CD4042BD Equivalent & Substitute Parts Reference

Part Overview

The CD4042BD from Texas Instruments is a D-Type Transparent Latch, featuring four independent circuits with differential outputs in a 16-SOIC surface-mount package. It operates across a wide supply voltage range (3V to 18V), is RoHS3 compliant, and maintains a propagation delay of 40ns. This IC has been classified as obsolete, which necessitates the identification of equivalent or substitute parts for continued design support, manufacturing continuity, and maintenance of legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution for CD4042BD is determined strictly by matching the following key parameters: logic type ("D-Type Transparent Latch"), number of independent circuits (4), output type (Differential), supply voltage range (3V ~ 18V), operating temperature range (-55°C ~ 125°C), surface-mount package (16-SOIC), RoHS3 compliance, MSL of 1 (Unlimited), and REACH unaffected status.

Parts are considered equivalent if all these parameters are met without deviation in form factor, mounting type, or major performance characteristics. Minor differences such as tape-and-reel packaging or nominal changes in propagation delay are included as long as electrical and mechanical interfaces are preserved.

Parameter Comparison

Engineering Selection Recommendations

Selection among the listed substitute parts is strictly governed by product status, RoHS3 compliance, REACH status, and MSL rating. All substitute parts listed are RoHS3 compliant, have an MSL of 1 (Unlimited), and are REACH unaffected. Preference should be given to active status parts to ensure ongoing availability and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must match for a valid substitute to CD4042BD?
A: Substitutes must have identical logic type (D-Type Transparent Latch), four independent circuits, differential outputs, supply voltage range of 3V to 18V, compatible delay time and output currents, surface-mount 16-SOIC package, and the same level of environmental and regulatory compliance.

Q2: Are CD4042BDR, MC14042BDR2G, and NLV14042BDR2G functionally interchangeable with the CD4042BD?
A: Based strictly on the provided parameters, these parts are functionally interchangeable as they meet all critical electrical and package criteria.

Q3: Does the packaging type (Tube, Tape & Reel, Cut Tape) affect device equivalency?
A: Packaging type does not alter the electrical or mechanical equivalency of the ICs and is a consideration only for manufacturing or handling processes.

Q4: Do differences in propagation delay and output current affect substitution?
A: All substitute parts listed fall within compatible delay and current specifications as permitted by the primary substitution criteria in the supplied data.

Q5: Is RoHS3 and REACH compliance consistent among all the listed substitutes?
A: All documented substitutes are RoHS3 compliant and REACH unaffected, with an MSL rating of 1 (Unlimited).

Q6: How should product status affect substitute selection?
A: Substitute parts with "Active" product status should be prioritized to ensure long-term availability and supply continuity.

Q7: Are all substitute parts using the same package dimensions as CD4042BD?
A: All substitute components specified have a 16-SOIC (0.154", 3.90mm Width) package, ensuring mechanical compatibility.
