Substitute Part Grouping Explanation

Substitute selection for DC-DC converters in the high voltage isolated module category must strictly match parameters critical to electrical and mechanical compatibility. Only parts with equivalent voltage isolation, output voltage, mounting requirements, form factor, and RoHS compliance are considered. Substitute relationships are based on direct comparison of:

Output Voltage
Input Voltage Range
Output Current (Max)
Power Rating
Number of Outputs
Mounting Type and Package / Case
Voltage Isolation
Operating Temperature Range
RoHS Compliance

Engineering Selection Recommendations

The QH015-12 is obsolete. When selecting a substitute, confirm product status (active recommended over obsolete), compliance with RoHS3, and comparable input/output characteristics. Q015-5 is active, RoHS3 compliant, and matches core electrical and mechanical parameters defined for this product category within the provided values.

Frequently Asked Questions (FAQ)

Q1: How does Q015-5 differ from QH015-12 aside from input voltage range and output current?
A1: Based on the provided parameters, Q015-5 has a lower input voltage maximum (5V vs. 12V) and lower output current (3.333mA vs. 8.33mA) and power rating (500mW vs. 1.25W). All other listed fields, including output voltage, isolation voltage, package, mounting type, and temperature range, are equivalent.

Q2: What are the critical considerations for substituting high voltage isolated DC-DC converters?
A2: Key considerations are matching output voltage, voltage isolation, mounting type, package/case, RoHS compliance, and ensuring that the input voltage range and output current requirements are compatible with application needs, strictly as per the provided specifications.

Q3: Are form factor and mounting type identical between QH015-12 and Q015-5?
A3: Yes, both use a 4-DIP Module case with through hole mounting and identical physical dimensions per the input data.

Q4: Is Q015-5 compliant with RoHS3 standards?
A4: Yes, both QH015-12 and Q015-5 are listed as ROHS3 Compliant.

Q5: Why is it necessary to select an active substitute part?
A5: The main part, QH015-12, is marked as obsolete, so ensuring continuity of supply, availability, and compliance is only possible by selecting an active substitute such as Q015-5.
