Equivalent & Substitute Parts Reference for NKE0515DC

Part Overview

NKE0515DC is an isolated module DC-DC converter produced by Murata Power Solutions Inc. It provides a single 15V output at up to 66mA from a 4.5V–5.5V input, with a rated isolation voltage of 3 kV and 1W power capability. The module is intended for ITE (Commercial) applications and features a through-hole 8-DIP package. This model is currently obsolete, necessitating the identification of alternative models matching the same electrical, mechanical, and compliance parameters for ongoing system maintenance and new designs.

Parameter Comparison

Engineering Selection Recommendations

NKE0515DC is obsolete; substitution with CRE1S0515SC is possible based on the provided compliance (ROHS3 Compliant, REACH Unaffected), product status (active), and regulatory classification (ITE Commercial). Standard numbers and certifications such as 60950-1 are present in the substitute part listing, matching typical application safety and compliance requirements.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters must be matched when substituting NKE0515DC?
A1: Input voltage range, output voltage, maximum output current, output power, and module type must match.

Q2: What determines mechanical compatibility for a DC-DC converter like NKE0515DC?
A2: Package type and dimensions specify mechanical compatibility. The legacy part uses an 8-DIP package, while the substitute uses a 4-SIP; verify mechanical fit based on these dimensions.

Q3: Is regulatory compliance affected when selecting CRE1S0515SC as a substitute?
A3: Both parts are ROHS3 Compliant and REACH Unaffected, retaining compliance status.

Q4: Are there differences in isolation voltage?
A4: NKE0515DC features 3 kV isolation; CRE1S0515SC specifies 1 kV isolation. Compare application requirements accordingly.

Q5: Do the substitute parts have equivalent operating temperature ranges?
A5: Both DC-DC converters operate from -40°C to 85°C as specified.

Q6: What are the package differences between NKE0515DC and CRE1S0515SC?
A6: NKE0515DC uses an 8-DIP module (11.5mm x 9.8mm x 5.4mm), and CRE1S0515SC uses a 4-SIP module (11.5mm x 6.1mm x 10.0mm). Mechanical compatibility with the PCB layout should be confirmed using these values.
