Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP2980AIM5X-4.7 are identified based on strict electrical and mechanical parameter matching within the LP2980 series. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Output voltage: 4.7V fixed
• Output current capability: 50mA
• Maximum input voltage: 16V
• Dropout voltage: 0.22V @ 50mA
• Quiescent current: 95 µA
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Operating temperature range: -40°C ~ 125°C
• Protection features: Over-current, over-temperature, short-circuit

Substitute parts must maintain identical electrical specifications and physical packaging to ensure direct functional replacement in existing circuit designs.

Parameter Comparison

Engineering Selection Recommendations

LP2980AIM5-4.7/NOPB is the primary recommended substitute. This part maintains identical electrical specifications and physical packaging while offering Active product status and ROHS3 compliance. The Tape & Reel packaging format supports high-volume manufacturing and automated assembly processes.

LP2980IM5-4.7/NOPB provides an alternative substitute with equivalent electrical and mechanical parameters. This part is classified as Obsolete but carries ROHS3 compliance. The Cut Tape and Digi-Reel packaging format is suitable for lower-volume or manual assembly applications.

Both substitute parts are direct functional replacements for the LP2980AIM5X-4.7 based on matching electrical specifications, package type, and operating characteristics. Selection between substitutes should be based on procurement availability, packaging requirements, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can LP2980AIM5-4.7/NOPB be used as a direct replacement for LP2980AIM5X-4.7?

A: Yes. Both parts share identical electrical specifications including 4.7V fixed output, 50mA output current, 0.22V dropout voltage, and SOT-23-5 packaging. The primary difference is product status (Active vs. Obsolete) and RoHS compliance level.

Q: What is the difference between the two substitute parts?

A: LP2980AIM5-4.7/NOPB and LP2980IM5-4.7/NOPB are electrically identical. The differences are packaging format (Tape & Reel vs. Cut Tape/Digi-Reel) and product status (Active vs. Obsolete). Selection depends on procurement volume and assembly process requirements.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist for direct substitution. All three parts maintain identical electrical performance, protection features, and physical package dimensions (SOT-23-5). Pin configuration and functional behavior are equivalent.

Q: Does RoHS compliance affect substitution decisions?

A: RoHS compliance is a regulatory and procurement consideration. LP2980AIM5-4.7/NOPB and LP2980IM5-4.7/NOPB are ROHS3 compliant, while the original LP2980AIM5X-4.7 is non-compliant. For applications requiring RoHS compliance, either substitute part is appropriate.

Q: Which substitute should be selected for new designs?

A: LP2980AIM5-4.7/NOPB is recommended for new designs due to Active product status, ensuring long-term availability and supply chain stability. This part also supports standard Tape & Reel packaging for automated manufacturing.
