Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74HC595DR are qualified based on the following criteria:

Core Functional Parameters: Logic type (Shift Register), output type (Tri-State), number of elements (1), bits per element (8), and function (Serial to Parallel, Serial) must match exactly.

Electrical Parameters: Supply voltage range (2V ~ 6V) and operating temperature range must be compatible. Parts with extended temperature ranges (-55°C ~ 125°C) are acceptable as they exceed the base specification.

Package Compatibility: All substitute parts use 16-SOIC surface mount packaging with 0.154" width (3.90mm), ensuring mechanical and electrical pin compatibility.

Compliance & Status: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and Active product status.

Packaging Format: Substitutes are available in Cut Tape (CT), Tape & Reel (TR), and Tube formats. Selection depends on procurement and assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, qualifying them for direct replacement in applications using the SN74HC595DR.

Texas Instruments Parts: SN74HC595DRG3 provides parametric equivalence with identical temperature range (-40°C ~ 85°C) and package dimensions, differing only in packaging format (Tape & Reel). CD74HC595DWR offers extended temperature range (-55°C ~ 125°C) but features a wider package body (7.50mm vs. 3.90mm), requiring PCB layout verification before substitution.

onsemi Parts: MC74HC595ADR2G and MC74HC595ADG provide extended temperature operation (-55°C ~ 125°C) with identical package dimensions to the base part. MM74HC595M and MM74HC595MX match the original temperature specification (-40°C ~ 85°C) with standard packaging options.

Nexperia Parts: 74HC595D,118 and 74HC595D-Q100,118 offer extended temperature range (-40°C ~ 125°C). The Q100 variant includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.

Diodes Incorporated: 74HC595S16-13 provides extended temperature range (-40°C ~ 125°C) in Tape & Reel format with limited inventory availability.

Frequently Asked Questions (FAQ)

Q: Can CD74HC595DWR replace SN74HC595DR directly on the PCB?

A: CD74HC595DWR uses a 16-SOIC package with 7.50mm body width compared to the 3.90mm width of SN74HC595DR. PCB footprint compatibility must be verified before substitution, as the wider package may not fit existing pad layouts.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual component strips suitable for manual assembly or small-volume production. Tape & Reel (TR) packaging supplies components on continuous reels for automated pick-and-place assembly equipment. Both formats contain identical components; selection depends on assembly process requirements.

Q: Are all substitute parts pin-compatible with SN74HC595DR?

A: All substitute parts listed use 16-SOIC surface mount packaging with matching pin configurations. Electrical and functional pin assignments are identical across all qualified substitutes.

Q: Which substitute offers the widest operating temperature range?

A: MC74HC595ADR2G, MC74HC595ADG, 74HC595D,118, 74HC595D-Q100,118, and 74HC595S16-13 all support -55°C ~ 125°C operating temperature, extending beyond the base SN74HC595DR specification of -40°C ~ 85°C.

Q: Is the 74HC595D-Q100,118 suitable for automotive applications?

A: Yes. The 74HC595D-Q100,118 carries AEC-Q100 automotive qualification and Tape & Reel packaging, making it suitable for automotive-grade circuit designs.

Q: What is MSL Level 1 and why does it matter?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited shelf life without moisture control requirements. All listed parts maintain MSL Level 1, eliminating moisture-related handling constraints during storage and assembly.

Q: Can I use onsemi parts as direct replacements for Texas Instruments parts?

A: Yes. MC74HC595ADR2G, MC74HC595ADG, MM74HC595M, and MM74HC595MX are functionally equivalent to SN74HC595DR with identical logic specifications, supply voltage, and package dimensions. Extended temperature variants offer additional operational margin.
