Engineering Selection Recommendations
Main part KWS5-5 is obsolete; substitutes KWS5A-5 and KPSA5-5 both have active product status, suitable for new and continued designs. Both substitutes support similar ITE (Commercial) applications, universal AC input, and through hole mounting. Approval agencies and regulatory compliance are highlighted, including CE and CSA. RoHS and REACH statuses are provided for substitutes. Package and enclosure type differ; direct selection should be strictly based on required mechanical configuration and regulatory certifications as specified.
Frequently Asked Questions (FAQ)
Q1: What are the primary substitute criteria for KWS5-5?
A1: Output voltage, power rating, input voltage range, application, mounting type, and regulatory approvals are the main substitution criteria.
Q2: How do package/case differences affect selection?
A2: KWS5-5 uses a 5-DIP module enclosed package; substitutes vary in enclosure and module size. Mechanical compatibility with the target application must be verified using provided dimensions and package style.
Q3: Are there differences in agency approvals or compliance?
A3: Substitute parts vary in approval agencies. KWS5A-5 lists CE approval, KPSA5-5 lists CE, CSA, EN, and UL. RoHS and REACH statuses are specified where applicable.
Q4: Does output current affect substitution?
A4: KWS5-5 and KWS5A-5 specify 1A max output current; KPSA5-5 output current value is not explicitly provided. For designs requiring defined output current, parts with specified ratings should be selected.
Q5: Can substitutes operate over the same temperature range?
A5: KPSA5-5 operates from 0°C; KWS5-5 and KWS5A-5 operate from -10°C per provided data. Maximum derated temperature differs; confirm suitability per application requirements.
