CWD4810 Equivalent & Substitute Parts

Part Overview

The CWD4810 is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a single-pole single-throw normally open (SPST-NO) device rated for 10A load current with input voltage range of 4–32VDC and load voltage range of 48–660V. The device features zero-cross switching for AC loads and is housed in a hockey puck package with screw terminal connections. This part is currently active in production and maintains full ROHS3 compliance and REACH affected status. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWD4810 is determined by matching the following critical parameters: circuit configuration (SPST-NO), output type (AC with zero-cross switching), input voltage range (4–32VDC), load current rating (10A), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck).

The substitute parts identified—84134100 (Sensata Technologies) and 84137000N (Crouzet)—share identical circuit configuration, output type, input voltage range, load current rating, mounting type, termination style, and package type. However, the load voltage range differs between substitutes: 84134100 maintains the full 48–660V range, while 84137000N operates within a reduced range of 24–280V. This voltage range limitation must be evaluated against application requirements before selection.

Parameter Comparison

Engineering Selection Recommendations

84134100 (Sensata Technologies): This part is a direct functional equivalent to the CWD4810. It maintains identical electrical specifications including the full 48–660V load voltage range, input voltage range, and 10A current rating. Both parts carry ROHS3 compliance and REACH affected status. The 84134100 is supplied in bulk packaging and represents the primary equivalent for applications requiring the extended voltage range of the original CWD4810.

84137000N (Crouzet): This part shares the same circuit configuration, input voltage range, load current rating, and package form factor as the CWD4810. However, the load voltage range is limited to 24–280V, which is a significant restriction compared to the original 48–660V specification. The 84137000N carries RoHS compliance (not ROHS3) and is REACH unaffected. This part is suitable only for applications operating within the 24–280V load voltage window. It is supplied in box packaging rather than bulk format.

Frequently Asked Questions (FAQ)

Q: Can 84134100 be used as a direct replacement for CWD4810? A: Yes. The 84134100 maintains identical electrical specifications, circuit configuration, input voltage range, load current rating, mounting type, termination style, and package form factor. Both parts are ROHS3 compliant and REACH affected.

Q: What is the primary limitation of 84137000N as a substitute? A: The 84137000N operates with a reduced load voltage range of 24–280V compared to the CWD4810's 48–660V range. Applications requiring load voltages above 280V or below 24V cannot use this substitute. All other electrical and mechanical parameters are compatible.

Q: Are there differences in compliance certifications between these parts? A: The CWD4810 and 84134100 both carry ROHS3 compliance and REACH affected status. The 84137000N carries RoHS compliance (not ROHS3) and is REACH unaffected. Applications subject to ROHS3 or REACH requirements should verify compliance obligations before selecting 84137000N.

Q: Does packaging format affect substitution eligibility? A: Packaging format (bulk versus box) does not affect electrical or mechanical compatibility. The CWD4810 and 84134100 are supplied in bulk; 84137000N is supplied in box format. Selection should be based on procurement and inventory requirements.

Q: What parameters must match for a part to be considered a substitute? A: Critical matching parameters include circuit configuration (SPST-NO), output type (AC with zero-cross switching), input voltage range (4–32VDC), load current rating (10A), mounting type (chassis mount), termination style (screw terminal), and package form factor (hockey puck). Load voltage range must be evaluated against application requirements.
