CD74HC4050NSR Equivalent & Substitute Parts

Part Overview

The CD74HC4050NSR is a non-inverting buffer IC manufactured by Texas Instruments, designed for logic signal buffering applications. This 6-element buffer operates across a 2V to 6V supply voltage range with push-pull output configuration. The device is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent functional performance, electrical specifications, and package compatibility can be maintained across alternative manufacturers while meeting the same operational requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4050NSR is determined by equivalence in the following critical parameters:

• Logic Type: Buffer, Non-Inverting (functional equivalence)
• Number of Elements: 6 (channel count)
• Number of Bits per Element: 1 (bit configuration)
• Output Type: Push-Pull (output stage configuration)
• Current - Output High, Low: 5.2mA, 5.2mA (drive capability)
• Voltage - Supply: 2V ~ 6V (operating range)
• Mounting Type: Surface Mount (assembly compatibility)
• Package / Case: 16-SOIC (footprint compatibility)
• Series: 74HC (logic family)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

The 74HC4050D,653 manufactured by Nexperia USA Inc. meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the CD74HC4050NSR and 74HC4050D,653 maintain Active product status and full compliance with ROHS3 and REACH regulations. The devices are functionally equivalent across all critical electrical parameters including logic type, element count, output configuration, and supply voltage range. Both devices are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

The primary distinction between these parts is the operating temperature range and package body width. The CD74HC4050NSR supports -55°C to 125°C operation, while the 74HC4050D,653 operates from -40°C to 125°C. The Nexperia device features a narrower 16-SOIC package body (3.90mm versus 5.30mm width), which may provide space optimization benefits in compact PCB layouts while maintaining identical electrical performance and pin compatibility.

Frequently Asked Questions (FAQ)

Q: Are the CD74HC4050NSR and 74HC4050D,653 pin-compatible?

A: Yes. Both devices are 16-SOIC packages with identical pin configurations and electrical specifications for logic type, element count, output type, and supply voltage range.

Q: What is the difference in package body width between these parts?

A: The CD74HC4050NSR uses a 16-SOIC package with 5.30mm body width, while the 74HC4050D,653 uses a 16-SOIC package with 3.90mm body width. Both are surface-mount compatible with standard PCB footprints, though the narrower package may offer space advantages in dense layouts.

Q: Can the 74HC4050D,653 be used in applications requiring -55°C operation?

A: No. The 74HC4050D,653 is rated for -40°C to 125°C operation. Applications requiring -55°C minimum operating temperature must use the CD74HC4050NSR.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the CD74HC4050NSR and 74HC4050D,653 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution is based on matching logic type (Buffer, Non-Inverting), element count (6), bits per element (1), output type (Push-Pull), output current (5.2mA high and low), supply voltage range (2V ~ 6V), and package type (16-SOIC). Operating temperature range and package body width are secondary considerations dependent on application requirements.
