Substitute Part Grouping Explanation

Substitute selection for DC-DC converters such as ISA2405 requires strict equivalence in the following parameters: input voltage range, output voltage and current ratings, power capacity, isolation voltage, number of outputs, mounting method, and package/case dimensions. Only substitute part numbers matching these mandatory criteria—including the mechanical package—qualify. For regulated engineering workflows, product status, compliance (RoHS, certifications), and approved agency listings further determine suitability.

Parameter Comparison

Engineering Selection Recommendations

IAS0124D05 is further designated "Active," RoHS3-compliant, and possesses certified approvals (CE, UKCA, UL), supporting eligibility for use in ITE (Commercial) applications. Compliance to current standards is strictly maintained by using the substitute IAS0124D05.

Frequently Asked Questions (FAQ)

Q1: What must match to qualify IAS0124D05 as a substitute for ISA2405?
A1: The substitute must match input voltage range, output voltages, maximum output currents, power rating, isolation voltage, number of outputs, package style, mounting method, physical dimensions, and compliance certifications.

Q2: Are there differences in mechanical dimensions between ISA2405 and IAS0124D05?
A2: Both parts share identical length (0.60") and width (0.33"), while height differs slightly (ISA2405: 0.28", IAS0124D05: 0.29").

Q3: Are the mounting type and pad layout compatible between the two models?
A3: Both models feature surface-mount technology and 10-SMD, 6-lead packages, allowing direct mechanical interchangeability.

Q4: What is the effect of operating temperature range compliance?
A4: Both parts offer compatible operating ranges of -40°C to 105°C. For IAS0124D05, operation up to the upper limit is supported with derating.

Q5: Does the substitute IAS0124D05 meet current RoHS and safety requirements?
A5: IAS0124D05 is RoHS3 compliant and certified to CE, UKCA, and UL, supporting updated compliance and approval standards.

Q6: Why is it necessary to find a substitute for ISA2405?
A6: ISA2405 is discontinued, requiring substitution for ongoing production, repairs, and inventory replenishment.

Q7: How does efficiency between ISA2405 and IAS0124D05 compare?
A7: IAS0124D05 features 82% efficiency compared to ISA2405's 80%, within acceptable design margins for replacement.

Q8: Do the parts share identical electrical output characteristics?
A8: Both provide dual outputs: +5V and -5V at 100mA each, qualifying IAS0124D05 as a direct substitute for output requirements.
