Substitute Part Grouping Explanation

Substitute models are grouped based on strict equivalence in electrical and mechanical specifications. The parameters governing allowable substitution for isolated module DC-DC converters in this group include: number of outputs, output voltages, input voltage range, maximum output currents, power rating, isolation voltage, mounting type, operating temperature range, overall package dimensions, and compliance standards. Only substitutes matching these listed parameters are considered valid.

Parameter Comparison

Engineering Selection Recommendations

Substitution is driven by the main part's obsolete status and the need for continued compliance in certified applications. Substitute part PES1-S12-D24-M-TR from CUI Inc. meets all provided electrical, mechanical, and regulatory parameters, including RoHS compliance and matching ECCN and HTSUS codes. Its active product status and similar package characteristics support direct replacement where identical specifications and compliance requirements are mandated.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria when selecting a substitute for ISA1224-H DC-DC converters?
A1: Substitution requires identical electrical ratings (number of outputs, output voltages, currents, input voltage range, power, isolation), package size, mounting type, temperature range, features, and regulatory compliance.

Q2: Does the substitute PES1-S12-D24-M-TR fit mechanically where ISA1224-H was used?
A2: PES1-S12-D24-M-TR features the same size and surface-mount style, facilitating mechanical compatibility in designs that previously accommodated ISA1224-H.

Q3: Are there any differences in compliance or certifications between ISA1224-H and PES1-S12-D24-M-TR?
A3: Both meet RoHS compliance and share ECCN and HTSUS classifications. Approval agency details and standard numbers are provided for PES1-S12-D24-M-TR.

Q4: How does the package/case compare between the parts?
A4: Both are surface mount modules with 6 leads, in similar compact dimensions, though the main part is a 10-SMD module and the substitute is an 8-SMD module.

Q5: What are the inventory statuses for ISA1224-H and PES1-S12-D24-M-TR?
A5: ISA1224-H is obsolete with stock available; PES1-S12-D24-M-TR is active and available in multiple packaging options with current inventory.
