LP3470IM5X-2.63 Equivalent & Substitute Parts

Part Overview

The LP3470IM5X-2.63 is a single-channel supervisor IC in SOT-23-5 surface mount packaging, designed for power-on reset and simple reset applications. This component monitors a single voltage threshold at 2.63V and provides an active-low open drain output. The part is classified as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent or substitute parts is necessary for ongoing production support, maintenance applications, and legacy system repairs where this specific supervisor function remains required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LP3470IM5X-2.63 is determined by strict alignment of the following critical parameters:

• Voltage Threshold: Must be 2.63V
• Number of Channels: Must be single-channel (1 voltage monitored)
• Output Configuration: Must be open drain or open collector
• Reset Logic: Must be active low
• Reset Timeout: Must be 1ms minimum
• Operating Temperature Range: Must support -40°C to 85°C
• Package Type: Must be SOT-23-5 (SC-74A, SOT-753)
• Mounting Type: Must be surface mount

The identified substitute part LP3470IM5-2.63/NOPB meets all these critical parameters and is manufactured by the same supplier (Texas Instruments), ensuring functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LP3470IM5-2.63/NOPB is a direct functional and mechanical substitute for the LP3470IM5X-2.63. Both parts share identical electrical specifications, package geometry, and thermal operating range. The primary distinction is RoHS compliance status: the substitute part is ROHS3 compliant, while the main part is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, the LP3470IM5-2.63/NOPB is the appropriate selection. Both parts maintain REACH unaffected status and identical ECCN and HTSUS classifications. Current inventory availability differs, with the main part showing 6961 units and the substitute showing 1745 units in stock.

Frequently Asked Questions (FAQ)

Q: Can LP3470IM5-2.63/NOPB be used as a direct replacement for LP3470IM5X-2.63?

A: Yes. Both parts are functionally and mechanically identical. They share the same voltage threshold (2.63V), output configuration (open drain), reset logic (active low), operating temperature range (-40°C to 85°C), and SOT-23-5 package. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance. LP3470IM5-2.63/NOPB is ROHS3 compliant, while LP3470IM5X-2.63 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the SC-74A/SOT-753 package in SOT-23-5 configuration. Pinout and mechanical dimensions are identical, allowing direct PCB substitution without layout changes.

Q: Why is the main part marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. For new product development, Texas Instruments recommends evaluating current-generation supervisor ICs. However, for legacy system support and maintenance, this part remains available through authorized distributors.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical function. Both parts deliver identical performance in the specified operating conditions.

Q: What is the significance of the MSL rating?

A: Both parts carry MSL 1 (Unlimited), indicating they have unlimited shelf life and require no special moisture control during storage or handling. Standard ESD precautions apply during assembly.
