Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined based on strict matching of key electrical and mechanical parameters supplied for the DC-DC converter module category. The following parameters are used in the substitution logic: input voltage range, output voltage, maximum output current, power rating, isolation voltage, number of outputs, mounting type, package/case, operating temperature, and application domain. Only parts that meet or exceed these specifications within the stated conditions can be considered equivalent or substitutes. Compliance certifications and product activity statuses also define suitability for replacement.

Parameter Comparison

Engineering Selection Recommendations

ISE1209A is obsolete. IES0112S09 is active and shares identical key electrical and mechanical parameters. IES0112S09 has updated compliance certifications, including CE, UKCA, and UL, with RoHS3 compliance. As both parts match on input/output voltage ranges, current, isolation, and surface-mount package considerations, and the substitute features an active product status with applicable certifications, IES0112S09 is a suitable direct replacement within the context of the provided technical parameters.
