LP3470IM5-2.63 Equivalent & Substitute Parts

Part Overview

The LP3470IM5-2.63 is a single-channel supervisor IC from Texas Instruments designed for power management and reset control applications. This component monitors a 2.63V threshold voltage and provides active-low reset output via open drain or open collector configuration. The part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The supervisor operates across the industrial temperature range of -40°C to 85°C and is packaged in the compact SOT-23-5 surface mount form factor.

Substitute Part Grouping Explanation

Substitution for the LP3470IM5-2.63 is determined by strict equivalence across the following critical parameters:

• Voltage Threshold: 2.63V (exact match required)
• Number of Channels: 1 channel
• Output Type: Open Drain or Open Collector
• Reset Logic: Active Low
• Reset Timeout: 1ms Minimum
• Package: SOT-23-5 (SC-74A, SOT-753)
• Operating Temperature Range: -40°C to 85°C minimum
• Mounting Type: Surface Mount

The identified substitute LP3470IM5-2.63/NOPB maintains identical electrical specifications and physical packaging, differing only in packaging format (Tape & Reel versus bulk) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The LP3470IM5-2.63/NOPB serves as the direct equivalent substitute for the obsolete LP3470IM5-2.63. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The primary distinction lies in product status and regulatory compliance: the substitute carries ROHS3 compliance status, whereas the original is RoHS non-compliant. For applications requiring regulatory compliance with modern environmental standards, the LP3470IM5-2.63/NOPB is the appropriate selection. The packaging format difference (Tape & Reel for the substitute versus unspecified for the original) does not affect electrical performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can LP3470IM5-2.63/NOPB be used as a direct replacement for LP3470IM5-2.63?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage thresholds (2.63V), output configurations (open drain/open collector), reset logic (active low), and SOT-23-5 packaging. The substitute is functionally interchangeable at the circuit level.

Q: What is the significance of the "/NOPB" suffix?

A: The "/NOPB" designation indicates the part is supplied in Tape & Reel packaging format without plating on the leads. This is a packaging and delivery specification that does not affect electrical performance or compatibility.

Q: Does the RoHS compliance difference impact circuit functionality?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or functional characteristics. Both parts operate identically within the specified parameters.

Q: Are there any temperature or threshold voltage differences between these parts?

A: No. Both parts operate across -40°C to 85°C and monitor the identical 2.63V threshold voltage. All timing and electrical specifications are equivalent.

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Yes, provided the assembly process accommodates the Tape & Reel packaging format of the substitute. The SOT-23-5 footprint and pin configuration are identical, allowing direct substitution in pick-and-place operations.
