LP3470IM5X-4.38 Equivalent & Substitute Parts

Part Overview

The LP3470IM5X-4.38 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 4.38V and provides an active-low open drain output. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP3470IM5X-4.38 are identified based on strict parametric equivalence across the following critical criteria:

• Single voltage monitoring channel
• 4.38V threshold voltage
• Active-low reset output (open drain or open collector)
• 1ms minimum reset timeout
• Operating temperature range of -40°C to 85°C
• SOT-23-5 surface mount package
• SC-74A / SOT-753 case designation

The identified substitutes maintain functional and electrical compatibility within these defined parameters. Differences in product status and RoHS compliance are noted but do not affect electrical substitutability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LP3470IM5X-4.38, LP3470IM5-4.38, and LP3470IM5-4.38/NOPB—are electrically and functionally equivalent for applications requiring a single-channel 4.38V supervisor with active-low reset output in SOT-23-5 packaging.

For legacy system support and field replacements, LP3470IM5-4.38 and LP3470IM5-4.38/NOPB are preferred alternatives due to ROHS3 compliance status. LP3470IM5-4.38/NOPB is supplied in Tape & Reel format, suitable for automated assembly processes.

The original LP3470IM5X-4.38 remains functionally compatible but carries obsolete status and RoHS non-compliant designation. Selection should prioritize compliance requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can LP3470IM5-4.38 directly replace LP3470IM5X-4.38 in existing designs?

A: Yes. Both parts share identical electrical specifications: single-channel voltage monitoring at 4.38V, active-low reset output, 1ms minimum reset timeout, and SOT-23-5 surface mount packaging. No circuit modifications are required.

Q: What is the difference between LP3470IM5-4.38 and LP3470IM5-4.38/NOPB?

A: The primary difference is packaging format. LP3470IM5-4.38/NOPB is supplied in Tape & Reel (TR) format for automated pick-and-place assembly, while LP3470IM5-4.38 uses standard packaging. Electrical performance is identical.

Q: Why is the original part marked as obsolete?

A: Product obsolescence is determined by the manufacturer and typically reflects end-of-life status. Functionally equivalent alternatives with current product status are available.

Q: Are there RoHS compliance differences between these parts?

A: Yes. LP3470IM5X-4.38 is RoHS non-compliant, while LP3470IM5-4.38 and LP3470IM5-4.38/NOPB are ROHS3 compliant. For applications subject to RoHS regulations, the compliant variants are required.

Q: Will the SOT-23-5 package fit existing PCB layouts designed for LP3470IM5X-4.38?

A: Yes. All three parts use identical SOT-23-5 surface mount packaging (SC-74A, SOT-753 case designation), ensuring mechanical and electrical compatibility with existing PCB designs.

Q: What is the inventory status of these parts?

A: LP3470IM5X-4.38 has 20,400 units in stock. LP3470IM5-4.38 has 5,425 units. LP3470IM5-4.38/NOPB has 2,138 units available as new original stock.
