Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC165DB,112 is determined by strict equivalence across the following critical parameters:

Core Functional Parameters:

• Logic Type: Shift Register
• Number of Bits per Element: 8
• Number of Elements: 1
• Output Type: Complementary
• Function: Parallel or Serial to Serial
• Voltage - Supply: 2V ~ 6V
• Operating Temperature: -40°C ~ 125°C (minimum requirement)

Mechanical Compatibility:

• Mounting Type: Surface Mount
• Package / Case: 16-SSOP or 16-TSSOP (both 16-pin TSSOP variants are mechanically compatible with SSOP footprints)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories: direct equivalents (identical package) and compatible alternatives (functionally equivalent with compatible packaging). All listed substitutes maintain the same electrical specifications and compliance certifications as the original part.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Package): SN74HC165DBR from Texas Instruments is the primary direct substitute, offering identical 16-SSOP packaging with active product status and full ROHS3 compliance. This part maintains the original footprint and electrical specifications without requiring PCB layout modifications.

Compatible Alternatives (16-TSSOP Package): Parts designated with 16-TSSOP packaging (MC74HC165ADTR2G, SN74HC165PWR, SN74HC165QPWRG4Q1, SN74HC165QPWRQ1) are mechanically compatible alternatives. The 16-TSSOP package (0.173", 4.40mm width) is narrower than the original 16-SSOP (0.209", 5.30mm width) and will fit within SSOP footprints on existing PCBs. All maintain identical electrical performance and compliance certifications.

Product Status Considerations:

• SN74HC165DBR, SN74HC165PWR, SN74HC165QPWRG4Q1, and SN74HC165QPWRQ1 are active products with ongoing availability.
• MC74HC165ADTR2G is active with extended operating temperature range (-55°C to 125°C).
• SN74HC165QPWREP carries Last Time Buy status; procurement should prioritize active alternatives.
• SN74HC165PW is discontinued at DiGi Electronics; avoid for new designs.

Automotive Grade Option: SN74HC165QPWRG4Q1 and SN74HC165QPWRQ1 include AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade components.

Frequently Asked Questions (FAQ)

Q: Can I use a 16-TSSOP package substitute on a PCB designed for 16-SSOP? A: Yes. The 16-TSSOP package is mechanically compatible with 16-SSOP footprints. The narrower width (4.40mm vs. 5.30mm) allows the component to fit within the original footprint with proper alignment to the center pin row.

Q: What is the difference between the various Texas Instruments part numbers (SN74HC165PW, SN74HC165PWR, SN74HC165QPWREP, SN74HC165QPWRG4Q1, SN74HC165QPWRQ1)? A: These represent different packaging formats and product qualifications. SN74HC165PWR is standard commercial grade in Cut Tape & Digi-Reel format. SN74HC165QPWRG4Q1 and SN74HC165QPWRQ1 are automotive-qualified (AEC-Q100) variants. SN74HC165QPWREP is Last Time Buy status. All maintain identical electrical specifications.

Q: Does the onsemi MC74HC165ADTR2G offer any advantages over Texas Instruments alternatives? A: MC74HC165ADTR2G extends the operating temperature range to -55°C to 125°C, providing wider temperature coverage than the standard -40°C to 125°C specification. This is beneficial for applications requiring enhanced low-temperature performance.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original part's environmental certifications.

Q: Which substitute should I select for new design implementations? A: For standard applications, SN74HC165PWR or SN74HC165QPWRG4Q1 are recommended due to active product status and established supply availability. For automotive applications, select SN74HC165QPWRG4Q1 or SN74HC165QPWRQ1 (AEC-Q100 qualified). For extended temperature range requirements, specify MC74HC165ADTR2G.
