Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly based on electrical and mechanical parameters found in both the main part and the available substitute models. These include input voltage range, output voltage and current, maximum output power, isolation voltage, number of outputs, package type and dimensions, operating temperature, mounting type, RoHS compliance, and application suitability. Substitute parts must match or exceed these characteristics to ensure compatibility for direct replacement in designs.

Parameter Comparison

Engineering Selection Recommendations

THL 20-4813WI is indicated as "Not For New Designs." JTK2048S15 (XP Power) is identified with "Active" product status, matching all relevant compliance fields, including ROHS3 status, ECCN, and HTSUS code. Both belong to the DC DC Converter isolated module category and share equivalent package type, input/output voltage ranges, power handling, mounting style, and application rating per provided parameters.

Frequently Asked Questions (FAQ)

Q: What factors determine whether JTK2048S15 can substitute for THL 20-4813WI?
A: The defining parameters are input voltage range (18V-75V), output voltage (15V), maximum output current (≥1.33A), isolated module type, package (6-DIP Module), mounting style (through hole), application (ITE commercial), and compliance (ROHS3).

Q: Are there notable package or mechanical differences between the parts?
A: The package and size parameters are nearly identical: THL 20-4813WI is 1.00" L x 1.00" W x 0.40" H, while JTK2048S15 is 1.00" L x 1.00" W x 0.39" H. Both share the 6-DIP Module case and through-hole mounting.

Q: Does the substitute part meet all compliance requirements?
A: Both THL 20-4813WI and JTK2048S15 are ROHS3 compliant per provided data.

Q: Are substitute parts suitable for the same application category?
A: Both parts target ITE (commercial) applications according to the provided descriptions.

Q: Is efficiency or isolation voltage a substitution concern?
A: Efficiency and isolation voltage are closely matched (89% vs 90%; 1.5 kV vs 1.6 kV), fulfilling typical substitution criteria for DC DC converters in this category per provided fields.
