Parameter Comparison

Engineering Selection Recommendations

The LM2750LDX-5.0/NOPB is the direct functional equivalent of the LM2750LDX-5.0. Both devices share identical electrical performance characteristics, output specifications, and package configuration.

The LM2750LDX-5.0/NOPB carries an active product status, ensuring ongoing manufacturer support and availability. This part is ROHS3 compliant, meeting current environmental and regulatory requirements. The LM2750LDX-5.0 is classified as obsolete and is RoHS non-compliant.

For new designs or production transitions, the LM2750LDX-5.0/NOPB is the appropriate selection. For legacy applications currently using the LM2750LDX-5.0, the LM2750LDX-5.0/NOPB provides electrical and mechanical compatibility with improved compliance status.

Frequently Asked Questions (FAQ)

Q: Can the LM2750LDX-5.0/NOPB be used as a direct replacement for the LM2750LDX-5.0?

A: Yes. Both parts share identical electrical specifications, output voltage (5V), output current (120mA), input voltage range (2.7V to 5.6V), switching frequency (1.7MHz), and package configuration (10-WFDFN Exposed Pad). Pin-for-pin and functional compatibility is confirmed.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates the part is supplied without plumbum (lead-free). This reflects the packaging and lead-free compliance status of the component.

Q: Are there differences in moisture sensitivity between these parts?

A: Yes. The LM2750LDX-5.0 has MSL 1 (Unlimited), while the LM2750LDX-5.0/NOPB has MSL 3 (168 Hours). MSL 3 requires controlled storage and handling conditions with a 168-hour floor life after moisture exposure. Appropriate moisture control measures must be implemented during storage and assembly.

Q: What is the impact of RoHS compliance differences?

A: The LM2750LDX-5.0 is RoHS non-compliant, while the LM2750LDX-5.0/NOPB is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the LM2750LDX-5.0/NOPB is the required selection.

Q: Is the package footprint identical between these parts?

A: Yes. Both parts use the 10-WFDFN Exposed Pad package (10-WSON 3x3). PCB layout and assembly processes require no modification.
