Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCA9541D/01,118 is determined by strict alignment with the following critical parameters:

• Interface Protocol: I2C and SMBus compatibility
• Channel Configuration: 2-Channel multiplexing capability
• Supply Voltage Range: 2.3V to 5.5V operation
• Package Type: 16-SOIC (0.154", 3.90mm Width) surface mount
• Electrical Compliance: ROHS3 compliance and REACH unaffected status
• Functional Classification: I2C Multiplexer Interface

The substitute part PCA9541AD/01,118 meets all specified parameters and maintains functional equivalence with the original component.

Parameter Comparison

Engineering Selection Recommendations

The PCA9541AD/01,118 serves as a direct functional substitute for the PCA9541D/01,118. Both components are manufactured by NXP, share identical electrical specifications, and are housed in the same 16-SOIC package format.

The primary distinction is product status: the PCA9541D/01,118 is classified as Obsolete, while the PCA9541AD/01,118 maintains Active status. This status difference reflects manufacturing lifecycle positioning rather than functional capability differences.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current applications. The substitute part is suitable for new designs, production continuity, and replacement applications where the original component is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can the PCA9541AD/01,118 be used as a direct replacement for the PCA9541D/01,118?

A: Yes. Both components share identical electrical specifications, interface protocols, supply voltage range, and package configuration. The PCA9541AD/01,118 is functionally equivalent and pin-compatible.

Q: What is the significance of the Obsolete status on the PCA9541D/01,118?

A: Obsolete status indicates the component is no longer in active production. The PCA9541AD/01,118, with Active status, represents the current manufacturing equivalent and is the recommended selection for ongoing applications.

Q: Are there any compliance differences between these parts?

A: No. Both components maintain identical ROHS3 compliance, REACH unaffected status, and ECCN/HTSUS classifications.

Q: Is the 16-SOIC package identical between both parts?

A: Yes. Both components use the 16-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout and mechanical dimensions.

Q: What supply voltage range do these components support?

A: Both the PCA9541D/01,118 and PCA9541AD/01,118 operate across a supply voltage range of 2.3V to 5.5V.
