Equivalent & Substitute Parts for NME1209SC

Part Overview

NME1209SC is a DC-DC converter from Murata Power Solutions Inc., featuring an isolated module configuration with a single 9V output rated at 111mA and 1W. The module supports input voltages from 10.8V to 13.2V, supplies an output with 1kV isolation, and is intended for ITE (Commercial) applications. Although this part is RoHS3 compliant and has unrestricted MSL, its status is obsolete, making the selection of substitute models required for ongoing designs or maintenance activities to ensure supply continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection is based exclusively on matching the key electrical, mechanical, and compliance parameters established for isolated DC-DC converter modules in this category. Substitution is determined by:

• Input voltage range (10.8V–13.2V)
• Output voltage (9V)
• Output current (111mA)
• Power rating (1W)
• Isolation voltage (≥1kV)
• Package/case format (4-SIP Module)
• Mounting type (Through Hole)
• Operating temperature range (-40°C to 85°C)
• Regulatory compliance status (RoHS3, REACH) The substitute must match or exceed these parameters to ensure direct replacement without deviation from the provided specifications.

Parameter Comparison

Engineering Selection Recommendations

NME1209SC is obsolete. NKE1209SC is in active production, matching all key electrical and mechanical parameters including input voltage range, output voltage/current, power rating, compliance, mounting style, and case format. Both parts hold ROHS3 and REACH certifications. Selection of NKE1209SC as a direct substitute aligns with supply chain requirements for compliant, currently available parts in this DC-DC converter category.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters required for substitution in the DC-DC converter category?
A: Substitution requires matching input voltage range, output voltage/current, power rating, isolation voltage, mounting type, package/case, operating temperature, and compliance certifications.

Q: Is the package format and footprint of NKE1209SC compatible with NME1209SC?
A: Both use the 4-SIP Module form factor. Dimensions are similar, with minor variation in height (NKE1209SC: 0.29" vs NME1209SC: 0.39"). Check mechanical fit if height tolerance is critical.

Q: Does the substitute part meet or exceed the required isolation voltage?
A: NKE1209SC provides 3 kV isolation, exceeding NME1209SC’s 1 kV.

Q: Are there differences in efficiency or thermal parameters affecting selection?
A: NKE1209SC offers a higher efficiency (78%) than NME1209SC (74%), with matched operating temperature range.

Q: Are regulatory compliance and documentation equivalent between both models?
A: Both are ROHS3 Compliant and REACH Unaffected, with equivalent ECCN and HTSUS classification for commercial ITE applications.
