LP3470M5X-3.08 Equivalent & Substitute Parts
Part Overview
The LP3470M5X-3.08 is a single-channel supervisor integrated circuit manufactured by Texas Instruments, designed for power management and reset signal generation in electronic systems. This component operates as a simple reset/power-on reset device 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. Substitute parts maintain identical electrical and mechanical specifications while offering improved availability and compliance status.

Substitute Part Grouping Explanation
Substitute parts for the LP3470M5X-3.08 are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are:
- Identical voltage threshold: 3.08V
- Identical output configuration: Open Drain or Open Collector
- Identical reset logic: Active Low
- Identical reset timeout: 1ms Minimum
- Identical operating temperature range: -20°C ~ 85°C (TJ)
- Identical package type: SC-74A, SOT-753 (SOT-23-5)
- Identical mounting type: Surface Mount
- Identical moisture sensitivity level: MSL 1 (Unlimited)
All substitute parts listed maintain these parameters without deviation. Differences in product status, RoHS compliance, and packaging format (Tape & Reel versus Cut Tape) do not affect functional equivalence.

| LP3470M5X-3.08/NOPB | Texas Instruments | 3.08V | Open Drain/Open Collector | Active Low | 1ms Min | -20°C ~ 85°C | SOT-23-5 | Not For New Designs | ROHS3 Compliant | Tape & Reel | 9505 |
| LP3470M5-3.08 | Texas Instruments | 3.08V | Open Drain/Open Collector | Active Low | 1ms Min | -20°C ~ 85°C | SOT-23-5 | Obsolete | RoHS non-compliant | Cut Tape & Digi-Reel | 1302 |
| LP3470M5-3.08/NOPB | Texas Instruments | 3.08V | Open Drain/Open Collector | Active Low | 1ms Min | -20°C ~ 85°C | SOT-23-5 | Not For New Designs | ROHS3 Compliant | Tape & Reel | 2228 |
Engineering Selection Recommendations
Selection among equivalent parts should be based on product status and compliance requirements:
LP3470M5X-3.08/NOPB and LP3470M5-3.08/NOPB are designated "Not For New Designs" and carry ROHS3 compliance certification. These variants are suitable for applications where regulatory compliance and long-term availability are priorities.
LP3470M5X-3.08 and LP3470M5-3.08 are classified as obsolete with RoHS non-compliant status. These variants are appropriate for legacy system maintenance where compliance requirements do not apply and existing inventory is available.
Packaging format selection (Tape & Reel versus Cut Tape & Digi-Reel) depends on procurement and assembly workflow requirements and does not affect electrical performance.
Frequently Asked Questions (FAQ)
Q: Are all listed parts electrically interchangeable with the LP3470M5X-3.08?
A: Yes. All substitute parts maintain identical voltage threshold (3.08V), output configuration (Open Drain/Open Collector), reset logic (Active Low), reset timeout (1ms minimum), operating temperature range (-20°C ~ 85°C), and package type (SOT-23-5). Electrical performance is equivalent across all listed variants.
Q: What is the difference between LP3470M5X-3.08 and LP3470M5-3.08?
A: Both parts are electrically identical. The primary differences are packaging format (bulk versus Cut Tape & Digi-Reel) and inventory availability. The "X" designation in LP3470M5X-3.08 indicates a specific packaging variant.
Q: Why do some parts have the /NOPB suffix?
A: The /NOPB suffix indicates lead-free, RoHS3 compliant versions. These parts meet modern environmental and regulatory standards. Parts without this suffix are RoHS non-compliant.
Q: Can I use LP3470M5X-3.08/NOPB as a direct replacement for LP3470M5X-3.08?
A: Yes. Both parts are functionally equivalent with identical electrical specifications and package type. The /NOPB variant offers improved compliance status and is suitable for new designs and applications with regulatory requirements.
Q: What packaging formats are available?
A: Substitute parts are available in Tape & Reel (TR) format for automated assembly and Cut Tape & Digi-Reel format for manual or mixed-volume applications. Package type (SOT-23-5) remains constant across all variants.
Q: Are there any temperature or environmental differences between substitute parts?
A: No. All substitute parts operate within the identical temperature range (-20°C ~ 85°C) and maintain MSL 1 (Unlimited) moisture sensitivity rating. Environmental performance is equivalent.
