CD4014BNSRE4 Equivalent & Substitute Parts

Part Overview

The CD4014BNSRE4 is a static shift register IC manufactured by Texas Instruments, part of the 4000B logic series. This 8-bit, single-element shift register supports parallel or serial to serial conversion with push-pull output configuration. The device operates across a wide supply voltage range of 3V to 18V and temperature range of -55°C to 125°C, housed in a 16-SOIC surface mount package.

The CD4014BNSRE4 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4014BNSRE4 is determined by the following critical parameters:

• Logic Type & Function: Must be a shift register supporting parallel or serial to serial conversion
• Bit Configuration: Must be 1 element with 8 bits per element
• Output Type: Must be push-pull configuration
• Package Type: Must be 16-SOIC surface mount package
• Series Compatibility: 4000B logic series devices maintain functional equivalence
• Compliance: RoHS3 compliance required for modern supply chains

The HEF4014BT,653 manufactured by Nexperia USA Inc. meets all substitution criteria. Both devices share identical logic architecture, bit configuration, output characteristics, and package footprint. The primary differences are in supply voltage range and operating temperature specifications, which represent tighter constraints on the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The HEF4014BT,653 is the manufacturer-recommended substitute for the CD4014BNSRE4. Both devices are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements.

Supply Voltage Consideration: The substitute part operates within a narrower supply voltage range (3V ~ 15V) compared to the main part (3V ~ 18V). Applications requiring operation above 15V supply voltage cannot use this substitute without design modification.

Operating Temperature Consideration: The substitute part has a narrower operating temperature range (-40°C ~ 85°C) compared to the main part (-55°C ~ 125°C). Applications requiring operation below -40°C or above 85°C cannot use this substitute without design modification.

Package Footprint Consideration: While both devices use 16-SOIC packaging, the physical dimensions differ (5.30mm width versus 3.90mm width). PCB layout compatibility must be verified before substitution.

Product Status: The substitute part is active and in production, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the HEF4014BT,653 be used as a direct replacement for the CD4014BNSRE4?

A: Functional substitution is possible if your application operates within the substitute part's specifications: supply voltage 3V to 15V and operating temperature -40°C to 85°C. PCB layout must accommodate the different 16-SOIC package width (3.90mm versus 5.30mm).

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

A: The main differences are supply voltage range (CD4014BNSRE4: 3V-18V; HEF4014BT,653: 3V-15V), operating temperature range (CD4014BNSRE4: -55°C to 125°C; HEF4014BT,653: -40°C to 85°C), and 16-SOIC package width (5.30mm versus 3.90mm). Logic function and bit configuration are identical.

Q: Is the substitute part available in production?

A: Yes. The HEF4014BT,653 is an active product with 2867 pieces in stock, compared to the obsolete CD4014BNSRE4 status.

Q: Are both parts RoHS compliant?

A: Yes. Both the CD4014BNSRE4 and HEF4014BT,653 are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What packaging format is the substitute available in?

A: The HEF4014BT,653 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Can I use the substitute if my circuit operates at 18V supply voltage?

A: No. The HEF4014BT,653 maximum supply voltage is 15V. Applications requiring 18V operation require the original CD4014BNSRE4 or alternative parts rated for higher voltage.

Q: Can I use the substitute in applications requiring -55°C operation?

A: No. The HEF4014BT,653 minimum operating temperature is -40°C. Applications requiring -55°C operation require the original CD4014BNSRE4 or alternative parts rated for lower temperature.
