Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS3840DL44DBVR is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Single voltage channel monitoring
• 4.4V threshold voltage
• Open-drain or open-collector output configuration
• Active-low reset logic
• 619ms typical reset timeout
• Operating temperature range: -40°C to 125°C

Mechanical Parameters (Must Match Exactly):

• Package type: SC-74A, SOT-753
• Supplier device package: SOT-23-5
• Surface mount mounting type
• Tape & Reel packaging format

Compliance Parameters:

• ROHS3 compliance
• REACH unaffected status
• MSL Level 1 (unlimited moisture sensitivity)

The TPS3840DL44DBVRQ1 qualifies as a parametric equivalent because it maintains all electrical and mechanical specifications while adding automotive-grade qualification (AEC-Q100). This distinction allows the Q1 variant to serve applications with automotive requirements while remaining functionally interchangeable in industrial applications.

Parameter Comparison

Engineering Selection Recommendations

TPS3840DL44DBVR Selection Criteria:

• Industrial applications without automotive qualification requirements
• Standard commercial temperature and reliability specifications
• Applications where AEC-Q100 certification is not mandated
• Current inventory availability: 2701 units

TPS3840DL44DBVRQ1 Selection Criteria:

• Automotive applications requiring AEC-Q100 qualification
• Designs subject to automotive industry standards and supplier requirements
• Applications requiring automotive-grade component traceability
• Current inventory availability: 2449 units

Both parts maintain identical electrical performance, package specifications, and compliance certifications. The selection between these two variants depends solely on application grade requirements and qualification mandates, not on functional or mechanical differences.

Frequently Asked Questions (FAQ)

Q: Can TPS3840DL44DBVRQ1 be used as a direct replacement for TPS3840DL44DBVR in industrial applications?

A: Yes. The TPS3840DL44DBVRQ1 maintains all electrical and mechanical parameters required for industrial applications. The automotive qualification (AEC-Q100) is an additional certification that does not restrict use in non-automotive designs.

Q: What is the difference between these two part numbers?

A: The TPS3840DL44DBVRQ1 carries automotive-grade qualification (AEC-Q100) and is designated for automotive applications. The TPS3840DL44DBVR is the industrial-grade variant. All electrical specifications, package types, and compliance certifications are identical.

Q: Are the package dimensions identical between TPS3840DL44DBVR and TPS3840DL44DBVRQ1?

A: Yes. Both parts use the SC-74A, SOT-753 package with SOT-23-5 supplier device package designation. PCB footprints and assembly processes are identical.
