Equivalent & Substitute Parts for NMV1209SC

Part Overview

Murata Power Solutions Inc.'s NMV1209SC is an obsolete isolated module DC-DC converter, providing dual outputs of +9V and -9V at up to 55mA each, with a 1W output power rating. The device is designed for ITE (Commercial) applications, with a 3 kV isolation voltage, -40°C ~ 85°C operating temperature range, and is mounted in a 7-SIP through-hole package. Due to its obsolete product status, identifying direct equivalents and substitutes is essential to maintain ongoing designs, support repairs, and facilitate second sourcing without circuit redesign.

Substitute Part Grouping Explanation

Substitute and equivalent parts for the DC-DC converter NMV1209SC are grouped strictly according to matched electrical and mechanical parameters. Substitution logic in this category is based only on:

• Output voltages and configuration (dual output: +9V and -9V)
• Output current rating (55mA per output)
• Input voltage range (10.8V – 13.2V)
• Power rating (1W)
• Isolation voltage (minimum required or higher)
• Package type (7-SIP Module, 5 Leads, through-hole)
• Operating temperature range
• Regulatory status as provided (ROHS3, REACH, etc.)

Only parts matching or exceeding these parameters are considered direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection between NMV1209SC and MEJ1D1209SC can be based on product status, regulatory compliance, and inventory availability. NMV1209SC is obsolete, while MEJ1D1209SC is active and ROHS3 compliant. Both provide similar electrical and mechanical parameters. Review the REACH status difference, as NMV1209SC is REACH Unaffected and MEJ1D1209SC is REACH Affected, if relevant to end-application requirements.

Frequently Asked Questions (FAQ)

Q1: What parameters determine if MEJ1D1209SC is a substitute for NMV1209SC?
A1: The parameters are identical output voltages (+9V, -9V), current capability (55mA per output), input range (10.8V–13.2V), power rating (1W), isolation voltage equal or higher (5.2 kV vs. 3 kV), identical package and operating temperature.

Q2: Are there mechanical or mounting differences?
A2: Both NMV1209SC and MEJ1D1209SC use the 7-SIP Module, 5 Leads through-hole package.

Q3: Do both parts meet RoHS requirements?
A3: NMV1209SC and MEJ1D1209SC are both ROHS3 Compliant.

Q4: Do both modules have the same efficiency?
A4: The efficiency differs slightly: NMV1209SC (74%), MEJ1D1209SC (73%).

Q5: Is there any difference in REACH status?
A5: NMV1209SC is REACH Unaffected; MEJ1D1209SC is REACH Affected.

Q6: Is additional evaluation required for package fit or pinout?
A6: Both provide the same mechanical outline: 7-SIP Module, 5 Leads, through-hole. All compatibility is based strictly on input package data.
