Engineering Selection Recommendations

Substitute parts KPSA10-5 and KPSB25-5 are both active, RoHS compliant, and maintain required agency certifications. Both models match the mounting, package, output voltage, and are suitable replacements for TDK-Lambda KPS10-5 in designs requiring single-output 5V AC/DC conversion within 4-DIP modules. Selection should be based on active lifecycle status and matching compliance documentation.

Frequently Asked Questions (FAQ)

What parameters must match for an AC/DC converter substitute in the open frame category?

Substitution requires identical type (open frame), input voltage range, output voltage, number of outputs, mounting type, package, agency approvals, and RoHS status.

Can the power rating differ between main and substitute models?

The substitute may have an equal or higher power rating. KPSB25-5 offers higher output power and current compared to KPS10-5.

Is dimensional compatibility mandatory?

Package and mounting type must match. Dimensional variations within the same package/case are allowable if assembly and footprint requirements are met.
