Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS75451MX is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 8-SOIC (0.154", 3.90mm Width) surface mount package to ensure PCB layout compatibility without redesign.
• Electrical Specifications: Supply voltage range of 4.75V to 5.25V and operating temperature range of 0°C to 70°C must be maintained.
• Functional Classification: The substitute must be a peripheral driver or equivalent interface driver with matching driver/receiver configuration (2/0).
• Base Product Number Alignment: The SN75451BDR shares the same base product number (SN75451/DS75451 family), confirming functional equivalence within the Texas Instruments driver product line.

The SN75451BDR qualifies as a direct substitute based on these parameters.

Engineering Selection Recommendations

The SN75451BDR is the appropriate substitute for the obsolete DS75451MX based on the following factors:

• Product Status: The SN75451BDR is currently in active production status, ensuring long-term availability and supply chain reliability compared to the obsolete DS75451MX.
• Compliance Improvement: The SN75451BDR achieves ROHS3 compliance, addressing regulatory requirements that the non-compliant DS75451MX does not meet.
• Electrical Equivalence: Both components maintain identical supply voltage (4.75V ~ 5.25V) and operating temperature ranges (0°C ~ 70°C), ensuring functional compatibility in existing circuit designs.
• Package Compatibility: The 8-SOIC package specification is identical, eliminating the need for PCB layout modifications.
• Certification Alignment: Both components share identical REACH and ECCN classifications, maintaining regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the SN75451BDR be used as a direct replacement for the DS75451MX without PCB modifications?

A: Yes. Both components use the identical 8-SOIC (0.154", 3.90mm Width) surface mount package, enabling direct pin-for-pin substitution without PCB redesign.

Q: Are the electrical specifications identical between DS75451MX and SN75451BDR?

A: The supply voltage range (4.75V ~ 5.25V) and operating temperature range (0°C ~ 70°C) are identical. The SN75451BDR specifies an open collector output type with 300mA output low current capability.

Q: What is the primary reason to transition from DS75451MX to SN75451BDR?

A: The DS75451MX is obsolete, creating supply chain risk. The SN75451BDR is in active production and offers ROHS3 compliance, providing regulatory alignment and long-term availability.

Q: Are there any compliance differences between these components?

A: Yes. The SN75451BDR is ROHS3 compliant, while the DS75451MX is RoHS non-compliant. Both share identical REACH and ECCN classifications.

Q: What is the moisture sensitivity level for both components?

A: Both the DS75451MX and SN75451BDR have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions.
