CD4050BEE4 Equivalent & Substitute Parts

Part Overview

The CD4050BEE4 is a 6-channel, non-inverting buffer IC manufactured by Texas Instruments, designed for logic signal buffering applications across a wide supply voltage range of 3V to 18V. This device features push-pull output configuration and is housed in a 16-pin DIP package suitable for through-hole mounting. The CD4050BEE4 is classified as an Active product with full RoHS3 compliance and REACH unaffected status, making it suitable for modern electronic applications requiring environmental compliance.

Substitute parts are necessary when the primary part becomes unavailable due to inventory constraints, supply chain disruptions, or when alternative sourcing options are required for cost optimization or logistics purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4050BEE4 is determined by strict parametric matching across the following critical criteria:

Functional Parameters: Logic type (Buffer, Non-Inverting), number of elements (6), bits per element (1), and output configuration (Push-Pull) must be identical.

Electrical Parameters: Output current specifications (8mA high, 48mA low) and supply voltage range (3V ~ 18V) must match exactly.

Thermal Parameters: Operating temperature range (-55°C ~ 125°C) must be maintained.

Physical Parameters: Package type (16-DIP), mounting method (Through Hole), and pin configuration (16-PDIP) must be identical to ensure mechanical and electrical compatibility.

Series Compatibility: Parts must belong to the 4000B logic series to ensure functional equivalence.

The CD4050BE from Harris Corporation meets all parametric requirements for direct substitution, despite differences in product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

CD4050BEE4 (Texas Instruments): This is the primary specification part with Active product status. It carries full RoHS3 compliance and REACH unaffected certification, making it the preferred choice for applications requiring environmental compliance documentation and long-term supply assurance.

CD4050BE (Harris Corporation): This substitute part provides identical electrical and mechanical functionality with matching parametric specifications. However, it carries Obsolete product status and RoHS non-compliant classification. Selection of this part should be limited to applications where compliance certifications are not required or where existing inventory must be utilized. The obsolete status indicates limited future availability.

Selection between these parts should be based on compliance requirements, supply chain availability, and application-specific regulatory constraints rather than functional performance, as both parts are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can CD4050BE be used as a direct replacement for CD4050BEE4?

A: Yes, from a functional and electrical standpoint. Both parts are parametrically identical in logic type, element count, output configuration, current ratings, supply voltage range, operating temperature, and package specifications. However, compliance and product status differ. CD4050BE is obsolete and RoHS non-compliant, while CD4050BEE4 is active and RoHS3 compliant.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must be identical: 6-element non-inverting buffer configuration, 1 bit per element, push-pull output, 8mA/48mA output current, 3V-18V supply voltage, -55°C to 125°C operating temperature, 16-DIP through-hole package, and 4000B series classification.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use identical 16-DIP (0.300", 7.62mm) through-hole packages with 16-PDIP pin configuration. They are mechanically and electrically interchangeable at the board level.

Q: Why would I choose the obsolete CD4050BE over the active CD4050BEE4?

A: The CD4050BE should only be selected if existing inventory must be consumed or if the application has no compliance requirements. For new designs or applications requiring RoHS certification, the CD4050BEE4 is the appropriate choice.

Q: Are there any supply voltage or temperature limitations I should be aware of?

A: Both parts operate identically across the 3V to 18V supply range and -55°C to 125°C temperature range. No derating or operational limitations exist between the two parts within these specifications.

Q: What is the base product number for these parts?

A: The base product number is CD4050, which identifies the functional family. The suffixes (BEE4 and BE) indicate manufacturer, packaging, and variant specifications.
