Key Parameters

Substitute Part Grouping Explanation

Substitute parts for KAS2-9 are determined based on adherence to the following key parameters: input voltage range, output voltage, maximum output current, output power, mounting type, package/case, number of outputs, operating temperature, approval agency, and RoHS compliance. Only models matching these parameters within the explicitly listed data are considered as valid alternatives.

Parameter Comparison

Engineering Selection Recommendations

Select substitute AC/DC converters that are RoHS compliant and possess matching or broader certification approvals. For continued availability, prioritize active status in listings. All tabulated substitutes either match or exceed key regulatory and compliance criteria as provided.

Frequently Asked Questions (FAQ)

Q1: What determines if PSK-S2C-9 or TMPS 03-109 can substitute for KAS2-9?
A1: Substitution is determined by matching voltage input and output, output current, output power, mounting type, number of outputs, package, compliance, and applicable approvals.

Q2: Are there packaging differences between KAS2-9 and substitutes?
A2: KAS2-9 and TMPS 03-109 use a 5-DIP module, while PSK-S2C-9 uses a 4-DIP module. Ensure mechanical compatibility with the application PCB layout.

Q3: Does the substitute’s certification match KAS2-9?
A3: Certification approvals differ; confirm that all required regulatory standards (CE, cURus, CB, or UL) are covered by the selected substitute.

Q4: How does product status impact selection?
A4: Select active products when possible to ensure long-term availability. TMPS 03-109 is active, while KAS2-9 and PSK-S2C-9 are both obsolete.

Q5: Can higher output current or power be used safely?
A5: Substitute selection is based only on the parameters provided. Select substitutes within or exceeding the required electrical range as documented above.

Q6: Are there temperature range differences to consider?
A6: KAS2-9 supports -40°C ~ 80°C; substitutes support -40°C ~ 70°C (PSK-S2C-9) or -25°C ~ 70°C (TMPS 03-109). Ensure application requirements are met according to specified ranges.
