SN101967DR Equivalent & Substitute Parts

Part Overview

The SN101967DR is a prototype component manufactured by Texas Instruments, currently designated as Last Time Buy status. This part is ROHS3 compliant with MSL 1 (Unlimited moisture sensitivity level). Due to its Last Time Buy status, identifying qualified substitute components is essential for design continuity and long-term supply chain management. The primary manufacturer-recommended substitute is the LM2903QDRQ1, an active general-purpose comparator that maintains functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN101967DR is based on the following criteria derived from provided parameters:

Compliance Requirements:

• RoHS3 compliance maintained
• MSL 1 (Unlimited) rating preserved
• Automotive-grade qualification (AEC-Q100) available in substitute

Functional Category:

• General-purpose comparator classification
• Texas Instruments manufacturer continuity
• Active product status for long-term availability

Electrical Compatibility:

• Supply voltage range: 2V ~ 36V (single), ±1V ~ 18V (dual)
• Input offset voltage: 7mV maximum @ 5V
• Output type: Open-Collector, Rail-to-Rail configuration
• Operating temperature range: -40°C ~ 125°C

The LM2903QDRQ1 meets all substitution criteria as an active, ROHS3-compliant component with identical compliance certifications and extended supply availability.

Parameter Comparison

Engineering Selection Recommendations

For Immediate Requirements: The SN101967DR remains available with 734 pieces in current inventory. This component maintains ROHS3 compliance and MSL 1 rating suitable for applications with unlimited moisture sensitivity requirements.

For Long-Term Design Continuity: The LM2903QDRQ1 is the manufacturer-recommended substitute. As an active product with 42,700 pieces in inventory, it provides extended supply assurance beyond the Last Time Buy window of the SN101967DR. Both components share identical RoHS3 and MSL 1 compliance certifications.

Qualification Advantage: The LM2903QDRQ1 carries AEC-Q100 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components or equivalent reliability standards.

Compliance Continuity: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance across design transitions.

Frequently Asked Questions (FAQ)

Q: Why is the SN101967DR designated Last Time Buy? A: Last Time Buy status indicates the manufacturer is discontinuing this part number. Existing inventory (734 pieces) represents the final available stock. The LM2903QDRQ1 is the active replacement.

Q: Are the SN101967DR and LM2903QDRQ1 pin-compatible? A: Both components are manufactured by Texas Instruments with identical compliance ratings (ROHS3, MSL 1). The LM2903QDRQ1 is specified in 8-SOIC package. Verify package specifications for your application before substitution.

Q: What is the difference in supply voltage capability? A: The LM2903QDRQ1 operates across 2V ~ 36V (single supply) or ±1V ~ 18V (dual supply) with maximum input offset voltage of 7mV @ 5V. Confirm your application voltage requirements match this range.

Q: Does the substitute maintain the same moisture sensitivity level? A: Yes. Both the SN101967DR and LM2903QDRQ1 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Is the LM2903QDRQ1 suitable for automotive applications? A: The LM2903QDRQ1 carries AEC-Q100 automotive qualification. The SN101967DR qualification status is not specified in available data.

Q: What is the operating temperature range for the substitute? A: The LM2903QDRQ1 operates from -40°C to 125°C, covering industrial and automotive temperature requirements.
