Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converters are grouped strictly by matching primary functional parameters, including type (isolated module), number of outputs, input and output voltage ranges, maximum output current capability, isolation voltage, mounting type, intended applications, operating temperature range, package/case, and environmental compliance status. These parameters are necessary to maintain form, fit, and functional compatibility within existing assemblies.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute DC-DC converters such as the TRI 3-4823 from Traco Power is based on status (active vs. obsolete), RoHS3 compliance, and availability of recognized certifications (CB, cURus). Only parameters explicitly given are used for establishing equivalence in electrical and package characteristics.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting the IA4815S DC-DC converter?
A1: Key criteria are type (isolated module), number of outputs, input and output voltage ranges, maximum output current, isolation voltage, mounting type, applications, operating temperature, package/case, and RoHS compliance.

Q2: Are TRI 3-4823 modules compatible as replacements for the IA4815S?
A2: TRI 3-4823 meets or exceeds the key electrical and mechanical criteria listed in the parameter table. It is categorized as an active part and offers dual output voltages of ±15V with similar or higher performance metrics.

Q3: Will the package or pin layout differences affect direct replacement?
A3: The IA4815S uses a 5-SIP Module, while TRI 3-4823 is specified in a 24-DIP Module, 6 Leads. Verification of mechanical compatibility with existing PCB footprints is required using manufacturer-provided package/case information.

Q4: What environmental and certification statuses must be considered?
A4: Both IA4815S and TRI 3-4823 are RoHS3 compliant. The TRI 3-4823 also lists CB and cURus agency approvals. Parameter-based selection ensures alignment with required compliance criteria.
