Key Parameters

Substitute Part Grouping Explanation

Substitution for the SN74HC165PWT is determined by strict equivalence across the following critical parameters:

• Logic Type: Shift Register (8-bit, 1 element)
• Function: Parallel or Serial to Serial conversion
• Output Type: Complementary
• Supply Voltage Range: 2V ~ 6V
• Package / Case: 16-TSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain these core electrical and mechanical parameters. Variations in operating temperature range, product status, packaging format (Cut Tape vs. Tape & Reel), and automotive qualification do not affect functional interchangeability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring immediate procurement with maximum availability, SN74HC165PWR (Texas Instruments, Active status, 5200 units in stock) or 74HC165PW,118 (Nexperia USA Inc., Active status, 17757 units in stock) are primary selections. Both maintain identical electrical specifications and standard operating temperature range.

For automotive applications requiring AEC-Q100 qualification, SN74HC165QPWRG4Q1 (Texas Instruments) or 74HC165PW-Q100,118 (Nexperia USA Inc.) are appropriate selections. These parts carry automotive-grade certification while maintaining full functional equivalence.

For extended operating temperature range applications (-55°C lower limit), MC74HC165ADTR2G (onsemi, Active status) provides superior thermal performance compared to the standard -40°C minimum specification.

Avoid NLV74HC165ADTR2G (onsemi) due to Obsolete product status, despite its automotive qualification and extended temperature range.

Frequently Asked Questions (FAQ)

Q: Can SN74HC165PWR be used as a direct replacement for SN74HC165PWT?

A: Yes. Both parts share identical electrical specifications, supply voltage range (2V ~ 6V), operating temperature range (-40°C ~ 125°C), 8-bit shift register function, and 16-TSSOP package. The primary difference is packaging format (Cut Tape & Digi-Reel® versus the original specification).

Q: What is the difference between automotive-qualified and standard versions?

A: Automotive-qualified parts (SN74HC165QPWRG4Q1, 74HC165PW-Q100,118, NLV74HC165ADTR2G) carry AEC-Q100 certification, indicating compliance with automotive reliability and quality standards. Standard versions lack this certification. Electrical and mechanical parameters remain identical.

Q: Does operating temperature range affect substitution compatibility?

A: Operating temperature range does not affect functional interchangeability for standard applications. MC74HC165ADTR2G offers extended lower temperature operation (-55°C minimum versus -40°C), providing additional capability without reducing performance in standard temperature ranges.

Q: Are there packaging format restrictions for substitution?

A: All substitute parts use identical 16-TSSOP surface mount packaging. Packaging format variations (Cut Tape & Digi-Reel® versus Tape & Reel) relate to supply and handling only and do not affect electrical or mechanical compatibility.

Q: Which substitute part has the highest current inventory?

A: 74HC165PW,118 (Nexperia USA Inc.) has the highest inventory at 17757 units, followed by 74HC165PW-Q100,118 at 8986 units.

Q: Can parts from different manufacturers be used interchangeably?

A: Yes. SN74HC165 series parts from Texas Instruments, MC74HC165 from onsemi, and 74HC165 from NXP Semiconductors and Nexperia USA Inc. are functionally equivalent when electrical and mechanical parameters match. All listed substitutes maintain the required specifications.
