Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75372D is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Driven configuration (Low-Side)
• Channel type (Synchronous)
• Number of drivers (2)
• Gate type (N-Channel MOSFET)
• Supply voltage range (4.75V ~ 5.25V, 4.75V ~ 24V)
• Logic voltage thresholds (VIL 0.8V, VIH 2V)
• Peak output current (500mA source, 500mA sink)
• Input type (Inverting)
• Rise/fall time (20ns typical)
• Operating temperature range (0°C ~ 70°C)

Mechanical Equivalence Criteria:

• Package type (8-SOIC)
• Package dimensions (0.154", 3.90mm Width)
• Mounting type (Surface Mount)

Compliance Equivalence Criteria:

• RoHS3 compliance
• MSL rating (1 - Unlimited)

The SN75372DR qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is packaging format: the SN75372D is supplied in Tube packaging, while the SN75372DR is supplied in Tape & Reel (TR) format. Both parts share the same base product number (SN75372) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The SN75372DR is a direct electrical and mechanical equivalent to the SN75372D. Both parts are manufactured by Texas Instruments and meet identical ROHS3 compliance and MSL requirements. The SN75372D is designated Last Time Buy, indicating limited future availability. The SN75372DR maintains Active product status, ensuring continued supply and support.

Selection between these parts is determined by packaging requirements and supply chain logistics. The SN75372D in Tube packaging is suitable for lower-volume applications or manual assembly processes. The SN75372DR in Tape & Reel format is optimized for high-volume automated assembly operations and provides superior supply chain continuity.

Both parts are pin-compatible, functionally identical, and suitable for direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the SN75372DR replace the SN75372D in existing designs?

A: Yes. The SN75372DR is electrically and mechanically equivalent to the SN75372D. Both parts feature identical gate driver specifications, supply voltage ranges, output current ratings, and timing characteristics. Direct substitution is possible without circuit redesign.

Q: What is the difference between SN75372D and SN75372DR?

A: The primary difference is packaging format. The SN75372D is supplied in Tube packaging, while the SN75372DR is supplied in Tape & Reel (TR) format. All electrical and mechanical specifications are identical. Tape & Reel packaging is standard for high-volume manufacturing and automated assembly.

Q: Why is the SN75372D marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory may be available, but future supply cannot be guaranteed. The SN75372DR, with Active product status, represents the recommended long-term supply source.

Q: Are there any pin compatibility concerns when substituting SN75372DR for SN75372D?

A: No. Both parts use the 8-SOIC package with identical pinout and electrical characteristics. Pin-for-pin substitution is supported without modification to PCB layout or schematic design.

Q: What compliance certifications apply to both parts?

A: Both the SN75372D and SN75372DR are ROHS3 compliant and carry MSL rating 1 (Unlimited moisture sensitivity level). Both parts meet REACH requirements and are classified under ECCN EAR99.
