Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74CBTLV3126D is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: 1 x 1:1
• Independent circuits: 4
• Voltage supply range: 2.3V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Package type: 14-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical requirements, ensuring functional and physical compatibility within the specified design constraints.

Parameter Comparison

Engineering Selection Recommendations

SN74CBTLV3126DR is the manufacturer-recommended substitute. This part maintains identical electrical specifications and package configuration while offering Active product status and significantly higher inventory availability (13956 units). The primary distinction is packaging format: Tape & Reel (TR) versus Tube. This variant is suitable for high-volume production environments where continuous reel feeding is standard.

SN74CBTLV3125D qualifies as a parametric equivalent, meeting all electrical and mechanical requirements. This part is available in Tube packaging, matching the original SN74CBTLV3126D format. However, it carries Last Time Buy status similar to the main part. Selection of this alternative should be evaluated based on specific packaging requirements and procurement timelines.

Both substitutes carry ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility with the original specification.

Frequently Asked Questions (FAQ)

Q: Can SN74CBTLV3126DR be used as a direct replacement for SN74CBTLV3126D?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: SN74CBTLV3126DR uses Tape & Reel (TR) while SN74CBTLV3126D uses Tube. Selection depends on your assembly process requirements.

Q: What is the difference between SN74CBTLV3126D and SN74CBTLV3125D?

A: Both parts share identical electrical specifications, circuit configuration, voltage supply range, operating temperature, and package type. The base product numbers differ (3126 versus 3125), but functional parameters remain equivalent for substitution purposes.

Q: Why is SN74CBTLV3126DR recommended over other alternatives?

A: SN74CBTLV3126DR holds Active product status and maintains the highest inventory availability (13956 units), providing superior long-term supply assurance compared to Last Time Buy alternatives.

Q: Are all three parts RoHS compliant?

A: Yes. SN74CBTLV3126D, SN74CBTLV3126DR, and SN74CBTLV3125D are all ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited).

Q: Does packaging format affect electrical performance?

A: No. Tube and Tape & Reel packaging formats contain identical components. Selection is based on manufacturing process compatibility and procurement logistics, not electrical characteristics.
