Engineering Selection Recommendations

Murata HPQ-12/25-D48PBH-C is currently obsolete and listed as ROHS3 compliant with unaffected REACH status. Its substitute, OmniOn Power QBVW025A0BZ, is designated as active and is RoHS compliant. Both products share identical electrical, mechanical, and compliance parameters as outlined. Product selection can be based on stock availability and compliance requirements matching those listed.

Frequently Asked Questions (FAQ)

Q1: What parameters are required for substituting HPQ-12/25-D48PBH-C?
A1: Substitution is permitted if the alternative matches input voltage range, output voltage/current, total power, isolation rating, temperature range, mounting type, package, physical dimensions, control features, number of outputs, application type, and primary features.

Q2: Does the package and mounting type affect suitability?
A2: Yes, the substitute part must have the same Through Hole mounting and compatible 8-DIP Module (1/4 Brick) package dimensions.

Q3: Are all features present in the substitute?
A3: Substitute parts must match listed features such as Remote On/Off, overcurrent, overtemperature, overvoltage, undervoltage protection, and control configuration.

Q4: How does product status influence part selection?
A4: An obsolete status necessitates the use of an active substitute with directly matching critical parameters.

Q5: Do compliance marks (RoHS, REACH) need to match?
A5: Substitute selection follows identical compliance and certification requirements stated in the provided data.

Q6: Is efficiency a selection parameter in this category?
A6: Efficiency is listed and compared, but substitution is allowed as long as key electrical and mechanical parameters are directly matched.
