Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDC203DWR is determined by strict equivalence across the following critical parameters:

• Logic configuration: 6-channel inverter with single input per channel
• Electrical specifications: 3V to 3.6V supply voltage, 4 µA maximum quiescent current, 12mA output drive capability, and 6.1ns propagation delay at 3.3V with 30pF load
• Input/output logic levels: Low input 0.9V–1.1V, high input 2.1V–2.5V
• Physical packaging: 20-SOIC surface mount form factor with 0.295" width (7.50mm)
• Environmental compliance: ROHS3 compliance and MSL Level 1 rating

The CDC203DW qualifies as a direct substitute based on identical electrical and mechanical specifications. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The CDC203DW is the direct equivalent substitute for the CDC203DWR. Both components share identical electrical characteristics, logic configuration, and physical packaging specifications. The CDC203DW holds active product status from Texas Instruments, ensuring continued availability and manufacturing support compared to the obsolete CDC203DWR.

Both parts maintain ROHS3 compliance and MSL Level 1 rating, confirming equivalent environmental and handling requirements. Selection between these parts should be based on procurement availability and supply chain considerations, as electrical and mechanical compatibility is complete.

Frequently Asked Questions (FAQ)

Q: Can CDC203DW replace CDC203DWR in existing designs? A: Yes. The CDC203DW is electrically and mechanically equivalent to the CDC203DWR. All electrical parameters, logic levels, propagation delay, output drive capability, and package dimensions are identical. Direct substitution is supported without design modification.

Q: What is the difference between CDC203DWR and CDC203DW? A: The primary difference is product status and packaging format. The CDC203DWR is obsolete and supplied in tape reel packaging (DWR designation), while the CDC203DW is active and supplied in tube packaging (DW designation). Electrical specifications and 20-SOIC package dimensions are identical.

Q: Are there any compliance or certification differences? A: No. Both CDC203DWR and CDC203DW maintain ROHS3 compliance and MSL Level 1 rating. Environmental and regulatory certifications are equivalent.

Q: What supply voltage range is supported? A: Both parts operate within a 3V to 3.6V supply voltage range. Input logic levels are 0.9V–1.1V for low state and 2.1V–2.5V for high state.

Q: What is the propagation delay specification? A: Maximum propagation delay is 6.1 nanoseconds at 3.3V supply voltage with a 30pF load capacitance for both parts.

Q: Are package dimensions identical? A: Yes. Both parts use the 20-SOIC surface mount package with 0.295" width (7.50mm). PCB footprints and assembly requirements are identical.
