Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP3470IM5-3.65 is determined by strict equivalence across the following critical parameters:

• Single-channel voltage monitoring capability
• 3.65V threshold voltage specification
• Open drain or open collector output configuration
• Active low reset logic
• 1ms minimum reset timeout
• SOT-23-5 package compatibility
• Surface mount technology
• Operating temperature range of -40°C to 85°C

The LP3470IM5-3.65/NOPB variant meets all these criteria and qualifies as a direct substitute. Both parts share identical electrical specifications, package dimensions, and pinout configuration, enabling direct board-level replacement without circuit modification.

Parameter Comparison

Engineering Selection Recommendations

The LP3470IM5-3.65/NOPB is the direct functional equivalent for the obsolete LP3470IM5-3.65. Both parts deliver identical electrical performance and physical compatibility for board-level integration.

The LP3470IM5-3.65/NOPB offers improved compliance status with ROHS3 certification, compared to the RoHS non-compliant status of the original part. This compliance advantage makes the /NOPB variant the preferred selection for applications subject to RoHS regulatory requirements.

Both parts maintain equivalent REACH unaffected status and identical ECCN and HTSUS classifications, ensuring consistent regulatory treatment across supply chain operations.

Frequently Asked Questions (FAQ)

Q: Can LP3470IM5-3.65/NOPB replace LP3470IM5-3.65 without circuit modification?

A: Yes. Both parts are electrically and mechanically identical with matching pinout, voltage threshold, output configuration, and package dimensions. Direct substitution is possible without design changes.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB designation indicates lead-free, halogen-free packaging that meets ROHS3 compliance requirements. The electrical specifications remain unchanged from the base part number.

Q: Are there differences in operating temperature performance?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C (TJ).

Q: What is the moisture sensitivity level for these parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical SOT-23-5 package, pinout, and electrical specifications enable direct board-level interchange without PCB redesign.

Q: What compliance certifications apply to both parts?

A: Both parts maintain REACH unaffected status. The LP3470IM5-3.65/NOPB additionally provides ROHS3 compliance, while the original LP3470IM5-3.65 is RoHS non-compliant.
