Critical Parameters for Substitution:

• Output voltage: 4.7V fixed
• Maximum output current: 50mA
• Maximum input voltage: 16V
• Voltage dropout: 0.22V @ 50mA
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Mounting type: Surface Mount
• Protection features: Over Current, Over Temperature, Short Circuit
• Operating temperature range: -40°C ~ 125°C

The identified substitute parts maintain identical electrical specifications and package configurations, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

LP2980AIM5-4.7/NOPB is the primary substitute for the obsolete LP2980IM5-4.7. This part maintains identical electrical and mechanical specifications while offering Active product status and ROHS3 compliance. The Tape & Reel packaging format supports high-volume production environments.

LP2980IM5-4.7/NOPB provides an alternative substitute with equivalent electrical performance and ROHS3 compliance. This part is also classified as Obsolete but remains available in Cut Tape and Digi-Reel packaging formats, suitable for lower-volume or prototype applications.

Both substitute parts deliver the same functional performance as the original LP2980IM5-4.7 across all critical electrical parameters and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can LP2980AIM5-4.7/NOPB directly replace LP2980IM5-4.7 in existing designs?

A: Yes. Both parts share identical electrical specifications, output voltage, current ratings, dropout voltage, and SOT-23-5 package configuration. Direct substitution is supported without circuit modification.

Q: What is the difference between the substitute parts?

A: LP2980AIM5-4.7/NOPB and LP2980IM5-4.7/NOPB are electrically equivalent. The primary differences are product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. Cut Tape & Digi-Reel). Both meet ROHS3 compliance requirements.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel or Cut Tape) does not affect electrical performance or functional characteristics. Selection depends on procurement volume and assembly process requirements.

Q: Are there RoHS compliance considerations for substitution?

A: The original LP2980IM5-4.7 is RoHS non-compliant. Both substitute parts (LP2980AIM5-4.7/NOPB and LP2980IM5-4.7/NOPB) are ROHS3 compliant, meeting current environmental standards.

Q: What is the operating temperature range for these parts?

A: All three parts operate across -40°C to 125°C, supporting industrial and extended temperature applications.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the selected substitute meets your procurement, compliance, and packaging requirements. Electrical performance and thermal characteristics are identical across all three parts.
