NKA0503DC Equivalent & Substitute Parts Reference

Part Overview

Murata Power Solutions Inc. part number NKA0503DC is a DC DC converter designed to provide isolated, dual-output voltages of +3.3V and -3.3V at up to 152mA per output from a 4.5V to 5.5V input. This 1W isolated module features a 3 kV voltage isolation rating, is intended for ITE (Commercial) applications, and supports through-hole mounting in a 14-DIP module package. The device is classified as obsolete, making it necessary to identify alternative models with matching electrical and mechanical parameters to ensure continuity in design and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected by matching the following parameters: type (isolated module), number of outputs, input voltage range, output voltage levels, maximum output current, output power rating, voltage isolation, application (ITE – commercial), efficiency, operating temperature range, RoHS and REACH compliance, mounting type, and package/case details. All listed substitute parts provide direct parameter equivalence to the NKA0503DC as detailed above.

Parameter Comparison

Engineering Selection Recommendations

Selection is based on obsolete product status of the NKA0503DC, requiring identification of alternative models with equivalent parameter sets. The listed substitute, NKA0503SC, is RoHS3 compliant, REACH unaffected, and active. Product selection can be conducted based on direct parameter matching and compliance status.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to ensure equivalent substitution for NKA0503DC?
A1: The substitute must meet type (isolated module), number of outputs, input voltage range, output voltage values, maximum output current, output power, voltage isolation, application type, efficiency, operating temperature, RoHS and REACH compliance, mounting type, and package/case specifications.

Q2: Are there mechanical differences between NKA0503DC and its substitute NKA0503SC?
A2: The primary mechanical differences are in the package/case type and the product dimensions: NKA0503DC uses a 14-DIP module with 6 leads (0.77" x 0.39" x 0.21"), whereas NKA0503SC uses a 6-SIP module with 5 leads (0.65" x 0.23" x 0.30").

Q3: Does NKA0503SC provide the same electrical performance as NKA0503DC?
A3: NKA0503SC matches NKA0503DC in all specified electrical parameters, including voltage inputs/outputs, output current, power, and isolation.

Q4: Does the status of RoHS and REACH affect substitute selection?
A4: Yes, both NKA0503DC and NKA0503SC are ROHS3 compliant and REACH unaffected, satisfying standard compliance requirements.

Q5: Is the mounting type consistent between the original and substitute parts?
A5: Both parts utilize through-hole mounting, with variation only in the package form factor (DIP vs. SIP). Consider mechanical compatibility in the end application.
