Parameter Comparison

Engineering Selection Recommendations

LP2980AIM5-4.7/NOPB is the primary substitute for the obsolete LP2980AIM5-4.7. This part maintains identical electrical specifications and mechanical compatibility while offering Active product status and ROHS3 compliance. The /NOPB designation indicates lead-free construction. Tape & Reel packaging supports automated assembly processes and provides superior inventory availability with 3200 units in stock.

LP2980IM5-4.7/NOPB serves as a secondary parametric equivalent, maintaining all critical electrical and mechanical parameters. This part carries Obsolete status but offers ROHS3 compliance and Cut Tape & Digi-Reel packaging options. Selection of this part should be based on specific packaging requirements or procurement constraints.

For new designs and ongoing production requiring RoHS compliance and active product support, LP2980AIM5-4.7/NOPB is the recommended selection. For legacy system maintenance where original packaging formats are required, LP2980IM5-4.7/NOPB provides functional equivalence with alternative packaging options.

Frequently Asked Questions (FAQ)

Q: Can LP2980AIM5-4.7/NOPB be used as a direct replacement for LP2980AIM5-4.7?

A: Yes. Both parts are electrically and mechanically identical, with output voltage fixed at 4.7V, output current at 50mA, and identical dropout voltage specifications. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 vs. non-compliant). The /NOPB designation indicates lead-free construction.

Q: What is the difference between the packaging options?

A: LP2980AIM5-4.7/NOPB is supplied in Tape & Reel format, optimized for automated pick-and-place assembly. LP2980IM5-4.7/NOPB is available in Cut Tape and Digi-Reel formats. All three parts use the same SOT-23-5 package footprint and are mechanically compatible on PCBs.

Q: Are all substitute parts RoHS compliant?

A: LP2980AIM5-4.7/NOPB and LP2980IM5-4.7/NOPB are both ROHS3 compliant. The original LP2980AIM5-4.7 is RoHS non-compliant. For applications requiring RoHS compliance, either substitute part is suitable.

Q: What are the key electrical parameters that must match for substitution?

A: Critical parameters include fixed output voltage (4.7V), maximum output current (50mA), maximum input voltage (16V), dropout voltage (0.22V @ 50mA), and protection features (over-current, over-temperature, short-circuit). All listed substitutes maintain these specifications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, all listed parts are pin-compatible and electrically equivalent. No circuit modifications are required. Verify PCB footprint compatibility with SOT-23-5 package specifications before assembly.
