CD4014BNSR Equivalent & Substitute Parts

Part Overview

The CD4014BNSR is a static shift register IC manufactured by Texas Instruments, designed for parallel or serial to serial data conversion in logic applications. This 8-bit, single-element shift register operates across a wide supply voltage range of 3V to 18V and is housed in a 16-SOIC surface mount package.

The CD4014BNSR carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD4014BNSR is determined by the following critical parameters:

• Logic Function: Shift register with 1 element, 8 bits per element, parallel or serial to serial conversion capability
• Output Configuration: Push-pull output type
• Package Type: 16-SOIC surface mount package
• Supply Voltage Compatibility: Operating range must support the application's voltage requirements
• Temperature Range: Operating temperature specifications must meet or exceed application demands
• Compliance Standards: RoHS3 compliance and REACH status alignment

The HEF4014BT,653 manufactured by Nexperia USA Inc. qualifies as a direct substitute based on matching logic type, element count, bit configuration, function, output type, package format, and compliance certifications. Both components belong to the 4000B logic series and maintain identical pinout and functional characteristics within their respective operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The HEF4014BT,653 is a qualified substitute for the obsolete CD4014BNSR based on functional equivalence and compliance alignment. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility.

Selection considerations are determined by application-specific requirements:

• Supply Voltage Range: The CD4014BNSR supports 3V to 18V operation, while the HEF4014BT,653 operates within 3V to 15V. Applications requiring supply voltages above 15V necessitate the original CD4014BNSR or alternative components rated for extended voltage ranges.

• Temperature Range: The CD4014BNSR operates from -55°C to 125°C, whereas the HEF4014BT,653 operates from -40°C to 85°C. Applications requiring operation below -40°C or above 85°C require the original CD4014BNSR or components with extended temperature specifications.

• Package Dimensions: Both components use 16-SOIC packages with different body widths (5.30mm versus 3.90mm). PCB layout and mechanical clearance requirements determine package suitability.

• Product Status: The HEF4014BT,653 maintains Active product status with higher inventory availability (2867 pcs), supporting long-term supply chain continuity compared to the Obsolete CD4014BNSR.

Frequently Asked Questions (FAQ)

Q: Can the HEF4014BT,653 directly replace the CD4014BNSR in all applications?

A: Direct replacement is possible only when application requirements fall within the HEF4014BT,653 operating parameters. Verify that supply voltage does not exceed 15V and operating temperature remains between -40°C and 85°C. Pinout and functional characteristics are identical.

Q: What are the key differences between these two parts?

A: The primary differences are supply voltage range (CD4014BNSR: 3V-18V; HEF4014BT,653: 3V-15V), operating temperature range (CD4014BNSR: -55°C to 125°C; HEF4014BT,653: -40°C to 85°C), and package body width (5.30mm versus 3.90mm). Functional logic, pinout, and output characteristics are identical.

Q: Why is the CD4014BNSR marked as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The HEF4014BT,653 provides functional equivalence with active manufacturing status, ensuring ongoing availability for new designs and production requirements.

Q: Are there package compatibility concerns between the two parts?

A: Both components use 16-SOIC surface mount packages. The different body widths (5.30mm versus 3.90mm) may affect PCB layout compatibility. Verify footprint dimensions against your PCB design specifications before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CD4014BNSR and HEF4014BT,653 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.
