Substitute Part Grouping Explanation

Substitution for Murata NKA1209DC is determined by strict adherence to the following parameters:

• Electrical specification matching: Input voltage range (10.8V – 13.2V), output voltages (+9V, -9V), output power (1W), and maximum output current.
• Functional specification: Dual isolated outputs, module type, and isolation voltage requirements.
• Mechanical specification: 14-DIP module form factor, through-hole mounting, and physical dimensions.
• Environmental and regulatory compliance: RoHS3 compliance, REACH status, ECCN, and HTSUS codes. Only parts meeting all listed criteria can be considered as substitutes in this engineering context.

Parameter Comparison

Engineering Selection Recommendations

NKA1209DC is categorized as obsolete. When selecting alternatives, product status should be prioritized to ensure ongoing supply availability. Both NKA1209DC and NMA1209DC are ROHS3 compliant and have REACH unaffected status, meeting current environmental and chemical standards. The substitute, NMA1209DC, is also classified under ECCN EAR99 and HTSUS 8504.40.9580, indicating consistent regulatory classification. Consider actual product status and compliance for final selection within procurement and design processes.

Frequently Asked Questions (FAQ)

Q1: What are the critical electrical parameters required for substitution between NKA1209DC and NMA1209DC?
A1: Substitution is based on matching input voltage range (10.8V – 13.2V), output voltages (+9V, -9V), output power (1W), and dual output configuration.

Q2: Are there mechanical differences affecting compatibility between NKA1209DC and NMA1209DC?
A2: Both parts share a 14-DIP module, 6-lead through-hole package, with minor differences in physical height. Overall footprint compatibility is maintained.

Q3: What regulatory or compliance considerations must be observed?
A3: Both parts are ROHS3 compliant and REACH unaffected. ECCN and HTSUS codes are identical, supporting regulatory compatibility.

Q4: Does the substitute part NMA1209DC provide the same isolation voltage as NKA1209DC?
A4: NMA1209DC features a lower isolation specification (1 kV compared to 3 kV). Evaluate application requirements against the specified isolation voltage.

Q5: How does efficiency differ between NKA1209DC and its substitute?
A5: NKA1209DC has a higher efficiency rating (79%) compared to NMA1209DC (74%). Assess system requirements where efficiency may be a critical parameter.

Q6: Can NMA1209DC be used on the same PCB footprint as NKA1209DC?
A6: Both parts utilize the 14-DIP module with identical lead configuration, supporting direct mechanical interchangeability. Physical height varies slightly.
