74HC4017N,652 Equivalent & Substitute Parts

Part Overview

The 74HC4017N,652 is a decade counter logic IC manufactured by NXP USA Inc., designed for counting applications requiring a 10-bit positive/negative trigger counter in a 16-DIP through-hole package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The 74HC4017 series provides decade counting functionality across multiple manufacturers and package configurations, enabling design flexibility while maintaining core electrical compatibility.

Substitute Part Grouping Explanation

Substitution of the 74HC4017N,652 is determined by the following criteria:

Electrical Compatibility Requirements:

• Base product number must be 74HC4017
• Logic type must be Counter, Decade
• Number of bits per element must be 10 Bit
• Trigger type must support Positive and Negative
• Supply voltage range must encompass 2 V ~ 6 V
• Reset function must be Asynchronous
• Timing must be Synchronous

Mechanical Compatibility Requirements:

• Package type determines physical fit (through-hole DIP vs. surface-mount SOIC)
• Pin count must remain 16 pins
• Mounting type affects PCB assembly method

Compliance Requirements:

• RoHS3 compliance preferred for new designs
• REACH Unaffected status maintained across all substitutes

The substitute parts are grouped into two categories: direct pin-compatible replacements (same package type) and functional equivalents (different package type but identical electrical performance).

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole PCB Assemblies:

CD74HC4017E (Texas Instruments) is the primary substitute for 74HC4017N,652 in through-hole applications. This part maintains identical package geometry (16-DIP), is currently in active production status, and carries ROHS3 compliance certification. The extended operating temperature range (-55°C ~ 125°C) provides additional thermal margin compared to the original part. Count rate specification of 35 MHz remains within acceptable performance parameters for decade counter applications.

For Surface-Mount PCB Assemblies:

74HC4017D,652 (Nexperia USA Inc.) provides functional equivalence in a 16-SOIC surface-mount package. This part matches the original 83 MHz count rate specification and maintains ROHS3 compliance. Surface-mount configuration enables higher-density PCB layouts. Nexperia is the successor entity to NXP's logic IC division, ensuring design continuity.

Compliance Considerations:

CD74HC4017M (Harris Corporation) is electrically compatible but carries RoHS non-compliant status. This part is suitable only for applications where RoHS compliance is not required. Extended operating temperature range (-55°C ~ 125°C) is available but does not offset the compliance limitation for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4017E directly replace 74HC4017N,652 without PCB modification?

A: Yes. Both parts use identical 16-DIP through-hole package geometry with 0.300" (7.62mm) spacing. Pin assignments are functionally equivalent. No PCB layout changes are required.

Q: What is the difference between the 83 MHz and 35 MHz count rate specifications?

A: Count rate defines the maximum frequency at which the counter can reliably operate. The 74HC4017N,652 and 74HC4017D,652 specify 83 MHz maximum, while CD74HC4017E and CD74HC4017M specify 35 MHz maximum. Selection depends on application frequency requirements. Both rates support standard decade counter applications operating at typical logic frequencies.

Q: Is 74HC4017D,652 a direct replacement for 74HC4017N,652?

A: No. 74HC4017D,652 uses a 16-SOIC surface-mount package versus the 16-DIP through-hole package of 74HC4017N,652. Electrical function is identical, but PCB footprint and assembly method differ. This part is suitable for new designs requiring surface-mount technology.

Q: Why is CD74HC4017M listed if it is RoHS non-compliant?

A: CD74HC4017M is electrically and functionally equivalent to 74HC4017N,652 and remains available in inventory. It is included for reference in applications where RoHS compliance is not a regulatory requirement. New designs should prioritize ROHS3-compliant alternatives.

Q: What is the significance of the extended temperature range in CD74HC4017E and CD74HC4017M?

A: Both parts specify -55°C ~ 125°C operating temperature versus -40°C ~ 125°C for the original part. The extended lower temperature limit provides additional margin for applications operating in cold environments. This does not affect substitution compatibility; it represents an enhanced specification.

Q: Are all substitute parts pin-compatible with the original 74HC4017N,652?

A: CD74HC4017E is pin-compatible (same 16-DIP package). 74HC4017D,652 and CD74HC4017M are functionally equivalent but use different packages (16-SOIC surface-mount). Pin compatibility applies only to through-hole DIP packages.
