Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converter modules are grouped strictly based on matching the following key electrical and mechanical parameters:

• Voltage Input Range (21.6V to 26.4V)
• Number of Outputs (2)
• Output Voltages (+9V, -9V)
• Output Current (111mA per output)
• Output Power (2 W)
• Voltage Isolation (1 kV)
• Efficiency (85%)
• Operating Temperature Range (-40°C ~ 85°C)
• Mounting Type (Through Hole)
• Regulatory Compliance (RoHS status, REACH status)
• Moisture Sensitivity Level (MSL 1)
• Base Product Number

Only parts satisfying all these parameters are listed as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The NMH2409DC is obsolete, while the substitute NMH2409SC is currently active. Both are compliant with RoHS and REACH requirements and have identical MSL ratings. Regulatory status and ongoing product support favor the selection of NMH2409SC as a direct substitute based on the provided compliance and product life cycle data.

Frequently Asked Questions (FAQ)

Q1: What criteria determine if NMH2409SC is a valid substitute for NMH2409DC?
A1: The NMH2409SC matches all critical electrical parameters: input voltage range, output voltages, output current, isolation, efficiency, operating temperature, regulatory compliance, and mounting type.

Q2: Are there any differences in package or mechanical dimensions?
A2: Yes, NMH2409SC uses a 7-SIP Module, 5 Leads package (0.77" x 0.30" x 0.40"), while NMH2409DC uses a 14-DIP Module, 6 Leads package (0.77" x 0.39" x 0.30"). Compatibility should be confirmed at the PCB layout and mechanical level using precise measurements provided.

Q3: Is there any difference in environmental or regulatory status?
A3: Both parts are RoHS and REACH compliant and feature the same Moisture Sensitivity Level (MSL 1, Unlimited).

Q4: Is the substitute NMH2409SC in active production?
A4: Yes, NMH2409SC is listed as an active product.

Q5: How do I ensure electrical compatibility when substituting?
A5: Only listed and compared parameters ensure substitution: input voltage range, number of outputs, output voltages/currents, isolation, efficiency, temperature range, and regulatory compliance.

Q6: Does the change in package style affect mounting?
A6: The substitute utilizes a different package and lead count. Review detailed provided package and mechanical dimensions to determine compatibility with existing board layouts.
