Key Parameters

Substitute Part Grouping Explanation

Substitution of the NCP45650IMNTWG is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Output current rating: 24A maximum
• Load voltage range: 1V ~ 13.5V
• Supply voltage range: 3V ~ 5.5V
• On-resistance (Rds On): 6.7mOhm typical
• Fault protection features: Current Limiting (Fixed), Over Temperature, Short Circuit, UVLO

Mechanical & Package Specifications:

• Package type: 12-VFDFN Exposed Pad (12-DFN 3x3)
• Mounting: Surface Mount
• Interface: On/Off control, Non-Inverting input

Compliance & Environmental:

• RoHS3 Compliance
• MSL Rating: 3 (168 Hours)
• Operating temperature range: -40°C ~ 85°C

The NCP45651IMNTWG meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the NCP45650IMNTWG and NCP45651IMNTWG are Last Time Buy components from onsemi's ecoSWITCH™ series. Selection between these parts should be based on the following factors:

Inventory Availability: The NCP45651IMNTWG currently has higher inventory availability (6854 Pcs) compared to the NCP45650IMNTWG (4300 Pcs). For applications requiring extended supply assurance, the NCP45651IMNTWG may provide better long-term availability.

Compliance & Regulatory: Both parts maintain identical RoHS3 compliance and MSL ratings. Both are REACH Unaffected. The NCP45650IMNTWG carries ECCN classification EAR99, while the NCP45651IMNTWG carries ECCN 3A991A2. Verify export control requirements for your application jurisdiction.

Electrical & Mechanical Equivalence: The parts are electrically and mechanically identical across all specified parameters. Direct substitution is supported without circuit modification.

Last Time Buy Consideration: Given that both parts carry Last Time Buy status, long-term design planning should account for eventual component discontinuation. Evaluate alternative load switch architectures for future product generations.

Frequently Asked Questions (FAQ)

Q: Are the NCP45650IMNTWG and NCP45651IMNTWG pin-compatible?

A: Yes. Both devices use the 12-VFDFN Exposed Pad package with identical pinout and electrical interface specifications. Direct PCB substitution is supported.

Q: Can I substitute the NCP45651IMNTWG for the NCP45650IMNTWG in an existing design?

A: Yes. The parts are parametric equivalents with identical electrical specifications, output current ratings, voltage ranges, on-resistance, and fault protection features. No circuit redesign is required.

Q: What is the difference between these two part numbers?

A: The NCP45650IMNTWG and NCP45651IMNTWG are functionally equivalent load switches within the ecoSWITCH™ series. The primary differences are the base product number designation and ECCN classification. All electrical and mechanical parameters are identical.

Q: Are both parts suitable for high-current applications?

A: Yes. Both devices support 24A maximum output current with 6.7mOhm typical on-resistance. They include current limiting, over-temperature, short-circuit, and UVLO fault protection suitable for demanding load-switching applications.

Q: What is the MSL rating, and why does it matter?

A: Both parts carry MSL 3 (168 Hours) rating. This indicates the component can be exposed to ambient conditions of 30°C/85% RH for up to 168 hours before soldering. Proper moisture control during storage and handling is required to prevent solder joint defects.

Q: Are these parts RoHS compliant?

A: Yes. Both the NCP45650IMNTWG and NCP45651IMNTWG are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements for EU and global markets.

Q: What operating temperature range do these devices support?

A: Both parts operate across -40°C to 85°C (TA), suitable for industrial and commercial temperature environments.

Q: Why are both parts marked as Last Time Buy?

A: Last Time Buy status indicates that onsemi has announced end-of-life for these components. Existing inventory is available, but production will cease. Plan accordingly for long-term supply requirements or evaluate alternative load switch solutions.
