Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD4042BDRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: D-Type Transparent Latch
• Circuit Configuration: 1:1 (4 independent channels)
• Output Type: Differential
• Supply Voltage Range: 3V ~ 18V
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 125°C
• RoHS and REACH Compliance Status

Substitute parts are grouped into two categories based on parametric equivalence:

Category 1: Texas Instruments Direct Equivalents Parts CD4042BDR and CD4042BDT maintain identical electrical specifications to the CD4042BDRG4, including 40ns propagation delay and 6.8mA output current ratings. These parts differ only in packaging format (Tape & Reel versus bulk).

Category 2: onsemi Cross-Manufacturer Equivalents Parts MC14042BDR2G, MC14042BDG, NLV14042BDR2G, and NLV14042BDG are functionally equivalent but exhibit slightly different electrical performance characteristics. These parts operate within the same supply voltage and temperature ranges but have 60ns propagation delay and 8.8mA output current ratings. All maintain identical package geometry and pin configuration.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CD4042BDR

The CD4042BDR is the manufacturer-recommended direct substitute for CD4042BDRG4. This part maintains identical electrical specifications including 40ns propagation delay and 6.8mA output current. The CD4042BDR is currently in active production status with 27,800 units in stock, ensuring long-term availability. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings.

Secondary Recommendation: MC14042BDR2G or NLV14042BDR2G

When CD4042BDR availability is constrained, MC14042BDR2G and NLV14042BDR2G provide functional equivalence with active product status. Both onsemi parts operate within identical supply voltage and temperature ranges and maintain the same 16-SOIC package geometry. The trade-off is increased propagation delay (60ns versus 40ns) and higher output current (8.8mA versus 6.8mA). These differences are acceptable in applications where timing margins accommodate the slower propagation delay and where output current requirements do not exceed 8.8mA per channel.

Avoid: MC14042BDG and NLV14042BDG

Both parts carry obsolete product status and should not be selected for new designs or production runs.

Frequently Asked Questions (FAQ)

Q: Can CD4042BDR directly replace CD4042BDRG4 without circuit modification?

A: Yes. CD4042BDR is electrically and mechanically identical to CD4042BDRG4. Both parts share the same 16-SOIC package geometry, pin configuration, supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), and propagation delay (40ns). No circuit modifications are required.

Q: What is the difference between CD4042BDR and MC14042BDR2G?

A: Both parts are quad D-type transparent latches in 16-SOIC packaging with identical supply voltage and temperature ranges. The key differences are propagation delay (CD4042BDR: 40ns; MC14042BDR2G: 60ns) and output current (CD4042BDR: 6.8mA; MC14042BDR2G: 8.8mA). CD4042BDR is manufactured by Texas Instruments; MC14042BDR2G is manufactured by onsemi. Substitution is valid only if circuit timing requirements accommodate 60ns delay and output current requirements do not exceed 8.8mA.

Q: Why are MC14042BDG and NLV14042BDG listed if they are obsolete?

A: These parts are documented for reference purposes only. They are functionally equivalent to CD4042BDRG4 but carry obsolete product status, indicating discontinued manufacturing and limited availability. New designs should not specify these parts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (CD4042BDR, CD4042BDT, MC14042BDR2G, MC14042BDG, NLV14042BDR2G, NLV14042BDG) are ROHS3 compliant and REACH unaffected, matching the compliance status of CD4042BDRG4.

Q: What packaging formats are available for substitute parts?

A: CD4042BDR is available in Tape & Reel (TR) format. CD4042BDT is available in Tape & Reel (TR) format. MC14042BDR2G is available in Cut Tape (CT) format. NLV14042BDR2G is available in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and order quantities.
