Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules for the THL 20-4812WI are selected based strictly on the following allowed parameters: input voltage range, output voltage, maximum output current, power rating, module type, number of outputs, isolation voltage, efficiency, features, package/case, mounting type, and compliance. Only parts meeting or exceeding these specific electrical and mechanical parameters are presented as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The THL 20-4812WI has product status Not For New Designs and is not recommended for new projects requiring long-term supply. The JTK2048S12, provided by XP Power, is listed as Active and maintains ROHS3 compliance, with equivalent or improved electrical and mechanical compatibility. Certifications noted for the JTK2048S12 (including standard number 62368-1) meet current compliance requirements, and the module is classified under the same ECCN and HTSUS codes.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting a substitute for the THL 20-4812WI?
A1: Substitution is based strictly on matching or exceeding the input voltage range, output voltage, maximum output current, number of outputs, power rating, package, isolation voltage, efficiency, features, and compliance status.

Q2: Are the package sizes and mounting types identical between these modules?
A2: Both the THL 20-4812WI and JTK2048S12 use a 6-DIP Module package and through-hole mounting. Dimensions are within the listed tolerances.

Q3: How does the product status affect component selection?
A3: THL 20-4812WI is Not For New Designs, while JTK2048S12 is Active, aligning with requirements for ongoing supply and future-proofing.

Q4: Are there any differences in compliance or environmental status?
A4: Both converters are ROHS3 compliant and are classified as EAR99 under ECCN and 8504.40.9580 under HTSUS. The JTK2048S12 lists an explicit moisture sensitivity level.

Q5: Are the electrical protections and features compatible?
A5: Both modules provide Remote On/Off and Short-Circuit Protection (SCP). The JTK2048S12 includes additional protections: Over Current Protection (OCP) and Over Voltage Protection (OVP).

Q6: Can the substitute part be directly implemented in existing designs using THL 20-4812WI?
A6: Key electrical and mechanical parameters are matched according to the provided specifications, supporting substitution in layouts and applications designed for the specified module footprint and parameters.
