Engineering Selection Recommendations

The NKA0505DEC is designated as obsolete, while the NMA0505DC is listed as active. Both parts conform to ROHS3 and REACH requirements. Product status should be a primary consideration when selecting substitute components to support availability and compliance. Only use models that satisfy the regulatory status and applicable certifications specified for intended applications.

Frequently Asked Questions (FAQ)

Q1: What criteria determine if the NMA0505DC can substitute the NKA0505DEC?
A1: Substitution is determined by matching the isolated DC DC converter type, number of outputs, output voltages and current ratings, input voltage range, power rating, mounting type, package style, and compliance certifications.

Q2: Are the physical package sizes of NKA0505DEC and NMA0505DC identical?
A2: Both parts are supplied in a 14-DIP module with 6 leads. The length and width are closely matched; the height differs slightly.

Q3: Does the difference in voltage isolation impact substitution?
A3: The voltage isolation ratings differ (NKA0505DEC: 3 kV, NMA0505DC: 1 kV). This rating must be considered in applications requiring specific isolation standards.

Q4: Is the mounting method the same for both models?
A4: Both parts offer through-hole mounting in a 14-DIP module package.

Q5: What is the compliance status of these models?
A5: Both NKA0505DEC and NMA0505DC are ROHS3 compliant and unaffected by REACH regulation.
