Equivalent & Substitute Parts for NMH1205DC

Part Overview

The NMH1205DC by Murata Power Solutions Inc. is an isolated module DC-DC converter providing two outputs: +5V and -5V at up to 200mA each, with a nominal input range of 10.8V to 13.2V, rated for 2W power output and 1kV isolation. This through-hole device is housed in a 14-DIP module, measuring 19.6mm x 9.9mm x 7.6mm. It complies with RoHS3 and REACH regulations and is suitable for ITE (Commercial) applications. As this product is designated obsolete, identification of equivalent and substitute parts is necessary for current and future design and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is based strictly on matching the primary functional and electrical parameters required for this DC-DC converter category. The key attributes evaluated include:

• Input voltage range
• Output configuration (number, voltage, and maximum current per output)
• Power capability
• Isolation voltage
• Operating temperature range
• Mounting type
• Package dimensions
• Regulatory compliance (RoHS, REACH)

Only parts matching these defined characteristics have been grouped as substitutes. No assumptions are made regarding compatibility outside the provided parameters.

Parameter Comparison

Engineering Selection Recommendations

The NMH1205DC is classified as obsolete. The MEJ2D1205SC from Murata Power Solutions Inc. is suitable as a substitute according to the provided parameters. Both products are RoHS3 compliant and REACH unaffected, and both satisfy the required input voltage range, output configuration, power level, isolation voltage (MEJ2D1205SC provides higher isolation), operating temperature, and mounting type. Users should consider differences in package style and dimensions as noted in the comparison.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting NMH1205DC with another DC-DC converter?
A1: The primary criteria are matching input voltage range, output voltages and currents, total power, isolation voltage, operating temperature, mounting type, and regulatory compliance.

Q2: Are there differences in package form factor between NMH1205DC and MEJ2D1205SC?
A2: Yes. The NMH1205DC is a 14-DIP Module with 6 leads, measuring 19.6mm x 9.9mm x 7.6mm. The MEJ2D1205SC is a 7-SIP Module with 5 leads, measuring 19.7mm x 10.0mm x 12.7mm.

Q3: Is there any change in electrical performance between the two parts?
A3: Both parts provide +5V and -5V outputs at up to 200mA, with nearly identical efficiency and input range. MEJ2D1205SC offers a higher isolation voltage (5.2 kV) compared to NMH1205DC (1 kV).

Q4: Are both parts compliant with RoHS3 and REACH?
A4: Both the NMH1205DC and the MEJ2D1205SC are ROHS3 compliant and REACH unaffected.

Q5: Does substituting alter the product's regulatory or environmental compliance status?
A5: No. Both the original and substitute parts have identical stated compliance for RoHS3 and REACH according to the provided parameters.
