Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDMSP10-0504M is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Steering (Rail to Rail) TVS diode topology with 4 unidirectional channels
• Voltage - Reverse Standoff: 5V (Max)
• Voltage - Breakdown (Min): 6V
• Voltage - Clamping (Max) @ Ipp: within acceptable range (12.5V nominal)
• Power Line Protection capability: Yes
• Surface mount packaging configuration
• RoHS3 compliance and MSL 3 rating

The CDDFN10-0524P meets these criteria as an active-status alternative from the same manufacturer, offering equivalent electrical protection characteristics with a different package form factor (10-DFN vs. 10-MSOP).

Parameter Comparison

Engineering Selection Recommendations

The CDDFN10-0524P is the primary substitute for the obsolete CDMSP10-0504M based on the following factors:

Product Status: The CDDFN10-0524P maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete CDMSP10-0504M.

Electrical Equivalence: Both components share identical reverse standoff voltage (5V Max), breakdown voltage (6V Min), and clamping voltage specifications within acceptable tolerance (12.5V vs. 12V Typ). The 4-channel steering topology and power line protection capability are preserved.

Compliance: Both parts maintain ROHS3 compliance and identical MSL 3 ratings, ensuring compatibility with standard manufacturing and storage protocols.

Package Consideration: The CDDFN10-0524P uses a 10-DFN (2.5x1) package versus the 10-MSOP package of the main part. PCB layout modifications are required to accommodate the different footprint geometry.

Frequently Asked Questions (FAQ)

Q: Can the CDDFN10-0524P directly replace the CDMSP10-0504M without PCB modifications?

A: No. While the electrical characteristics are equivalent, the package form factors differ (10-DFN vs. 10-MSOP). PCB footprint redesign is necessary. The 10-DFN (2.5x1) package has different pin spacing and dimensions compared to the 10-MSOP package.

Q: Are the voltage protection characteristics identical between these parts?

A: The reverse standoff voltage (5V Max) and breakdown voltage (6V Min) are identical. The clamping voltage differs slightly (12.5V vs. 12V Typ), which remains within acceptable operating margins for HDMI and Ethernet protection applications.

Q: What is the primary advantage of selecting the CDDFN10-0524P?

A: The CDDFN10-0524P maintains active product status with established supply chain availability, whereas the CDMSP10-0504M is obsolete. This ensures long-term procurement reliability and manufacturing support.

Q: Are both parts suitable for the same applications?

A: Both parts provide power line protection for HDMI applications. The CDMSP10-0504M lists Ethernet as an additional application; however, the CDDFN10-0524P electrical specifications support equivalent protection for both interface types.

Q: Do both parts meet the same compliance and moisture sensitivity requirements?

A: Yes. Both components are ROHS3 compliant with MSL 3 (168 Hours) ratings, ensuring compatibility with standard surface mount assembly and storage conditions.
