Substitute Part Grouping Explanation

Substitution eligibility for the CD4042BDWR is determined by strict equivalence across the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Independent Circuits: 4 channels
• Output Type: Differential
• Voltage - Supply Range: 3V ~ 18V
• Propagation Delay Time: 40ns
• Output Current Capability: 6.8mA (High and Low)
• Operating Temperature Range: -55°C ~ 125°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The CD4042BDW qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is product status and packaging format, with CD4042BDW maintaining Active status and Tube packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The CD4042BDW is the manufacturer-recommended substitute for the obsolete CD4042BDWR. Both parts share identical electrical specifications, functional characteristics, and physical packaging dimensions. The CD4042BDW maintains Active product status, ensuring ongoing availability and supply chain support.

Selection of CD4042BDW over CD4042BDWR is justified by:

• Identical electrical performance across all specified parameters
• Active product status providing long-term availability
• Full compliance with ROHS3 and REACH requirements
• Equivalent MSL rating and handling requirements
• Direct pin-compatible replacement in 16-SOIC package

Packaging format differs between the two parts (Reel for CD4042BDWR versus Tube for CD4042BDW). Verify packaging requirements for your procurement and assembly processes before finalizing component selection.

Frequently Asked Questions (FAQ)
