Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX6954APL is determined by strict equivalence across the following critical parameters:

• Display configuration (7, 14, 16 segment types and common cathode topology)
• Serial interface protocol (4-wire serial communication)
• Digit/character capacity (8 or 16 digits)
• Supply voltage range (2.7V ~ 5.5V)
• Supply current specification (22 mA)
• Operating temperature range (-40°C ~ 125°C)
• Physical package format (40-DIP, 0.600" pitch, 15.24mm)
• Mounting technology (Through Hole)

The MAX6954APL+ qualifies as a direct substitute based on identical electrical specifications, mechanical compatibility, and functional equivalence across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

The MAX6954APL+ is the direct substitute for the obsolete MAX6954APL. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility in existing circuit designs. The primary distinction is product lifecycle status: the MAX6954APL is obsolete, while the MAX6954APL+ maintains active production status with current availability.

The MAX6954APL+ additionally achieves ROHS3 compliance, meeting modern regulatory requirements for new designs and manufacturing environments. Both parts maintain identical moisture sensitivity classification (MSL 1), REACH unaffected status, and export control classification (EAR99), ensuring equivalent handling and logistics requirements.

For applications requiring the MAX6954 LED driver functionality, the MAX6954APL+ is the appropriate selection for new production, as it provides equivalent performance with active supply chain support and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the MAX6954APL+ be used as a direct replacement for the MAX6954APL in existing designs?

A: Yes. The MAX6954APL+ is electrically and mechanically identical to the MAX6954APL. All electrical parameters, pin configurations, package dimensions, and functional specifications are equivalent. No circuit modifications are required for substitution.

Q: What is the primary reason to transition from MAX6954APL to MAX6954APL+?

A: The MAX6954APL is classified as obsolete product status, indicating discontinued manufacturing and declining component availability. The MAX6954APL+ maintains active production status, ensuring reliable supply chain access for current and future production requirements.

Q: Are there any compliance differences between these parts?
