CEDS0524V-G Equivalent & Substitute Parts

Part Overview

The CEDS0524V-G is a 24V Transient Voltage Suppressor (TVS) diode manufactured by Comchip Technology, designed for general-purpose transient protection applications. This component features a 25V clamp voltage, 15A peak pulse current (8/20µs), and operates across the temperature range of -55°C to 125°C. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the CEDS0524V-G is determined by the following critical parameters:

• Bidirectional Channels: Must equal 4 channels for equivalent protection topology
• Package Type: Must be SOT-23-5 or compatible surface-mount package for PCB layout compatibility
• Mounting Type: Must be surface mount to maintain assembly process compatibility
• Category: Must be Transient Voltage Suppressors (TVS) with Zener type classification
• Applications: General-purpose transient protection capability

The substitute part NUP4004M5T1G meets the core structural requirements (4-channel bidirectional TVS, SOT-23-5 package, surface mount) and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The NUP4004M5T1G is an active product with current manufacturing support from onsemi, providing supply chain continuity for the obsolete CEDS0524V-G. Both components share identical structural characteristics: 4-channel bidirectional TVS topology, SOT-23-5 package family, and surface-mount configuration.

Selection of NUP4004M5T1G is supported by:

• Active product status ensuring long-term availability and manufacturing consistency
• RoHS3 compliance for regulatory alignment with modern procurement standards
• REACH unaffected status matching the original component
• Identical EAR99 ECCN classification
• General-purpose TVS application category alignment

The substitute part operates within a reduced temperature range (-40°C to 125°C junction temperature versus -55°C to 125°C ambient for the original) and carries MSL-3 moisture sensitivity versus MSL-1 for the original component. These differences require evaluation against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can NUP4004M5T1G directly replace CEDS0524V-G in existing designs?

A: Both components share the same 4-channel bidirectional TVS topology and SOT-23-5 package family. Functional compatibility depends on application voltage requirements. The CEDS0524V-G operates at 24V standoff voltage, while NUP4004M5T1G operates at 5V standoff voltage. Direct substitution is only valid if the circuit is designed for 5V protection levels.

Q: What are the key differences between these parts?

A: The primary differences are voltage rating (24V versus 5V standoff), operating temperature range (-55°C to 125°C versus -40°C to 125°C), moisture sensitivity level (MSL-1 versus MSL-3), and product status (obsolete versus active). Package and channel configuration are identical.

Q: Does the SOT-23-5 package ensure mechanical compatibility?

A: Both components use the SOT-23-5 package family, ensuring identical PCB footprint and assembly process compatibility. The NUP4004M5T1G uses a thin variant (TSOT-23-5), which maintains dimensional compatibility with standard SOT-23-5 layouts.

Q: What compliance certifications apply to the substitute part?

A: NUP4004M5T1G is RoHS3 compliant and REACH unaffected, matching the regulatory status of the original component. Both carry EAR99 ECCN classification.

Q: How does the moisture sensitivity level affect handling and storage?

A: CEDS0524V-G carries MSL-1 (unlimited moisture sensitivity), requiring no special storage conditions. NUP4004M5T1G carries MSL-3 (168-hour floor life), requiring controlled humidity storage and bake-out procedures before reflow soldering if moisture absorption limits are exceeded.
