CES48033-30P-R Equivalent & Substitute Parts Reference
Part Overview
The CES48033-30P-R by Cosel USA, Inc. is an obsolete isolated DC-DC converter module with a single 3.3V output at up to 30A, a 36V–76V input range, and 99W maximum power. As this part has reached obsolete status, finding suitable substitute parts is necessary to maintain ongoing product designs and ensure supply chain continuity.

Substitute Part Grouping Explanation
Substitution is determined strictly by matching the following key parameters:
- Input Voltage Range (36V – 76V)
- Output Voltage (3.3V)
- Output Current (maximum value)
- Type (Isolated Module)
- Number of Outputs (1)
- Package / Case (8-DIP Module)
- Mounting Type (Through Hole)
- Application (ITE Commercial)
- Operating Temperature Range (-40°C ~ 85°C)
- RoHS Compliance
Where the output current is lower than the CES48033-30P-R, the substitute can only provide up to its rated current. Other features (such as isolation voltage, additional protection functions, or efficiency) are compared as per provided parameters.

Engineering Selection Recommendations
The CES48033-30P-R is obsolete. Substitute part numbers CHS120483R3 and CHS80483R3-R are ROHS3 Compliant and have the same through-hole, 8-DIP module package and input/output voltage ranges. CHS120483R3 matches the output current (30A), while CHS80483R3-R has a lower maximum output current (25A). Both substitutes are active and suitable for designs requiring RoHS compliance and similar electrical/mechanical characteristics as explicitly detailed above.
Frequently Asked Questions (FAQ)
Q: What criteria must substitute DC-DC converters meet for CES48033-30P-R replacement?
A: Substitute parts must match the input voltage range (36V–76V), output voltage (3.3V), output current (30A or higher), isolated module type, single output, 8-DIP through-hole package, ITE commercial application rating, operating temperature range (-40°C ~ 85°C), and RoHS3 compliance, based strictly on provided data.
Q: Is the package or footprint the same for all substitute parts?
A: All listed substitutes use the 8-DIP module through-hole package, aligning with the original part’s mechanical configuration per the provided specifications.
Q: Are the substitute parts RoHS compliant and suitable for ITE (Commercial) use?
A: Both CHS120483R3 and CHS80483R3-R are explicitly specified as ROHS3 Compliant and support ITE (Commercial) applications.
Q: Can CHS80483R3-R be used when full 30A output is required?
A: CHS80483R3-R supports a maximum output current of 25A. It is suitable only where 25A output is sufficient.
Q: Are there efficiency or isolation voltage differences to consider?
A: CHS120483R3 and CHS80483R3-R feature higher efficiency and a higher rated isolation voltage than CES48033-30P-R, as shown in the parameter comparison table above.
Q: Do the substitute products have similar operating temperature ratings?
A: All listed parts have an operating temperature range of -40°C ~ 85°C (With Derating) per provided data.
