Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching the following key parameters: type (isolated module), input voltage range (4.5V–5.5V), output voltages (+5V, -5V), output currents (100mA/channel), power rating (1 W), number of outputs (2), mounting type (through hole), package form (14-DIP Module, 6 Leads), operating temperature range (-40°C to 85°C), RoHS and REACH compliance. Substitute parts are listed only if they meet these explicit criteria and have an active product status.

Parameter Comparison

Engineering Selection Recommendations

The NKA0505DC is obsolete while all substitute parts listed, including NMA0505DC, are active. All listed substitutes have RoHS3 compliance and REACH unaffected status. Selection should prioritize availability and compliance based solely on the provided certifications and active product status.

Frequently Asked Questions (FAQ)

Q1: What is the main criterion for selecting an NKA0505DC substitute?
A1: Substitution is determined strictly by matching the input voltage range, output voltages, output currents, power rating, number of outputs, mounting type, operating temperature range, package, and compliance statuses.

Q2: Is the package form factor identical between NKA0505DC and its substitute NMA0505DC?
A2: Both parts share the 14-DIP Module, 6 Leads package type; small dimensional differences exist as specified.

Q3: Does the substitute offer the same isolation voltage as the original?
A3: The NMA0505DC isolate voltage is 1 kV compared to the NKA0505DC’s 3 kV. This parameter difference is explicit in the provided technical data.

Q4: How do compliance certifications compare between substitute and original parts?
A4: Both NKA0505DC and NMA0505DC are ROHS3 compliant and REACH unaffected.
