Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are grouped strictly by the following key parameters: output voltage, output current, input voltage range, total output power, voltage isolation, number of outputs, efficiency, operating temperature range, mounting type, package/case compatibility, application category, features, physical dimensions, and RoHS compliance. Only parts matching these criteria, as explicitly detailed above, are considered direct substitutes within the isolated module category.

Parameter Comparison

Engineering Selection Recommendations

THL 20-4810WI is designated as “Not For New Designs.” JTK2048S3V3 is listed as “Active” and “ROHS3 Compliant.” The substitute part maintains all mandatory electrical, mechanical, and compliance parameters. Both modules feature the same form factor, mounting type, and RoHS status. JTK2048S3V3 offers equivalent output voltage and current ratings, input voltage range, and power output within the isolated module product category.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting THL 20-4810WI with JTK2048S3V3?
A1: Substitution is based on electrical rating (output voltage: 3.3V; output current: 4.5A; input voltage: 18V–75V; power: 15W), mechanical compatibility (6-DIP module package, identical dimensions), isolation rating, application category, compliance (ROHS3), and operating temperature.

Q2: Are there any differences in package size between THL 20-4810WI and JTK2048S3V3?
A2: Both modules specify a 6-DIP module package with nearly identical dimensions (25.4mm x 25.4mm x ~10mm).
