Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC4040N,652 is determined by the following critical parameters:

Functional Equivalence Requirements:

• Logic Type: Binary Counter
• Number of Bits: 12 Bit
• Number of Elements: 1
• Direction: Up
• Reset Type: Asynchronous
• Trigger Type: Negative Edge
• Voltage Supply Range: 2 V ~ 6 V

Mechanical Compatibility Criteria:

• Package / Case type (16-DIP for through-hole mounting or 16-SOIC for surface mount)
• Mounting Type (Through Hole or Surface Mount)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts are grouped into two categories: direct pin-compatible replacements in 16-DIP through-hole packaging, and surface-mount alternatives in 16-SOIC packaging. All listed substitutes maintain identical functional specifications and electrical parameters within the specified voltage and temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement (Pin-Compatible):

The CD74HC4040E and SN74HC4040N are functionally equivalent through-hole substitutes for the obsolete 74HC4040N,652. Both parts maintain the 16-DIP package format and asynchronous binary counter specifications. The CD74HC4040E offers extended operating temperature range (-55°C to 125°C) compared to the original part (-40°C to 125°C), providing broader environmental compatibility. The SN74HC4040N operates within the original temperature range (-40°C to 85°C) with reduced upper temperature limit. Both substitutes are active products with ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for new designs.

For Surface-Mount Applications:

The 74HC4040D,653 from Nexperia provides a surface-mount alternative in 16-SOIC packaging. This part maintains identical electrical specifications and count rate performance (98 MHz) as the original NXP part, with ROHS3 compliance and active product status. Surface-mount selection is appropriate for PCB designs requiring compact form factors and automated assembly processes.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Active product status for all substitutes ensures long-term availability and supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 74HC4040D,653 (surface mount) be used as a direct replacement for the 74HC4040N,652 (through hole)?

A: No. The 74HC4040D,653 uses 16-SOIC surface-mount packaging while the 74HC4040N,652 uses 16-DIP through-hole packaging. These packages are mechanically incompatible with standard PCB layouts. Surface-mount substitution requires PCB redesign. For direct through-hole replacement, use CD74HC4040E or SN74HC4040N.

Q: What are the key electrical differences between the substitute parts?

A: All substitute parts maintain identical functional specifications: 12-bit binary counter, asynchronous reset, negative edge trigger, and 2 V to 6 V supply voltage. The primary differences are count rate performance (74HC4040D,653 and original: 98 MHz; CD74HC4040E: 35 MHz; SN74HC4040N: 33 MHz) and operating temperature ranges. These differences do not affect functional compatibility in standard applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: Which substitute part offers the widest operating temperature range?

A: The CD74HC4040E operates across -55°C to 125°C, providing the widest temperature range. The original 74HC4040N,652 and 74HC4040D,653 operate from -40°C to 125°C. The SN74HC4040N operates from -40°C to 85°C with a reduced upper temperature limit.

Q: Is the 74HC4040 series suitable for high-speed counting applications?

A: The 74HC4040D,653 and original 74HC4040N,652 support count rates up to 98 MHz. The CD74HC4040E and SN74HC4040N support lower count rates (35 MHz and 33 MHz respectively). Part selection should match application frequency requirements.
