SN74HC165APWR Equivalent & Substitute Parts

Part Overview

The SN74HC165APWR is an 8-bit parallel-in/serial-out shift register manufactured by Texas Instruments, classified as a logic gate and inverter component. This device converts parallel data inputs to serial output format, functioning as a fundamental building block in digital signal processing and data acquisition circuits. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging format or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the SN74HC165APWR is determined by strict equivalence across the following critical parameters: logic type (shift register), bit configuration (8-bit, single element), functional operation (parallel or serial to serial conversion), output type (complementary), supply voltage range (2V ~ 6V), package form factor (16-TSSOP), and surface mount mounting type. Packaging format variation (Tape & Reel versus Cut Tape & Digi-Reel) does not affect electrical or mechanical compatibility. Operating temperature range differences are permitted when the substitute maintains or exceeds the minimum specification of the primary part. All substitute candidates must maintain active product status, RoHS3 compliance, and unlimited moisture sensitivity classification.

Parameter Comparison

Engineering Selection Recommendations

The SN74HC165PWR qualifies as a direct substitute for the SN74HC165APWR based on identical electrical specifications, package geometry, and mounting configuration. Both parts are manufactured by Texas Instruments, carry active product status, and maintain full RoHS3 compliance with unlimited moisture sensitivity rating. The SN74HC165PWR provides an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 85°C), which represents a functional advantage in high-temperature applications. Packaging format differs only in distribution method (Cut Tape & Digi-Reel versus Tape & Reel), which does not affect component performance or PCB assembly compatibility. Selection between these parts should be based on procurement requirements, inventory availability, and packaging format preference for manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can SN74HC165PWR replace SN74HC165APWR in existing designs? A: Yes. Both parts are electrically and mechanically identical 8-bit shift registers in 16-TSSOP surface mount packages with identical supply voltage specifications (2V ~ 6V) and complementary output configuration. Packaging format variation does not affect circuit performance.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging? A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® represent different distribution and handling formats for surface mount components. Both formats contain identical components in the same 16-TSSOP package. Selection depends on manufacturing equipment compatibility and procurement volume requirements.

Q: Does the extended temperature range of SN74HC165PWR affect compatibility? A: No. The SN74HC165PWR operating range (-40°C ~ 125°C) encompasses the SN74HC165APWR range (-40°C ~ 85°C). Extended temperature capability does not create incompatibility; it provides additional operational margin for applications requiring higher temperature tolerance.

Q: Are both parts RoHS3 compliant? A: Yes. Both SN74HC165APWR and SN74HC165PWR are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), meeting current environmental and regulatory requirements for electronic component manufacturing.

Q: What determines substitution eligibility for 74HC165 variants? A: Substitution requires matching logic type (shift register), bit configuration (8-bit single element), functional operation (parallel or serial to serial), output type (complementary), supply voltage range (2V ~ 6V), package form (16-TSSOP), and mounting type (surface mount). Packaging distribution format and operating temperature range extensions do not prevent substitution.
