Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN74HC595PW is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Logic Type: Shift Register
• Number of Bits per Element: 8
• Output Type: Tri-State
• Function: Serial to Parallel, Serial
• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply: 2V ~ 6V (minimum requirement)
• RoHS Status: ROHS3 Compliant

Acceptable Variation Parameters:

• Operating Temperature Range: May extend beyond -40°C ~ 85°C (wider ranges are acceptable)
• Packaging Format: Tube, Cut Tape (CT) & Digi-Reel®, or Tape & Reel (TR) are all acceptable
• Manufacturer: Multiple manufacturers produce compatible 74HC595 variants
• Product Status: Active status is preferred; discontinued parts require inventory verification

All substitute parts listed maintain identical electrical specifications and mechanical compatibility with the original SN74HC595PW.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation - Active Status Priority: The SN74HC595PWR (Texas Instruments) and MC74HC595ADTR2G (onsemi) are the preferred substitutes due to active product status and high inventory availability. Both maintain identical electrical specifications to the original SN74HC595PW while offering extended operating temperature ranges.

High-Volume Applications: MC74HC595ADTR2G provides the largest inventory (252800 Pcs) with extended temperature range (-55°C ~ 125°C) and active status, suitable for high-volume production requirements.

Nexperia Alternatives: 74HC595PW,118 and 74HC595PW-Q100,118 from Nexperia USA Inc. offer active status with extended temperature ratings (-40°C ~ 125°C). The Q100 variant includes AEC-Q100 automotive qualification for applications requiring automotive-grade components.

Packaging Considerations: All substitute parts maintain the 16-TSSOP package specification. Selection between Tube, Cut Tape & Digi-Reel®, or Tape & Reel formats depends on assembly process requirements and volume specifications.

Compliance Status: All listed substitutes maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can I use any 74HC595 variant as a direct substitute for the SN74HC595PW?

A: No. The substitute must maintain the 16-TSSOP package, 8-bit configuration, tri-state output, serial-to-parallel function, and 2V ~ 6V supply voltage specification. All listed parts meet these criteria; however, verify your specific application requirements before selection.

Q: What is the difference between the various onsemi part numbers (MC74HC595ADTG, MC74HC595ADTR2G, MM74HC595MTCX, MM74HC595MTC)?

A: These parts are functionally equivalent but differ in packaging format and temperature range. MC74HC595ADTR2G and MC74HC595ADTG support -55°C ~ 125°C operation, while MM74HC595MTCX and MM74HC595MTC support -40°C ~ 85°C. Packaging formats vary between Tube and Cut Tape & Digi-Reel® options.

Q: Is the Nexperia 74HC595PW-Q100,118 suitable for automotive applications?

A: Yes. The 74HC595PW-Q100,118 includes AEC-Q100 automotive qualification and is available in Tape & Reel packaging, making it suitable for automotive-grade applications requiring qualified components.

Q: Why is the SN74HC595PW discontinued while other manufacturers' versions remain active?

A: Product discontinuation decisions are manufacturer-specific and do not reflect component performance or reliability. Multiple manufacturers produce functionally identical 74HC595 shift registers, ensuring design continuity through active substitute parts.

Q: Can I mix different manufacturers' parts in the same production run?

A: Yes. All listed substitutes maintain identical electrical specifications, package dimensions, and pin configurations. However, verify your quality assurance and traceability requirements before mixing manufacturers within a single production batch.

Q: What is the significance of the extended temperature range in MC74HC595ADTR2G (-55°C ~ 125°C)?

A: The extended range accommodates applications requiring operation in extreme temperature environments. If your application operates within the standard -40°C ~ 85°C range, this extended capability provides additional design margin without performance penalty.
