Substitute Part Grouping Explanation

Equivalent and substitute part grouping for DC DC converters in this category is based strictly on core electrical and mechanical parameters. Substitution is determined by matching or exceeding the following key parameters: Type (Isolated Module), Number of Outputs, Input Voltage Range, Output Voltage, Output Current, Power Rating, Voltage Isolation, Efficiency, Operating Temperature, Mounting Type, Package/Case, Application, and RoHS Compliance. Only models meeting these allowed values and attributes are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

UWR-3.3/8-D12A-C is an obsolete DC DC converter. VCD40-D12-S3R3 from CUI Inc. is a substitute part with similar electrical and mechanical characteristics and an active status. Both are RoHS compliant and suitable for ITE (Commercial) applications. VCD40-D12-S3R3 offers equal or higher ratings across all critical electrical and thermal parameters as listed.

Frequently Asked Questions (FAQ)

Q1: What are the core substitution criteria for DC DC converter modules in this reference?
A1: Substitution requires alignment in type (Isolated Module), number of outputs, input voltage range, output voltage, output current, power rating, isolation voltage, efficiency, operating temperature, mounting type, package/case, application, and RoHS status.

Q2: Are package and mounting types considered in equivalency?
A2: Yes. The main part uses through-hole mounting in an 8-DIP module, and the substitute uses through-hole mounting in a 9-DIP module. Both are suitable for comparable PCBs but may differ in lead configuration and footprint.

Q3: Is the substitute part VCD40-D12-S3R3 RoHS compliant and suitable for the same application environment?
A3: Both UWR-3.3/8-D12A-C and VCD40-D12-S3R3 are RoHS compliant and specified for ITE (Commercial) applications.

Q4: Should temperature and efficiency be confirmed when selecting a substitute?
A4: Provided data confirms the operating temperature and efficiency parameters for both parts are identical and sufficient for most commercial ITE environments.

Q5: What inventory status differences exist between the main and substitute parts?
A5: The main part is obsolete with available inventory. The substitute part VCD40-D12-S3R3 is active with available inventory.
