Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3054ASD is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: CANbus full-duplex transceiver functionality
• Electrical Specifications: 1/1 driver/receiver configuration, 250 kbps data rate, 18 mV receiver hysteresis, 4.75V ~ 5.25V supply voltage range
• Thermal Performance: -40°C ~ 125°C operating temperature range
• Physical Form Factor: 14-SOIC surface mount package with 0.154" (3.90mm) width
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating

The MAX3054ASD+ qualifies as a parametric equivalent substitute based on identical electrical, thermal, and mechanical specifications. The primary distinction is product status: the original part is obsolete while the substitute remains in active production.

Parameter Comparison

Engineering Selection Recommendations

The MAX3054ASD+ is the direct parametric equivalent for the obsolete MAX3054ASD. Both components share identical electrical, thermal, and mechanical specifications, ensuring pin-for-pin and functional compatibility in existing circuit designs.

Selection between these parts is determined by availability and product lifecycle status:

• MAX3054ASD: Obsolete status; use only for legacy system repairs or when existing inventory is available
• MAX3054ASD+: Active production status; recommended for new designs, production restarts, and long-term supply chain continuity

Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory and environmental requirements. The substitute part offers superior supply chain reliability due to active manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can MAX3054ASD+ be used as a direct replacement for MAX3054ASD in existing designs?

A: Yes. The MAX3054ASD+ is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required for substitution.

Q: What is the difference between MAX3054ASD and MAX3054ASD+?
