Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP3470IM5-4.00 is determined by strict alignment of the following electrical and mechanical parameters:

• Single-channel voltage monitoring capability
• 4V voltage threshold setting
• Open drain or open collector output configuration
• Active low reset signal polarity
• SOT-23-5 package compatibility
• Surface mount mounting type
• ROHS3 compliance and REACH unaffected status

The substitute parts identified maintain these core parameters while differing in product status, packaging format (Cut Tape vs. Tape & Reel), and in one case, extended operating temperature range and reset timeout characteristics.

Parameter Comparison

Engineering Selection Recommendations

LP3470IM5-4.00/NOPB serves as a direct equivalent substitute, maintaining identical electrical specifications and operating temperature range while differing only in packaging format (Tape & Reel versus Cut Tape). This part is suitable for existing designs requiring component replacement, though it carries a "Not For New Designs" status.

LP3470A400DBVR is the manufacturer-recommended active substitute. This part maintains all core electrical parameters and package compatibility while offering an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C) and different reset timeout characteristics (619ms typical versus 1ms minimum). The Active product status makes this the preferred choice for new designs and long-term system support. The higher inventory availability (3483 units) provides supply chain stability.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can LP3470IM5-4.00/NOPB be used as a direct replacement for LP3470IM5-4.00?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: LP3470IM5-4.00 is supplied in Cut Tape format, while LP3470IM5-4.00/NOPB is supplied in Tape & Reel format. Selection depends on procurement and assembly requirements.

Q: What is the primary difference between LP3470IM5-4.00 and LP3470A400DBVR?

A: The LP3470A400DBVR offers an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C) and different reset timeout characteristics (619ms typical versus 1ms minimum). All other electrical and mechanical parameters remain identical. The LP3470A400DBVR is the active product recommended for new designs.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the SOT-23-5 package (SC-74A, SOT-753 case), ensuring identical PCB footprint and mounting compatibility.

Q: Why is the LP3470IM5-4.00 marked as Obsolete?

A: The original part has reached end-of-life status. Texas Instruments recommends using LP3470A400DBVR for new designs and ongoing system support.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment across substitution options.
