Substitute Part Grouping Explanation

Substitution for the LP2980IM5X-4.7 is determined by strict electrical and mechanical parameter matching:

Critical Substitution Parameters:

• Fixed output voltage: 4.7V
• Output current capability: 50mA
• Maximum input voltage: 16V
• Dropout voltage: 0.22V @ 50mA
• Package: SOT-23-5
• Surface Mount configuration
• Operating temperature range: -40°C to 125°C
• Protection features: Over Current, Over Temperature, Short Circuit
• Control feature: Enable

The identified substitutes maintain identical electrical specifications and mechanical compatibility. Variations exist only in product status and packaging format (Tape & Reel versus Cut Tape & Digi-Reel).

Parameter Comparison

Engineering Selection Recommendations

LP2980AIM5-4.7/NOPB is the primary substitute for new designs and procurement. This part maintains full electrical and mechanical compatibility while offering Active product status and ROHS3 compliance. The Tape & Reel packaging format supports automated assembly processes.

LP2980IM5-4.7/NOPB provides an alternative substitute with identical electrical specifications and ROHS3 compliance. Product status is Obsolete, matching the original part. Cut Tape & Digi-Reel packaging accommodates lower-volume or manual assembly requirements.

Selection between substitutes should prioritize LP2980AIM5-4.7/NOPB for long-term design support and regulatory compliance. LP2980IM5-4.7/NOPB remains viable where existing procurement channels or assembly methods require Cut Tape format.

Frequently Asked Questions (FAQ)

Q: Can LP2980AIM5-4.7/NOPB directly replace LP2980IM5X-4.7 in existing designs?

A: Yes. Both parts deliver identical electrical performance: 4.7V fixed output, 50mA current, 0.22V dropout voltage, and operate across -40°C to 125°C. The SOT-23-5 package is mechanically identical. The primary difference is product status (Active versus Obsolete) and RoHS compliance level.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging (LP2980AIM5-4.7/NOPB) is optimized for high-volume automated assembly. Cut Tape & Digi-Reel (LP2980IM5-4.7/NOPB) supports lower-volume or manual pick-and-place operations. Electrical performance is identical.

Q: Why is RoHS compliance relevant for this substitution?

A: LP2980AIM5-4.7/NOPB carries ROHS3 compliance, meeting current environmental and regulatory standards. The original LP2980IM5X-4.7 is RoHS non-compliant. For new designs or regulated applications, ROHS3-compliant substitutes are preferred.

Q: Are there any thermal or performance differences between these parts?

A: No. All three parts share identical thermal characteristics, quiescent current (95 µA), PSRR (63dB at 1kHz), and protection features (Over Current, Over Temperature, Short Circuit).

Q: Can I use these substitutes interchangeably on the same PCB?

A: Yes. The SOT-23-5 package footprint is standardized across all three parts. No PCB redesign is required for substitution.
