LP3470M5X-4.38 Equivalent & Substitute Parts

Part Overview

The LP3470M5X-4.38 is a single-channel supervisor IC manufactured by Texas Instruments, designed for power management and reset control applications. This device operates as a Simple Reset/Power-On Reset supervisor with an open drain or open collector output configuration. The part is classified as Obsolete, which necessitates identification of functionally equivalent alternatives for ongoing production and maintenance applications. The supervisor monitors a single voltage threshold at 4.38V with an active low reset output and 1ms minimum reset timeout.

Substitute Part Grouping Explanation

Substitution of the LP3470M5X-4.38 is determined by strict equivalence across the following critical parameters:

• Voltage Threshold: 4.38V (exact match required)
• Supervisor Type: Simple Reset/Power-On Reset with single channel monitoring
• Output Configuration: Open Drain or Open Collector
• Reset Logic: Active Low
• Reset Timeout: 1ms Minimum
• Package / Case: SC-74A, SOT-753 (SOT-23-5)
• Operating Temperature Range: -20°C ~ 85°C (TJ)
• Mounting Type: Surface Mount

The LP3470M5-4.38/NOPB qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format (Tape & Reel versus bulk) and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The LP3470M5-4.38/NOPB is the direct equivalent substitute for the LP3470M5X-4.38. Both parts maintain identical electrical and mechanical specifications, including voltage threshold, output configuration, reset timing, and package format. The substitute part carries ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part.

The primary distinction between the two parts is product lifecycle status: the main part is classified as Obsolete, while the substitute is classified as Not For New Designs. For applications requiring this specific 4.38V threshold supervisor with active low reset output in SOT-23-5 packaging, the LP3470M5-4.38/NOPB provides functional and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LP3470M5-4.38/NOPB be used as a direct replacement for the LP3470M5X-4.38?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including voltage threshold (4.38V), output configuration (open drain/open collector), reset logic (active low), and package format (SOT-23-5). The parts are pin-compatible and functionally equivalent.

Q: What is the difference between LP3470M5X-4.38 and LP3470M5-4.38/NOPB?

A: The primary difference is packaging format. The LP3470M5X-4.38 is supplied in bulk packaging, while the LP3470M5-4.38/NOPB is supplied in Tape & Reel (TR) format. Electrical specifications and mechanical dimensions are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the LP3470M5X-4.38 and LP3470M5-4.38/NOPB are ROHS3 compliant and REACH unaffected.

Q: What does the 4.38V threshold specification mean?

A: The 4.38V threshold indicates the voltage level at which the supervisor monitors the power supply. When the monitored voltage falls below this threshold, the device asserts an active low reset output signal.

Q: Is the SOT-23-5 package suitable for automated assembly?

A: Yes. The SOT-23-5 package is a standard surface mount package designed for automated pick-and-place assembly and reflow soldering processes.
