Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching key electrical and mechanical parameters including number of outputs, input and output voltage ranges, output current, total output power, isolation voltage, operating temperature range, application classification, compliance certifications, and mounting/package style. Only parts from the same category and with directly matching parameters are considered equivalent.

Key parameters included:

• Number of outputs
• Input voltage range (4.5V – 5.5V)
• Output voltage(s) (+9V, -9V)
• Output current (111mA)
• Output power (2W)
• Isolation voltage (1kV)
• Application: ITE (Commercial)
• Operating temperature (-40°C ~ 85°C)
• Mounting and package type

Parameter Comparison

Engineering Selection Recommendations

Both NTH0509MC-R and NMH0509SC are active, RoHS compliant, REACH unaffected, and have an unlimited moisture sensitivity level (MSL 1). They are both classified as EAR99 under ECCN and share the same HTSUS code. Selection between these models can be based strictly on package form factor (surface mount vs. through hole), with all other key compliance and status factors being equivalent as per provided parameters.

Frequently Asked Questions (FAQ)

Q1: Can NMH0509SC be substituted for NTH0509MC-R in all applications?
A1: NMH0509SC matches NTH0509MC-R on all critical electrical, thermal, isolation, and compliance parameters. The main physical difference is NMH0509SC is a through hole device while NTH0509MC-R is a surface mount module.

Q2: Should package/lead form factor be considered before substitution?
A2: Yes, NTH0509MC-R uses a 26-SMD module with 12 leads (surface mount), whereas NMH0509SC is a 7-SIP module with 5 leads (through hole). Compatibility depends on PCB layout and assembly method.

Q3: Are both parts RoHS and REACH compliant?
A3: Both NTH0509MC-R and NMH0509SC are RoHS compliant and REACH unaffected.

Q4: Do both parts maintain the same output voltage and power ratings?
A4: Both parts provide dual outputs of +9V and -9V, each up to 111mA, with a total maximum output power of 2W.

Q5: Is there any difference in operating temperature or efficiency?
A5: Both models operate from -40°C to 85°C with 81% efficiency.

Q6: Can both parts be used in ITE (Commercial) applications?
A6: Yes, both are specified for ITE (Commercial) applications as per the data provided.
