Equivalent & Substitute Parts Reference: NTA0305MC

Part Overview

The NTA0305MC (Murata Power Solutions Inc.) is an isolated module DC-DC converter offering two outputs: +5V and -5V at a maximum output current of 100mA each, with a total power rating of 1 Watt. It operates over a 2.97V–3.63V input voltage range, provides 1 kV isolation, and is supplied as a surface mount 18-SMD module. The device is categorized as obsolete, necessitating consideration of substitute models for ongoing design support, maintenance, and inventory assurance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for DC-DC converters in the isolated module category are grouped by strict equivalence or similarity in key operational parameters: input voltage range, output voltages, maximum output currents, output power, isolation voltage, number of outputs, operating temperature range, efficiency, regulatory and compliance status, and mechanical attributes including mounting type and package dimensions. Substitution requires exact or closely matched values in these categories. No functional extrapolation or undocumented equivalence is employed.

Parameter Comparison

Engineering Selection Recommendations

Given the obsolete status of the NTA0305MC, use of an active substitute, such as the NKA0305SC, ensures continuity of supply and compliance with industry standards. Both parts are ROHS3 compliant and REACH unaffected, with ECCN and HTSUS classifications matched. The substitute offers active status, facilitating ongoing procurement and new designs.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters must be matched for substitution?
A1: Input voltage range, output voltages, maximum output currents, power rating, isolation voltage, and operating temperature range must all be matched to maintain electrical functionality.

Q2: Can mechanical package differences impact interchangeability?
A2: Yes. NTA0305MC uses a surface mount 18-SMD package, while NKA0305SC uses a through-hole 6-SIP package. Selection requires assessment of board layout and mounting compatibility.

Q3: Are both parts compliant with RoHS and REACH requirements?
A3: Yes. Both NTA0305MC and NKA0305SC are ROHS3 compliant and REACH unaffected.

Q4: Is the input voltage tolerance identical between the two parts?
A4: The input voltage ranges are similar but not identical. NTA0305MC supports 2.97V–3.63V; NKA0305SC supports 3V–3.6V.

Q5: How are differences in isolation voltage addressed?
A5: Isolation voltage for NTA0305MC is 1 kV, while NKA0305SC offers 3 kV. Substitution maintains or increases isolation capability.

Q6: What product status differences should be considered?
A6: The NTA0305MC is obsolete; the NKA0305SC is active, supporting ongoing purchasing and design deployment.

Q7: Are output specifications for both parts equivalent?
A7: Yes. Both offer two outputs at +5V and -5V, with a maximum output current per channel of 100mA and total output power of 1W.
