LP3470M5-2.63 Equivalent & Substitute Parts
Part Overview
The LP3470M5-2.63 is a single-channel supervisor IC in SOT-23-5 surface mount packaging, designed for power management and reset control applications. This component monitors a single voltage threshold at 2.63V and provides active-low reset output via open drain or open collector configuration with a 1ms minimum reset timeout.
The main part number LP3470M5-2.63 is classified as Obsolete, making it necessary to identify functionally equivalent alternatives for new designs and ongoing production support. The substitute part LP3470M5-2.63/NOPB provides direct functional equivalence with improved compliance status.

Substitute Part Grouping Explanation
Substitution eligibility for the LP3470M5-2.63 is determined by the following critical parameters:
- Voltage Threshold: Must be 2.63V
- Number of Voltages Monitored: Must be 1 channel
- Output Configuration: Must be Open Drain or Open Collector
- Reset Logic: Must be Active Low
- Reset Timeout: Must be 1ms Minimum
- Package / Case: Must be SC-74A, SOT-753 (SOT-23-5)
- Mounting Type: Must be Surface Mount
- Operating Temperature Range: Must support -20°C ~ 85°C (TJ)
The LP3470M5-2.63/NOPB variant meets all these criteria and serves as a direct functional equivalent. The primary difference is packaging format (Tape & Reel vs. standard packaging) and improved RoHS compliance status, with no impact on electrical performance or pin compatibility.

Engineering Selection Recommendations
The LP3470M5-2.63/NOPB is the direct substitute for LP3470M5-2.63. Both parts are electrically and mechanically identical with identical pin configurations and functional specifications.
The LP3470M5-2.63/NOPB variant offers improved compliance status (ROHS3 Compliant vs. RoHS non-compliant) and is available in Tape & Reel packaging format, which is standard for production environments. The main part number LP3470M5-2.63 is classified as Obsolete, while the substitute is classified as Not For New Designs, indicating limited future availability for both variants.
For applications requiring a supervisor IC with 2.63V threshold monitoring and active-low reset output in SOT-23-5 packaging, the LP3470M5-2.63/NOPB provides equivalent functionality with superior compliance documentation.
Frequently Asked Questions (FAQ)
Q: Can LP3470M5-2.63/NOPB be used as a direct replacement for LP3470M5-2.63?
A: Yes. Both parts are electrically and mechanically identical. The /NOPB suffix indicates Tape & Reel packaging and improved RoHS compliance status. Pin configuration, voltage threshold, reset logic, and output characteristics are identical.
Q: What does the /NOPB designation mean?
A: The /NOPB suffix indicates the part is supplied in Tape & Reel (TR) packaging format without lead-free plating. This is standard for high-volume production environments.
Q: Are there any differences in reset timeout between the two parts?
A: No. Both parts maintain a 1ms minimum reset timeout specification.
Q: Can these parts be used interchangeably on the same PCB assembly?
A: Yes. Both parts use identical SOT-23-5 (SC-74A, SOT-753) packaging with the same pin assignments and electrical characteristics.
Q: What is the significance of the RoHS compliance difference?
A: The LP3470M5-2.63/NOPB is ROHS3 Compliant, meeting current environmental and material restriction standards. The original LP3470M5-2.63 is RoHS non-compliant. For new designs and applications subject to RoHS regulations, the /NOPB variant is the appropriate selection.
Q: Are both parts still available for purchase?
A: The LP3470M5-2.63 is Obsolete. The LP3470M5-2.63/NOPB is classified as Not For New Designs, indicating limited availability. Inventory levels should be verified with component suppliers for current stock status.
Q: What is the operating temperature range for these supervisor ICs?
A: Both parts operate across -20°C to 85°C junction temperature (TJ), suitable for industrial and commercial applications.
