• Isolation Voltage: 3kV
• Efficiency: 78%
• Application: ITE (Commercial)
• Operating Temperature: -40°C to 85°C
• Environmental Compliance: ROHS3 Compliant, REACH Unaffected
• Mounting Type: Through Hole
• Package-level differences (shape, size, lead form) are included only if explicitly provided

Substitute parts listed adhere strictly to these provided parameters.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts must consider the product status, environmental compliance, and regulatory registration as explicitly provided. NKE1209DC is obsolete, while NKE1209SC is active and maintains ROHS3 and REACH compliance. Moisture sensitivity registration is unchanged between parts. The substitute part NKE1209SC is suitable for selection when the original part is unavailable, provided the user verifies physical package compatibility as per the defined mounting type and package/case information.

Frequently Asked Questions (FAQ)

Q1: How are substitute parts determined for DC-DC converters like NKE1209DC?
Substitutes are selected based on matching all required electrical parameters (input voltage range, output voltage and current, power rating, isolation voltage, efficiency), application classification, environmental compliance, and mounting type, as explicitly detailed in the specification.

Q2: Is the NKE1209SC a form-fit-function equivalent for NKE1209DC?
NKE1209SC matches all electrical parameters and compliance criteria; package differences exist (8-DIP vs. 4-SIP), which may impact mechanical fit. Both are through-hole types suitable for similar assembly processes.

Q3: Does the substitute maintain the same environmental compliance as the original part?
Both NKE1209DC and NKE1209SC are ROHS3 compliant and REACH unaffected, with "Not Applicable" moisture sensitivity levels.

Q4: What mechanical differences exist between the original and substitute parts?
NKE1209DC uses an 8-DIP Module, 4 Leads package; NKE1209SC uses a 4-SIP Module. Physical size and lead configuration may differ but are both through-hole.

Q5: What should be considered regarding inventory and product status when selecting a substitute?
NKE1209DC is obsolete; therefore, only remaining stock is available. NKE1209SC is active, making it suitable for ongoing supply needs if all allowed parameters are met.
