CD74HC4017QPWREP Equivalent & Substitute Parts

Part Overview

The CD74HC4017QPWREP is a decade counter logic integrated circuit manufactured by Texas Instruments. This 10-bit counter IC operates as a single element with asynchronous reset and synchronous timing, designed for applications requiring frequency division and counting functions. The device is classified as Active product status and is RoHS3 compliant. Alternative equivalent parts may be required due to inventory availability, packaging format preferences, or specific qualification requirements for automotive or industrial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4017QPWREP is determined by strict equivalence across the following critical parameters: logic type (Counter, Decade), number of elements (1), number of bits per element (10), direction (Up), reset type (Asynchronous), timing (Synchronous), trigger type (Positive, Negative), voltage supply range (2 V ~ 6 V), operating temperature range (-40°C ~ 125°C), package type (16-TSSOP), and mounting type (Surface Mount).

The substitute parts identified maintain full functional and electrical equivalence across these parameters. Variations in count rate, packaging format (Tape & Reel versus Cut Tape & Digi-Reel), manufacturer, and qualification level (standard versus automotive AEC-Q100) do not affect core substitutability for applications requiring decade counter functionality within the specified electrical and thermal operating envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and full RoHS3 compliance, confirming their suitability for current design implementations. Selection between the main part and substitutes should be based on specific application requirements and supply chain constraints.

The CD74HC4017QPWRG4Q1 carries AEC-Q100 automotive qualification, making it the appropriate choice for automotive-grade applications requiring enhanced reliability and traceability standards. This part is available in Cut Tape and Digi-Reel packaging formats.

The 74HC4017PW,118 manufactured by Nexperia USA Inc. offers a higher count rate specification of 83 MHz compared to the 35 MHz rating of the Texas Instruments variants. This higher performance rating may be beneficial for applications operating at the upper frequency limits of the decade counter function, though all parts operate within the same voltage and temperature envelope.

The CD74HC4017QPWREP remains the primary specification with standard Tape & Reel packaging and Texas Instruments manufacturing origin.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4017QPWRG4Q1 be used as a direct replacement for the CD74HC4017QPWREP?

A: Yes. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications across all critical parameters including logic type, bit width, reset behavior, timing characteristics, voltage supply range, and operating temperature range. The primary differences are packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and automotive AEC-Q100 qualification on the G4Q1 variant. The 16-TSSOP package footprint is identical.

Q: What is the significance of the higher 83 MHz count rate on the 74HC4017PW,118?

A: The 74HC4017PW,118 from Nexperia USA Inc. specifies a maximum count rate of 83 MHz compared to 35 MHz on the Texas Instruments variants. This represents a higher performance rating for the same decade counter function. Both ratings are valid specifications for the same logic family and package. Selection should be based on application frequency requirements and design margins.

Q: Are all three parts suitable for automotive applications?

A: The CD74HC4017QPWRG4Q1 carries explicit AEC-Q100 automotive qualification. The CD74HC4017QPWREP and 74HC4017PW,118 do not specify automotive qualification. For automotive applications requiring formal qualification traceability, the CD74HC4017QPWRG4Q1 is the appropriate selection.

Q: Does packaging format affect electrical performance?

A: No. The Cut Tape (CT) & Digi-Reel format of the CD74HC4017QPWRG4Q1 and the Tape & Reel (TR) format of the other parts are supply chain and handling formats only. The 16-TSSOP package footprint and electrical characteristics remain identical across all three parts.

Q: Are moisture sensitivity requirements the same across all substitutes?

A: Yes. All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage, handling, or assembly processes.
