 3–32VDC input, 24–280VAC output), circuit configuration (SPST-NO), mounting type (Chassis Mount), package style (Hockey Puck), and termination style (Screw Terminal). Direct substitution is supported without circuit modification.

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

A: ROHS3 represents a more recent iteration of RoHS certification with updated substance restrictions. Both certifications indicate compliance with hazardous substance limitations. The presence of ROHS3 on 84137210 and CWD2425-10 does not affect functional compatibility with CMD2425-10.

Q: Does MSL (Moisture Sensitivity Level) rating affect substitution?

A: MSL rating applies to storage and handling conditions for moisture-sensitive components. CMD2425-10 is rated "Not Applicable," while 84137210 is rated MSL 1 (Unlimited). This difference does not affect electrical or mechanical interchangeability and does not restrict substitution.

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 electrical connection methods are identical.

Q: What does REACH status mean for part selection?

A: REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) is a European Union chemical safety regulation. 84137210 and CWD2425-10 are documented as REACH Affected. This designation does not affect functional performance and does not restrict substitution for applications within compliant regulatory frameworks.
