Equivalent & Substitute Parts Reference: NKA0515DC

Part Overview

NKA0515DC is an isolated DC-DC converter module manufactured by Murata Power Solutions Inc., featuring dual outputs of +15V and -15V at a maximum of 33mA each. With a 1W power rating and a wide input voltage range (4.5V–5.5V), it targets ITE (Commercial) applications requiring compact, efficient isolated power delivery. This product is currently obsolete, making it necessary to identify suitable substitutes with strictly matching electrical, mechanical, and regulatory parameters for continued design support and inventory planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are identified strictly based on electrical parameters (input voltage range, output voltages, output current, power rating, isolation voltage), mechanical attributes (mounting type, package/case, size/dimension), and compliance certifications (RoHS, REACH, ECCN, HTSUS). Only parts matching all listed fields are included in this equivalence reference.

Parameter Comparison

Engineering Selection Recommendations

NKA0515DC is listed as obsolete. NMA0515DC offers an active product status and matches all compliance, regulatory, mounting, and package standards specified in the input parameters.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting NKA0515DC with another part?
A1: Substitute parts must have identical input voltage range, output voltages, output current, power rating, mounting type, package/case specification, and meet the same RoHS, REACH, ECCN, and HTSUS requirements.

Q2: Does NMA0515DC fit mechanically and electrically as a substitute for NKA0515DC?
A2: NMA0515DC provides the same voltage input and output specifications, current rating, power, mounting type, and package/case. The only significant difference is in isolation voltage and module height.

Q3: Are there compliance differences between the two models?
A3: Both NKA0515DC and NMA0515DC are ROHS3 compliant, REACH unaffected, and share the same ECCN and HTSUS codes.

Q4: What packaging options are available for NMA0515DC compared to NKA0515DC?
A4: NMA0515DC is supplied in tubes, while NKA0515DC specifies unspecified packaging. Both share the 14-DIP Module, 6 Leads package/case.

Q5: Does the operating temperature range differ between these substitutes?
A5: Both parts specify an operating temperature range of -40°C ~ 85°C.

Q6: Is there a difference in efficiency between the models?
A6: NKA0515DC specifies 79% efficiency, while NMA0515DC specifies 78% efficiency.

Q7: What is the key mechanical difference between the substitute and the original?
A7: NMA0515DC is slightly taller (0.27" vs. 0.21" in height). All other mechanical and electrical parameters provided are matched.
